IXPE Operations Update

On March 23, NASA’s IXPE (Imaging X-ray Polarimetry Explorer) stopped transmitting valid telemetry data. The only previous interruption of IXPE science observations was due to a similar issue in June of 2023.

On March 26, using procedures developed following that previous interruption, the team initiated a spacecraft avionics reset to address the issue, which put IXPE into a planned safe mode. The team has confirmed that IXPE is once again transmitting valid telemetry data and is now working to resume science operations, in as rapid and safe a manner as possible. The spacecraft is in good health.

Launched in 2021, IXPE is a space observatory built to discover the secrets of some of the most extreme cosmic objects – the remnants of supernova explosions, neutron stars, powerful particle streams ejected by feeding black holes, and more. The observatory is NASA’s first mission to study the polarization of X-rays from many different types of celestial objects. Follow the IXPE blog for further updates.

NASA Selects First Lunar Instruments for Artemis Astronaut Deployment

Tue, 03/26/2024 - 4:22pm

NASA has chosen the first science instruments designed for astronauts to deploy on the surface of the Moon during Artemis III. Once installed near the lunar South Pole, the three instruments will collect valuable scientific data about the lunar environment, the lunar interior, and how to sustain a long-duration human presence on the Moon, which will help prepare NASA to send astronauts to Mars.

“Artemis marks a bold new era of exploration, where human presence amplifies scientific discovery. With these innovative instruments stationed on the Moon’s surface, we’re embarking on a transformative journey that will kick-start the ability to conduct human-machine teaming – an entirely new way of doing science,” said NASA Deputy Administrator Pam Melroy. “These three deployed instruments were chosen to begin scientific investigations that will address key Moon to Mars science objectives.”

The instruments will address three Artemis science objectives: understanding planetary processes, understanding the character and origin of lunar polar volatiles, and investigating and mitigating exploration risks. They were specifically chosen because of their unique installation requirements that necessitate deployment by humans during moonwalks. All three payloads were selected for further development to fly on Artemis III that’s targeted to launch in 2026, however, final manifesting decisions about the mission will be determined at a later date. Members of these payload teams will become members of NASA’s Artemis III science team.

The Lunar Environment Monitoring Station (LEMS) is a compact, autonomous seismometer suite designed to carry out continuous, long-term monitoring of the seismic environment, namely ground motion from moonquakes, in the lunar south polar region. The instrument will characterize the regional structure of the Moon’s crust and mantle, which will add valuable information to lunar formation and evolution models. LEMS previously received four years of NASA’s Development and Advancement of Lunar Instrumentation funding for engineering development and risk reduction. It is intended to operate on the lunar surface from three months up to two years and may become a key station in a future global lunar geophysical network. LEMS is led by Dr. Mehdi Benna, from the University of Maryland, Baltimore County.

Lunar Effects on Agricultural Flora (LEAF) will investigate the lunar surface environment’s effects on space crops. LEAF will be the first experiment to observe plant photosynthesis, growth, and systemic stress responses in space-radiation and partial gravity.  Plant growth and development data, along with environmental parameters measured by LEAF, will help scientists understand the use of plants grown on the Moon for both human nutrition and life support on the Moon and beyond. LEAF is led by Christine Escobar of Space Lab Technologies, LLC, in Boulder, Colorado.

The Lunar Dielectric Analyzer (LDA) will measure the regolith’s ability to propagate an electric field, which is a key parameter in the search for lunar volatiles, especially ice. It will gather essential information about the structure of the Moon’s subsurface, monitor dielectric changes caused by the changing angle of the Sun as the Moon rotates, and look for possible frost formation or ice deposits. LDA, an internationally contributed payload, is led by Dr. Hideaki Miyamoto of the University of Tokyo and supported by JAXA (Japan Aerospace Exploration Agency).

“These three scientific instruments will be our first opportunity since Apollo to leverage the unique capabilities of human explorers to conduct transformative lunar science,” said Joel Kearns, deputy associate administrator for exploration in NASA’s Science Mission Directorate in Washington. “These payloads mark our first steps toward implementing the recommendations for the high-priority science outlined in the Artemis III Science Definition Team report.”

Artemis III, the first mission to return astronauts to the surface of the Moon in more than 50 years, will explore the south polar region of the Moon, within 6 degrees of latitude from the South Pole. Several proposed landing regions for the mission are located among some of the oldest parts of the Moon. Together with the permanently shadowed regions, they provide the opportunity to learn about the history of the Moon through previously unstudied lunar materials.

With the Artemis campaign, NASA will land the first woman, first person of color, and its first international partner astronaut on the Moon, and establish long-term exploration for scientific discovery and preparation for human missions to Mars for the benefit of all.

Two full-scale development model rovers, part of NASA’s Cooperative Autonomous Distributed Robotic Exploration (CADRE) technology demonstration, drive in the Mars Yard at the agency’s Jet Propulsion Laboratory in Southern California in this image from August 2023. The project is designed to show that a group of robotic spacecraft can work together as a team to accomplish tasks and record data autonomously – without explicit commands from mission controllers on Earth.

A series of Mars Yard tests with the development models confirmed CADRE hardware and software can work together to accomplish key goals for the project. The rovers drove together in formation and adjusted their plans as a group when faced with unexpected obstacles.

CADRE is slated to arrive at the Reiner Gamma region of the Moon through NASA’s Commercial Lunar Payload Services (CLPS) initiative. The network of robots will spend the daylight hours of a single lunar day – about 14 Earth days – conducting experiments that will test their capabilities.

NASA’s OSIRIS-REx Mission Awarded Collier Trophy

Tue, 03/26/2024 - 2:49pm

NASA and the OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification, and Security – Regolith Explorer) mission team have won the National Aeronautic Association’s (NAA) Robert J. Collier Trophy. NAA awards the trophy annually for what it determines is “the greatest achievement in aerospace and astronautics in America.” The OSIRIS-REx team will be celebrated at an award dinner on June 13, 2024, in Washington, D.C. 

The NAA bestowed the Robert J. Collier Trophy on the team behind NASA’s OSIRIS-REx, acknowledging the mission’s place in aerospace history by being the first U.S. mission to collect a sample from an asteroid and deliver it to Earth for study.

Erika Blumenfeld, creative lead for the Advanced Imaging and Visualization of Astromaterials (AIVA) and Joe Aebersold, project management lead, captured this picture using manual high-resolution precision photography and a semi-automated focus stacking procedure. The result is an image that can be zoomed in on to show extreme detail of the sample. The remaining sample material includes dust and rocks up to about .4 in (one cm) in size.NASA/Erika Blumenfeld & Joseph Aebersold

“Congratulations to the OSIRIS-REx team on this well-deserved honor,” said NASA Administrator Bill Nelson. “By successfully designing, building, and carrying out the first U.S. mission to collect an asteroid sample, NASA proved once again that we do big things. Things that inspire the world. We look forward to the incredible science to come that will tell us more about our solar system and help protect humanity here on Earth.”

