30 Years On, NASA’s Wind Is a Windfall for Studying our Neighborhood in Space
5 min read
30 Years On, NASA’s Wind Is a Windfall for Studying our Neighborhood in Space An artist’s concept of NASA’s Wind spacecraft outside of Earth’s magnetosphere. NASAPicture it: 1994. The first World Wide Web conference took place in Geneva, the first Chunnel train traveled under the English Channel, and just three years after the end of the Cold War, the first Russian instrument on a U.S. spacecraft launched into deep space from Cape Canaveral. The mission to study the solar wind, aptly named Wind, held promise for heliophysicists and astrophysicists around the world to investigate basic plasma processes in the solar wind barreling toward Earth — key information for helping us understand and potentially mitigate the space weather environment surrounding our home planet.
Thirty years later, Wind continues to deliver on that promise from about a million miles away at the first Earth-Sun Lagrange Point (L1). This location is gravitationally balanced between Earth and the Sun, providing excellent fuel economy that requires mere puffs of thrust to stay in place.
According to Lynn Wilson, who is the Wind project scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, fuel is only one indicator of Wind’s life expectancy, however. “Based on fuel alone, Wind can continue flying until 2074,” he said. “On the other hand, its ability to return data hinges on the last surviving digital tape recorder onboard.”
An artist’s concept shows a closeup of the Wind spacecraft. NASAWind launched with two digital tape recorders to record data from all the instruments on the spacecraft and provide reports on the spacecraft’s thermal conditions, orientation, and overall health. Each recorder has two tape decks, A and B, which Wilson affectionately refers to as “fancy eight-tracks.”
After six years of service, the first digital tape recorder failed in 2000 along with its two tape decks, forcing mission operators to switch to the second one. Tape Deck A on that one started showing signs of wear in 2016, so the mission operators now use Tape Deck B as the primary deck, with A as a backup.
“They built redundancy into the digital tape recorder system by building two of them, but you can never predict how technology will perform when it’s a million miles away, bathing in ionizing radiation,” said Wilson. “We’re fortunate that after 30 years, we still have two functioning tape decks.”
Wind launched on Nov. 1, 1994, on a Delta IV rocket from Cape Canaveral Air Force Station in Florida. NASA Bonus ScienceWhen Wind launched on Nov. 1, 1994, nobody could have possibly predicted that exactly 30 years later, NASA would be kicking off “Bonus Science” month in the Heliophysics Big Year. Beyond the mission’s incredible track record of mesmerizing discoveries about the solar wind — some detailed on its 25th anniversary — Wind continues to deliver with bonus science abound.
Opportunity and Collaborative DiscoveryAlong its circuitous journey to L1, Wind dipped in and out of Earth’s magnetosphere more than 65 times, capturing the largest whistler wave — a low-frequency radio wave racing across Earth’s magnetic field — ever recorded in Earth’s Van Allen radiation belts. Wind also traveled ahead of and behind Earth — about 150 times our planet’s diameter in both directions, informing potential future missions that would operate in those areas with extreme exposure to the solar wind. It even took a side quest to the Moon, cruising through the lunar wake, a shadow devoid of solar wind on the far side of the Moon.
Later, from its permanent home at L1, Wind was among several corroborating spacecraft that helped confirm what scientists believe is the brightest gamma-ray burst to occur since the dawn of human civilization. The burst, GRB 221009A, was first detected by NASA’s Fermi Gamma-ray Space Telescope in October 2022. Although not in its primary science objectives, Wind carries two bonus instruments designed to observe gamma-ray bursts that helped scientists confirm the burst’s origin in the Sagitta constellation.
Academic InspirationMore than 7,200 research papers have been published using Wind data, and the mission has supported more than 100 graduate and post-graduate degrees.
Wilson was one of those degree candidates. When Wind launched, Wilson was in sixth grade, on the football, baseball, and wrestling teams, with spare time spent playing video games and reading science fiction. He had a knack for science and considered becoming a medical doctor or an engineer before committing to his love of physics, which ultimately led to his current position as Wind’s project scientist. While pursuing his doctorate, he worked with Adam Szabo who was the Wind project scientist at NASA Goddard at the time and used Wind data to study interplanetary collisionless shock waves. Szabo eventually hired Wilson to work on the Wind mission team at Goddard.
