Several certification standards/guidelines now recommend and/or mandate the development of assurance cases for software-intensive systems, e.g., defense (UK MoD DS-0056), aviation (CAP 670, FAA’s operational approval guidance for unmanned aircraft systems), automotive (ISO 26262), and healthcare (FDA infusion pumps total product lifecycle guidance). As such, there is a need to develop models, techniques and tools that target the development of assurance arguments for software.
The goals of the 2018 Workshop on Assurance Cases for Software-intensive Systems (ASSURE 2018) are to:
- explore techniques for creating/assessing assurance cases for software-intensive systems;
- examine the role of assurance cases in the engineering lifecycle of critical systems;
- identify the dimensions of effective practice in the development and evaluation of assurance cases;
- investigate the relationship between dependability techniques and assurance cases; and,
- identify critical research challenges and define a roadmap for future development.
We solicit high-quality contributions: research, practice, tools and position papers on the application of assurance case principles and techniques to assure that the dependability properties of critical software-intensive systems have been met.
Papers should attempt to address the workshop goals in general.
Topics
Topics of interest include, but are not limited to:
- Assurance issues in emerging paradigms, e.g., adaptive and autonomous systems, including self-driving cars, unmanned aircraft systems, complex health care and decision making systems, etc.
- Standards: Industry guidelines and standards are increasingly requiring the development of assurance cases, e.g., the automotive standard ISO 26262 and the FDA guidance on the total product lifecycle for infusion pumps.
- Certification and Regulations: The role and usage of assurance cases in the certification of critical systems, as well as to show compliance to regulations.
- Empiricism: Empirical assessment of the applicability of assurance cases in different domains and certification regimes.
- Dependable architectures: How do fault-tolerant architectures and design measures such as diversity and partitioning relate to assurance cases?
- Dependability analysis: What are the relationships between dependability analysis techniques and the assurance case paradigm?
- Safety and security co-engineering: What are the impacts of security on safety, particularly safety cases, and how can safety and security cases (e.g., as proposed in ISO 26262 and SAE J 3061 respectively) be reconciled?
- Tools: Using the output from software engineering tools (testing, formal verification, code generators) as evidence in assurance cases / using tools for the modeling, analysis and management of assurance cases.
- Application of formal techniques for the creation, analysis, reuse, and modularization of arguments.
- Exploration of relevant techniques for assurance cases for real-time, concurrent, and distributed systems.
- Assurance of software quality attributes, e.g., safety, security and maintainability, as well as dependability in general, including tradeoffs, and exploring notions of the quality of assurance cases themselves.
- Domain-specific assurance issues, in domains such as aerospace, automotive, healthcare, defense and power.
- Reuse and Modularization: Contracts and patterns for improving the reuse of assurance case structures.
- Relations between different formalisms and paradigms of assurance and argumentation, such as Goal Structuring Notation, STAMP, IBIS, and goal-oriented formalisms such as KAOS.

235 Years Ago: Herschel Discovers Saturn’s Moon Enceladus
On Aug. 29, 1789, German-born British astronomer William Herschel observed a tiny bright dot orbiting around Saturn. His son later named the object Enceladus. Because of its distance from Earth and proximity to bright Saturn, for the next two centuries little remained known about Enceladus other than its size, orbital parameters, and that it held the honor as the most reflective body in the solar system. It took the Voyager flybys through the Saturn system in the early 1980s and especially the detailed observations between 2005 and 2015 by the Saturn orbiter Cassini to reveal Enceladus as a truly remarkable world, interacting with Saturn and its rings. Harboring a subsurface ocean of salty water, Enceladus may possibly be hospitable to some forms of life.

Herschel’s previous astronomical accomplishments include the discovery of Uranus in 1781 and two of its moons, Oberon and Titania, in 1787. He also catalogued numerous objects he termed nebulae, but remained frustrated by the limitations of telescopes of his age. He began to build ever larger instruments, finally building the world’s largest reflecting telescope of its time. At 40 feet long, and with a 49-inch diameter primary mirror weighing a ton, it looked impressive although its optical characteristics did not advance the field as much as he had hoped. Nevertheless, Herschel used this telescope to observe Saturn and its five known moons, looking for others. On Aug. 28, 1789, he observed a bright point orbiting the planet and believed he had discovered a sixth moon. On Sept. 17, he discovered a seventh moon orbiting the ringed planet. He did not name these moons, that task fell to his son John who believed Saturn’s moons should be named after the Titans of Greek mythology. He named the first moon Enceladus and the second Mimas.

For nearly two centuries, Enceladus remained not much more than a point of light orbiting Saturn, just another icy moon in the outer solar system. Astronomers estimated its diameter at around 310 miles and its orbital period around Saturn at 1.4 days, with a mean distance from the planet’s center of 148,000 miles. Enceladus has the distinction as one of the brightest objects in the solar system, reflecting almost 100 percent of the Sun’s light. Unusual telescope observations during the 20th century showed an increase in brightness on its trailing side, with no known explanation at the time. In 1966, astronomers discovered a diffuse ring around Saturn, the E-ring, and found in 1980 that its density peaked near Enceladus. The Voyager 1 spacecraft flew within 125,570 miles of Enceladus during its passage through the Saturn system on Nov. 12, 1980. Its twin Voyager 2 came within 54,000 miles on Aug. 26, 1981, during its flyby. These close encounters enabled the spacecraft to return the first detailed images of the moon, showing various terrains, including heavily cratered areas as well as smooth crater-free areas, indicating a very young surface.
Left: False color image of Enceladus from Cassini showing the tiger stripes at bottom. Middle: Limb view of Enceladus showing plumes of material emanating from its surface. Right: Cassini image of Enceladus backlit by the Sun showing the fountain-like plumes of material.
After the Cassini spacecraft entered orbit around Saturn in July 2004, our understanding of Enceladus increased tremendously, and of course raised new questions. Between 2005 and 2015, Cassini encountered Enceladus 22 times, turning its various instruments on the moon to unravel its secrets. It noted early on that the moon emitted gas and dust or ice particles and that they interacted with the E-ring. Images of the moon’s south polar region revealed cracks on the surface and other instruments detected a huge cloud of water vapor over the area. The moon likely had a liquid subsurface and some of this material reached the outside through these cracks. Scientists named the most prominent of these areas “tiger stripes” and later observations confirmed them as the source of the most prominent jets. During the most daring encounter in October 2015, Cassini came within 30 miles of the Enceladus’ surface, flying through the plume of material emanating from the moon. Analysis of the plumes revealed an organic brew of volatile gases, water vapor, ammonia, sodium salts, carbon dioxide, and carbon monoxide. These plumes replenish Saturn’s E-ring, and some of this material enters Saturn’s upper atmosphere, an interaction unique in the solar system. More recently, the James Webb Space Telescope imaged the water vapor plume emanating from Enceladus’ south pole, extending out 40 times the size of the moon itself. The confirmation of a subsurface ocean of salty water has led some scientists to postulate that Enceladus may be hospitable to some forms of life, making it a potential target for future exploration. Enceladus may yet have more surprises, even as scientists continue to pore over the data returned by Cassini.

