Tech Today: Folding NASA Experience into an Origami Toolkit
3 min read
Preparations for Next Moonwalk Simulations Underway (and Underwater) Though the art of origami is centuries old, until the late 20th century it was considered virtually impossible to make insects or other figures with many long, complex protrusions. That changed with the introduction of math-based origami design, which Lang helped pioneer. Today, he’s still drawn to the challenges presented by insects and other arthropods, and they are well-represented in the menagerie of his origami gallery.After uncovering the mathematical underpinnings of origami, Robert Lang left a 20-year engineering career, including over four years at NASA’s Jet Propulsion Laboratory in Southern California, to pursue his lifelong passion. However, while he was working at JPL, Lang picked up an important key to computational design, allowing him to turn paper into impossibly intricate 3D forms.
In the center’s Micro Devices Laboratory in the late 1980s and early ’90s, Lang worked on building an optical computer that uses light rather than electricity to carry out calculations. This work introduced him to the concept of nonlinear constrained optimization.
Lang explained that a simple nonlinear constrained optimization problem is like packing different-sized balls into a box. The constraint is that the balls can’t overlap, and the solutions are nonlinear because the balls can be any direction or distance from each other. The optimization is making the box as small as possible.
System design optimization for lasers and other components requires minimizing energy consumption, semiconductor materials, and other costs. In origami, optimization means creating the most extensive form possible using a single sheet of paper.
In the mid-1990s, he took his expertise gain at JPL and created an open-source software called TreeMaker, the first program available to design complex origami figures. Lang’s design software uses an equation to map the points that will become features like a head and limbs. It helps decide exactly how far apart any two points have to be, depending on their location in the final shape.
In 2001, he left his last engineering job to become a full-time origamist, and he remains one of the world’s leading figures at the intersection of math and paper folding. Lang’s work ranges from small paper sculptures to huge public art made from metal and other materials, which he co-creates with other artists.
Since Lang left NASA, the agency has called him back in to consult on a few projects that capitalized on his dual background in engineering and origami. One of those was the Starshade concept, a design for a baseball diamond-sized disk that would fold up tightly to fit in a rocket fairing and then unfurl in space. There, it would block the light from a given star so a space telescope could photograph its planets. Credit: NASAThe art of folding has even crept into space technology in recent years. Commercial companies now seek out Lang for his origami and engineering backgrounds to consult on folding hardware, including a collapsible radio antenna and Lawrence Livermore National Laboratory’s Eyeglass space telescope. He’s also returned to NASA to help figure out how to fold large objects for launch inside rocket fairings.
“The irony is that, when I was employed full-time at NASA, I was not working on origami, but after I left, I’ve been invited back a couple of times to work on origami-related projects,” he said.

Hubble Spots a Galaxy Hidden in a Dark Cloud

Hubble Spots a Galaxy Hidden in a Dark Cloud This Hubble image features the spiral galaxy IC 4633. ESA/Hubble & NASA, J. Dalcanton, Dark Energy Survey/DOE/FNAL/DECam/CTIO/NOIRLab/NSF/AURA; Acknowledgement: L. ShatzThe subject of this image taken with the NASA/ESA Hubble Space Telescope is the spiral galaxy IC 4633, located 100 million light-years away from us in the constellation Apus. IC 4633 is a galaxy rich in star-forming activity and also hosts an active galactic nucleus at its core. From our point of view, the galaxy is tilted mostly towards us, giving astronomers a fairly good view of its billions of stars.
However, we can’t fully appreciate the features of this galaxy — at least in visible light — because it’s partially concealed by a stretch of dark dust (lower-right third of the image). This dark nebula is part of the Chamaeleon star-forming region, itself located only around 500 light-years from us, in a nearby part of our Milky Way galaxy. The dark clouds in the Chamaeleon region occupy a large area of the southern sky, covering their namesake constellation but also encroaching on nearby constellations, like Apus. The cloud is well-studied for its treasury of young stars, particularly the cloud Cha I, which both Hubble and the NASA/ESA/CSA James Webb Space Telescope have imaged.
The cloud overlapping IC 4633 lies east of the well-known Cha I, II, and III, and is also known as MW9 and the South Celestial Serpent. Classified as an integrated flux nebula (IFN) — a cloud of gas and dust in the Milky Way galaxy that’s not near to any single star and is only faintly lit by the total light of all the galaxy’s stars — this vast, narrow trail of faint gas that snakes over the southern celestial pole is much more subdued looking than its neighbors. Hubble has no problem making out the South Celestial Serpent, though this image captures only a tiny part of it.

Altitude Chamber Gets Upgrade for Artemis II, Spacecraft Testing Begins
Before the Orion spacecraft is stacked atop NASA’s powerful SLS (Space Launch System) rocket ahead of the Artemis II mission, engineers will put it through a series of rigorous tests to ensure it is ready for lunar flight. In preparation for testing, teams at the agency’s Kennedy Space Center in Florida have made significant upgrades to the altitude chamber where testing will occur.
Several of the tests take place inside one of two altitude chambers in the high bay of the Neil A. Armstrong Operations and Checkout (O&C) Building at Kennedy. These tests, which began on April 10, include checking out electromagnetic interference and electromagnetic compatibility, which demonstrate the capability of the spacecraft when subjected to internally and externally generated electromagnetic energy and verify that all systems perform as they would during the mission.
To prepare for the tests, the west altitude chamber was upgraded to test the spacecraft in a vacuum environment that simulates an altitude of up to 250,000 feet. These upgrades re-activated altitude chamber testing capabilities for the Orion spacecraft at Kennedy. Previous vacuum testing on the Orion spacecraft for Artemis I took place at NASA’s Glenn Research Center in Ohio. Teams also installed a 30-ton crane in the O&C to lift and lower the Orion crew and service module stack into the chamber, lift and lower the chamber’s lid, and move the spacecraft across the high bay.

This event marks the first time, since the Apollo testing, that a spacecraft designed for human exploration of space has entered the chamber for testing. After testing is complete, the spacecraft will return to the Final Assembly and Systems Testing, or FAST, cell in the O&C for further work. Later this summer, teams will lift Orion back into the altitude chamber to conduct a test that simulates as close as possible the conditions in the vacuum of deep space.
Originally used to test environmental and life support systems on the lunar and command modules during the Apollo Program, the interior of each altitude chamber measures 33 feet in diameter and 44 feet high and was designed to simulate the vacuum equivalent of up to 200,000 feet in a deep space environment. Both chambers were rated for astronaut crews to operate flight systems during tests.

New LED lights replaced the previous lighting system, and equipment from the Apollo days was removed. A pressure control system was added to the chamber that provides precise control of pressure levels. Two new pumps remove the air from the chamber to create a vacuum. New guardrails and service platforms replaced the older platforms inside the chamber.
A new control room overlooks the upgraded chamber. It contains several workstations and communication equipment. The chamber control and monitoring system was upgraded to handle operation of all the remotely controlled hardware and subsystems that make up the vacuum testing capability.
“It was an amazing opportunity to lead a diverse and exceptional team to re-activate a capability for testing the NASA’s next generation spacecraft that will carry humans back to the Moon,” said Marie Reed, West Altitude Chamber Reactivation Project Manager. “The team of more than 70 aerospace professionals, included individuals from NASA, Lockheed Martin, Artic Slope Research Corps, Jacobs Engineering, and every discipline area imaginable. This project required long hours of dedication and exceptional coordination to enable the successful turn-around and activation in time for this Artemis II spacecraft testing.”