Established more than a century ago, the award has marked major achievements in the timeline of flight, including Orville Wright in 1913 for developing the automatic stabilizer; Air Force test pilot Chuck Yeager for his sound-barrier-breaking 1947 flight of the X-1 rocket plane; the crews of NASA’s Apollo 8, 11, and 15 for their missions to the Moon in the late 1960s and early ’70s; and NASA’s Ingenuity Mars Helicopter.

The OSIRIS-REx team includes NASA’s Goddard Space Flight Center in Greenbelt, Maryland; Lockheed Martin in Littleton, Colorado; University of Arizona, Tucson; and KinetX in Tempe, Arizona.

The sample from the ancient asteroid Bennu that OSIRIS-REx delivered to Earth in September 2023 will give researchers worldwide a glimpse into the earliest days of our solar system, offering insights into planet formation and the origin of organics essential for life on Earth. Data collected by the spacecraft combined with future analysis of the Bennu sample will also aid our understanding of asteroids that could impact Earth.

The Collier Trophy adds to the recent Robert H. Goddard Memorial Trophy received by NASA’s OSIRIS-REx team in March 2024.

Following its successful sample return, the OSIRIS-REx spacecraft was renamed OSIRIS-APEX and will now enter an extended mission to visit and study near-Earth asteroid Apophis in 2029.

NASA Goddard provides overall mission management, systems engineering, and the safety and mission assurance for OSIRIS-REx. Dante Lauretta of the University of Arizona, Tucson, is the principal investigator. The university leads the science team and the mission’s science observation planning and data processing. Lockheed Martin Space in Littleton, Colorado, built the spacecraft and provides flight operations. Goddard and KinetX Aerospace are responsible for navigating the OSIRIS-REx spacecraft. Processing and curation for OSIRIS-REx’s Bennu sample takes place at NASA’s Johnson Space Center in Houston. International partnerships on this mission include the OSIRIS-REx Laser Altimeter instrument from CSA (the Canadian Space Agency) and asteroid sample science collaboration with JAXA’s (the Japan Aerospace Exploration Agency) Hayabusa2 mission. OSIRIS-REx is the third mission in NASA’s New Frontiers Program, managed by the agency’s Marshall Space Flight Center in Huntsville, Alabama, for the agency’s Science Mission Directorate at NASA Headquarters in Washington.

Order Up: High School Students Compete to Launch Their Food into Space with NASA HUNCH Culinary Competition

Tue, 03/26/2024 - 2:18pm
3 Min Read Order Up: High School Students Compete to Launch Their Food into Space with NASA HUNCH Culinary Competition High School students in chef jackets line long black tables at NASA's Langley Research Center preparing savory breakfast dishes fit for astronauts onboard the International Space Station.

On Monday, Feb. 26, visitors to the Integrated Engineering Services Building at NASA’s Langley Research Center in Hampton, Virginia, were greeted by the mouthwatering smell of roasted garlic, sautéed peppers and onions, fragrant herbs, and the unexpected discovery that the building’s main hallway had been turned into a pop-up kitchen for local high school students.

These students were participants in NASA HUNCH Culinary. NASA HUNCH (High School Students United with NASA to Create Hardware) is a Project Based Learning program where high school students participate in the design and fabrication of real world valued products for NASA. HUNCH has six areas of focus that students may choose to participate in: Precision Machining, Softgoods, Design and Prototype, Food Science, Communications, and Software.

The HUNCH Astronaut Culinary Program provides students the opportunity to create dishes for astronauts aboard the International Space Station. Students must create tasty recipes following a specific food processing procedure and meeting certain nutritional requirements. These dishes must meet the standards of the NASA Johnson Space Center Food Lab in Houston, Texas.

Through this program, students gain culinary experience as well as experience with research and presenting their work in a professional environment. Students spend weeks perfecting their recipes so that on competition day, they can recreate their dishes in person at various NASA centers across the country.

This year, HUNCH Culinary student teams were tasked with the challenge of creating a savory breakfast dish that included a vegetable. The recipes had to fall between 150 and 350 calories, contain less than 12 grams of fat and 250 milligrams of sodium, have at least one gram of fiber, and “must process well for spaceflight and for use in microgravity” among several other requirements.

An eager hand reaches for a small serving of eggs scrambled with vegetables and topped with seeds as a larger skillet of the savory breakfast dish sits to the left.NASA/Angelique Herring

Several students described challenges around creating a recipe under these guidelines. Nyland Clay, a student at Landstown High School in Virginia Beach, explained his team’s problem solving around the minimal sodium guideline.

“We were able to work around that by using different types of flavors in order to substitute for the extra sodium,” he said. “One of the ways we did this was with poblano peppers. When seared over a grill, they make a nice smoky flavor that doesn’t add any sodium whatsoever.”

Nyland’s team additionally chose to use ground turkey in their sweet potato hash recipe instead of ground beef to avoid unnecessary fat.

Travis Walker, culinary instructor at Phoebus High School in Hampton and former executive catering chef manager for the NASA Langley Exchange, spoke highly of his students as his reason for teaching.

“The most rewarding part is just watching the growth of the kids,” he said. “From the day you get them and they can’t boil water, to the time they get here and they’re in these competitions and excelling — that’s the most rewarding part.”

The student groups with the highest scores will be invited to Johnson Space Center in Houston for a final competition where their dishes will be judged by Johnson Food Lab personnel, industry professionals, the ISS program office, and astronauts. The criteria are quality, taste, and the students’ work on the research paper and presentation video. The winning entree will be processed by the Johnson Space Center Food Lab and sent up to the station for the astronauts to enjoy.

After Eugene Malinskiy saw a physician assistant trip over arthroscopic camera cords during a medical procedure, he and his brother, Ilya, set out to develop a wireless arthroscopic camera.

Early in the development process, the Malinskiys got a boost from engineers at NASA’s Glenn Research Center in Cleveland, who advised on technical specifications through the center’s Adopt-a-City program. This agency program enabled Glenn engineers to consult with them pro bono via a Space Act Agreement with the city of Cleveland.

The team also consulted with NASA engineers on their plan to use the ultra-wideband protocol – radio technology enabling encrypted transfer of a high-definition signal – and their planned processors and chips used in the device’s central processing unit.

Ilya Malinskiy said the company gave investors the space agency engineers’ feedback. “Being able to say we had very skilled NASA engineers take a look at our device and say we should keep going was very, very useful.”

It turned out that the first wireless arthroscopic camera wasn’t entirely unlike CubeSats – tiny satellites that often orbit Earth in clusters.

“We had a lot of the same issues,” Ilya Malinskiy said. “We both have very small devices that need reliable power without adding a lot of weight.”

Ultimately, the NASA engineers connected the Lazurite team with several high-fidelity aerospace lithium-ion battery vendors.

In 2022, Lazurite’s ArthroFree Wireless Camera System became the first FDA-cleared wireless camera system for minimally invasive surgery. Since then, the device has assisted in countless surgeries, and the company has raised tens of millions of dollars.