Also in sixth grade at the time, Joe Westlake, NASA Heliophysics division director, was into soccer and music, and was a voracious reader consumed with Tolkein’s stories about Middle Earth. Now he leads the NASA office that manages Wind.
“It’s amazing to think that Lynn Wilson and I were in middle school, and the original mission designers and scientists have long since retired,” said Westlake. “When a mission makes it to 30 years, you can’t help but be inspired by the role it has played not only in scientific discovery, but in the careers of multiple generations of scientists.”

Station Nation: Meet Carlos Fontanot, the Imagery Manager Leaving a Legacy of Visual Storytelling
Born and raised in Mexico City, Carlos Fontanot has dedicated 34 years to NASA. He supports the International Space Station Mission Integration and Operations Office, ensuring that high-quality imagery enhances mission objectives and operations.
Fontanot is known for conceiving and leading the High Definition Earth Viewing (HDEV) project, which has brought stunning live visuals of Earth to millions around the globe. As he approaches his well-deserved retirement, we are excited to spotlight Fontanot’s remarkable career, celebrating his contributions to NASA and the lasting impact he has made on the agency’s mission to share the wonders of space.
Carlos Fontanot (left) receives the Great Minds in STEM Lifetime Achievement Award from Joel Montelbano, NASA at the Hispanic Engineer National Achievement Award Conference.What does your position entail?
Integrate all aspects of station imagery, from initial requirements to acquisition, processing, cataloging, archiving, and distribution of station imagery to multiple stakeholders, our clients.
How would you describe your job to family or friends who may not be as familiar with NASA?
I manage an array of television and digital still imagery cameras on the International Space Station. Each day we receive eight channels of high definition (HD) video and thousands of digital images that allow the ground team to see what the crew is doing in their daily lives and as part of scientific activities. In today’s age of social media and high-quality imagery, having these images is crucial for effectively conveying the station narrative.
I also chair the International Space Station’s Multilateral Imagery Working Group. Our team captures and processes the video and still images on a large server, where they are cataloged, archived, and distributed to our clients. Additionally, we are responsible for the photo and TV hardware aboard the space station and provide training to astronauts on how to use this equipment.
Carlos Fontanot with Liam Kennedy at the International Space Station Research and Development Conference.How do you feel the imagery and public affairs teams contribute to the overall mission of NASA?
Imagery is critical for communication in today’s visual environment. If people can’t see it, they won’t believe it! Effective communication through multimedia and pointed messaging is essential for securing continued support for NASA missions from both Congress and the public.
What was your path to NASA?
I was always interested in photography and film, so I studied radio, TV, and film in college. My first job after graduation was with a local TV station, and I also managed a media center for a multinational company. Then, I joined Johnson Space Center’s television and film division, where I managed space shuttle and institutional imagery.
Once at Johnson, I worked in the Office of Public Affairs as the audiovisual manager and served for two years as the public affairs officer in Moscow at the start of the International Space Station Program, including the launch of the first station crew.
What advice would you give to young individuals aspiring to work in the space industry or at NASA?
NASA is not just about astronauts, flight controllers, and engineers—there are countless disciplines and job opportunities here. Take imagery, for example: in today’s digital age, having the highest resolution imagery of our incredible orbiting laboratory environment and our home planet is essential.
For those aspiring to join the NASA team, I encourage you be open-minded and a team player. We need well-educated and talented individuals from diverse backgrounds across all disciplines to help us achieve our goals and explore the wonders of space.
Is there a space figure you’ve looked up to?
The space figure I will always remember and look up to is John Glenn. I had the fortune and privilege to meet him during his training. He was an extraordinary human being with incredibly high goals throughout his career.
I was assigned to escort John Glenn and the STS-95 crew on a two-week official visit to several European countries. John was by far the most inspiring and dedicated crew member that I’d ever met. He was always ready and willing to engage with dignitaries, politicians, leaders, journalists, and the public to share the NASA story and promote future programs to gain support from various governments and the public.
What do you love sharing about the International Space Station to general audiences?
I love sharing the wonders of life in space, especially the unique and breathtaking views of our planet Earth that can only be appreciated from space. I like to tell audiences about the observations and inspiration our astronauts share upon returning from their missions. I emphasize our thin and fragile atmosphere that sustains life as we know it, the beauty of Earth’s deserts, mountains, jungles, and oceans, and most importantly, the absence of borders. There’s always a profound realization that we are all human and that Earth belongs to all of us.