A new set of NASA science experiments and technology demonstrations will arrive at the lunar South Pole in 2027 following the agency’s latest CLPS (Commercial Lunar Payload Services) initiative delivery award. Intuitive Machines of Houston will receive $116.9 million to deliver six NASA payloads to a part of the Moon where nighttime temperatures are frigid, the terrain is rugged, and the permanently shadowed regions could help reveal the origin of water throughout our solar system.
Part of the agency’s broader Artemis campaign, CLPS aims to conduct science on the Moon for the benefit of all, including experiments and demos that support missions with crew on the lunar surface.
“This marks the 10th CLPS delivery NASA has awarded, and the fourth planned for delivery to the South Pole of the Moon,” said Joel Kearns, deputy associate administrator for exploration, Science Mission Directorate, NASA Headquarters in Washington. “By supporting a robust cadence of CLPS flights to a variety of locations on the lunar surface, including two flights currently planned by companies for later this year, NASA will explore more of the Moon than ever before.”
NASA has awarded Intuitive Machine’s four task orders. The company delivered six NASA payloads to Malapert A in the South Pole region of the Moon in early 2024. With this lunar South Pole delivery, Intuitive Machines will be responsible for payload integration, launch from Earth, safe landing on the Moon, and mission operations.
“The instruments on this newly awarded flight will help us achieve multiple scientific objectives and strengthen our understanding of the Moon’s environment,” said Chris Culbert, manager of the CLPS initiative at NASA’s Johnson Space Center in Houston. “For example, they’ll help answer key questions about where volatiles – such as water, ice, or gas – are found on the lunar surface and measure radiation in the South Pole region, which could advance our exploration efforts on the Moon and help us with continued exploration of Mars.”
The instruments, collectively expected to be about 174 pounds (79 kilograms) in mass, include:
- The Lunar Explorer Instrument for Space Biology Applications will deliver yeast to the lunar surface and study its response to radiation and lunar gravity. The payload is managed by NASA’s Ames Research Center in Silicon Valley, California.
- Package for Resource Observation and In-Situ Prospecting for Exploration, Characterization and Testing is a suite of instruments that will drill down to 3.3 feet (1 meter) beneath the lunar surface, extract samples, and process them in-situ in a miniaturized laboratory, to identify possible volatiles (water, ice, or gas) trapped at extremely cold temperatures under the surface. This suite is led by ESA (European Space Agency).
- The Laser Retroreflector Array is a collection of eight retroreflectors that will enable lasers to precisely measure the distance between a spacecraft and the reflector on the lander. The array is a passive optical instrument and will function as a permanent location marker on the Moon for decades to come. The retroflector array is managed by NASA’s Goddard Space Flight Center in Greenbelt, Maryland.
- The Surface Exosphere Alterations by Landers will investigate the chemical response of lunar regolith to the thermal, physical, and chemical disturbances generated during a landing, and evaluate contaminants injected into the regolith by the lander. It will give insight into how a spacecraft landing might affect the composition of samples collected nearby. This payload is managed by NASA Goddard.
- The Fluxgate Magnetometer will characterize certain magnetic fields to improve the understanding of energy and particle pathways at the lunar surface and is managed by NASA Goddard.
- The Lunar Compact Infrared Imaging System will deploy a radiometer – a device that measures infrared wavelengths of light – to explore the Moon’s surface composition, map its surface temperature distribution, and demonstrate the instrument’s feasibility for future lunar resource utilization activities. The imaging system is managed by the Laboratory for Atmospheric and Space Physics at the University of Colorado at Boulder.
Under CLPS, multiple commercial deliveries to different geographic regions will help NASA conduct science and continue working toward a long-term human presence on the Moon. Future deliveries will include sophisticated science experiments, and technology demonstrations as part of the agency’s Artemis campaign. Two upcoming CLPS flights slated to launch near the end of 2024 will deliver NASA payloads to the Moon’s nearside and South Pole, including the Intuitive Machines-2 delivery of NASA’s first on-site demonstration of searching for water and other chemical compounds 3.3 feet below the surface of the Moon, using a drill and mass spectrometer.

NASA Celebrates 25 Years of High School Aerospace Scholars
For 25 years, the Office of STEM Engagement (OSTEM) at NASA’s Johnson Space Center has inspired and provided high school students across the state of Texas with NASA-focused learning experiences through the High School Aerospace Scholars (HAS) program. The OSTEM team celebrated the milestone on Monday, July 29 at Johnson’s Gilruth Center with poster sessions, special presentations, and a networking reception.
Fifty-one students who participated in the 2024 High School Aerospace Scholars program were invited to NASA’s Johnson Space Center in Houston to participate in an on-site experience. NASA/James BlairAn authentic STEM learning experience for Texas high school juniors, HAS provides opportunities for students to engage with NASA’s missions and become the next generation of explorers. The year-long program begins in the fall with an online, state-aligned STEM learning experience focused on Earth science, technology, aeronautics, the solar system, the International Space Station, and NASA’s Moon to Mars exploration approach. Students engage in approximately four months of virtual learning through curriculum including interactive lessons, rubric-based activities, and quizzes.
Students who complete the online courses with an overall average of 70% or greater receive an invitation to a five-day virtual summer experience called Moonshot. While actively mentored by NASA scientists and engineers, students work with a team to complete an Artemis-themed Moon to Mars mission and design challenge. The summer session also includes numerous gamified activities and guidance towards pathways to STEM careers.
High School Aerospace Scholars collaborated on an engineering design challenge during their on-site experience at Johnson Space Center. NASA/Bill StaffordThe top performing Moonshot teams are then invited to a four-day residential experience at Johnson, with lodging, meals, and transportation provided at no cost to the students. During the on-site session, students participate in NASA facility tours, complete engineering design challenges, and meet with NASA scientists and engineers who offer guidance on STEM careers. At the completion of the program, students can earn up to one full science elective credit for school.
The HAS 25th anniversary celebration coincided with this year’s on-site experience. During the 2023-2024 school year, 798 students participated in the HAS online course, with 359 advancing to the summer Moonshot experience. The top six Moonshot teams (51 students) were invited to Johnson.
High School Aerospace Scholars presented their Moonshot projects to Johnson Space Center team members during a poster session. NASA/James BlairThe 51 selected students kicked off the anniversary celebration with a poster session to present their Moonshot projects. Following the session, students heard from Johnson Center Director Vanessa Wyche and Deputy Director Steve Koerner during a fireside chat. Speakers included Pam Melroy, NASA Deputy Administrator; Arturo Sanchez, Johnson External Relations Office Director; Mike Kincaid, NASA OSTEM Associate Administrator; Greg Bonnen, member of the Texas House of Representatives; Brian Freedman, Bay Area Houston Economic Partnership President; and Shelly Tornquist, director of Texas A&M University College of Engineering’s education outreach program, Spark!

Over 150 guests stopped by the exhibit, which featured a HAS video montage and the opportunity to touch a lunar sample. Several of the visitors communicated their appreciation for HAS, noting the program has made significant impact on their children’s motivation, school performance, and career paths. Many alumni have gone on to pursue careers within STEM, including nearly 30 HAS participants who have been employed by NASA within the past five years.
2024 High School Aerospace Scholars connected with program alumni and HAS mentors during the Alumni Social held onsite at Johnson Space Center. NASA/Helen Arase VargasFor alumni who wish to continue their experience beyond the year-long program, HAS recently launched a mentorship course, for high school seniors. The course contains modules about leadership and STEM career opportunities and was designed to continue to engage the students as they prepare for the next step in their education or to launch their careers. Alumni also act as an additional layer of support for the junior scholars as they navigate their HAS experience.
HAS is made possible through collaborations among NASA, the State of Texas, Bay Area Houston Economic Partnership, Texas A&M Engineering Experiment Station, Houston Livestock Show and Rodeo, and Rotary National Award for Space Achievement.
Applications will reopen in September for students interested in participating in the 2025 HAS experience.
NASA G-IV Plane Will Carry Next-Generation Science Instrument
2 min read
Preparations for Next Moonwalk Simulations Underway (and Underwater) In a series of baseline flights beginning on June 24, 2024, the G-IV aircraft flew over the Antelope Valley to analyze aircraft performance. To accommodate a new radar instrument developed by JPL, NASA’s Airborne Science Program has selected the Gulfstream-IV aircraft to be modified and operated by Armstrong Flight Research Center in Edwards, California and will accommodate new instrumentation on board in support of the agency’s science mission directorate. Baseline flights began at NASA Armstrong in June 2024NASA/Carla ThomasIn June 2024, a new tail number swept the sky above NASA’s Armstrong Flight Research Center in Edwards, California. Pilots conducted flights of a Gulfstream IV (G-IV) to evaluate its handling characteristics and to familiarize pilots with it before it begins structural modifications. The research plane is joining the center’s fleet serving NASA’s Airborne Science program.
The G-IV will carry the Next Generation Airborne Synthetic Aperture Radar (AIRSAR-NG), which sends and receives microwave signals to collect information about Earth’s topographic features and how they change over time. The goal for the team at NASA Armstrong is to modify the G-IV to accommodate three radars simultaneously.
“The AIRSAR-NG will be composed of three different Synthetic Aperture Radar antennas in one instrument to provide new insight into Earth’s surface more efficiently,” said Yunling Lou, principal investigator for the instrument at NASA’s Jet Propulsion Laboratory in Southern California. “The capabilities of this new instrument will facilitate new techniques, such as three-dimensional imaging, that will be useful for future space-borne missions.”
With those and other modifications being made, the G-IV will also be able to accommodate an increased load of science instruments, which could enable NASA to support more dynamic airborne science missions.
“This aircraft will aid Armstrong in continuing our long history of supporting airborne science for the agency and maintain the expertise in conducting successful science missions for years to come,” said Franzeska Becker, the G-IV project manager at NASA Armstrong.
Transferred in February from NASA’s Langley Research Center in Hampton, Virginia, the G-IV will undergo additional modifications overseen by NASA Armstrong’s team. Their goal is to enrich the agency’s airborne science program by outfitting the aircraft to function as a more capable and versatile research platform.
The knowledge and expertise of professionals at NASA centers like Armstrong (G-IV, ER-2, C-20) and Langley (777, G-III) will help enable the agency to produce a well-defined and airworthy platform for science instruments and airborne science missions.

Saharan Dust in the Wind
The Suomi NPP satellite acquired this image of a plume of Saharan dust as winds lofted it over the Atlantic Ocean on Aug. 24, 2024.
The Sahara Desert is Earth’s largest source of airborne dust, and the particles can travel for thousands of miles. From late spring to early fall, it is common for the dry, dusty Saharan Air Layer to carry the particles westward across the Atlantic Ocean high in the atmosphere. Saharan Air Layer activity subsides after mid-August, according to NOAA, making it less likely that the plume shown here is bound for a transoceanic journey. Instead, it arcs to the north after blowing out over the ocean. Earlier in the summer, however, several clouds of fine dust from the Sahara reached the United States, creating hazy skies over Texas.