New NASA Software Simulates Science Missions for Observing Terrestrial Freshwater

Tue, 03/26/2024 - 9:00am

4 min read

New NASA Software Simulates Science Missions for Observing Terrestrial Freshwater A map describing freshwater accumulation (blue) and loss (red), using data from NASA’s Gravity Recovery and Climate Experiment (GRACE) satellites. A new Observational System Simulation Experiment (OSSE) will help researchers design science missions dedicated to monitoring terrestrial freshwater storage. Image Credit: NASA Image Credit: NASA

From radar instruments smaller than a shoebox to radiometers the size of a milk carton, there are more tools available to scientists today for observing complex Earth systems than ever before. But this abundance of available sensors creates its own unique challenge: how can researchers organize these diverse instruments in the most efficient way for field campaigns and science missions?

To help researchers maximize the value of science missions, Bart Forman, an Associate Professor in Civil and Environmental Engineering at the University of Maryland, and a team of researchers from the Stevens Institute of Technology and NASA’s Goddard Space Flight Center, prototyped an Observational System Simulation Experiment (OSSE) for designing science missions dedicated to monitoring terrestrial freshwater storage.

“You have different sensor types. You have radars, you have radiometers, you have lidars – each is measuring different components of the electromagnetic spectrum,” said Bart Forman, an Associate Professor in Civil and Environmental Engineering at the University of Maryland. “Different observations have different strengths.”

Terrestrial freshwater storage describes the integrated sum of freshwater spread across Earth’s snow, soil moisture, vegetation canopy, surface water impoundments, and groundwater. It’s a dynamic system, one that defies traditional, static systems of scientific observation.

Forman’s project builds on prior technology advancements he achieved during an earlier Earth Science Technology Office (ESTO) project, in which he developed an observation system simulation experiment for mapping terrestrial snow. 

It also relies heavily on innovations pioneered by NASA’s Land Information System (LIS) and NASA’s Trade-space Analysis Tool for Designing Constellations (TAT-C), two modeling tools that began as ESTO investments and quickly became staples within the Earth science community.

Forman’s tool incorporates these modeling programs into a new system that provides researchers with a customizable platform for planning dynamic observation missions that include a diverse collection of spaceborne data sets.

In addition, Forman’s tool also includes a “dollars-to-science” cost estimate tool that allows researchers to assess the financial risks associated with a proposed mission.

Together, all of these features provide scientists with the ability to link observations, data assimilation, uncertainty estimation, and physical models within a single, integrated framework.

“We were taking a land surface model and trying to merge it with different space-based measurements of snow, soil moisture, and groundwater to see if there was an optimal combination to give us the most bang for our scientific buck,” explained Forman.

While Forman’s tool isn’t the first information system dedicated to science mission design, it does include a number of novel features. In particular, its ability to integrate observations from spaceborne passive optical radiometers, passive microwave radiometers, and radar sources marks a significant technology advancement.

Forman explained that while these indirect observations of freshwater include valuable information for quantifying freshwater, they also each contain their own unique error characteristics that must be carefully integrated with a land surface model in order to provide estimates of geophysical variables that scientists care most about.

Forman’s software also combines LIS and TAT-C within a single software framework, extending the capabilities of both systems to create superior descriptions of global terrestrial hydrology.

Indeed, Forman stressed the importance of having a large, diverse team that features experts from across the Earth science and modeling communities.

“It’s nice to be part of a big team because these are big problems, and I don’t know the answers myself. I need to find a lot of people that know a lot more than I do and get them to sort of jump in and roll their sleeves up and help us. And they did,” said Forman.

Having created an observation system simulation experiment capable of incorporating dynamic, space-based observations into mission planning models, Forman and his team hope that future researchers will build on their work to create an even better mission modeling program.

For example, while Forman and his team focused on generating mission plans for existing sensors, an expanded version of their software could help researchers determine how they might use future sensors to gather new data.

“With the kinds of things that TAT-C can do, we can create hypothetical sensors. What if we double the swath width? If it could see twice as much space, does that give us more information? Simultaneously, we can ask questions about the impact of different error characteristics for each of these hypothetical sensors and explore the corresponding tradeoff.” said Forman.

NASA Remembers Former NASA Johnson Director George W. S. Abbey

Mon, 03/25/2024 - 5:45pm

March 25, 2024

Former NASA Johnson Space Center Director George W. S. Abbey

RELEASE J24-008

NASA Remembers Former NASA Johnson Director George W. S. Abbey

George W. S. Abbey, former director of NASA’s Johnson Space Center, died Sunday, March 24, in Houston after an illness. The Seattle native was 91. 

“A true visionary, Mr. Abbey demonstrated transformational leadership as Johnson’s seventh center director. During his tenure, the space shuttle flew more than 25 successful missions; the joint U.S. and Russian Shuttle-Mir Program was completed, providing important information for long-duration spaceflight,” said Vanessa Wyche, director of NASA Johnson. “He was instrumental in the Johnson team’s involvement in developing and launching the first elements of the International Space Station, which marked the beginning of a new era in space exploration. On behalf of NASA’s Johnson Space Center, we send our condolences to Mr. Abbey’s loved ones during this difficult time.”

Abbey had a long and storied career in human spaceflight that began with NASA in 1964 and continued beyond his retirement from the agency. As the director of flight operations, he oversaw selection of NASA’s first space shuttle astronauts, mission operations, and the new shuttle program’s approach and landing tests.

From 1987 to 1993, Abbey supported NASA Headquarters in Washington, serving in key roles in human spaceflight, and on the National Space Council. He returned to Johnson in 1994, first as deputy director, then director, leading the development and launch of the space station. Abbey retired from the agency in 2003.

In December 2021, NASA named the Saturn V rocket display park outside Johnson’s main gate for Abbey. Abbey instituted the Longhorn Project, a vital STEM program that provides students with hands-on agricultural experiences and academic scholarships. He leaves behind a legacy of excellence and lasting impact as he will continue to inspire over 1.2 million visitors who visit the George W.S. Abbey Rocket Park annually.

“Abbey’s dedication to human spaceflight remained steadfast. As the NASA family mourns his passing, we are grateful for his leadership and the legacy he leaves behind,” Wyche said.

Abbey is survived by his five children, his eight grandchildren, three great-grandchildren, nieces, and nephews.

NASA to Launch Sounding Rockets into Moon’s Shadow During Solar Eclipse

NASA to Launch Sounding Rockets into Moon’s Shadow During Solar Eclipse

NASA will launch three sounding rockets during the total solar eclipse on April 8, 2024, to study how Earth’s upper atmosphere is affected when sunlight momentarily dims over a portion of the planet.

The Atmospheric Perturbations around Eclipse Path (APEP) sounding rockets will launch from NASA’s Wallops Flight Facility in Virginia to study the disturbances in the ionosphere created when the Moon eclipses the Sun. The sounding rockets had been previously launched and successfully recovered from White Sands Test Facility in New Mexico, during the October 2023 annular solar eclipse. They have been refurbished with new instrumentation and will be relaunched in April 2024. The mission is led by Aroh Barjatya, a professor of engineering physics at Embry-Riddle Aeronautical University in Florida, where he directs the Space and Atmospheric Instrumentation Lab.

The sounding rockets will launch at three different times: 45 minutes before, during, and 45 minutes after the peak local eclipse. These intervals are important to collect data on how the Sun’s sudden disappearance affects the ionosphere, creating disturbances that have the potential to interfere with our communications.