How has the technology for capturing images and video in space evolved over the years?
There was no digital imagery when I started my professional career. Photographs were taken on film that had to be processed in a dark room using chemicals to produce images. Video was recorded on two-inch magnetic tape at low resolution. We even flew film on our spacecraft that had to be brought back and processed on the ground.
Today, in the digital world, images can be streamed directly from our spacecraft and almost instantaneously shared with the entire globe. The evolution of technology has truly transformed how we capture and share the wonders of space!
Carlos Fontanot (left) sets up a NASA imagery exhibit in the Houston Downtown Tunnel System.What are some of the key projects you’ve worked on during your time at NASA? What have been your favorites?
During my time at NASA, I co-led the High Definition Earth Viewing (HDEV) project, which deployed four Earth-viewing cameras on the International Space Station, reaching over 318 million viewers globally. I also contributed to designing Johnson’s new PAO studio, collaborated on upgrading the space station’s downlink system from four standard-definition to eight high-definition channels, and advanced television technology, including the first HD and later UHD live downlinks from the station. These projects have allowed me to enhance NASA’s capacity for sharing space imagery with the world.
What are your plans for retirement, and how do you hope to stay connected to the space community?
I plan to travel across the U.S. in a travel trailer with my wife and dog and enjoying my hobbies I will now have time for, such as photography and spending quality time with my family.
Carlos and Pat Fontanot at the Grand Canyon South Rim in Arizona.How do you believe NASA’s imagery can continue to inspire future generations?
Astronaut John Young would come to the photo lab after every shuttle mission to review the film shot onboard. He would say, “A picture is worth a thousand words.” What can inspire more than a breathtaking image of a sunset captured from space or the aurora borealis over the polar regions?
What legacy do you hope to leave behind after your time at NASA?
I hope to leave behind a legacy of passion and dedication to acquiring and making pristine, high-resolution imagery from space available for the public to enjoy.
If you could have dinner with any astronaut, past or present, who would it be?
I would choose John Young. He flew during both the Apollo and shuttle eras, was an imagery expert, and had a deep understanding of the space station.

NASA Ames Recognizes Representative Eshoo for Her 32 Years of Service
On Oct. 29, NASA’s Ames Research Center in California’s Silicon Valley hosted a gathering to recognize Representative Anna G. Eshoo for her 32 years of distinguished public service and her enduring support for the agency. During the event, Dr. Eugene Tu, center director at Ames, presented the Congresswoman with the Pioneer plaque, a replica of the messages sent on the Pioneer 10 and 11 probes, which launched in 1972 and 1973 respectively.
I am Artemis: Lane Polak
Growing up, Lane Polak didn’t have much interest in space. Instead, he was busy writing stories, doodling, or riding his skateboard. He later dreamed of becoming an author but also considered stepping into the arena as an American Gladiator.
After earning a degree in communications with a minor in English from the University of Alabama in Huntsville, Polak chose to embrace his passion for storytelling and continued his path toward technical writing.
Fast forward 14 years and Polak is now a technical writer for NASA’s SLS (Space Launch System); a dream he never knew he had. In his current role at the agency’s Marshall Space Flight Center in Huntsville, Alabama, he is responsible for creating content that raises public awareness of NASA and specifically SLS. He also assists with outreach programs and supports exhibits, but it’s the opportunity to engage with the community, especially children, that he finds most rewarding.
“I believe a child’s development is one of the most amazing wonders in this world,” Polak said. “As a father, I love watching my two boys progress and learn new things, but I’ve always had a passion for helping children take their own giant leaps. That’s another great thing about creating – there is always a new idea to build on and explore.”
One way Polak has made his mark with the agency is through a series of children’s books designed to inspire the youngest members of the Artemis Generation. His first book, “Hooray for SLS!”, invites young readers on a journey to learn all about the SLS Moon rocket. With catchy writing and colorful illustrations, he captures the wonder of space exploration, making learning about the Artemis campaign both fun and engaging. It’s a celebration of curiosity and adventure, showing children just how exciting the journey to the Moon and Mars can be.
Working with NASA has transformed Polak’s perspective on collaboration and the power of storytelling in science. “After just a few months at NASA, I found myself completely captivated by space and the incredible projects and opportunities unfolding daily,” he said. “Being part of the Artemis Generation isn’t just a job for me; it’s a privilege. I have the opportunity to inspire future generations while contributing to humanity’s quest for deep space exploration. One of the many things my position allows me to do is help others see the scale of this amazing agency, all the work people are doing, and that there truly is a place for anyone here.”