Media Get Close-Up of NASA’s Jupiter-Bound Europa Clipper
4 min read
Preparations for Next Moonwalk Simulations Underway (and Underwater) Members of the media visited a clean room at JPL April 11 to get a close-up look at NASA’s Europa Clipper spacecraft and interview members of the mission team. The spacecraft is expected to launch in October 2024 on a six-year journey to the Jupiter system, where it will study the ice-encased moon Europa.NASA/JPL-CaltechExcitement is mounting as the largest spacecraft NASA has ever built for a planetary mission gets readied for an October launch.
Engineers at NASA’s Jet Propulsion Laboratory in Southern California are running final tests and preparing the agency’s Europa Clipper spacecraft for the next leg of its journey: launching from NASA’s Kennedy Space Center in Florida. Europa Clipper, which will orbit Jupiter and focus on the planet’s ice-encased moon Europa, is expected to leave JPL later this spring. Its launch period opens on Oct. 10.
Members of the media put on “bunny suits” — outfits to protect the massive spacecraft from contamination — to see Europa Clipper up close in JPL’s historic Spacecraft Assembly Facility on Thursday, April 11. Project Manager Jordan Evans, Launch-to-Mars Mission Manager Tracy Drain, Project Staff Scientist Samuel Howell, and Assembly, Test, and Launch Operations Cable Harness Engineer Luis Aguila were on the clean room floor, while Deputy Project Manager Tim Larson, and Mission Designer Ricardo Restrepo were in the gallery above to explain the mission and its goals.
The viewing gallery above High Bay 1 in JPL’s historic Spacecraft Assembly Facility provided members of the media with a vantage point to observe the clean room where Europa Clipper was put together.NASA/JPL-Caltech Europa Clipper Science Communications Lead Cynthia Phillips explains the science of the mission to members of the media in von Kármán Auditorium at the agency’s Jet Propulsion Laboratory on April 11. A cutaway model showing the moon’s layers can be seen behind Phillips.NASA/JPL-CaltechPlanning of the mission began in 2013, and Europa Clipper was officially confirmed by NASA as a mission in 2019. The trip to Jupiter is expected to take about six years, with flybys of Mars and Earth. Reaching the gas giant in 2030, the spacecraft will orbit Jupiter while flying by Europa dozens of times, dipping as close as 16 miles (25 kilometers) from the moon’s surface to gather data with its powerful suite of science instruments. The information will help scientists learn about the ocean beneath the moon’s icy shell, map Europa’s surface composition and geology, and hunt for any potential plumes of water vapor that may be venting from the crust.
“After over a decade of hard work and problem-solving, we’re so proud to show the nearly complete Europa Clipper spacecraft to the world,” said Evans. “As critical components came in from institutions across the globe, it’s been exciting to see parts become a greater whole. We can’t wait to get this spacecraft to the Jupiter system.”
At the event, a cutaway model showing the moon’s layers and a globe of the moon helped journalists learn why Europa is such an interesting object of study. On hand with the details were Project Staff Scientist and Assistant Science Systems Engineer Kate Craft from the Johns Hopkins Applied Physics Laboratory in Laurel, Maryland, and, from JPL, Project Scientist Robert Pappalardo, Deputy Project Scientist Bonnie Buratti, and Science Communications Lead Cynthia Phillips.
Beyond Earth, Europa is considered one of the most promising potentially habitable environments in our solar system. While Europa Clipper is not a life-detection mission, its primary science goal is to determine whether there are places below the moon’s icy surface that could support life.
When the main part of the spacecraft arrives at Kennedy Space Center in a few months, engineers will finish preparing Europa Clipper for launch on a SpaceX Falcon Heavy rocket, attaching its giant solar arrays and carefully tucking the spacecraft inside the capsule that rides on top of the rocket. Then Europa Clipper will be ready to begin its space odyssey.
More About the MissionEuropa Clipper’s three main science objectives are to determine the thickness of the moon’s icy shell and its surface interactions with the ocean below, to investigate its composition, and to characterize its geology. The mission’s detailed exploration of Europa will help scientists better understand the astrobiological potential for habitable worlds beyond our planet.
Managed by Caltech in Pasadena, California, JPL leads the development of the Europa Clipper mission in partnership with the Johns Hopkins Applied Physics Laboratory (APL) for NASA’s Science Mission Directorate in Washington. APL designed the main spacecraft body in collaboration with JPL and NASA’s Goddard Space Flight Center in Greenbelt, Maryland. The Planetary Missions Program Office at NASA’s Marshall Space Flight Center in Huntsville, Alabama, executes program management of the Europa Clipper mission.