This conceptual animation is an example of what observers might expect to see during a total solar eclipse, like the one happening over the United States on April 8, 2024. NASA’s Scientific Visualization Studio.

The ionosphere is a region of Earth’s atmosphere that is between 55 to 310 miles (90 to 500 kilometers) above the ground. “It’s an electrified region that reflects and refracts radio signals, and also impacts satellite communications as the signals pass through,” said Barjatya. “Understanding the ionosphere and developing models to help us predict disturbances is crucial to making sure our increasingly communication-dependent world operates smoothly.”

The ionosphere forms the boundary between Earth’s lower atmosphere – where we live and breathe – and the vacuum of space. It is made up of a sea of particles that become ionized, or electrically charged, from the Sun’s energy, or solar radiation. When night falls, the ionosphere thins out as previously ionized particles relax and recombine back into neutral particles. However, Earth’s terrestrial weather and space weather can impact these particles, making it a dynamic region and difficult to know what the ionosphere will be like at a given time. 

An animation depicts changes in the ionosphere over a 24-hour period. The red and yellow swaths represent high-density ionized particles during the day. The purple dots represent neutral, relaxed particles at night. NASA/Krystofer Kim

It’s often difficult to study short-term changes in the ionosphere during an eclipse with satellites because they may not be at the right place or time to cross the eclipse path. Since the exact date and times of the total solar eclipse are known, NASA can launch targeted sounding rockets to study the effects of the eclipse at the right time and at all altitudes of the ionosphere.

As the eclipse shadow races through the atmosphere, it creates a rapid, localized sunset that triggers large-scale atmospheric waves and small-scale disturbances, or perturbations. These perturbations affect different radio communication frequencies. Gathering the data on these perturbations will help scientists validate and improve current models that help predict potential disturbances to our communications, especially high frequency communication.

The APEP rockets are expected to reach a maximum altitude of 260 miles (420 kilometers). Each rocket will measure charged and neutral particle density and surrounding electric and magnetic fields. “Each rocket will eject four secondary instruments the size of a two-liter soda bottle that also measure the same data points, so it’s similar to results from fifteen rockets, while only launching three,” explained Barjatya. Three secondary instruments on each rocket were built by Embry-Riddle, and the fourth one was built at Dartmouth College in New Hampshire.

In addition to the rockets, several teams across the U.S. will also be taking measurements of the ionosphere by various means. A team of students from Embry-Riddle will deploy a series of high-altitude balloons. Co-investigators from the Massachusetts Institute of Technology’s Haystack Observatory in Massachusetts, and the Air Force Research Laboratory in New Mexico, will operate a variety of ground-based radars taking measurements. Using this data, a team of scientists from Embry-Riddle and Johns Hopkins University Applied Physics Laboratory are refining existing models. Together, these various investigations will help provide the puzzle pieces needed to see the bigger picture of ionospheric dynamics.

A sounding rocket is able to carry science instruments between 30 and 300 miles above Earth’s surface. These altitudes are typically too high for science balloons and too low for satellites to access safely, making sounding rockets the only platforms that can carry out direct measurements in these regions.

When the APEP sounding rockets launched during the 2023 annular solar eclipse, scientists saw a sharp reduction in the density of charged particles as the annular eclipse shadow passed over the atmosphere. “We saw the perturbations capable of affecting radio communications in the second and third rockets, but not during the first rocket that was before peak local eclipse” said Barjatya. “We are super excited to relaunch them during the total eclipse, to see if the perturbations start at the same altitude and if their magnitude and scale remain the same.”

The next total solar eclipse over the contiguous U.S. is not until 2044, so these experiments are a rare opportunity for scientists to collect crucial data.

The APEP launches will be live streamed via NASA’s Wallops’ official YouTube page and featured in NASA’s official broadcast of the total solar eclipse. The public can also watch the launches in person from 1-4 p.m. at the NASA Wallops Flight Facility Visitor Center.

NASA’s OSIRIS-REx Mission Awarded Robert Goddard Memorial Trophy

Mon, 03/25/2024 - 2:20pm

3 min read

Preparations for Next Moonwalk Simulations Underway (and Underwater)

NASA’s OSIRIS-REx team was selected as the winner of the National Space Club and Foundation’s 2024 Dr. Robert H. Goddard Memorial Trophy for their tremendous work on the first U.S. mission to bring an asteroid sample to Earth. The winning team  received the award at the 67th Annual Robert H. Goddard Memorial Dinner at the Washington Hilton Hotel on March 22, 2024.

The sample return capsule from NASA’s OSIRIS-REx mission is seen shortly after touching down in the desert, Sunday, Sept. 24, 2023, at the Department of Defense’s Utah Test and Training Range. The sample was collected from the asteroid Bennu in October 2020 by NASA’s OSIRIS-REx spacecraft. NASA/Keegan Barber

The OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification, and Security – Regolith Explorer) team includes NASA’s Goddard Space Flight Center in Greenbelt, Maryland; Lockheed Martin in Littleton, Colorado; University of Arizona, Tucson and KinetX in Tempe, Arizona.

The trophy is National Space Club’s highest honor and presented annually to the individual or group who has made a substantial contribution to U.S. leadership in astronautics or rocketry.

“The OSIRIS-REx team’s successful delivery of the asteroid Bennu sample to Earth will enable important scientific discoveries for generations to come,” said Lori Glaze, director of the Planetary Science Division at NASA Headquarters in Washington. “I’m so pleased to see the mission team recognized with the Robert H. Goddard Memorial Trophy for their accomplishments.”

Making U.S. History

Following its launch in 2016, the OSIRIS-REx mission made U.S. space history when it became the first U.S. spacecraft to touch an asteroid and capture a sample on Oct. 20, 2020, and again when it successfully returned with the sample to Earth on Sept. 24, 2023.

The sample, which is the largest asteroid sample ever delivered to Earth, is from the ancient asteroid Bennu and will give researchers worldwide a glimpse into the earliest days of our solar system, offering insights into planet formation and the origin of organics that led to life on Earth. Data collected by the spacecraft combined with future analysis of the Bennu sample will also aid our understanding of asteroids that can impact Earth.

The OSIRIS-REx mission conducted unprecedented centimeter-scale mapping of Bennu, surpassing precision levels achieved for any other planetary body and setting three Guinness World Records for: smallest object orbited by a spacecraft, closest orbit of an asteroid and highest resolution satellite map of any planetary body.

“The OSIRIS-REx mission rewrote U.S. space exploration history,” said Joe Vealencis, president, NSCF. “The data the spacecraft collected, plus all that we have yet to uncover from the sample it brought back, means scientists and engineers will be reaping the benefits of this mission for years to come.”

The Mission Continues

Following its successful sample return, the OSIRIS-REx spacecraft was renamed OSIRIS-APEX and will now enter an extended mission to visit and study near-Earth asteroid Apophis in 2029.