Outside of work, Polak stays busy coaching youth sports, mountain biking, and spending quality time with his family. He and his wife Emily also enjoy buying and selling vintage clothing. Whether it’s creating new stories for kids or finding the next great idea to explore, he embraces the endless possibilities of creation.
What’s Up: November 2024 Skywatching Tips from NASA
Download the video
See the Moon Hide a Bright Star
In the early morning hours of November 27, catch a rare lunar occultation of Spica visible from parts of the U.S. and Canada.
Skywatching Highlights- All month – Planet visibility report: Saturn shines in the south most of the night, Jupiter rises in the early evening alongside Taurus and Orion, while Mars trails a couple of hours behind, visible high in the early morning sky.
- November 4 – Slim crescent Moon pairs with Venus. Enjoy a beautiful sight just after sunset as the Moon and Venus meet up in the southwestern sky.
- November 10 – Saturn & the Moon. The ringed planet has a close pairing with the Moon tonight (perfect for binoculars)
- November 27 – Lunar occultation of Spica. Early risers in the eastern U.S. and Canada can catch the Moon passing in front of Spica this morning, briefly hiding the bright star from view.
What’s Up for November?
When to look for Saturn, Jupiter, and Mars this month, a NASA spacecraft swings by Venus on its way to the Sun, and the tricky business of seeing the Moon hide a bright star. And stick around until the end for photos of highlights from last month’s skies.
Saturn is visible toward the south for most of the night. For observers in the Americas, it has a close meetup with the Moon on the 10th, when the pair will appear less than a degree apart just after dark, making for a great sight through binoculars. Check the sky again around midnight, and you’ll see the Moon has visibly shifted a couple of degrees west of Saturn, showing evidence of the Moon’s orbital motion in just a few hours.
In late 2024, Jupiter could be found high overhead as dawn approached with the bright stars of Taurus and Orion. (Jupiter is the bright object at top, right of center.) NASA/Preston DychesJupiter is rising in the east early in the night, together with the bright stars of the constellations Taurus and Orion, and working its way across the sky by dawn. By the end of November, it’s rising just as the sky is getting dark. Mars follows behind Jupiter, rising about three hours after the giant planet.
As in October, early risers will find the Red Planet high overhead in the morning sky before dawn. In the evening sky, Venus is low in the southwest following sunset throughout the month of November. It’s blazing bright and unmistakable if you find a relatively unobstructed view. It appears much higher in the sky for those in the Southern Hemisphere, who’ll also be able to easily observe Mercury after sunset this month. And on the 4th, a slim crescent Moon will appear just below Venus for a beautiful pairing as the glow of sunset fades.
Now, staying with Venus, one of NASA’s intrepid solar system explorers is headed for a close encounter with this Earth-sized hothouse of a planet on November 6th. Parker Solar Probe studies our planet’s nearest star, the Sun. Its mission is to trace the flow of energy that heats the Sun’s outer atmosphere and accelerates the million-mile-per-hour stream of particles it emits. It makes its measurements from super close to the Sun, within the region where all the action happens. To do this, the spacecraft was designed to fly within just 4 million miles of the Sun’s surface, which is 10 times closer than the orbit of the closest planet, Mercury. No other spacecraft has ever gotten this close to the Sun before. In the six years since its launch, the spacecraft has made a bunch of approaches to the Sun, using flybys of the planet Venus to shape its orbit. The November 6th flyby is the final such maneuver, intended to send the spacecraft toward its three closest-ever solar approaches, starting on December 24th. During this last Venus flyby, the mission will capture images of the planet. Previous views returned by Parker showed that the spacecraft could actually see features of the Venusian surface through its dense cloud cover. So look out for Venus in the evening sky, as the brilliant planet helps a craft from Earth to touch the face of the Sun.