NASA’s PACE Data on Ocean, Atmosphere, Climate Now Available
4 min read
Preparations for Next Moonwalk Simulations Underway (and Underwater) NASA’s PACE satellite’s Ocean Color Instrument (OCI) detects light across a hyperspectral range, which gives scientists new information to differentiate communities of phytoplankton – a unique ability of NASA’s newest Earth-observing satellite. This first image released from OCI identifies two different communities of these microscopic marine organisms in the ocean off the coast of South Africa on Feb. 28, 2024. The central panel of this image shows Synechococcus in pink and picoeukaryotes in green. The left panel of this image shows a natural color view of the ocean, and the right panel displays the concentration of chlorophyll-a, a photosynthetic pigment used to identify the presence of phytoplankton.Credit: NASANASA is now publicly distributing science-quality data from its newest Earth-observing satellite, providing first-of-their-kind measurements of ocean health, air quality, and the effects of a changing climate.
The Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) satellite was launched on Feb. 8, and has been put through several weeks of in-orbit testing of the spacecraft and instruments to ensure proper functioning and data quality. The mission is gathering data that the public now can access at https://pace.oceansciences.org/access_pace_data.htm.
PACE data will allow researchers to study microscopic life in the ocean and particles in the air, advancing the understanding of issues including fisheries health, harmful algal blooms, air pollution, and wildfire smoke. With PACE, scientists also can investigate how the ocean and atmosphere interact with each other and are affected by a changing climate.
“These stunning images are furthering NASA’s commitment to protect our home planet,” said NASA Administrator Bill Nelson. “PACE’s observations will give us a better understanding of how our oceans and waterways, and the tiny organisms that call them home, impact Earth. From coastal communities to fisheries, NASA is gathering critical climate data for all people.”
“First light from the PACE mission is a major milestone in our ongoing efforts to better understand our changing planet. Earth is a water planet, and yet we know more about the surface of the moon than we do our own oceans. PACE is one of several key missions – including SWOT and our upcoming NISAR mission – that are opening a new age of Earth science,” said Karen St. Germain, NASA Earth Science Division director.
PACE’s OCI instrument also collects data that can be used to study atmospheric conditions. The top three panels of this OCI image depicting dust from Northern Africa carried into the Mediterranean Sea, show data that scientists have been able to collect in the past using satellite instruments – true color images, aerosol optical depth, and the UV aerosol index. The bottom two images visualize novel pieces of data that will help scientists create more accurate climate models. Single-Scattering Albedo (SSA) tells the fraction of light scattered or absorbed, which will be used to improve climate models. Aerosol Layer Height tells how low to the ground or high in the atmosphere aerosols are, which aids in understanding air quality.Credit: NASA/UMBCThe satellite’s Ocean Color Instrument, which was built and managed by NASA’s Goddard Space Flight Center in Greenbelt, Maryland, observes the ocean, land, and atmosphere across a spectrum of ultraviolet, visible, and near infrared light. While previous ocean color satellites could only detect a handful of wavelengths, PACE is detecting more than 200 wavelengths. With this extensive spectral range, scientists can identify specific communities of phytoplankton. Different species play different roles in the ecosystem and carbon cycle — most are benign, but some are harmful to human health — so distinguishing phytoplankton communities is a key mission of the satellite.
PACE’s two multi-angle polarimeters, HARP2 and SPEXone, measure polarized light that has reflected off clouds and tiny particles in the atmosphere. These particles, known as aerosols, can range from dust to smoke to sea spray and more. The two polarimeters are complementary in their capabilities. SPEXone, built at the Netherlands Institute for Space Research (SRON) and Airbus Netherlands B.V., will view Earth in hyperspectral resolution – detecting all the colors of the rainbow – at five different viewing angles. HARP2, built at the University of Maryland, Baltimore County (UMBC), will observe four wavelengths of light, with 60 different viewing angles.
Early data from the SPEXone polarimeter instrument aboard PACE show aerosols in a diagonal swath over Japan on Mar. 16, 2024, and Ethiopia on Mar. 6, 2024. In the top two panels, lighter colors represent a higher fraction of polarized light. In the bottom panels, SPEXone data has been used to differentiate between fine aerosols, like smoke, and coarse aerosols, like dust and sea spray. SPEXone data can also measure how much aerosols are absorbing light from the Sun. Above Ethiopia, the data show mostly fine particles absorbing sunlight, which is typical for smoke from biomass burning. In Japan, there are also fine aerosols, but without the same absorption. This indicates urban pollution from Tokyo, blown toward the ocean and mixed with sea salt. The SPEXone polarization observations are displayed on a background true color image from another of PACE’s instruments, OCI.Credit: SRONWith these data, scientists will be able to measure cloud properties — which are important for understanding climate — and monitor, analyze, and identify atmospheric aerosols to better inform the public about air quality. Scientists will also be able to learn how aerosols interact with clouds and influence cloud formation, which is essential to creating accurate climate models.
Early images from PACE’s HARP2 polarimeter captured data on clouds over the west coast of South America on Mar. 11, 2024. The polarimetry data can be used to determine information about the cloud droplets that make up the cloudbow – a rainbow produced by sunlight reflected by cloud droplets instead of rain droplets. Scientists can learn how the clouds respond to man-made pollution and other aerosols and can measure the size of the cloud droplets with this polarimetry data.Credit: UMBC“We’ve been dreaming of PACE-like imagery for over two decades. It’s surreal to finally see the real thing,” said Jeremy Werdell, PACE project scientist at NASA Goddard. “The data from all three instruments are of such high quality that we can start distributing it publicly two months from launch, and I’m proud of our team for making that happen. These data will not only positively impact our everyday lives by informing on air quality and the health of aquatic ecosystems, but also change how we view our home planet over time.”
The PACE mission is managed by NASA Goddard, which also built and tested the spacecraft and the ocean color instrument. The Hyper-Angular Rainbow Polarimeter #2 (HARP2) was designed and built by the University of Maryland, Baltimore County, and the Spectro-polarimeter for Planetary Exploration (SPEXone) was developed and built by a Dutch consortium led by Netherlands Institute for Space Research, Airbus Defence, and Space Netherlands.

NASA’s SERT II: ‘A Genuine Space Success Story’
5 min read
Preparations for Next Moonwalk Simulations Underway (and Underwater) An illustration of the SERT II spacecraft, which was comprised of the Agena upper stage, the experimental thrusters and associated equipment, and two large solar arrays.Credit: NASA“A genuine space success story,” is how Experiments Manager William Kerslake described NASA’s second Space Electric Rocket Test (SERT II), the first long-duration operation of ion thrusters in space. SERT II provided researchers with data for years beyond its expected lifetime and was a rare example of an entire mission – including the launch, propulsion system, spacecraft, and control center – being handled by one organization: NASA’s Lewis Research Center in Cleveland (today, NASA Glenn).
The concept of electric propulsion thrusters dates back to the early 20th century, but because they must operate in a vacuum, there was no practical application for these systems until the space program decades later. In the late 1950s, researchers at NASA Lewis began investigating types of electric propulsion and analyzing missions that could use these systems. They produce low amounts of thrust by creating and accelerating small particles at high velocities, and over time, can accelerate spacecraft at very high rates of speed. Their ability to operate continuously for years at a time with little propellant makes them ideal for long-duration missions or keeping satellites in orbit.
This work was expanded in the early 1960s with the creation of Lewis’ Electromagnetic Propulsion Division and the construction of large vacuum facilities, including the Electric Propulsion and Power Laboratory (EPPL). Lewis engineer Harold Kaufman’s electron bombardment ion engine, which used liquid mercury as its propellant, was the most promising option. While Kaufman’s thruster was undergoing extensive testing in the EPPL tanks, Lewis engineers began developing a spacecraft to test the thruster. During the 50-minute suborbital SERT I flight on July 20, 1964, the Kaufman thruster became the first ion engine to operate in space.
In early 1968, the experimental portion of SERT II underwent six months of testing in Tank 5 at NASA Lewis Research Center’s (now, NASA Glenn’s) Electric Propulsion and Power Laboratory in conditions that simulated the temperatures and pressures it would encounter in space. The two thrusters can be seen in this photograph.Credit: NASA/ Paul RiedelLewis continued improving the thruster system, and in August 1966 received approval for SERT II. Researchers wanted to verify the thrusters could operate for longer durations in space, determine their effect on other spacecraft systems, and measure the degradation of solar arrays over time.
The center began simultaneous development of the SERT II ion thruster system and the spacecraft that would place it into orbit: a Thorad-Agena rocket. SERT II had two 15-centimeter diameter electron bombardment thrusters affixed to the back end and a 5-by-40 foot solar array, the largest ever flown by NASA at that time, at the other end.
After a series of tests in the EPPL, SERT II blasted off on February 3, 1970. Project Manager Raymond Rulis called the launch “one of the smoothest operations I’ve seen.” SERT II was placed into a circular polar orbit that provided its solar arrays with the continuous sunlight required to power its thrusters and electronic systems.
A Thorad-Agena rocket lifts off from Vandenberg Air Force Base on February 3, 1970, with the SERT II spacecraft. NASA Lewis Research Center (now, NASA Glenn) managed the Agena Program between 1962 and 1970, with SERT II being the last of the center’s 28 successful launches.Credit: NASAOn February 14, 1970, Lewis engineers activated the first thruster, beginning its six-month operational test. Three weeks later, operators shut the thruster down just before the vehicle passed through the path of a solar eclipse. It was restarted without issue afterwards and continued operation as the spacecraft encountered the eclipse a second time later that day.
The thruster operated successfully for five months until an electrical short in the grid caused it to fail on July 22, 1970. Two days later, the second thruster was activated. It operated smoothly for three-and-a-half months until a similar short occurred in mid-October. Though the SERT II thrusters failed to meet their six-month objectives, they did operate for extended periods, confirming data obtained in Lewis’ vacuum tanks.
The mission continued when Lewis engineers reactivated SERT II in 1973 to demonstrate cathode restarting, and the following year, they resolved an electrical short in one of the thrusters. During periods of intermittent sunlight, operators demonstrated restarting the thruster with less than an hour of power available. SERT II’s return to an orbit in continuous sunlight in 1979 provided Lewis researchers the opportunity to conduct over 500 restarts. They operated the thruster for 18,000 hours before the propellant ran out in the spring of 1981.
William Kerslake (seen in this 1981 photograph) and Louis Ignaczak managed the SERT II operations from a specially designed control center in NASA’s Lewis Research Center’s (now, NASA Glenn’s) 10-by 10-Foot Supersonic Wind Tunnel building. The control center allowed engineers to monitor the mission and send commands to the spacecraft through NASA’s satellite communication system. Credit: NASA/Daniel LaietyOver eleven years, SERT II provided data on hundreds of thruster restarts, restarts after shutdowns as long as 18 months, ion beam neutralization of one thruster by the other, and discovery of a new plasma thrust mode. SERT II also verified that thruster operation had no harmful impact on spacecraft and solar arrays.
Still, SERT II continued to be an asset to NASA researchers. In the late 1980s, Lewis engineers realized that an auxiliary experiment on SERT II that analyzed the effect of micrometeoroids on solar mirrors could be beneficial to research on solar dynamic systems to power space stations. During six months in sunlight in 1990, the Lewis team determined that after 20 years in orbit, there was no degradation of the solar mirror’s optical properties.
Many technological components of the SERT II thruster system were incorporated into subsequent generations of ion thrusters. By the time the mission was terminated, Lewis was already ground testing thrusters twice the size of those on SERT II. The center has continued to lead NASA’s electric propulsion efforts, developing an array of technologies, including the NEXT-C thrusters that powered the Deep Space 1 and Dawn spacecraft. In support of the agency’s Artemis missions, NASA Glenn recently tested the thrusters that will power Gateway, NASA’s future lunar space station.