OSIRIS-REx’s success was made possible by the unique contributions of over 1,000 individuals from government and mission partners like the science lead at the University of Arizona, the project team at NASA’s Goddard Space Flight Center, the curation team at NASA’s Johnson Space Center, spacecraft design, operations, and recovery by Lockheed Martin, guidance and navigation at KinetX, and the launch provider at United Launch Alliance.

OSIRIS-REx is the third mission in NASA’s New Frontiers Program, managed by NASA’s Marshall Space Flight Center in Huntsville, Alabama, for the Science Mission Directorate at NASA Headquarters in Washington.

Antarctic Sea Ice Near Historic Lows; Arctic Ice Continues Decline

Mon, 03/25/2024 - 1:00pm
5 Min Read Antarctic Sea Ice Near Historic Lows; Arctic Ice Continues Decline On Feb. 20, 2024, Antarctic sea ice officially reached its minimum extent for the year.

Schindler

Sea ice at both the top and bottom of the planet continued its decline in 2024. In the waters around Antarctica, ice coverage shrank to near-historic lows for the third year in a row. The recurring loss hints at a long-term shift in conditions in the Southern Ocean, likely resulting from global climate change, according to scientists at NASA and the National Snow and Ice Data Center. Meanwhile, the 46-year trend of shrinking and thinning ice in the Arctic Ocean shows no sign of reversing.

“Sea ice acts like a buffer between the ocean and the atmosphere,” said ice scientist Linette Boisvert of NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “Sea ice prevents much of the exchange of heat and moisture from the relatively warm ocean to the atmosphere above it.”

Less ice coverage allows the ocean to warm the atmosphere over the poles, leading to more ice melting in a vicious cycle of rising temperatures.

Historically, the area of sea ice surrounding the Antarctic continent has fluctuated dramatically from year to year while averages over decades have been relatively stable. In recent years, though, sea ice cover around Antarctica has plummeted.

On Feb. 20, 2024, Antarctic sea ice officially reached its minimum extent for the year. This cycle of growth and melting occurs every year, with the ice reaching its smallest size during the Southern Hemisphere’s summer. According to the National Snow and Ice Data Center, this marks the second-lowest sea ice extent recorded by satellites, reflecting a trend of declining coverage over time.

“In 2016, we saw what some people are calling a regime shift,” said sea ice scientist Walt Meier of the National Snow and Ice Data Center at the University of Colorado, Boulder. “The Antarctic sea ice coverage dropped and has largely remained lower than normal. Over the past seven years, we’ve had three record lows.”

This year, Antarctic sea ice reached its lowest annual extent on Feb. 20 with a total of 768,000 square miles (1.99 million square kilometers). That’s 30% below the 1981 to 2010 end-of-summer average. The difference in ice cover spans an area about the size of Texas. Sea ice extent is defined as the total area of the ocean in which the ice cover fraction is at least 15%.

This year’s minimum is tied with February 2022 for the second lowest ice coverage around the Antarctic and close to the 2023 all-time low of 691,000 square miles (1.79 million square kilometers). With the latest ice retreat, this year marks the lowest three-year average for ice coverage observed around the Antarctic continent across more than four decades.

The changes were observed in data collected with microwave sensors aboard the Nimbus-7 satellite, jointly operated by NASA and the National Oceanic and Atmospheric Administration (NOAA), along with satellites in the Defense Meteorological Satellite Program.

Meanwhile, at the other end of the planet, the maximum winter ice coverage in the Arctic Ocean is consistent with an ongoing 46-year decline. Satellite images reveal that the total area of the Arctic Ocean covered in sea ice reached 6 million square miles (15.65 million square kilometers) on March 14. That’s 247,000 square miles (640,000 square kilometers) less ice than the average between 1981 and 2010. Overall, the maximum winter ice coverage in the Arctic has shrunk by an area equivalent to the size of Alaska since 1979.

This year’s Arctic ice maximum is the 14th lowest on record. Complex weather patterns make it difficult to predict what will happen in any given year.

The Arctic Ocean sea ice reached its annual maximum on March 14, continuing the long-term decline in ice at the poles.Chart by Lauren Dauphin/NASA Earth Observatory, using data from the National Snow and Ice Data Center.

Shrinking ice makes Earth more susceptible to solar heating. “The sea ice and the snow on top of it are very reflective,” Boisvert said. “In the summer, if we have more sea ice, it reflects the Sun’s radiation and helps keep the planet cooler.”

On the other hand, the exposed ocean is darker and readily absorbs solar radiation, capturing and retaining that energy and ultimately contributing to warming in the planet’s oceans and atmosphere. 

Sea ice around the poles is more susceptible to the weather than it was a dozen years ago. Ice thickness measurements collected with laser altimeters aboard NASA’s ICESat-2 satellite show that less ice has managed to stick around through the warmer months. This means new ice must form from scratch each year, rather than building on old ice to make thicker layers. Thinner ice, in turn, is more prone to melting than multi-year accumulations.

“The thought is that in a couple of decades, we’re going to have these essentially ice-free summers,” Boisvert said, with ice coverage reduced below 400,000 square miles (1 million square kilometers) and most of the Arctic Ocean exposed to the Sun’s warming glare.

It’s too soon to know whether recent sea ice lows at the South Pole point to a long-term change rather than a statistical fluctuation, but Meier believes long term declines are inevitable.

“It’s only a matter of time,” he said. “After six, seven, eight years, it’s starting to look like maybe it’s happening. It’s just a question of whether there’s enough data to say for sure.”

Early Adopters of NASA’s PACE Data to Study Air Quality, Ocean Health

Mon, 03/25/2024 - 11:58am

Early Adopters of NASA’s PACE Data to Study Air Quality, Ocean Health

From the atmosphere down to the surface of the ocean, data from NASA’s PACE (Plankton, Aerosol, Cloud, ocean Ecosystem) satellite benefits ecosystems, human health, and underrepresented communities.

Years before the launch in February 2024, mission leaders from NASA teamed with dozens of applied scientists and environmental professionals to prepare for the many practical uses that could be informed by PACE data. PACE’s Early Adopter program integrates science data into business, environmental management, and decision-making activities to benefit society.

A SpaceX Falcon 9 rocket with NASA’s PACE (Plankton, Aerosol, Cloud, ocean Ecosystem) spacecraft stands vertical at Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida on Feb. 5, 2024. PACE is NASA’s newest Earth-observing satellite that will help increase our understanding of Earth’s oceans, atmosphere, and climate by delivering hyperspectral observations of microscopic marine organisms called phytoplankton as well new data on clouds and aerosols. SpaceX

The researchers specialize in a wide range of topics including water resources, fisheries and aquaculture, air quality and health, climate, and agriculture. These early adopters of the science provide a bridge between the PACE team and local communities and decision-makers who need accessible products for public use. Such work can help connect the new frontier of PACE’s hyperspectral and multi-angular polarimetric data to real-world problems – and find new ways to address challenges.

Helping Coastal Communities Keep Fisheries Safe

In coastal communities, knowing the quality of the water is essential for ecosystem health, safe and sustainable seafood, and recreation – not to mention human livelihoods that depend on fisheries.