Aaron Vigil Helps Give SASS to Roman Space Telescope
The stars in the big Wyoming skies inspired Aaron Vigil as a child to dream big. Today, he’s a mechanical engineer working on the Solar Array Sun Shield (SASS) for the Nancy Grace Roman Space Telescope at Goddard.
Name: Aaron Vigil
Title: Mechanical Engineer
Formal Job Classification: Aerospace Technology, Flight Structures
Organization: Mechanical Engineering, Engineering and Technology Directorate (Code 543)
What do you do and what is most interesting about your role here at Goddard? How do you help support Goddard’s mission?
I currently work on the Solar Array Sun Shield (SASS) for the Nancy Grace Roman Space Telescope. I support daily integration and testing tasks related to the SASS assembly. I spend a lot of my time working with Goddard mechanical technicians and other engineers to execute test plans and procedures to assemble, test, and integrate SASS hardware.
What interests you about space?
I grew up in rural Wyoming. I did a lot of hiking, hunting, fishing, and camping. We were on the mountains constantly. I remember being up at night, sitting around the campfire with my family, looking up at the stars.
I was fascinated and captivated! I wanted to learn more about space.
“I currently work on the Solar Array Sun Shield (SASS) for the Nancy Grace Roman Space Telescope,” said Aaron. “I support daily integration and testing tasks related to the SASS assembly.”Photo credit: NASA/Chris GunnWhat brought you to Goddard?
In 2019, I began a B.S. in mechanical engineering at the University of Wyoming in Laramie.
In the spring of 2020, I reached out to an organization at the University of Wyoming looking for opportunities to further my education in the field of aerospace. They introduced me to the Wyoming Space Grand Consortium and, through their website, I learned of and applied to be a NASA Office of STEM Engagement intern in the spring of 2021. I received an offer and, in the summer of 2021, began working as a remote intern at Goddard on the 3D modeling and rendering of early spacecraft.
How did the Hispanic Advisory Committee for Employees (HACE) introduce you to the Pathways Program?
The summer of 2021, the different employee advisory committees at Goddard held presentations for the interns. I am Hispanic; I naturally gravitated towards HACE and fell in love with the extremely warm community they provided.
I attended their monthly meetings and I presented to the center at their end of the summer intern presentation. HACE introduced me to the Pathways Program, and the organization was instrumental in my becoming a Pathways student intern. This Pathways internship eventually led to my conversion to a fulltime employee and my current position in the Mechanical Engineering Branch here at Goddard.
What one piece of advice would you give to a new intern?
Never be afraid to ask questions and always seek out new connections. Goddard is a well of knowledge, you can learn and grow a lot from those around you.
Tell us about your mentorship at Goddard.
Jack Marshall is an aerospace engineer and the lead for SASS. When I was an intern, he showed me a glimpse into the world of engineering, providing perspective on all aspects of the project from administrative to technical. He continues to guide my engineering journey and has been instrumental in developing me into the engineer I am today. I am incredibly grateful to Jack for his welcome and his guidance.
What is the coolest part about your job?
The best parts about my job are the people I get to work with and the hardware we get to build. Whether we’re in a small lab in Goddard’s integration and testing facility or a large clean room, I get to spend most of my days working with incredible people to build, test, and integrate flight hardware. Every day there is something to be excited about and someone I get to work with who is likely to teach me something new. That excitement makes my work fun.
It’s also fun to work in facilities like the largest clean room at Goddard, where the James Webb Space Telescope was built. It was interesting getting used to being gowned up. You start with removing electronics and putting on a face mask, hair net, and shoe covers, before taking a quick air shower. Next comes the hood, coveralls, and boots, before taping your gloves and finally entering the clean room.
“Whether we’re in a small lab in Goddard’s integration and testing facility or a large clean room, I get to spend most of my days working with incredible people to build, test, and integrate flight hardware,” said Aaron. “Every day there is something to be excited about and someone I get to work with who is likely to teach me something new.”Photo credit: NASA/Jolearra TshiteyaWhat do you hope to be doing in five years?
I would hope to have the opportunity to continue learning and working here at Goddard. I love what I do, and I hope to help others interested, find a similar path to NASA.
What do you do fun?
I still love to go fishing and hiking any chance I get and have been looking forward to doing more here in Maryland. Since moving to the area, I have also been enjoying attending Nationals baseball games in D.C., and I have been looking for opportunities to continuing to play music since graduating college.

Article 2 weeks agoNASA JPL Developing Underwater Robots to Venture Deep Below Polar Ice
Called IceNode, the project envisions a fleet of autonomous robots that would help determine the melt rate of ice shelves.
On a remote patch of the windy, frozen Beaufort Sea north of Alaska, engineers from NASA’s Jet Propulsion Laboratory in Southern California huddled together, peering down a narrow hole in a thick layer of sea ice. Below them, a cylindrical robot gathered test science data in the frigid ocean, connected by a tether to the tripod that had lowered it through the borehole.
This test gave engineers a chance to operate their prototype robot in the Arctic. It was also a step toward the ultimate vision for their project, called IceNode: a fleet of autonomous robots that would venture beneath Antarctic ice shelves to help scientists calculate how rapidly the frozen continent is losing ice — and how fast that melting could cause global sea levels to rise.
Warming Waters, Treacherous TerrainIf melted completely, Antarctica’s ice sheet would raise global sea levels by an estimated 200 feet (60 meters). Its fate represents one of the greatest uncertainties in projections of sea level rise. Just as warming air temperatures cause melting at the surface, ice also melts when in contact with warm ocean water circulating below. To improve computer models predicting sea level rise, scientists need more accurate melt rates, particularly beneath ice shelves — miles-long slabs of floating ice that extend from land. Although they don’t add to sea level rise directly, ice shelves crucially slow the flow of ice sheets toward the ocean.
A remote camera captured an IceNode prototype deployed below the frozen surface of Lake Superior, off Michigan’s Upper Peninsula, during a field test in 2022. The three thin legs of the robot’s “landing gear” affix the prototype to the icy ceiling.NASA/JPL-CaltechThe challenge: The places where scientists want to measure melting are among Earth’s most inaccessible. Specifically, scientists want to target the underwater area known as the “grounding zone,” where floating ice shelves, ocean, and land meet — and to peer deep inside unmapped cavities where ice may be melting the fastest. The treacherous, ever-shifting landscape above is dangerous for humans, and satellites can’t see into these cavities, which are sometimes beneath a mile of ice. IceNode is designed to solve this problem.
“We’ve been pondering how to surmount these technological and logistical challenges for years, and we think we’ve found a way,” said Ian Fenty, a JPL climate scientist and IceNode’s science lead. “The goal is getting data directly at the ice-ocean melting interface, beneath the ice shelf.”
Floating FleetHarnessing their expertise in designing robots for space exploration, IceNode’s engineers are developing vehicles about 8 feet (2.4 meters) long and 10 inches (25 centimeters) in diameter, with three-legged “landing gear” that springs out from one end to attach the robot to the underside of the ice. The robots don’t feature any form of propulsion; instead, they would position themselves autonomously with the help of novel software that uses information from models of ocean currents.
JPL’s IceNode project is designed for one of Earth’s most inaccessible locations: underwater cavities deep beneath Antarctic ice shelves. The goal is getting melt-rate data directly at the ice-ocean interface in areas where ice may be melting the fastest. Credit: NASA/JPL-CaltechReleased from a borehole or a vessel in the open ocean, the robots would ride those currents on a long journey beneath an ice shelf. Upon reaching their targets, the robots would each drop their ballast and rise to affix themselves to the bottom of the ice. Their sensors would measure how fast warm, salty ocean water is circulating up to melt the ice, and how quickly colder, fresher meltwater is sinking.
The IceNode fleet would operate for up to a year, continuously capturing data, including seasonal fluctuations. Then the robots would detach themselves from the ice, drift back to the open ocean, and transmit their data via satellite.
“These robots are a platform to bring science instruments to the hardest-to-reach locations on Earth,” said Paul Glick, a JPL robotics engineer and IceNode’s principal investigator. “It’s meant to be a safe, comparatively low-cost solution to a difficult problem.”
Arctic Field TestWhile there is additional development and testing ahead for IceNode, the work so far has been promising. After previous deployments in California’s Monterey Bay and below the frozen winter surface of Lake Superior, the Beaufort Sea trip in March 2024 offered the first polar test. Air temperatures of minus 50 degrees Fahrenheit (minus 45 Celsius) challenged humans and robotic hardware alike.
The test was conducted through the U.S. Navy Arctic Submarine Laboratory’s biennial Ice Camp, a three-week operation that provides researchers a temporary base camp from which to conduct field work in the Arctic environment.
As the prototype descended about 330 feet (100 meters) into the ocean, its instruments gathered salinity, temperature, and flow data. The team also conducted tests to determine adjustments needed to take the robot off-tether in future.
“We’re happy with the progress. The hope is to continue developing prototypes, get them back up to the Arctic for future tests below the sea ice, and eventually see the full fleet deployed underneath Antarctic ice shelves,” Glick said. “This is valuable data that scientists need. Anything that gets us closer to accomplishing that goal is exciting.”
IceNode has been funded through JPL’s internal research and technology development program and its Earth Science and Technology Directorate. JPL is managed for NASA by Caltech in Pasadena, California.