Our goal is to ensure that our processes embrace everyone, irrespective of their background or identity. I act as the bridge, pulling together diverse perspectives and information to create a more inclusive work environment.
I’m also actively involved in two solicitations — one for Minority University Research and Education Project (MUREP) OCEAN related projects, and another focused on Data Science Equity, Access and Priority (DEAP). We collaborate with faculty to award research grants, reaching out to individuals who might not typically hear about these opportunities but possess the skills and potential to excel.
What path led you to this role?
My journey with NASA started in 2002, and I arrived at Goddard in 2020 after being part of the Office of STEM Engagement at headquarters in Washington. Embarking on my career in the government at the age of 16, I faced a unique and early entry into the professional world. Despite my youth, I embraced the opportunities presented to me and took on a series of diverse assignments within the government sector. This journey was marked by a steadfast commitment to the philosophy of “growing where I was planted.”
In practical terms, this philosophy implies a dedication to making the most of the current circumstances and roles, regardless of their initial nature or perceived limitations. Instead of constantly seeking new environments, I focused on developing my skills, gaining valuable experiences, and contributing meaningfully to each position I held. This approach allowed me to extract valuable lessons and skills from every assignment, fostering personal and professional growth in unexpected ways.
The belief in “growing where I was planted” also speaks to resilience and adaptability. Rather than succumbing to challenges or setbacks, I viewed them as opportunities to learn and adapt. This mindset not only helped me navigate the complexities of working in the government but also positioned me to thrive in a variety of roles over the years.
As a result of this philosophy, I built a foundation of skills, knowledge, and adaptability that eventually led me to my current role at Goddard. Each assignment, whether seemingly small or significant, played a crucial role in shaping my career trajectory and preparing me for the challenges and responsibilities I now undertake in supporting programs and initiatives at Goddard.
What’s the most exciting or interesting part of working at NASA?
Being in a position that involves interactions with celebrities has been one of the most enjoyable aspects of my work. It provides a unique glimpse into the individuals who contribute to TV programs, movies, and media that showcase NASA’s endeavors towards our society’s forward progression. During my early days, I had the fascinating role of booking meetings that involved notable figures, and although the interaction was swift, the experience of seeing them in person was truly thrilling.
While working in the administrator’s office at headquarters, I had the privilege of witnessing the arrival of news reporters, city mayors, congressmen and women, and astronauts who came to meet with the administrator. Sitting in anticipation, I played a behind-the-scenes role, having foreknowledge of their visits and assisting in the planning process. Although my involvement was indirect, the opportunity to be in proximity to these space explorers and others and to play a part in coordinating their interactions was both rewarding and awe-inspiring.
Shawnta Ball poses with a “Hidden Figures Way” street sign at NASA Headquarters in Washington.Shawnta BallI’ve had the privilege to meet and greet famous people and directly supported three astronaut-turned-supervisors. However, one standout memory involves meeting Nichelle Nichols, who played Uhura on “Star Trek,” at the final space shuttle launch. STS-135, the last flight of the orbiter Atlantis, lifted off from Launch Pad 39A at NASA’s Kennedy Space Center in Florida on July 8, 2011. I will always be grateful to Ms. Nichols for the real-life role she played at NASA, which was to recruit minority and female astronauts and personnel for the agency’s Space Shuttle Program.
The sheer thought of being in the company of someone of her stature and witnessing firsthand the intersection of entertainment and NASA’s mission left a lasting impression. These encounters not only added a layer of excitement to my role but also reinforced the significance of the work we do at NASA, captivating the attention of influential figures who contribute to sharing our stories with the world.

Michoud Site Recovery Team Receives NASA’s Silver Group Achievement AwardBy Heather Keller
The High Voltage Hurricane Ida Site Recovery Team at NASA’s Michoud Assembly Facility was awarded the agency’s Silver Group Achievement Award on March 18. The team of seven was recognized for “exemplary employee dedication and perseverance ensuring the safety of site, SLS (Space Launch System) hardware, and personnel” onsite post landfall of the category 4 storm.
Hurricane Ida made landfall in southeast Louisiana on Aug. 29, 2021, causing catastrophic failure of high voltage infrastructure and leaving most of the city of New Orleans without power for several weeks. Michoud received major damage from the storm’s 112 mph wind gusts and sustained winds of 80 mph. Immediately after landfall, the Michoud High Voltage Team methodically and safely energized the 6 MW emergency generator while procedurally transferring power to the facility’s east and west master substations. The transfer provided critical power to the rocket factory’s final assembly area while coordinating with the SLS Program and Boeing.

The team also provided power for lighting, allowing the Boeing teams to conduct critical inspections of flight hardware for damages.
The team also set up and provided emergency generator power for critical site infrastructure, such as the Coast Guard Exchange (CGX), which provided fuel for response and recovery personnel and other necessary supplies.
The High Voltage Team collaborated with Entergy New Orleans to determine a timeline for Michoud to accept line voltage from the site’s generating station and was successful in accepting power five days post-landfall. They systematically worked to safely bring additional loads online as prioritized and requested by Boeing and the SLS Program with more than 35 buildings receiving power approximately eight days post hurricane and allow site opening for tenant access.