Phytoplankton are microscopic organisms that live in watery environments. When conditions are right, phytoplankton undergo explosive population growth, creating blooms visible from space. Such a bloom occurred in the North Atlantic Ocean, off the coast of Newfoundland in early August 2010. The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite captured this natural-color image on Aug. 9, 2010.

Marina Marrari, executive director of the Costa Rican Fishing Federation in San José is one of PACE’s early adopters. Marrari and her colleagues developed a mobile app that will pull in data from PACE’s Ocean Color Instrument to help inform the public about harmful algal blooms. Known as pezCA, the app distributes near real-time data about ocean temperature, chlorophyll concentration, and currents as measured by other NASA satellites. Once PACE data is available, the app will be updated to include a product on specific types of harmful algal blooms that can have toxic effects on people and animals.

Bringing Air Quality Alerts to the Midwest

Information on air quality and airborne particles (aerosols) is typically available for dense urban areas like Los Angeles, Atlanta, and New York. Marcela Loría-Salazar, assistant professor at the University of Oklahoma in Norman, plans to use data from PACE’s polarimeters and OCI to study air quality in locations in the middle of the United States, where there tend to be fewer ground-based monitors.

Urban pollution emissions, desert dust, and smoke from wildfires can travel from distant places – across continents or even oceans. (Think of the wildfire smoke that can blow from Alaska and Canada into the central U.S.) PACE gathers global data on this dust and smoke in Earth’s atmosphere every one to two days, and that data is open access – meaning it is available for anyone to find and download free from the Internet.

Smoke from Canadian wildfires drifts slowly south over the United States’ Midwest. The drifting smoke can be seen in this Terra satellite image taken in December 2017 over Lake Michigan, as well as parts of Minnesota, Wisconsin, Indiana, and Ohio. NASA MODIS Rapid Response Team / Jeff Schmaltz

Loría-Salazar and her team can use this information to track aerosols, studying how they change as they move over land, change altitude, and interact with other atmospheric particles. Her goal is to better understand how these aerosols affect human health when they’re inhaled. Her team works with the Oklahoma state government to develop solutions to improve air quality decision-making.

She also works with tribal nations to help inform air quality decisions in their communities. For example, setting prescribed fires is a traditional activity to preserve ecosystems, but the fires do put smoke into the air. By using satellite data, tribal managers can make better-informed decisions about the potential risk of acute smoke exposure on a given day.

Tracking Health of Marine Mammal Ecosystems

Phytoplankton are the center of the marine food web. These microscopic organisms are food for bigger animals like zooplankton, fish, and shellfish – and ultimately whales and dolphins. While PACE can’t directly detect fish or mammals below the surface of the ocean, it can view communities of phytoplankton, which can inform scientists about the ocean ecosystem in which fish and mammals live.

By examining phytoplankton, scientists can gain valuable insights into changes occurring within marine habitats, as these microorganisms often serve as early indicators of regional ecosystem health. Liz Ferguson, CEO and marine ecologist for Ocean Science Analytics, studies marine mammals off the Pacific Coast of North America.

Monitoring plankton communities enhances scientists’ ability to perceive the intricate dynamics within marine ecosystems. By closely monitoring shifts in environmental variables and the behavior of indicator species such as marine mammals, Ferguson can study the impact of climate change on the California current’s ecosystems.

Doubling Up Satellite Data

Some species of phytoplankton produce toxins that can be dangerous for humans, pets, and livestock. When these phytoplankton multiply to large numbers, it’s called a harmful algal bloom.

Richard Stumpf and Michelle Tomlinson, oceanographers with the National Oceanic and Atmospheric Administration (NOAA), use satellite data to study these blooms and help inform communities about their risks. They have been using data from the Ocean and Land Color Instrument on the European Space Agency’s Sentinel-3 satellite, which captures Earth data by measuring certain wavelengths of light. PACE’s Ocean Color Instrument sensor does the same, but as a hyperspectral instrument, it can detect more than 200 wavelengths – more than five times the number observed by Sentinel-3 and other current instruments.

Richard Stumpf examines water from plankton net tows in Lake Erie taken in early summer 2023. A net tow concentrates plankton from the water making it easier to identify what is present, particularly when a bloom is developing. The middle jar is the unfiltered lake water, the top one is from an area that has mostly zooplankton (microscopic animals), and the bottom (greenish) one has cyanobacteria. Courtesy of Richard Stumpf

PACE data can help Stumpf and Tomlinson continue their research on how the color of harmful algal blooms change over time and space. Choosing specific wavelengths of data from PACE can also help verify the data from Sentinel-3 and extend the long-term data record.

The hyperspectral capabilities of PACE can allow scientists and environmental managers to not only spot emerging blooms, but also identify the specific communities of phytoplankton that make up the bloom. Detecting these details helps scientists better inform local water managers about the location, timing, and type of harmful algal blooms, which can help mitigate risks to the public.

Hubble Views a Galaxy Under Pressure

Mon, 03/25/2024 - 11:30am
ESA/Hubble & NASA, M. Sun

This NASA/ESA Hubble Space Telescope image shows LEDA 42160, a galaxy about 52 million light-years from Earth in the constellation Virgo. The dwarf galaxy is one of many forcing its way through the comparatively dense gas in the massive Virgo cluster of galaxies. The pressure exerted by this intergalactic gas, known as ram pressure, has dramatic effects on star formation in LEDA 42160.

The gas and dust that permeates space exerts pressure on a galaxy as it moves. This resistance, called ram pressure, can strip a galaxy of its star-forming gas and dust, reducing or even stopping the creation of new stars. However, ram pressure can also compress gas in the galaxy, which can boost star formation.

The Hubble data used to create this image of LEDA 42160 is part of a project that studied dwarf galaxies undergoing ram pressure stripping that are part of large galaxy clusters, like the Virgo cluster. Studies show that ram pressure stripping can initially cause new stars to form in larger galaxies. The researchers wanted to see if the same holds true for smaller galaxies, like LEDA 42160. The bright patches on LEDA 42160’s lower-right flank may be star-forming regions spurred on by ram pressure stripping. Hubble’s observations of LEDA 42160 will help astronomers determine the processes that created the features we see in this small galaxy.

Optical Fiber Production

Mon, 03/25/2024 - 11:30am
Science in Space: March 2024

Optical fibers are used on Earth and in space for applications in medicine, defense, cybersecurity, and telecommunications. Parabolic research showed that optical fibers produced in microgravity can be higher quality than those made in normal gravity, and the International Space Station provides a potential platform for commercial production of these fibers. The Production of Flawless Space Fiber (Flawless Space Fibers-1) investigation is using the space station to demonstrate new manufacturing technology developed by Flawless Photonics to improve the quality and length of optical fiber produced in space.

Preliminary results have been promising. From mid-February to mid-March, the investigation manufactured a total of more than seven miles (11.9 km) of optical fiber. Eight of the runs (called draws) produced more than 2,200 feet (700 meters) of fiber, demonstrating that the results are repeatable. The investigation also drew more than 3,700 feet (1141 meters) in one day, surpassing the prior record of 82 feet (25 meters) for the longest fiber manufactured in space. Seven of the draws exceeded 2,296 feet (700 meters), demonstrating for the first time that commercial lengths of fiber can be produced in space. The space-drawn fibers are set to return to Earth soon for analysis of their quality.