In the couple of hours before sunrise on November 27th, skywatchers in the eastern half of the U.S. and Canada will have the chance to witness an occultation – an event where the Moon passes in front of, and temporarily hides, a bright star – in this case Spica. Observers in other parts of the world will see the Moon pass extremely close to Spica, but won’t see it cover up the star. This occultation is one of a series that began in June and will continue monthly through late next year. These happen as the Moon’s orbit slowly shifts northward and southward across the sky, and every so often, its path crosses in front of Spica monthly for a time. But each occultation is only visible from a small portion of Earth. For example, while this November event favors North American viewers, South American observers will get their chance next April. For U.S. skywatchers, this November occultation is the last good opportunity in this series to see the Moon occult Spica until 2032, when a new series of monthly occultations will begin for locations across the globe. Now, if you miss this event, don’t worry!
The Moon also passes in front of three other bright stars from time to time. This means that no matter where you’re located, you’ll have the opportunity before too long to witness the impressive sight of a bright star briefly disappearing behind the Moon.
Watch our video for views of what some of the highlights we told you about in last month’s video actually looked like.

In the 1997 movie “Contact,” adapted from Carl Sagan’s 1985 novel, the lead character scientist Ellie Arroway (played by actor Jodi Foster) takes a space-alien-built wormhole ride to the star Vega. She emerges inside a snowstorm of debris encircling the star — but no obvious planets are visible.
It looks like the filmmakers got it right.
A team of astronomers at the University of Arizona, Tucson used NASA’s Hubble and James Webb space telescopes for an unprecedented in-depth look at the nearly 100-billion-mile-diameter debris disk encircling Vega. “Between the Hubble and Webb telescopes, you get this very clear view of Vega. It’s a mysterious system because it’s unlike other circumstellar disks we’ve looked at,” said Andras Gáspár of the University of Arizona, a member of the research team. “The Vega disk is smooth, ridiculously smooth.”
The big surprise to the research team is that there is no obvious evidence for one or more large planets plowing through the face-on disk like snow tractors. “It’s making us rethink the range and variety among exoplanet systems,” said Kate Su of the University of Arizona, lead author of the paper presenting the Webb findings.

Hubble detects reflected light from dust that is the size of smoke particles largely in a halo on the periphery of the disk. The disk is very smooth, with no evidence of embedded large planets. The black spot at the center blocks out the bright glow of the hot young star.[right] The James Webb Space Telescope resolves the glow of warm dust in a disk halo, at 23 billion miles out. The outer disk (analogous to the solar system’s Kuiper Belt) extends from 7 billion miles to 15 billion miles. The inner disk extends from the inner edge of the outer disk down to close proximity to the star. There is a notable dip in surface brightness of the inner disk from approximately 3.7 to 7.2 billion miles. The black spot at the center is due to lack of data from saturation.

Webb sees the infrared glow from a disk of particles the size of sand swirling around the sizzling blue-white star that is 40 times brighter than our Sun. Hubble captures an outer halo of this disk, with particles no bigger than the consistency of smoke that are reflecting starlight.
The distribution of dust in the Vega debris disk is layered because the pressure of starlight pushes out the smaller grains faster than larger grains. “Different types of physics will locate different-sized particles at different locations,” said Schuyler Wolff of the University of Arizona team, lead author of the paper presenting the Hubble findings. “The fact that we’re seeing dust particle sizes sorted out can help us understand the underlying dynamics in circumstellar disks.”
The Vega disk does have a subtle gap, around 60 AU (astronomical units) from the star (twice the distance of Neptune from the Sun), but otherwise is very smooth all the way in until it is lost in the glare of the star. This shows that there are no planets down at least to Neptune-mass circulating in large orbits, as in our solar system, say the researchers.

“We’re seeing in detail how much variety there is among circumstellar disks, and how that variety is tied into the underlying planetary systems. We’re finding a lot out about the planetary systems — even when we can’t see what might be hidden planets,” added Su. “There’s still a lot of unknowns in the planet-formation process, and I think these new observations of Vega are going to help constrain models of planet formation.”
Disk DiversityNewly forming stars accrete material from a disk of dust and gas that is the flattened remnant of the cloud from which they are forming. In the mid-1990s Hubble found disks around many newly forming stars. The disks are likely sites of planet formation, migration, and sometimes destruction. Fully matured stars like Vega have dusty disks enriched by ongoing “bumper car” collisions among orbiting asteroids and debris from evaporating comets. These are primordial bodies that can survive up to the present 450-million-year age of Vega (our Sun is approximately ten times older than Vega). Dust within our solar system (seen as the Zodiacal light) is also replenished by minor bodies ejecting dust at a rate of about 10 tons per second. This dust is shoved around by planets. This provides a strategy for detecting planets around other stars without seeing them directly – just by witnessing the effects they have on the dust.