NASA’s Roman Space Telescope to Investigate Galactic Fossils
NASA, Ralf Crawford (STScI)
The universe is a dynamic, ever-changing place where galaxies are dancing, merging together, and shifting appearance. Unfortunately, because these changes take millions or billions of years, telescopes can only provide snapshots, squeezed into a human lifetime.
However, galaxies leave behind clues to their history and how they came to be. NASA’s upcoming Nancy Grace Roman Space Telescope will have the capacity to look for these fossils of galaxy formation with high-resolution imaging of galaxies in the nearby universe.
Astronomers, through a grant from NASA, are designing a set of possible observations called RINGS (the Roman Infrared Nearby Galaxies Survey) that would collect these remarkable images, and the team is producing publicly available tools that the astronomy community can use once Roman launches and starts taking data. The RINGS survey is a preliminary concept that may or may not be implemented during Roman’s science mission.
Roman is uniquely prepared for RINGS due to its resolution akin to NASA’s Hubble Space Telescope and its wide field of view – – 200 times that of Hubble in the infrared – – making it a sky survey telescope that complements Hubble’s narrow-field capabilities.
Galactic ArchaeologistsScientists can only look at brief instances in the lives of evolving galaxies that eventually lead to the fully formed galaxies around us today. As a result, galaxy formation can be difficult to track.
Luckily, galaxies leave behind hints of their evolution in their stellar structures, almost like how organisms on Earth can leave behind imprints in rock. These galactic “fossils” are groups of ancient stars that hold the history of the galaxy’s formation and evolution, including the chemistry of the galaxy when those stars formed.
These cosmic fossils are of particular interest to Robyn Sanderson, the deputy principal investigator of RINGS at the University of Pennsylvania in Philadelphia. She describes the process of analyzing stellar structures in galaxies as “like going through an excavation and trying to sort out bones and put them back together.”
Roman’s high resolution will allow scientists to pick out these galactic fossils, using structures ranging from long tidal tails on a galaxy’s outskirts to stellar streams within the galaxy. These large-scale structures, which Roman is uniquely capable of capturing, can give clues to a galaxy’s merger history. The goal, says Sanderson, is to “reassemble these fossils in order to look back in time and understand how these galaxies came to be.”
Shedding Light on Dark MatterRINGS will also enable further investigations of one of the most mysterious substances in the universe: dark matter, an invisible form of matter that makes up most of a galaxy’s mass. A particularly useful class of objects for testing dark matter theories are ultra-faint dwarf galaxies. According to Raja GuhaThakurta of the University of California, Santa Cruz, “Ultra faint dwarf galaxies are so dark matter-dominated that they have very little normal matter for star formation. With so few stars being created, ultra-faint galaxies can essentially be seen as pure blobs of dark matter to study.”
Roman, thanks to its large field of view and high resolution, will observe these ultra-faint galaxies to help test multiple theories of dark matter. With these new data, the astronomical community will come closer to finding the truth about this unobservable dark matter that vastly outweighs visible matter: dark matter makes up about 80% of the universe’s matter while normal matter comprises the remaining 20%.
Ultra-faint galaxies are far from the only test of dark matter. Often, just looking in an average-sized galaxy’s backyard is enough. Structures in the halo of stars surrounding a galaxy often give hints to the amount of dark matter present. However, due to the sheer size of galactic halos (they are often 15-20 times as big as the galaxy itself), current telescopes are deeply inefficient at observing them.
At the moment, the only fully resolved galactic halos scientists have to go on are our own Milky Way and Andromeda, our neighbor galaxy. Ben Williams, the principal investigator of RINGS at the University of Washington in Seattle, describes how Roman’s power will amend this problem: “We only have reliable measurements of the Milky Way and Andromeda, because those are close enough that we can get measurements of a large number of stars distributed across their stellar halos. So, with Roman, all of a sudden we’ll have 100 or more of these fully resolved galaxies.”
When Roman launches by May 2027, it is expected to fundamentally alter how scientists understand galaxies. In the process, it will shed some light on our own home galaxy. The Milky Way is easy to study up close, but we do not have a large enough selfie stick to take a photo of our entire galaxy and its surrounding halo. RINGS shows what Roman is capable of should such a survey be approved. By studying the nearby universe, RINGS can examine galaxies similar in size and age to the Milky Way, and shed light on how we came to be here.
The Nancy Grace Roman Space Telescope is managed at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, with participation by NASA’s Jet Propulsion Laboratory and Caltech/IPAC in Southern California, the Space Telescope Science Institute in Baltimore, and a science team comprising scientists from various research institutions. The primary industrial partners are BAE Systems, Inc in Boulder, Colorado; L3Harris Technologies in Rochester, New York; and Teledyne Scientific & Imaging in Thousand Oaks, California.

Hubble Observes An Oddly Organized Satellite NASA, ESA, and E. Skillman (University of Minnesota – Twin Cities; Processing: Gladys Kober (NASA/Catholic University of America)Andromeda III is one of at least 13 dwarf satellite galaxies in orbit around the Andromeda galaxy, or Messier 31, the Milky Way’s closest grand spiral galactic neighbor. Andromeda III is a faint, spheroidal collection of old, reddish stars that appears devoid of new star formation and younger stars. In fact, Andromeda III seems to be only about 3 billion years younger than the majority of globular clusters ― dense knots of stars thought to have been mostly born at the same time, which contain some of the oldest stars known in the universe.
Astronomers suspect that dwarf spheroidal galaxies may be leftovers of the kind of cosmic objects that were shredded and melded by gravitational interactions to build the halos of large galaxies. Curiously, studies have found that several of the Andromeda Galaxy’s dwarf galaxies, including Andromeda III, orbit in a flat plane around the galaxy, like the planets in our solar system orbit around the Sun. The alignment is puzzling because models of galaxy formation don’t show dwarf galaxies falling into such orderly formations, but rather moving around the galaxy randomly in all directions. As they slowly lose energy, the dwarf galaxies merge into the larger galaxy.
The odd alignment could be because many of Andromeda’s dwarf galaxies fell into orbit around it as a single group, or because the dwarf galaxies are scraps left over from the merger of two larger galaxies. Either of these theories, which are being researched via NASA’s James Webb Space Telescope, would complicate theories of galaxy formation but also help guide and refine future models.
NASA’s Hubble Space Telescope took this image of Andromeda III as part of an investigation into the star formation and chemical enrichment histories of a sample of M31 dwarf spheroidal galaxies that compared their first episodes of star formation to those of Milky Way satellite galaxies.

Sols 4289-4290: From Discovery Pinnacle to Kings Canyon and Back Again This image shows the workspace in front of NASA’s Mars rover Curiosity, taken by the Left Navigation Camera aboard the rover on sol 4287 — Martian day 4,287 of the Mars Science Laboratory mission — on Aug. 28, 2024, at 02:23:27 UTC. NASA/JPL-CaltechEarth planning date: Wednesday, Aug. 28 2024
We are back … almost, anyways. Today’s parking location is very close to where we parked on sol 4253, and in an area near one of the previous contact science targets “Discovery Pinnacle.” You can read in this blog post that most of the team, this blogger included, was in Pasadena for our team meeting when we were last in this area. That was July and Curiosity was about to turn 12 on Mars. Coming back is a very rare occasion and is always planned carefully. Once or twice during the last 12 years it happened because we saw something “in the rear mirror.” One of the examples is the target “Old Soaker,” where we spotted mud cracks in the images from a previous parking position, and promptly went back because this was such an important discovery. At other times it was carefully planned, such as the “walkabout” at “Pink Cliffs,” which you can watch in this video from as long back as Earth year 2015. In the past few planning cycles, it’s more of the latter as we made our way from Discovery Pinnacle, where we were on sol 4253, “Just passing through” “Russell Pass” and arriving at “Kings Canyon,” our drill location, which we reached on sol 4257. You can follow all the action of the drilling at Kings Canyon on the blogs. It took a while — it always does — because it’s an activity with many steps and investigations to complete. We actually celebrated Curiosity’s 12th birthday at Kings Canyon! We departed on sol 4283, came back via “Cathedral Peak,” and are now near the Discovery Pinnacle location again. After that little walkabout through the history of (some) of Curiosity’s walkabouts, especially the very last one, let’s look at today’s plan.
It is a pretty normal two-sol plan, with a one-hour science block before we drive away from this location. We were greeted by a nicely flat surface, and the engineers informed us that we have all six wheels firmly on flat and stable ground. That’s always a relief, because only then can we use the arm. That nice piece of flat rock Curiosity is so firmly parked on became our science target …well, mostly. Some of the little pebbles on the surface attracted our attention, too. The very eagle-eyed can spot a small white spot in the image above. It’s right between the arm and the rover itself, about where the C is written. That’s a rock that we likely broke up with our wheel and that has a very white part to it. We called it “Thousand Island Lake,” and will image it with MAHLI. APXS is investigating a target called “Eichorn Pinnacle,” squarely on the big flat area. LIBS is also making the most of the large target underneath and in front of us, investigating the target “Nine Lakes Basin.”
In recent blogs you will have read about the dust-storm watch making the atmospheric investigations even more important, so we don’t miss any changes. We are looking for dust devils, atmospheric opacity, and are of course monitoring the weather throughout the plan.
Our drive will hopefully — if Mars agrees — be a long one, and we will also plan an activity that we call MARDI sidewalk. That’s when we take very frequent pictures with the MARDI instrument while driving. This results in a long strip of images nicely showing the nature of the terrain the rover has driven over. This is in addition to the MARDI single frame we are taking every time the rover stops. I often get the question, why are we taking an image just downwards whenever the rover stops? Well, humans are easy to bias toward the outliers, toward the things that look special, and of course the Curiosity team is no exception. For some things this is great, because it allows for the discoveries of new things. But it doesn’t provide an unbiased overview. That’s what MARDI does: It always points down and reliably records the terrain under the rover. We don’t have to do anything but put the commands for that one image into our plan after the drive — something that’s pretty routine after 12 years now!