Dr. Sterry: Be Aware of Increase in Alcohol Abuse Rates Post COVIDDear Marshall family,
April is Alcohol Awareness Month, and recent data indicate the rates of alcohol abuse and deaths resulting from it have risen dramatically over the past few years.
Very early during the COVID-19 pandemic it became apparent that sales of alcohol were increasing, and so it has been expected that the negative impacts related to this issue would increase as well. But I don’t think anyone anticipated just how much they would increase. I understand your first inclination might be to skip over this, but it’s a quick read, so please take a moment to consider the situation for the sake of your family, friends, and co-workers.
Data from 2020–2021, published by the Centers for Disease Control and Prevention, indicate that 178,000 people died in the U.S. from alcohol abuse and related health problems during that period. This represents a 29% increase from 2016–2017, when there were an estimated 138,000 deaths. Similarly disturbing, data published by the National Institute on Alcohol Abuse and Alcoholism indicate that rates of alcohol use disorder rose from 14.5 million adults in the U.S. in 2019 to 29.5 million in 2022.
Since a majority of adults in the U.S. drink alcoholic beverages on occasion, it is becoming even more important to be mindful of how to reduce the risks of negative impacts on our health, and on our lives, in general. The U.S. Department of Agriculture offers guidelines for alcohol consumption geared toward limiting those risks: no more than one standard drink per day for women, and no more than two standard drinks per day for men. While the difference in the numbers may seem unfair, they are based primarily upon body mass and metabolism rates.
What constitutes a “standard drink” depends upon what you’re drinking. For example, for beer, it is 12 fluid ounces, for wine, it is 5 fluid ounces, and for liquor, it is 1.5 fluid ounces. While being mindful of the number of drinks we’re consuming, it’s also important to keep in mind that even within any given category or type of drink, the percentage of alcohol can vary significantly from one product to another. For example, in Alabama, beer can contain up to 13.9% alcohol, and wine can contain up to 24%.
I have two requests of you today. First, please be mindful of how much you’re drinking, and be deliberate in reducing your risks, if needed. If you’d like to do a quick assessment of your drinking, an anonymous self-report test is available at https://auditscreen.org/check-your-drinking. Also, please consider sharing this information with any of your family members and friends that you think might be at risk for the health problems and other dangers associated with alcohol abuse.
If you’d like to get more information about alcohol abuse, and the dangers associated with it, a few good resources include:

NASA Achieves Milestone for Engines to Power Future Artemis MissionsNASA achieved a major milestone April 3 for production of new RS-25 engines to help power its Artemis campaign to the Moon and beyond with completion of a critical engine certification test series at NASA’s Stennis Space Center.
The 12-test series represents a key step for lead engines contractor Aerojet Rocketdyne, an L3Harris Technologies company, to build new RS-25 engines, using modern processes and manufacturing techniques, for NASA’s SLS (Space Launch System) rockets that will power future lunar missions, beginning with Artemis V.
NASA conducted a full-duration RS-25 hot fire April 3 on the Fred Haise Test Stand at the agency’s Stennis Space Center, achieving a major milestone for future Artemis flights of NASA’s SLS (Space Launch System) rocket. It marked the final test of a 12-test series to certify production of new RS-25 engines by lead contractor Aerojet Rocketdyne, an L3Harris Technologies company, to help power SLS on Artemis missions to the Moon and beyond, beginning with Artemis V.NASA/Danny Nowlin“The conclusion of the certification test series at NASA Stennis is just the beginning for the next generation of RS-25 engines that will help power human spaceflight for Artemis,” said Johnny Heflin, SLS liquid engines manager. “The newly produced engines on future SLS rockets will maintain the high reliability and safe flight operational legacy the RS-25 is known for while enabling more affordable high-performance engines for the next era of deep space exploration.”
Through Artemis, NASA will establish the foundation for long-term scientific exploration at the Moon; land the first woman, first person of color, and first international partner astronaut on the lunar surface; and prepare for human expeditions to Mars for the benefit of all.
Contributing to that effort, the NASA Stennis test team conducted a full-duration, 500-second hot fire to complete the 12-test series on developmental engine E0525, providing critical performance data for the final RS-25 design certification review. The April 3 hot fire completed a test series that began in October 2023.
RS-25 engines are evolved space shuttle main engines, upgraded with new components to produce the additional power needed to help launch NASA’s SLS rocket. The first four Artemis missions are using modified space shuttle main engines also tested at NASA Stennis. For each Artemis mission, four RS-25 engines, along with a pair of solid rocket boosters, power the SLS rocket, producing more than 8.8 million pounds of total combined thrust at liftoff.
“This was a critical test series, and credit goes to the entire test team for their dedication and unique skills that allowed us to meet the schedule and provide the needed performance data,” said Chip Ellis, project manager for RS-25 testing at NASA Stennis. “The tests conducted at NASA Stennis help ensure the safety of our astronauts and their future mission success. We are proud to be part of the Artemis mission.”
Crews transport RS-25 developmental engine E0525 to the Fred Haise Test Stand on Aug. 30, 2023, for the second and final certification test series.NASA/Danny NowlinThe E0525 developmental engine featured new key components – including a nozzle, hydraulic actuators, flex ducts, and turbopumps – that matched design features of those used during an initial certification test series completed at NASA Stennis last summer.
The two certification test series helped verify the new engine components meet all Artemis flight requirements moving forward. Aerojet Rocketdyne is using techniques such as 3D printing to produce new RS-25 engines more efficiently, while maintaining high performance and reliability. NASA has awarded the company contracts to provide 24 new engines, supporting SLS launches for Artemis V through Artemis IX.
“Successfully completing this rigorous test series is a testament to the outstanding work done by the team to design, implement and test this upgraded version of the RS-25 that reduces the cost by 30% from the space shuttle program,” said Mike Lauer, RS-25 program director at Aerojet Rocketdyne. “We tested the new RS-25 engines to the extreme limits of operation to ensure the engines can operate at a higher power level needed for SLS and complete the mission with margin.”
RS-25 Final Certification Test Series by the Numbers
All RS-25 engines are tested and proven flightworthy at NASA Stennis prior to use on Artemis missions. RS-25 tests at the center are conducted by a diverse team of operators from NASA, Aerojet Rocketdyne, and Syncom Space Services, prime contractor for site facilities and operations.
NASA’s Marshall Space Flight Center manages the SLS Program.
Agency Selects Companies to Advance Moon Mobility for Artemis MissionsNASA has selected Intuitive Machines, Lunar Outpost, and Venturi Astrolab to advance capabilities for a lunar terrain vehicle (LTV) that Artemis astronauts will use to travel around the lunar surface, conducting scientific research during the agency’s Artemis campaign at the Moon and preparing for human missions to Mars.
The awards leverage NASA’s expertise in developing and operating rovers to build commercial capabilities that support scientific discovery and long-term human exploration on the Moon. NASA intends to begin using the LTV for crewed operations during Artemis V.
An artist’s concept design of NASA’s lunar terrain vehicle.NASA“We look forward to the development of the Artemis generation lunar exploration vehicle to help us advance what we learn at the Moon,” said Vanessa Wyche, director of NASA’s Johnson Space Center. “This vehicle will greatly increase our astronauts’ ability to explore and conduct science on the lunar surface while also serving as a science platform between crewed missions.”
NASA will acquire the LTV as a service from industry. The indefinite-delivery/indefinite-quantity, milestone-based Lunar Terrain Vehicle Services contract with firm-fixed-price task orders has a combined maximum potential value of $4.6 billion for all awards.
Each provider will begin with a feasibility task order, which will be a year-long special study to develop a system that meets NASA’s requirements through the preliminary design maturity project phase. The agency will issue a subsequent request for task order proposal to eligible provider(s) for a demonstration mission to continue developing the LTV, deliver it to the surface of the Moon, and validate its performance and safety ahead of Artemis V. NASA anticipates making an award to only one provider for the demonstration. NASA will issue additional task orders to provide unpressurized rover capabilities for the agency’s moonwalking and scientific exploration needs through 2039.
The LTV will be able to handle the extreme conditions at the Moon’s South Pole and will feature advanced technologies for power management, autonomous driving, and state of the art communications and navigation systems. Crews will use the LTV to explore, transport scientific equipment, and collect samples of the lunar surface, much farther than they could on foot, enabling increased science returns.
Between Artemis missions, when crews are not on the Moon, the LTV will operate remotely to support NASA’s scientific objectives as needed. Outside those times, the provider will have the ability to use their LTV for commercial lunar surface activities unrelated to NASA missions.
“We will use the LTV to travel to locations we might not otherwise be able to reach on foot, increasing our ability to explore and make new scientific discoveries,” said Jacob Bleacher, chief exploration scientist in the Exploration Systems Development Mission Directorate at NASA Headquarters. “With the Artemis crewed missions, and during remote operations when there is not a crew on the surface, we are enabling science and discovery on the Moon year around.”
NASA provided technical requirements, capabilities, and safety standards needed for LTV development and operations, and the selected companies have agreed to meet the key agency requirements. The contract request for proposal required each provider to propose a solution to provide end-to-end services, including LTV development, delivery to the Moon, and execution of operations on the lunar surface.
Through Artemis, NASA will send astronauts – including the first woman, first person of color, and its first international partner astronaut – to explore the Moon for scientific discovery, technology evolution, economic benefits, and to build the foundation for crewed missions to Mars. Advanced rovers, along with the agency’s SLS (Space Launch System) rocket and Orion spacecraft, commercial human landing systems and next-generation spacesuits, and Gateway are NASA’s foundation for deep space exploration.
Hubble Peers at Pair of Closely Interacting GalaxiesAn image from the NASA/ESA Hubble Space Telescope features Arp 72, a very selective galaxy group that only includes two galaxies interacting due to gravity: NGC 5996 (the large spiral galaxy) and NGC 5994 (its smaller companion, in the lower left of the image).
This NASA/ESA Hubble Space Telescope image features Arp 72.ESA/Hubble & NASA, L. Galbany, J. Dalcanton, Dark Energy Survey/DOE/FNAL/DECam/CTIO/NOIRLab/NSF/AURABoth galaxies lie approximately 160 million light-years from Earth, and their cores are separated from each other by a distance of about 67,000 light-years. The distance between the galaxies at their closest points is even smaller, closer to 40,000 light-years.
While this might sound vast, in galactic separation terms it is quite close. For comparison, the distance between the Milky Way and its nearest independent galactic neighbor Andromeda is around 2.5 million light-years. Alternatively, the distance between the Milky Way and its largest and brightest satellite galaxy, the Large Magellanic Cloud (satellite galaxies orbit around another galaxy), is about 162,000 light-years.
Given this and the fact that NGC 5996 is comparable in size to the Milky Way, it is not surprising that NGC 5996 and NGC 5994 – separated by only about 40,000 light-years – are interacting with one another. In fact, the interaction likely distorted NGC 5996’s spiral shape. It also prompted the formation of the very long and faint tail of stars and gas curving away from NGC 5996, up to the top right of the image. This “tidal tail” is a common phenomenon that appears when galaxies closely interact and is visible in other Hubble images of interacting galaxies.
NASA, Japan Advance Space Cooperation, Sign Agreement for Lunar Rover
NASA Administrator Bill Nelson and Japan’s Minister of Education, Culture, Sports, Science and Technology (MEXT) Masahito Moriyama have signed an agreement to advance sustainable human exploration of the Moon.
Japan will design, develop, and operate a pressurized rover for crewed and uncrewed exploration on the Moon. NASA will provide the launch and delivery of the rover to the Moon as well as two opportunities for Japanese astronauts to travel to the lunar surface.
Today, President Biden and Prime Minister Kishida also announced, “a shared goal for a Japanese national to be the first non-American astronaut to land on the Moon on a future Artemis mission, assuming important benchmarks are achieved.”
The pressurized lunar rover is intended to enable astronauts to travel farther and work for longer periods on the lunar surface. The signing took place April 9 at NASA Headquarters in Washington. Along with Nelson and Moriyama, JAXA (Japan Aerospace Exploration Agency) President Hiroshi Yamakawa also participated in the signing.
“The quest for the stars is led by nations that explore the cosmos openly, in peace, and together. This is true for the United States and Japan under the leadership of President Biden and Prime Minister Kishida,” said Nelson. “America no longer will walk on the Moon alone. With this new rover, we will uncover groundbreaking discoveries on the lunar surface that will benefit humanity and inspire the Artemis Generation.”
An enclosed and pressurized rover will enable astronauts to travel farther and conduct science in geographically diverse areas by serving as a mobile habitat and laboratory for the astronauts to live and work for extended periods of time. It will be able to accommodate two astronauts for up to 30 days as they traverse the area near the lunar South Pole. NASA currently plans to use the pressurized rover on Artemis VII and subsequent missions over an approximate 10-year lifespan.
“It was an honor to sign the historic implementing arrangement that will be long remembered as the symbol of the new era of Japan-U.S. partnership for the lunar exploration,” said Moriyama. “Under the partnership stronger than ever, we will drive the initiative together with JAXA, including the development of the pressurized rover that vastly extends the exploration capability on the lunar surface, to realize the shared goal for Japanese and American astronauts to, together, explore the moon.”
The arrangement falls under the “Framework Agreement Between the Government of Japan and the Government of the United States of America for Cooperation in Space Exploration and Use of Outer Space, Including the Moon and Other Celestial Bodies, For Peaceful Purposes,” which was signed in January 2023 and recognizes the nations’ mutual interest in peaceful exploration.
The framework agreement facilitates a broad swath of joint activities between the countries, including space science, Earth science, space operations and exploration, aeronautical science and technology, space technology, space transportation, safety, and mission assurance, and much more. In addition to the agreement for lunar surface exploration, the partners will build on the framework agreement with future agreements for Japan’s participation in NASA’s Dragonfly mission and the Nancy Grace Roman Space Telescope. The U.S. and Japan also intend to collaborate on JAXA’s Next-generation Solar-observing Satellite, SOLAR-C, which will investigate the mysteries of solar atmospheres by conducting observations of ultraviolet radiation from the Sun.
“The pressurized rover will be a powerful contribution to the overall Artemis architecture as Japan and the U.S. go hand in hand with international and industry partners to the lunar surface and beyond,” said Yamakawa. “JAXA is ready to assist MEXT and push this forward with our science and technological expertise to establish sustainable human presence on the Moon.”
Under the Gateway Implementing Arrangement signed in 2022, NASA will also provide an opportunity for a Japanese astronaut to serve as a Gateway crew member on a future Artemis mission and Japan will provide Gateway’s environmental control and life support systems and cargo transportation.
Through Artemis, NASA will land the first woman, first person of color, and its first international partner astronaut on the Moon, make new scientific discoveries, and explore more of the lunar surface than ever before for the benefit of all.