These fibers are made using ZBLAN, a glass alloy made of zirconium, barium, lanthanum, sodium, and aluminum fluorides, each with different densities and crystallization temperatures. Its unique properties allow light to travel through a fiber over a broader range, providing more than ten times the capacity of traditional silica-based fibers and transmitting considerably more data over the same length of fiber. If fibers can be made long enough and of high enough quality, the increased efficiency of ZBLAN could translate into significant energy savings by reducing the need to boost the signal on long-distance transmissions.

However, when ZBLAN is drawn into fibers on the ground, crystals form that scatter signals and make the fiber brittle. Because crystals grow more slowly in microgravity, the approach is to cool drawn fibers before crystals have a chance to form. Microgravity also counters effects of sedimentation, convection, and buoyancy that limit the length and quality of fibers drawn on Earth. Manufacturers use drop towers to manufacture ZBLAN on Earth, but in-space manufacturing provides much more time to draw longer and eventually better fibers.

Scanning electron microscope images of ZBLAN fibers pulled in microgravity (bottom) and on Earth (top) show the crystallization that occurs in ground-based processing.NASA

The Flawless Space Fibers investigation is sponsored by the ISS National Laboratory and involves support from the  Luxembourg Space Agency, University of Adelaide in Australia, and NASA’s InSpace Production Applications (InSPA). InSPA advances sustainable, scalable, and profitable in-space manufacturing in low Earth orbit, working with the ISS National Lab to provide companies with access to the space station for demonstrating production of advanced materials and products for terrestrial applications. Flawless Space Fibers has achieved three of four goals for ZBLAN set by InSPA, including achieving 20 meters on a single run, repeating that amount on a separate draw, and scaling up to runs of commercial length. The analysis of fibers after return to ground is needed to determine whether the investigation meets InSPA’s fourth goal, producing fiber of ten times greater quality than on Earth.

Results may help reduce gravity-induced defects in optical glass products developed on Earth and advance in-space manufacturing models. The investigation also opens the door to creating other valuable specialty fibers in space.

NASA conducted early work processing ZBLAN in microgravity through Marshall Space Flight Center in the 1990s and early 2000s. Development of ZBLAN manufacturing on the space station began in 2014.

Other investigations that examined manufacturing ZBLAN optic fibers in microgravity include Optical Fiber Production in Microgravity (Made In Space Fiber Optics), which conducted the first privately funded ZBLAN fiber draw, Fiber Optic Production, and Fiber Optic Production-2 (FOP-2), which first demonstrated repeated production of 20-meter lengths of fiber in microgravity. Another investigation, Fiber Optics Manufacturing in Space (Space Fibers), developed by FOMS Inc, first demonstrated a fully operational space facility for fiber manufacturing.1

These efforts support commercial development of space and low Earth orbit and offer opportunities for development of next-generation technologies in space for applications on Earth.

Partnerships that Prepare for Success: The Research Institution Perspective on the M-STTR Initiative

Mon, 03/25/2024 - 11:07am
3 Min Read Partnerships that Prepare for Success: The Research Institution Perspective on the M-STTR Initiative Dr. Darayas Patel (left), professor of mathematics and computer science at Oakwood University, and four Oakwood University students record data related to their NASA STTR research. Credits: Oakwood University

Editor’s Notes (March 2024): Oakwood University and its small business partner—SSS Optical Technologies, LLCwere awarded a STTR Phase II in November 2023 to continue their work. Also in 2023, M-STTR awards became part of what is now MPLAN.

In 2022, Oakwood University, a Historically Black College based in Huntsville, Alabama, became a first-time research institution participant in NASA’s Small Business Technology Transfer (STTR) program. Partnering with SSS Optical Technologies, LLC (SSSOT) of Huntsville, Alabama, the team received a 2022 Phase I award to develop UV protective coating for photovoltaic solar cells in space. The PANDA (Polymer Anti-damage Nanocomposite Down-converting Armor) technology could be used to protect solar cells, which convert sunlight into energy but can suffer damage from UV rays.

Prior to this STTR award, Oakwood University and SSSOT prepared for the solicitation by participating in a pilot NASA opportunity. In 2021, NASA launched the M-STTR initiative for Minority-Serving Institutions (MSIs) to propose for Small Business Technology Transfer (STTR) research planning grants. The program is a partnership between NASA’s Space Technology Mission Directorate (STMD) and NASA’s Office of STEM Engagement’s Minority University Research and Education Project (MUREP).

The 2021 solicitation resulted in 11 selected proposals to receive M-STTR planning grants—six from Historically Black Colleges and Universities (HBCUs) and five from Hispanic Serving Institutions (HSIs). Oakwood University was among the selected research institution teams; with its grant, the university developed a partnership with SSSOT.

Dr. Darayas Patel, professor of mathematics and computer science at Oakwood University, shared the university perspective on how the M-STTR program helped the team form a partnership and prepare for the 2022 STTR solicitation. Dr. Patel is supporting the Phase I STTR contract, which is the university’s first time working with the SBIR/STTR program. Prior to the NASA STTR award, Oakwood University has received grants from other government agencies, including the Department of Defense and the National Science Foundation. Oakwood University also has past involvement in NASA’s MUREP program, which helps engage, fund, and connect underserved university communities. Learning about opportunities from the MUREP network, the Oakwood University team proposed to the pilot M-STTR program, working together with SSSOT on photovoltaic solar cell technology.

“M-STTR helped us solidify the collaboration with SSSOT by focusing our team on specific, tangible goals.”

Dr. Darayas Patel

Professor at Oakwood University

Oakwood University and SSSOT formed a partnership based on Dr. Patel’s existing relationship with SSSOT’s founder Dr. Sergey Sarkisov, who was on Dr. Patel’s Ph.D. committee at Alabama A&M University. According to Dr. Patel, the M-STTR grant allowed the team to generate preliminary data about the solar cell technology that would later be proposed for the 2022 STTR award. In addition to providing supplementary data for the STTR solicitation, Dr. Patel said, “M-STTR helped us solidify the collaboration with SSSOT by focusing our team on specific, tangible goals.” The result was a more unified team with a defined action plan for approaching the STTR proposal.

When asked what advice he had for other research institutions interested in participating in the NASA SBIR/STTR program, Dr. Patel shared, “Keep your eyes wide open and try to reach out to nearby small businesses interested in transferring your technology to the market. And remember: it should line up with what NASA is looking for.” From working with NASA on these initiatives, Dr. Patel says he has broadened his network within the NASA community, which helps him stay informed of future opportunities.

“Don’t be afraid to go after the things that you’re dreaming about that aren’t necessarily possible right now. We do things all the time now that were impossible 10 years ago! Figure out how to make the impossible possible, if it’s what you want to do.

“One of my cornerstone pinnacles [is], ‘Show up to work [and] life with integrity and intent.’ So, accomplish your goals with integrity, intent, and a mission. Stick to that and have the confidence to do that, and be OK with messing up and failing, and have fun with those things.