Several certification standards/guidelines now recommend and/or mandate the development of assurance cases for software-intensive systems, e.g., defense (UK MoD DS-0056), aviation (CAP 760, FAA’s operational approval guidance for unmanned aircraft systems), automotive (ISO 26262), and healthcare (FDA infusion pumps total product lifecycle guidance). As such, there is a need to develop models, techniques and tools that target the development of assurance arguments for software.
The goals of the 2016 Workshop on Assurance Cases for Software-intensive Systems (ASSURE 2016) are to:
- explore techniques for creating/assessing assurance cases for software-intensive systems;
- examine the role of assurance cases in the engineering lifecycle of critical systems;
- identify the dimensions of effective practice in the development and evaluation of assurance cases;
- investigate the relationship between dependability techniques and assurance cases; and,
- identify critical research challenges and define a roadmap for future development.
We solicit high-quality contributions: research, practice, tools and position papers on the application of assurance case principles and techniques to assure that the dependability properties of critical software-intensive systems have been met.
Papers should attempt to address the workshop goals in general.
TopicsTopics of interest include, but are not limited to:
- Assurance issues in emerging paradigms, e.g., adaptive and autonomous systems, including self-driving cars, unmanned aircraft systems, complex health care and decision making systems, etc.
- Standards: Industry guidelines and standards are increasingly requiring the development of assurance cases, e.g., the automotive standard ISO 26262 and the FDA guidance on the total product lifecycle for infusion pumps.
- Certification and Regulations: The role and usage of assurance cases in the certification of critical systems, as well as to show compliance to regulations.
- Dependable architectures: How do fault-tolerant architectures and design measures such as diversity and partitioning relate to assurance cases?
- Dependability analysis: What are the relationships between dependability analysis techniques and the assurance case paradigm?
- Tools: Using the output from software engineering tools (testing, formal verification, code generators) as evidence in assurance cases / using tools for the modeling, analysis and management of assurance cases.
- Application of formal techniques to create and analyze arguments.
- Exploration of relevant techniques for assurance cases for real-time, concurrent, and distributed systems.
- Modeling and Metamodeling: Representation of structured arguments through meta models, such as OMG’s Structured Assurance Case Metamodel (SACM).
- Assurance of software quality attributes, e.g., safety, security and maintainability, as well as dependability in general, including tradeoffs, and exploring notions of the quality of assurance cases themselves.
- Domain-specific assurance issues, in domains such as aerospace, automotive, healthcare, defense and power.
- Reuse and Modularization: Contracts and patterns for improving the reuse of assurance case structures.
- Connections between the Goal Structuring Notation for assurance cases, and goal-orientation from the requirements engineering community.

As such, there is a need to develop models, techniques and tools that target the development of assurance arguments for software.
The goals of the 2015 Workshop on Assurance Cases for Software-intensive Systems (ASSURE 2015) are to:
- explore techniques for creating/assessing assurance cases for software-intensive systems;
- examine the role of assurance cases in the engineering lifecycle of critical systems;
- identify the dimensions of effective practice in the development and evaluation of assurance cases;
- investigate the relationship between dependability techniques and assurance cases; and,
- identify critical research challenges and define a roadmap for future development.
We solicit high-quality contributions: research, practice, tools and position papers on the application of assurance case principles and techniques to assure that the dependability properties of critical software-intensive systems have been met.
Papers should attempt to address the workshop goals in general.
Topics
Topics of interest include, but are not limited to:
- Standards: Industry guidelines and standards are increasingly requiring the development of assurance cases, e.g., the automotive standard ISO 26262 and the FDA guidance on the total product lifecycle for infusion pumps.
- Certification and Regulations: The role and usage of assurance cases in the certification of critical systems, as well as to show compliance to regulations.
- Dependable architectures: How do fault-tolerant architectures and design measures such as diversity and partitioning relate to assurance cases?
- Dependability analysis: What are the relationships between dependability analysis techniques and the assurance case paradigm?
- Tools: Using the output from software engineering tools (testing, formal verification, code generators) as evidence in assurance cases / using tools for the modeling, analysis and management of assurance cases.

The Marshall Star for August 28, 2024
By Wayne Smith
Leadership from NASA’s Marshall Space Flight Center highlighted a successful summer before looking ahead to the center’s culture and strategy during an all-hands meeting Aug. 27 in Building 4316.
Marshall Director Joseph Pelfrey recapped milestone events of the past few months, including new hardware for the Artemis II test flight. The launch vehicle stage adapter for the SLS (Space Launch System) rocket was rolled out Aug. 21 at Marshall and loaded on to the Pegasus barge. In July, the rocket’s core stage was shipped from NASA’s Michoud Assembly Facility to the agency’s Kennedy Space Center. The summer started with a NASA in the Park event in downtown Huntsville that attracted more than 14,000 people to learn more about Marshall’s work and is winding down with the continued celebration of the 25th anniversary of NASA’s Chandra X-ray Observatory.
NASA Marshall Space Flight Center Director Joseph Pelfrey, left, speaks to team members during the all-hands meeting Aug. 26 in Building 4316. Joining Pelfrey on stage, from left, are Rae Ann Meyer, deputy director; Roger Baird, associate director; and Larry Leopard, associate director, technical. NASA/Krisdon ManeckePelfrey also commended Marshall’s Commercial Crew Program team members for their dedicated work and support of NASA’s Boeing Starliner Crew Flight Test to the International Space Station.
“I just really appreciate the teams that worked so hard between NASA and Boeing to evaluate issues, and the ultimate decision was about safety,” Pelfrey said. “Those teams did a lot of tremendous work on analysis and testing to bring data to decision makers. Now we will get to move forward.”
Before discussing Marshall’s culture and strategy, Pelfrey introduced three new members of Marshall’s leadership team: Davey Jones, center strategy lead; Denise Smithers, center executive officer; and Roger Baird, associate director.
Pelfrey said leadership recognizes the vital roles culture and strategy play in the center’s ongoing success as Marshall makes a transformative shift to more strategic partnerships across NASA and with industry. He pointed to activities like NASA 2040 and More to Marshall as the center heads toward its 65th anniversary next summer.
“Embracing a supportive work culture enhances collaboration, improves communication, and builds a sense of belonging and purpose,” Pelfrey said. “The center’s leadership team wants culture to come from all of us, so we continue to create opportunities for you to get involved, hear your feedback, and help shape the culture at Marshall.”
Rae Ann Meyer, the center’s deputy director, provided updates on Marshall’s culture initiatives. She invited team members to participate in a survey on the most important attributes for a thriving center, following up on feedback from last August. Meyer said leadership wants continued input from team members and applauded Marshall’s highest ever participation (85.1%) in the 2024 Federal Employee Viewpoint Survey.
Marshall team members listen as Meyer, on stage at left, talks about the center’s culture initiatives.NASA/Krisdon Manecke“Regardless of role, each team member plays a vital part in shaping the culture that makes NASA and Marshall an extraordinary place to work and achieve great things,” Meyer said. “Creating a positive culture is a long-term process that requires time and sustained effort – it does not happen overnight.”
In his remarks, Jones also encouraged feedback and participation from team members. He said center culture and strategy “need to be attached at the hip.”
“Part of that success is making sure communication is open between center strategy and culture and to the workforce because it not only encourages collaboration, but also fosters transparency, which is one of the key cultural attributes discussed today,” Jones said.
Leadership took questions from team members to close out the session, before wrapping up with a More to Marshall video.
“This year, you have heard a lot about More to Marshall, and it is more than a slogan; it really symbolizes the initiative we have to prepare our center for the future and take advantage of all the expertise we have at the center and all our capabilities,” Pelfrey said. “It’s an approach that reinforces our center strategy that’s going to enable our future role in space exploration.”