More Than 36,000 Volunteers Helped Do NASA Eclipse Science
Clinton Lewis from New Harmony, IN/Western Kentucky University
Thank you for helping us out! Over 36,000 people helped do NASA Science during Monday’s total solar eclipse. Together, these volunteers submitted more than 60,000 vital pieces of eclipse data to NASA science projects.
More than 30,000 volunteers with the SunSketcher project pointed their smartphones toward the Sun and recorded pictures of Bailey’s beads, flashes of Sunlight coming through valleys on the moon. These pictures will reveal the size and shape of the Sun to high precision.
Volunteers with GLOBE Observer (GO) submitted more than 35,000 data points to the GO Eclipse, GO Clouds, and GO Landcover projects, taking eclipse data using their cell phones and sometimes thermometers. These data show the effect of the eclipse on our atmosphere.
Many more volunteers used specialized gear—DSLR cameras, telescopes, audiomoth recorders, and Ham Radio sets—taking data for the Dynamic Eclipse Broadcast Initiative, the Eclipse Megamovie project, Citizen CATE 2024, Eclipse Soundscapes, and the HamSCI project. These data will trace plumes and ejections of matter in the solar corona, track waves in the ionosphere, and reveal how animals, birds and insects reacted to the eclipse.
“I’m fascinated by the idea that the eclipse can affect the behavior of animals!” said one Eclipse Soundscapes volunteer. “I hope you all get a good data set and am still very excited to see the results! It was awesome!” said a SunSketcher volunteer.
Science is a methodical process and sometimes a slow process. Data are still arriving from cell phones and computers around the country. It will probably take months or even years for scientists to check and analyze the data, compare it with data on previous eclipses, and publish it in the refereed scientific literature.
But stay tuned as the Heliophysics Big Year continues! There will probably be some beautiful pictures coming out in the days and weeks to come thanks to your efforts.

Emma Friedman, an Office of Communications intern at NASA’s Langley Research Center in Hampton, Virginia, understood that the total solar eclipse on April 8th, 2024, was an out-of-this-world opportunity she couldn’t miss.
Equipped with the proper eye protection, I traveled over one thousand miles to Dallas, Texas, to be in the eclipse’s path of totality. As I got situated in a park near the city, I was excited—I’d read books and seen photos of what an eclipse looked like and knew what to expect, but I also knew that seeing it in person would be something greater than fiction. Slowly but surely, the Moon took more and more “bites” out of the sun, until I saw the last little peek of light before the darkness; this is known as the “diamond ring effect.”
As she waited for 100% totality during the 2024 total solar eclipse, Emma captured this image of crescent-shaped shadows cast by tree leaves. During an eclipse, light from the Sun passes through small gaps between tree leaves, creating a natural pinhole camera effect; images of the eclipse are then projected onto the surface below.NASA / Emma FriedmanBefore I had time to process any of it, the hairs on the back of my neck stood up. A silence fell across the park—even the birds stopped chirping—and I held my breath. All you could hear was the rustling of branches. What was a warm spring day was now a cold, dark dusk. It felt like the world had flipped on its head—first slowly, and then all at once. What the Sun had just seconds before lit was now a black void. The glow I saw around the Sun was its outer atmosphere, known as the corona. It was a moving sight, but why did I travel so far to experience it? Surely a viewing of a total eclipse was not in need of a plane ride.
It’s actually more complicated than simply waiting for the Moon to drift in front of the Sun. You have to be in the right place at the right time in a region called the “path of totality.”
The total solar eclipse will be visible along a narrow track stretching from Texas to Maine on April 8, 2024. A partial eclipse will be visible throughout all 48 contiguous U.S. states. Want to download this map and view other versions? Visit NASA’s Scientific Visualization Studio.NASA’s Scientific Visualization StudioAs a Maryland local, seeing a total solar eclipse from my home would be impossible during this eclipse. Despite eclipses being relatively common, it is a bit more challenging to see the Moon totally block out our Sun.
I spoke to Atmospheric Scientist and expert, Marilé Colón Robles, about the so-called “eclipse chasing” people like me took part in.
“Solar eclipses happen every eighteen months or so, so they are pretty common. To see a total solar eclipse is more challenging because a limited amount of the Earth’s surface is in the path of totality at any given time. Because the world is mostly made up of oceans, your chances of seeing a total eclipse from where you live is small. If, by chance, a total eclipse is happening near you, it’s best to travel to it.”
One team from NASA Langley did something similar by traveling to Houlton, Maine, to broadcast the eclipse in the path of totality. The broadcast showcases the moments before, during, and after the total solar eclipse. Another team of researchers from NASA Langley traveled to Fort Drum, N.Y., also located in the path of totality, to study changes in the weather during the total solar eclipse using a specially modified drone flying at 10,000 feet.
You can see my time lapse of the total solar eclipse below. Needless to say, the plane ride was worth it, and I was fortunate to enjoy one of the most cinematic and humbling phenomena that an Earthling can experience.

Winners of the student launch will be announced on Friday, June 7 during a virtual awards ceremony once all teams’ flight data has been verified.
About the Competition
Student Launch provides relevant, cost-effective research and development of rocket propulsion systems and reflects the goals of NASA’s Artemis campaign, which seeks to put the first woman and first person of color on the Moon.
Each year, the payload component changes to reflect current NASA missions. This year’s payload challenge is inspired by the Artemis missions.
Students will design a SAIL (STEMnaut Atmosphere Independent Lander) payload. It must deploy mid-air, safely return to the ground without using a parachute, and be reusable to launch the same day without repairs or modifications. The payload will contain a crew of STEMnauts, four non-living objects representing astronauts. Students will choose metrics to determine the endurance of the lander, considering acceptable descent and landing parameters.
Middle and high school teams can choose to attempt the lander payload or develop their own science or engineering experiment.
Eligible teams compete for prizes and awards and are scored in nearly a dozen categories including safety, vehicle design, social media presence, and science, technology, engineering, and math (STEM) engagement. Teams can also win the Altitude Award in each division based on how close they get to the altitude they projected their rockets would reach months in advance to launch day.
Marshall’s Office of STEM Engagement hosts Student Launch to encourage students to pursue careers in STEM through real-world experiences. Student Launch is a part of the agency’s Artemis Student Challenges – a variety of activities exposing students to the knowledge and technology required to achieve the goals of the Artemis missions.
In addition to the NASA Office of STEM Engagement’s Next Gen STEM project, NASA Space Operations Mission Directorate, Northrup Grumman, National Space Club Huntsville, American Institute of Aeronautics and Astronautics, National Association of Rocketry, Relativity Space and Bastion Technologies provide funding and leadership for the competition.

NASA Next-Generation Solar Sail Boom Technology Ready for Launch
Sailing through space might sound like something out of science fiction, but the concept is no longer limited to books or the big screen. In April, a next-generation solar sail technology – known as the Advanced Composite Solar Sail System – will launch aboard Rocket Lab’s Electron rocket from the company’s Launch Complex 1 in Māhia, New Zealand. The technology could advance future space travel and expand our understanding of our Sun and solar system.
Solar sails use the pressure of sunlight for propulsion, angling toward or away from the Sun so that photons bounce off the reflective sail to push a spacecraft. This eliminates heavy propulsion systems and could enable longer duration and lower-cost missions. Although mass is reduced, solar sails have been limited by the material and structure of the booms, which act much like a sailboat’s mast. But NASA is about to change the sailing game for the future.