“And if you are not doing something that you love, and you’re not having fun, then think about what those things are and go towards that.”

Hubble Sees New Star Proclaiming Presence with Cosmic Lightshow

Hubble Sees New Star Proclaiming Presence with Cosmic Lightshow This new image from NASA’s Hubble Space Telescope features the FS Tau star system. NASA, ESA, and K. Stapelfeldt (NASA JPL); Image Processing: Gladys Kober (NASA/Catholic University of America)

Jets emerge from the cocoon of a newly forming star to blast across space, slicing through the gas and dust of a shining nebula in this new image from NASA’s Hubble Space Telescope.

FS Tau is a multi-star system made up of FS Tau A, the bright star-like object near the middle of the image, and FS Tau B (Haro 6-5B), the bright object to the far right obscured by a dark, vertical lane of dust. The young objects are surrounded by gently illuminated gas and dust of this stellar nursery. The system is only about 2.8 million years old, very young for a star system. Our Sun, by contrast, is about 4.6 billion years old.

FS Tau B is a newly forming star, or protostar, surrounded by a protoplanetary disk, a pancake-shaped collection of dust and gas leftover from the formation of the star that will eventually coalesce into planets. The thick dust lane, seen nearly edge-on, separates what are thought to be the illuminated surfaces of the flared disk.

FS Tau B is likely in the process of becoming a T Tauri star, a type of young variable star that hasn’t begun nuclear fusion yet but is beginning to evolve into a hydrogen-fueled star similar to our Sun. Protostars shine with the heat energy released as the gas clouds from which they are forming collapse, and from the accretion of material from nearby gas and dust. Variable stars are a class of star whose brightness changes noticeably over time.

FS Tau A is itself a T Tauri binary system, consisting of two stars orbiting each other.

Protostars are known to eject fast-moving, column-like streams of energized material called jets, and FS Tau B provides a striking example of this phenomenon. The protostar is the source of an unusual asymmetric, double-sided jet, visible here in blue. Its asymmetrical structure may result from the difference in the rates at which mass is being expelled from the object.

FS Tau B is also classified as a Herbig-Haro object. Herbig–Haro objects form when jets of ionized gas ejected by a young star collide with nearby clouds of gas and dust at high speeds, creating bright patches of nebulosity.

FS Tau is part of the Taurus-Auriga region, a collection of dark molecular clouds that are home to numerous newly forming and young stars, roughly 450 light-years away in the constellations of Taurus and Auriga. Hubble has previously observed this region, whose star-forming activity makes it a compelling target for astronomers. Hubble took these observations as part of an investigation of edge-on dust disks around young stellar objects.

Reducing Risks Through Independent M&S 

Mon, 03/25/2024 - 8:47am

This article is from the 2023 Technical Update.

The NESC Flight Mechanics Technical Discipline Team (TDT) provides support to all NASA Mission Directorates and throughout all mission phases. Highlights from this past year include three critical program support assessments, new discipline-advancing capabilities in simulation tools, and a preview of future efforts by the TDT to capture knowledge and expertise to pass on to the next generation. 

Independent modeling and simulation (M&S) enables new insights into critical subsystem designs and offers opportunities for analyses to reduce risk acceptance for programs. Several ongoing assessments have contributed to improved flight certification processes and risk reduction. The Flight Mechanics TDT sponsored improvements to simulation tools that enabled new solutions to complex problems, and recent NESC Academy recordings captured the latest advancements in the discipline. 

Notional risk scoring reduction through independent M&S

Modeling of crew seat acceleration during entry, decent and landing.

The TDT supported the Commercial Crew Program by independently modeling and simulating commercial providers’ trajectory designs and on-board deorbit, entry, descent, and landing software. This past year, the team assessed the return of additional crew on commercial capsules for contingency scenarios and used independent simulation analyses to confirm this capability poses no significant changes in splashdown conditions, thus ensuring additional options for returning crew safely if the primary return vehicle is disabled. Additionally, the NESC is providing key assessments for manual control using a “paper pilot” based on actual pilot responses. This study enabled manual control as a viable survival scenario if the flight computer fails during deorbit, entry, descent, and landing phases of flight. These efforts contributed to an independent verification and validation of commercial providers’ designs that supported certification of commercial flights to and from the ISS. 

Standing up a new independent M&S effort in support of the Mars Ascent Vehicle, a critical element delivering Martian soil and atmosphere samples for eventual return to Earth, provides value and increases confidence in the design of this key element for the Mars Sample Return Campaign. The Flight Mechanics team is contributing unique methodologies for studying the challenging dynamics of this two-stage solid motor design where the second stage is unguided and spin-stabilized.

Independent M&S of key staging and separation events for the SLS has resulted in affirmation of the SLS trajectory and guidance, navigation and control design. Flight Mechanics TDT members contributed analyses to evaluate the heliocentric disposal of the Interim Cyrogenic Propulsion Stage (ICPS). 

Monte Carlo modeling of the Artemis 1

This past year, the TDT also completed an assessment that explored the interoperability between common mission analysis tools and enabled trajectory sharing between tools to solve more complex mission design problems (page 31). An NESC Technical Bulletin (page 47) and Innovative Technique (page 65) have been published on this topic. 

NESC Academy recordings on trajectory optimization tools and frameworks, electric aircraft sizing methodologies, system optimization, and aerodynamic decelerator systems were important knowledge capture and transfer initiatives. These recordings are available to help train and educate engineers on the tools and processes NESC teams will use for future independent M&S efforts.

Three crew members including NASA astronaut Tracy C. Dyson successfully launched at 8:36 a.m. EDT Saturday from the Baikonur Cosmodrome in Kazakhstan to the International Space Station.

Dyson, along with her crewmates Roscosmos cosmonaut Oleg Novitskiy and spaceflight participant Marina Vasilevskaya of Belarus, will dock to the space station’s Prichal module about 11:09 a.m. on Monday, March 25, on the Soyuz MS-25 spacecraft.

Docking coverage will begin at 10:15 a.m. on NASA+, NASA Television, the NASA app, YouTube, and the agency’s website. NASA also will air coverage, starting at 1:15 p.m., of the crew welcome ceremony on NASA+ once they are aboard the orbital outpost. Learn how to stream NASA TV through a variety of platforms including social media.

When the hatches between the station and the Soyuz open about 1:40 p.m., the new crew members will join NASA astronauts Loral O’Hara, Matthew Dominick, Mike Barratt, and Jeanette Epps, as well as Roscosmos cosmonauts Oleg Kononenko, Nikolai Chub, and Alexander Grebenkin, already living and working aboard the space station.

Novitskiy and Vasilevskaya will be aboard the station for 12 days, before providing the ride home for O’Hara on Saturday, April 6, aboard Soyuz MS-24 for a parachute-assisted landing on steppe of Kazakhstan.

Dyson will spend six months aboard the station as an Expedition 70 and 71 flight engineer, returning to Earth in September with Oleg Kononenko and Nikolai Chub of Roscosmos, who will complete a year-long mission on the laboratory.

This will be the third spaceflight for Dyson, the fourth for Novitskiy, and the first for Vasilevskaya.