NASA Moves Artemis II Rocket Adapter to Pegasus Barge for ShipmentNASA rolled out a key piece of space flight hardware for the SLS (Space Launch System) rocket for the first crewed mission of NASA’s Artemis campaign from Marshall Space Flight Center on Aug. 21 for shipment to the agency’s Kennedy Space Center. The cone-shaped launch vehicle stage adapter connects the rocket’s core stage to the upper stage and helps protect the upper stage’s engine that will help propel the Artemis II test flight around the Moon, slated for 2025.
Crews moved the cone-shaped launch vehicle stage adapter out of Building 4708 at NASA’s Marshall Space Flight Center to the agency’s Pegasus barge on Aug. 21. The barge will ferry the adapter first to NASA’s Michoud Assembly Facility, where it will pick up additional SLS hardware for future Artemis missions, and then travel to the agency’s Kennedy Space Center. In Florida, teams with NASA’s Exploration Ground Systems will prepare the adapter for stacking and launch.NASA/Brandon Hancock“The launch vehicle stage adapter is the largest SLS component for Artemis II that is made at the center,” said Chris Calfee, SLS Spacecraft Payload Integration and Evolution element manager. “Both the adapters for the SLS rocket that will power the Artemis II and Artemis III missions are fully produced at NASA Marshall. Alabama plays a key role in returning astronauts to the Moon.”

(NASA) Cassiopeia A,Thenthe Cosmos: 25 Years of Chandra X-ray ScienceBy Rick Smith
On Aug. 26, 1999, NASA’s Chandra X-ray Observatory opened its powerful telescopic eye in orbit and captured its awe-inspiring “first light” images of Cassiopeia A, a supernova remnant roughly 11,000 light-years from Earth. That first observation was far more detailed than anything seen by previous X-ray telescopes, even revealing – for the first time ever – a neutron star left in the wake of the colossal stellar detonation.
NASA’s Chandra X-ray Observatory has observed Cassiopeia A for more than 2 million total seconds since its “first light” images of the supernova remnant on Aug. 26, 1999. Cas A is some 11,000 light-years from Earth. Chandra X-rays are depicted in blue and composited with infrared images from NASA’s James Webb Space Telescope in orange and white.X-ray: NASA/CXC/SAO; Infrared: NASA/ESA/CSA/STScI/D. Milisavljevic (Purdue Univ.), I. De Looze (University of Ghent), T. Temim (Princeton Univ.); Image Processing: NASA/CXC/SAO/J. Schmidt, K. Arcand, and J. MajorThose revelations came as no surprise to Chandra project scientist Martin Weisskopf, who led Chandra’s development at NASA’s Marshall Space Flight Center. “When you build instrumentation that’s 10 times more sensitive than anything that was done before, you’re bound to discover something new and exciting,” he said. “Every step forward was a giant step forward.”
Twenty-five years later, Chandra has repeated that seminal moment of discovery again and again, delivering – to date – nearly 25,000 detailed observations of neutron stars, quasars, supernova remnants, black holes, galaxy clusters, and other highly energetic objects and events, some as far away as 13 billion light-years from Earth.
Chandra has further helped scientists gain tangible evidence of dark matter and dark energy, documented the first electromagnetic events tied to gravitational waves in space, and most recently aided the search for habitable exoplanets – all vital tools for understanding the vast, interrelated mechanisms of the universe we live in.
“Chandra’s first image of Cas A provided stunning demonstration of Chandra’s exquisite X-ray mirrors, but it simultaneously revealed things we had not known about young supernova remnants,” said Pat Slane, director of the CXC (Chandra X-ray Center) housed at the Smithsonian Astrophysical Observatory in Cambridge, Massachusetts. “In a blink, Chandra not only revealed the neutron star in Cas A; it also taught us that young neutron stars can be significantly more modest in their output than what previously had been understood. Throughout its 25 years in space, Chandra has deepened our understanding of fundamental astrophysics, while also greatly broadening our view of the universe.”
To mark Chandra’s silver anniversary, NASA and CXC have shared 25 of its most breathtaking images and debuted a new video, “Eye on the Cosmos.”
Chandra often is used in conjunction with other space telescopes that observe the cosmos in different parts of the electromagnetic spectrum, and with other high-energy missions such as ESA’s (European Space Agency’s) XMM-Newton; NASA’s Swift, NuSTAR (Nuclear Spectroscopic Telescope Array), and IXPE (Imaging X-ray Polarization Explorer) imagers, and NASA’s NICER (Neutron Star Interior Composition Explorer) X-ray observatory, which studies high-energy phenomena from its vantage point aboard the International Space Station.
These images were released to commemorate the 25th anniversary of Chandra. They represent the wide range of objects that the telescope has observed over its quarter century of observations. X-rays are an especially penetrating type of light that reveals extremely hot objects and very energetic physical processes. The images range from supernova remnants, like Cassiopeia A, to star-formation regions like the Orion Nebula, to the region at the center of the Milky Way. This montage also contains objects beyond our own Galaxy including other galaxies and galaxy clusters.X-ray: NASA/CXC/UMass/Q.D. Wang; Image processing: NASA/CXC/SAO/N. WolkChandra remains a unique, global science resource, with a robust data archive that will continue to serve the science community for many years.
“NASA’s project science team has always strived to conduct Chandra science as equitably as possible by having the world science community collectively decide how best to use the observatory’s many tremendous capabilities,” said Douglas Swartz, a USRA (Universities Space Research Association) principal research scientist on the Chandra project science team.
“Chandra will continue to serve the astrophysics community long after its mission ends,” said Andrew Schnell, acting Chandra program manager at Marshall. “Perhaps its greatest discovery hasn’t been discovered yet. It’s just sitting there in our data archive, waiting for someone to ask the right question and use the data to answer it. It could be somebody who hasn’t even been born yet.”
That archive is impressive indeed. To date, Chandra has delivered more than 70 trillion bytes of raw data. More than 5,000 unique principal investigators and some 3,500 undergraduate and graduate students around the world have conducted research based on Chandra’s observations. Its findings have helped earn more than 700 PhDs and resulted in more than 11,000 published papers, with half a million total citations.
NASA’s Chandra X-ray Observatory data, seen here in violet and white, is joined with that of NASA’s Hubble Space Telescope (red, green, and blue) and Imaging X-ray Polarimetry Explorer (purple) to show off the eerie beauty of the Crab Nebula. The nebula is the result of a bright supernova explosion first witnessed and documented in 1054 A.D.X-ray: (Chandra) NASA/CXC/SAO, (IXPE) NASA/MSFC; Optical: NASA/ESA/STScI; Image Processing: NASA/CXC/SAO/J. Schmidt, K. Arcand, and L. FrattareWeisskopf is now an emeritus researcher who still keeps office hours every weekday despite having retired from NASA in 2022. He said the work remains as stimulating now as it was 25 years ago, waiting breathlessly for those “first light” images.
“We’re always trying to put ourselves out of business with the next bit of scientific understanding,” he said. “But these amazing discoveries have demonstrated how much NASA’s astrophysics missions still have to teach us.”
The universe keeps turning – and Chandra’s watchful eye endures.
Chandra, managed for NASA by Marshall in partnership with the CXC, is one of NASA’s Great Observatories, along with the Hubble Space Telescope and the now-retired Spitzer Space Telescope and Compton Gamma Ray Observatory. It was first proposed to NASA in 1976 by Riccardo Giacconi, recipient of the 2002 Nobel Prize for Physics based on his contributions to X-ray astronomy, and Harvey Tananbaum, who would later become the first director of the Chandra X-ray Center. Chandra was named in honor of the late Nobel laureate Subrahmanyan Chandrasekhar, who earned the Nobel Prize in Physics in 1983 for his work explaining the structure and evolution of stars.