The Advanced Composite Solar Sail System demonstration uses a twelve-unit (12U) CubeSat built by NanoAvionics to test a new composite boom made from flexible polymer and carbon fiber materials that are stiffer and lighter than previous boom designs. The mission’s primary objective is to successfully demonstrate new boom deployment, but once deployed, the team also hopes to prove the sail’s performance.
Like a sailboat turning to capture the wind, the solar sail can adjust its orbit by angling its sail. After evaluating the boom deployment, the mission will test a series of maneuvers to change the spacecraft’s orbit and gather data for potential future missions with even larger sails.
“Booms have tended to be either heavy and metallic or made of lightweight composite with a bulky design – neither of which work well for today’s small spacecraft. Solar sails need very large, stable, and lightweight booms that can fold down compactly,” said Keats Wilkie, the mission’s principal investigator at NASA’s Langley Research Center in Hampton, Virginia. “This sail’s booms are tube-shaped and can be squashed flat and rolled like a tape measure into a small package while offering all the advantages of composite materials, like less bending and flexing during temperature changes.”

When the composite booms and solar sail deploy in orbit, they will measure about 860 square feet (80 square meters) – about the size of six parking spots. Credit: NASA/Brandon TorresNASA/Brandon TorresAfter reaching its Sun-synchronous orbit, about 600 miles (1,000 kilometers) above Earth, the spacecraft will begin unrolling its composite booms, which span the diagonals of the polymer sail. After approximately 25 minutes the solar sail will fully deploy, measuring about 860 square feet (80 square meters) – about the size of six parking spots. Spacecraft-mounted cameras will capture the sail’s big moment, monitoring its shape and symmetry during deployment.
With its large sail, the spacecraft may be visible from Earth if the lighting conditions are just right. Once fully expanded and at the proper orientation, the sail’s reflective material will be as bright as Sirius, the brightest star in the night sky.
“Seven meters of the deployable booms can roll up into a shape that fits in your hand,” said Alan Rhodes, the mission’s lead systems engineer at NASA’s Ames Research Center in California’s Silicon Valley. “The hope is that the new technologies verified on this spacecraft will inspire others to use them in ways we haven’t even considered.”
This artist’s concept shows the Advanced Composite Solar Sail System spacecraft sailing in space using the energy of the Sun. Credit: NASA/Aero Animation/Ben Schweighart Enabling Future Solar SailsThrough NASA’s Small Spacecraft Technology program, successful deployment and operation of the solar sail’s lightweight composite booms will prove the capability and open the door to larger scale missions to the Moon, Mars, and beyond.
This boom design could potentially support future solar sails as large as 5,400 square feet (500 square meters), about the size of a basketball court, and technology resulting from the mission’s success could support sails of up to 21,500 square feet (2,000 square meters) – about half a soccer field.
“The Sun will continue burning for billions of years, so we have a limitless source of propulsion. Instead of launching massive fuel tanks for future missions, we can launch larger sails that use “fuel” already available,” said Rhodes. “We will demonstrate a system that uses this abundant resource to take those next giant steps in exploration and science.”
Because the sails use the power of the Sun, they can provide constant thrust to support missions that require unique vantage points, such as those that seek to understand our Sun and its impact on Earth. Solar sails have long been a desired capability for missions that could carry early warning systems for monitoring solar weather. Solar storms and coronal mass ejections can cause considerable damage on Earth, overloading power grids, disrupting radio communications, and affecting aircraft and spacecraft.
Composite booms might also have a future beyond solar sailing: the lightweight design and compact packing system could make them the perfect material for constructing habitats on the Moon and Mars, acting as framing structures for buildings or compact antenna poles to create a communications relay for astronauts exploring the lunar surface.
“This technology sparks the imagination, reimagining the whole idea of sailing and applying it to space travel,” said Rudy Aquilina, project manager of the solar sail mission at NASA Ames. “Demonstrating the abilities of solar sails and lightweight, composite booms is the next step in using this technology to inspire future missions.”
NASA Ames manages the Advanced Composite Solar Sail System project and designed and built the onboard camera diagnostic system. NASA Langley designed and built the deployable composite booms and solar sail system. NASA’s Small Spacecraft Technology (SST) program office based at NASA Ames and led by the agency’s Space Technology Mission Directorate (STMD), funds and manages the mission.

NASA Technology Helps Guard Against Lunar Dust
Defeating dust may be a small concern for most people on Earth, but for astronauts and spacecraft destined for the Moon or Mars, it is a significant hazard that must be mitigated. That’s why researchers at NASA’s Kennedy Space Center in Florida are seeking innovative ways to use Electrodynamic Dust Shield (EDS) technology.
Using transparent electrodes and electric fields, EDS technology can electrically lift and remove dust from a variety of surfaces for space applications ranging from thermal radiators, solar panels, and camera lenses to spacesuits, boots, and helmet visors. Controlling and removing the statically-charged dust will be critical to the success of Moon missions under the agency’s’ CLPS (Commercial Lunar Payload Services) initiative and Artemis campaign.
“For these CLPS and Artemis missions, dust exposure is a concern because the lunar surface is far different than what we’re used to here,” said Dr. Charles Buhler, lead research scientist at the Electrostatics and Surface Physics Laboratory at Kennedy. “Lunar regolith dust can get into gaskets and seals, into hatches, and even into habitats, which can pose a lot of issues for spacecraft and astronauts.”
Unlike dust particles on Earth, dust on the Moon’s surface is sharp and abrasive – like tiny shards of glass – because it hasn’t been exposed to weathering and elements like water and oxygen.
“Simply brushing lunar regolith across surfaces can make the problem worse because it’s also very electrostatically charged and highly insulating,” Buhler said.
Based on the Electric Curtain concept developed by NASA in 1967, EDS technology has been in development at Kennedy since 2004.
It first made its way to low Earth orbit aboard the NASA Materials International Space Station Experiment 11 mission in 2019. EDS technology was embedded in 12 different panels made of glass, polyimide, and prototype spacesuit fabric and sent to the International Space Station for testing in the vacuum of space.
Before making it to space, EDS had been predominantly tested in vacuum chambers that produced promising results of removing simulants and samples of lunar regolith, collected during NASA’s Apollo missions, from surfaces within a second.
Most recently, as part of Intuitive Machines’ first lunar lander mission, EDS technology was embedded in two lenses of EagleCam, a CubeSat camera system developed by students at Embry Riddle Aeronautical University in Daytona Beach, Florida. Following landing, the EagleCam instrument successfully deployed from Intuitive Machines’ Odysseus lander. The teams at Embry Riddle were unable to acquire images of the lander as they had hoped, but they were able to collect other data sets, including from the EDS technology.
Later this year, another EDS technology demonstration is slated to land on the Moon as part of NASA’s CLPS initiative mission with commercial partner Firefly Aerospace.
“The team has put in a tremendous amount of work and dedication. EDS is considered the leading technology and the best we have for the removal of dust for space applications,” Buhler said. “To fly as a dedicated payload on a mission to the Moon is very exciting.”
According to Buhler, EDS technology could be a first line of defense for establishing an extended human presence on the Moon with future Artemis missions.
From its applications with protecting tools, machinery, and spacesuits, the technology could potentially even help improve day-to-day tasks by being applied to small components like gaskets, seals, and hatches. This could save astronauts the hassle of traveling to the Moon with extra cleaning supplies.
“EDS technology can be used outside of a habitat to help clean surfaces like railings and floors, but it can be used inside as well,” Buhler said. “All of those applications are being evaluated and tested.”