Take 5 with April HargraveBy Wayne Smith
April Hargrave’s father was an educator who encouraged her from an early age to believe she could be whatever she wanted to be.
She followed her father’s guidance.
April Hargrave is the manager of Program, Planning, and Control (PP&C) in the Human Exploration Development and Operations (HP/HEDO) Office at NASA’s Marshall Space Flight Center.Photo courtesy of Jenna HassellToday, Hargrave is the manager of Program, Planning, and Control (PP&C) in the Human Exploration Development and Operations (HP/HEDO) Office at NASA’s Marshall Space Flight Center. Hargrave credits her parents for inspiring her to seek a career that eventually led to Marshall, where she has been for 15 years.
Hargrave’s father – G.W. Braidfoot – was a high school educator in Lawrence County, Alabama, for 28 years. He taught history and civics, before moving into roles as an administrator and guidance counselor, focusing on guiding his students toward their post-high school goals.
“What has always stood out to me is my parents never placed boundaries on my passions and career choices,” said Hargrave, a North Alabama native who lives in Athens. “Reflecting back, that is something of which I am very appreciative. In the absence of boundaries, it has allowed me to push myself in my pursuits and shaped my career path, which included high school STEM courses and college career choices.
Those college choices were pursuing a bachelor’s degree in chemistry at the University of North Alabama in Florence, and later another degree in chemical engineering at the University of Alabama in Huntsville.
As PP&C manager for HEDO’s diverse and complex portfolio of programs, projects, and other activities, Hargrave provides tools and resources to HP management that enables strategic decision making and workforce planning.
“My background and experiences helped shaped my early career in industry and established a strong foundation and relationships, which led me to Marshall mid-career,” she said. “At Marshall, I’m thankful to have had mentors and encouragers who have led me to my current leadership role – people who believed in me and allowed me an opportunity. For that, I will forever be grateful.”
Question: What excites you most about the future of human space exploration, or your NASA work, and your team’s role it?
Hargrave: What excites me the most are the advancements we are making in human health and exploration. I’ve had close relatives suffer from diseases, such as Alzheimer’s and heart disease. I hope to see in the near future outcomes of human research on the International Space Station and the Moon that leads to medical and technology advancements, resulting in slowing the progression and eventually eliminating these diseases. Our HP PP&C team enables our missions by providing planning, integration, and support across our organization.
Question: What has been the proudest moment of your career and why?
Hargrave: Being able to mentor others throughout my career and watching them achieve success. Being in a position to recognize potential in others and encourage them to stretch and take risks in their careers, I find it very rewarding, especially after they have moved on that I’m able to still observe the growth and development they’ve experienced and to know I made a contribution.
Question: Who or what drives/motivates you?
Hargrave: My team drives me – I have a wonderful team that motivates me to be the best version of myself I can be. My team is comprised of a diverse group of personnel whose jobs are not always connected. However, we are still able to promote a great teaming environment where we encourage and leverage off each other’s skills and knowledge bases. My team is dedicated to doing the best job possible which motivates me daily in the excellent support they provide across HP. It allows me opportunities to lead by example and recognize their successes. It also allows me to look across the team and how to use them best based on their strengths.
Question: What advice do you have for employees early in their NASA career or those in new leadership roles?
Hargrave: It is important to learn what the NASA mission is and don’t be afraid to ask questions. Learn about the work that you are doing and how it impacts the mission as a whole. As you learn and understand the work within your role, develop a passion for the work. Take opportunities to understand the big picture and learn what others are doing across the center. Don’t be afraid to take lateral opportunities to allow you to gain new experiences and broaden your knowledge base. And if you find yourself in a leadership role, never lose sight that it’s the people behind that work that’s most important. Take the time to build and nurture those relationships because at the end of the day, our workforce is what makes us successful.
Question: What do you enjoy doing with your time while away from work?
Hargrave: My joy is helping and supporting others. Being part of a large family (raised one of five children and an even larger extended family), there’s naturally always plenty to do and lots of family to help and encourage. Much of my recent years have been spent cheering on my sons, nieces, and nephews. I also enjoy serving in my church and helping organize events to celebrate our family and friends.

Over the Moon: Photographer Captures Supermoon Rising Near MarshallBy Wayne Smith
Once in a Blue Moon wasn’t enough for Michael DeMocker, a photographer for NASA’s Michoud Assembly Facility.
Nearly one year after capturing a spectacular image of a super Blue Moon rising over the Crescent City Connection Bridge in New Orleans, DeMocker found another opportunity to focus his camera on the lunar landscape while visiting the Rocket City. The result was another stunning photograph, this one of the Moon rising Aug. 19 behind the Saturn V rocket at the U.S. Space & Rocket Center in Huntsville, near NASA’s Marshall Space Flight Center
A super Blue Moon rises Aug. 19 over Huntsville, home to NASA’s Marshall Space Flight Center and the U.S. Space and Rocket Center. The full Moon was both a supermoon and a Blue Moon. As the Moon reaches its closest approach to Earth, the Moon looks larger in the night sky with supermoons becoming the biggest and brightest full Moons of the year. While not blue in color, the third full Moon in a season with four full Moons is called a Blue Moon.NASA/Michael DeMockerAnd you can say the image DeMocker captured left him, well, over the Moon. He explains how he got the photo.
“NASA photographer Eric Bordelon and I drove up from Michoud to Marshall to provide drone support for the move of the launch vehicle stage adapter of the SLS (Space Launch System) rocket to NASA’s Pegasus barge on Aug. 21,” DeMocker said. “On the trip up, we talked about possibly capturing the super Blue Moon rising that night. Using an app that shows the direction of the moonrise overlayed with a satellite image of the area, we couldn’t find a definitive spot where we thought we could get a clean line of the Moon rising with some kind of iconic Huntsville landmark. So, like good New Orleanians, we put off thinking about it until after eating. As we approached the restaurant, we caught glimpses of the Saturn V rocket at the U.S. Space & Rocket Center. We realized if we got on the roof of a nearby parking garage, we would have a clean view of the Moon rising somewhat behind it.
“The angle wasn’t perfect; I’d have preferred to be more to the right but that would have sent me plummeting off the parking garage. The clouds cooperated, the Moon rose bright and beautiful, and I got images I was happy with while Eric got a very cool time-lapse video of the Moon and the rocket.”
So, of the two Blue Moon images, which is DeMocker’s favorite?
“Yikes, that’s like choosing a child!” DeMocker said. “My favorite pictures are not always the best ones, but the ones that I didn’t think I would be able to pull off. So, while the Moon over the bridge I think is an overall better photo, it was pretty easy to plan and didn’t require much resourcefulness, so I like the rocket one better.”
DeMocker, a past Pulitzer Prize winner for team coverage of Hurricane Katrina, was honored this year with third-place finishes in two categories in NASA’s Photographer of the Year competition. He also was part of a Michoud team that captured a first-place award in the agency’s Videographer of the Year competition.
“But my favorite photos I’ve ever shot in my career have never won awards,” DeMocker said. “I like them because I thought they would be almost impossible to get when I set out after them: a drone shot of an erupting volcano in Iceland, an Iraqi woman voting in Baghdad, or my toddler quietly looking at art in the Louvre.”

NASA, Boeing Optimizing Vehicle Assembly Building High Bay for Future SLS Stage ProductionNASA is preparing space at the agency’s Kennedy Space Center for upcoming assembly activities of the SLS (Space Launch System) rocket core stage for future Artemis missions, beginning with Artemis III.
Teams are currently outfitting the assembly building’s High Bay 2 for future vertical assembly of the rocket stage that will help power NASA’s Artemis campaign to the Moon. During Apollo, High Bay 2, one of four high bays inside the Vehicle Assembly Building, was used to stack the Saturn V rocket. During the Space Shuttle Program, the high bay was used for external tank checkout and storage and as a contingency storage area for the shuttle.
Technicians are building tooling in High Bay 2 at NASA Kennedy that will allow NASA and Boeing, the SLS core stage lead contractor, to vertically integrate the core stage.NASAMichigan-based Futuramic is constructing the tooling that will hold the core stage in a vertical position, allowing NASA and Boeing, the SLS core stage lead contractor, to integrate the SLS rocket’s engine section and four RS-25 engines to finish assembly of the rocket stage. Vertical integration will streamline final production efforts, offering technicians 360-degree access to the stage both internally and externally.
“The High Bay 2 area at NASA Kennedy is critical for work as SLS transitions from a developmental to operational model,” said Chad Bryant, deputy manager of the SLS Stages Office. “While teams are stacking and preparing the SLS rocket for launch of one Artemis mission, the SLS core stage for another Artemis mission will be taking shape just across the aisleway.”
Under the new assembly model beginning with Artemis III, all the major structures for the SLS core stage will continue to be fully produced and manufactured at NASA’s Michoud Assembly Facility. Upon completion of manufacturing and thermal protection system application, the engine section will be shipped to NASA Kennedy for final outfitting. Later, the top sections of the core stage – the forward skirt, intertank, liquid oxygen tank, and liquid hydrogen tank – will be outfitted and joined at Michoud and shipped to Kennedy for final assembly.
The fully assembled core stage for Artemis II arrived at Kennedy on July 23. NASA’s Pegasus barge delivered the SLS engine section for Artemis III to Kennedy in December 2022. Teams at Michoud are outfitting the remaining core stage elements and preparing to horizontally join them. The four RS-25 engines for the Artemis III mission are complete at NASA’s Stennis Space Center and will be transported to Kennedy in 2025. Major core stage and exploration upper stage structures are in work at Michoud for Artemis IV and beyond.
NASA is working to land the first woman, first person of color, and its first international partner astronaut on the Moon under Artemis. SLS is part of NASA’s backbone for deep space exploration, along with the Orion spacecraft, supporting ground systems, advanced spacesuits and rovers, the Gateway in orbit around the Moon, and commercial human landing systems. SLS is the only rocket that can send Orion, astronauts, and supplies to the Moon in a single launch.
NASA’s Marshall Space Flight Center manages the SLS Program and Michoud.
How Students Learn to Fly NASA’s IXPE SpacecraftThe large wall monitor displaying a countdown shows 17 seconds when Amelia “Mia” De Herrera-Schnering tells her teammates “We have AOS,” meaning “acquisition of signal.”
“Copy that, thank you,” Alexander Pichler replies. The two are now in contact with NASA’s IXPE (Imaging X-Ray Polarimeter Explorer) spacecraft, transmitting science data from IXPE to a ground station and making sure the download goes smoothly. That data will then go to the science team for further analysis.
Amelia “Mia” De Herrera-Schnering is an undergraduate student at the University of Colorado, Boulder, and command controller for NASA’s IXPE mission at the Laboratory for Atmospheric and Space Physics (LASP). NASA/Elizabeth LandauAt LASP, the Laboratory for Atmospheric and Space Physics, students at the University of Colorado, Boulder, can train to become command controllers, working directly with spacecraft on pointing the satellites, calibrating instruments, and collecting data. De Herrera-Schnering recently completed her sophomore year, while Pichler had trained as a student and now, having graduated, works as a full-time professional at LASP.
“The students are a key part in what we do,” said Stephanie Ruswick, IXPE flight director at LASP. “We professionals monitor the health and safety of the spacecraft, but so do the students, and they do a lot of analysis for us.”
Students also put into motion IXPE’s instrument activity plans, which are provided by the Science Operations Center at NASA’s Marshall Space Flight Center. The LASP student team schedules contacts with ground stations to downlink data, schedules observations of scientific and calibration targets, and generates the files necessary to translate the scientific operations into spacecraft actions. If IXPE experiences an anomaly, the LASP team will implement plans to remediate and resume normal operations as soon as possible.
The students take part in IXPE’s exploration of a wide variety of celestial targets. In October, for example, students monitored the transmission of data from IXPE’s observations of Swift J1727.8-1613, a bright black hole X-ray binary system. This cosmic object had been recently discovered in September 2023, when NASA’s Neil Gehrels Swift Observatory detected a gamma-ray burst. IXPE’s specialized instruments allow scientists to measure the polarization of X-rays, which contains information about the source of the X-rays as well as the organization of surrounding magnetic fields. IXPE’s follow-up of the Swift object exemplifies how multiple space missions often combine their individual strengths to paint a fuller scientific picture of distant phenomena.
Team members also conduct individual projects. For example, students analyzed how IXPE would fare during both the annular eclipse on Oct. 14, 2023, and the total eclipse that moved across North America on April 8, to make sure that the spacecraft would have adequate power while the Moon partially blocked the Sun.

In the background are flight controllers Adrienne Pickerill, left, and Alexander Pichler, who also trained as students. NASA/Elizabeth LandauWhile most of the students working on IXPE at LASP are engineering majors, some are physics or astrophysics majors. Some didn’t initially start their careers in STEM such as flight controller Kacie Davis, who previously studied art.
Prospective command controllers go through a rigorous 12-week summer training program working 40 hours per week, learning “everything there is to know about mission operations and how to fly a spacecraft,” Ruswick said.
Cole Writer, an aerospace engineering student, remembers this training as “nerve-wracking” because he felt intimidated by the flight controllers. But after practicing procedures on his own laptop, he felt more confident, and completed the program to become a command controller.
“It’s nice to be trained by other students who are in the same boat as you and have gone through the same process,” said Adrienne Pickerill, a flight controller who started with the team as a student and earned a master’s in aerospace engineering at the university in May.
As a teenager Writer’s interests focused on flying planes, and he saved money to train for a pilot’s license, earning it the summer after high school graduation. Surprisingly, he has found many overlaps in skills for both activities – following checklists and preventing mistakes. “Definitely high stakes in both cases,” he said.
While working at LASP, the Laboratory for Atmospheric and Space Physics, students at the University of Colorado, Boulder, train to become command controllers who work and manage spacecraft. From monitoring IXPE’s health and safety to sending commands to the spacecraft to look at cosmic objects at the request of scientists, these students are getting a one-of-a-kind hands-on experience. (NASA)Sam Lippincott, now a graduate student lead after serving as a command controller as an undergraduate, has been a lifelong sci-fi fan, but took a career in space more seriously his sophomore year of college. “For people that want to go into the aerospace or space operations industry, it’s always important to remember that you’ll never stop learning, and it’s important to remain humble in your abilities, and always be excited to learn more,” he said.
De Herrera-Schnering got hooked on the idea of becoming a scientist the first time she saw the Milky Way. On a camping trip when she was 10 years old, she spotted the galaxy as she went to use the outhouse in the middle of the night. “I woke up my parents, and we just laid outside and we were just stargazing,” she said. “After that I knew I was set on what I wanted to do.”
Rithik Gangopadhyay, who trained as an undergraduate command controller and continued at LASP as a graduate student lead, had been interested in puzzles and problem-solving as a kid and had a book about planets that fascinated him. “There’s so much out there and so much we don’t know, and I think that’s what really pushed me to do aerospace and do this opportunity of being a command controller,” he said.
Coding is key to mission operations, and much of it is done in the Python language. Sometimes the work of flying a spacecraft feels like any other kind of programming — but occasionally, team members step back and consider that they are part of the grand mission of exploring the universe.
“If it’s your job for a couple of years, it starts to be like, ‘oh, let’s go ahead and do that, it’s just another Tuesday.’ But if you step back and think about it on a high-level basis, it’s really something special,” Pichler said. “It’s definitely profound.”
NASA Expands Human Exploration Rover Challenge to Middle Schools

Following a 2024 competition that garnered international attention, NASA is expanding its Human Exploration Rover Challenge (HERC) to include a remote control division and inviting middle school students to participate.
The 31st annual competition is scheduled for April 11-12, 2025, at the U.S. Space & Rocket Center, near NASA’s Marshall Space Flight Center in Huntsville, Alabama. HERC is managed by NASA’s Southeast Regional Office of STEM Engagement at Marshall. The HERC 2025 Handbook has been released, with guidelines for the new remote control (RC) division – ROVR (Remote-Operated Vehicular Research) – and detailing updates for the human-powered division.
“Our RC division significantly lowers the barrier to entry for schools who don’t have access to manufacturing facilities, have less funding, or who are motivated to compete but don’t have the technical mentorship required to design and manufacture a safe human-powered rover,” said Chris Joren, HERC technical coordinator. “We are also opening up HERC to middle school students for the first time. The RC division is inherently safer and less physically intensive, so we invite middle school teams and organizations to submit a proposal to be a part of HERC 2025.”
Another change for 2025 is the removal of task sites on the course for the human-powered rover division, allowing teams to focus on their rover’s design. Recognized as NASA’s leading international student challenge, the 2025 challenge aims to put competitors in the mindset of the Artemis campaign as they pitch an engineering design for a lunar terrain vehicle – they are astronauts piloting a vehicle, exploring the lunar surface while overcoming various obstacles.
“The HERC team wanted to put together a challenge that allows students to gain 21st century skills, workforce readiness skills, and skills that are transferable,” said Vemitra Alexander, HERC activity lead. “The students have opportunities to learn and apply the engineering design process model, gain public speaking skills, participate in community outreach, and learn the art of collaborating with their peers. I am very excited about HERC’s growth and the impact it has on the students we serve nationally and internationally.”
Students interested in designing, developing, building, and testing rovers for Moon and Mars exploration are invited to submit their proposals to NASA through Sept. 19.
More than 1,000 students with 72 teams from around the world participated in the 2024 challenge as HERC celebrated its 30th anniversary as a NASA competition. Participating teams represented 42 colleges and universities and 30 high schools from 24 states, the District of Columbia, Puerto Rico, and 13 other nations from around the world.
“We saw a massive jump in recognition, not only from within the agency as NASA Chief Technologist A.C. Charania attended the event, but with several of our international teams meeting dignitaries and ambassadors from their home countries to cheer them on,” Joren said. “The most impressive thing will always be the dedication and resilience of the students and their mentors. No matter what gets thrown at these students, they still roll up to the start line singing songs and waving flags.”
HERC is one of NASA’s eight Artemis Student Challenges reflecting the goals of the Artemis campaign, which seeks to land the first woman and first person of color on the Moon while establishing a long-term presence for science and exploration. NASA uses such challenges to encourage students to pursue degrees and careers in the STEM fields of science, technology, engineering, and mathematics.
Since its inception in 1994, more than 15,000 students have participated in HERC – with many former students now working at NASA, or within the aerospace industry.

A SAFER Way
On Sept. 16, 1994, astronaut Mark C. Lee tested out the Simplified Aid for EVA Rescue (SAFER) system, a system designed for use in the event a crew member becomes untethered while conducting a spacewalk. Occurring during the STS-64 mission, this was the first untethered U.S. spacewalk in 10 years.
This SAFER test was the first phase of a larger SAFER program whose objectives were to establish a common set of requirements for both space shuttle and space station program needs, develop a flight demonstration of SAFER, validate system performance and, finally, develop a production version of SAFER for the shuttle and station programs.