“Vega continues to be unusual,” said Wolff. “The architecture of the Vega system is markedly different from our own solar system where giant planets like Jupiter and Saturn are keeping the dust from spreading the way it does with Vega.”

For comparison, there is a nearby star, Fomalhaut, which is about the same distance, age and temperature as Vega. But Fomalhaut’s circumstellar architecture is greatly different from Vega’s. Fomalhaut has three nested debris belts.
Planets are suggested as shepherding bodies around Fomalhaut that gravitationally constrict the dust into rings, though no planets have been positively identified yet. “Given the physical similarity between the stars of Vega and Fomalhaut, why does Fomalhaut seem to have been able to form planets and Vega didn’t?” said team member George Rieke of the University of Arizona, a member of the research team. “What’s the difference? Did the circumstellar environment, or the star itself, create that difference? What’s puzzling is that the same physics is at work in both,” added Wolff.
First Clue to Possible Planetary Construction YardsLocated in the summer constellation Lyra, Vega is one of the brightest stars in the northern sky. Vega is legendary because it offered the first evidence for material orbiting a star — presumably the stuff for making planets — as potential abodes of life. This was first hypothesized by Immanuel Kant in 1775. But it took over 200 years before the first observational evidence was collected in 1984. A puzzling excess of infrared light from warm dust was detected by NASA’s IRAS (Infrared Astronomy Satellite). It was interpreted as a shell or disk of dust extending twice the orbital radius of Pluto from the star.
In 2005, NASA’s infrared Spitzer Space Telescope mapped out a ring of dust around Vega. This was further confirmed by observations using submillimeter telescopes including Caltech’s Submillimeter Observatory on Mauna Kea, Hawaii, and also the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile, and ESA’s (European Space Agency’s) Herschel Space Telescope, but none of these telescopes could see much detail. “The Hubble and Webb observations together provide so much more detail that they are telling us something completely new about the Vega system that nobody knew before,” said Rieke.
Two papers (Wolff et al. and Su et. al.) from the Arizona team will be published in The Astrophysical Journal.
The James Webb Space Telescope is the world’s premier space science observatory. Webb is solving mysteries in our solar system, looking beyond to distant worlds around other stars, and probing the mysterious structures and origins of our universe and our place in it. Webb is an international program led by NASA with its partners, ESA (European Space Agency) and CSA (Canadian Space Agency).
The Hubble Space Telescope has been operating for over three decades and continues to make ground-breaking discoveries that shape our fundamental understanding of the universe. Hubble is a project of international cooperation between NASA and ESA (European Space Agency). NASA’s Goddard Space Flight Center in Greenbelt, Maryland, manages the telescope and mission operations. Lockheed Martin Space, based in Denver, Colorado, also supports mission operations at Goddard. The Space Telescope Science Institute in Baltimore, Maryland, which is operated by the Association of Universities for Research in Astronomy, conducts Hubble science operations for NASA.

“Discipline is one of the things that they instill within you [in the military.] All the way starting in boot camp, [the goal] is doing the right thing when no one is looking. Integrity.
“Whenever you’re in boot camp, they always say, ‘it’s too easy.’ It’s just too easy to follow the rules, read the book, read the regulations, and that’s probably why I enjoy contracting. I like reading the regulations and following the regulations.

International SWOT Satellite Spots Planet-Rumbling Greenland Tsunami
4 min read
Preparations for Next Moonwalk Simulations Underway (and Underwater) A SWOT data visualization shows water on the northern side of Greenland’s Dickson Fjord at higher levels than on the southern side on Sept. 17, 2023. A huge rockslide into the fjord the previous day led to a tsunami lasting nine days that caused seismic rumbling around the world. NASA Earth ObservatoryData from space shows water tilting up toward the north side of the Dickson Fjord as it sloshed from south to north and back every 90 seconds for nine days after a 2023 rockslide.
The international Surface Water and Ocean Topography (SWOT) satellite mission, a collaboration between NASA and France’s CNES (Centre National d’Études Spatiales), detected the unique contours of a tsunami that sloshed within the steep walls of a fjord in Greenland in September 2023. Triggered by a massive rockslide, the tsunami generated a seismic rumble that reverberated around the world for nine days. An international research team that included seismologists, geophysicists, and oceanographers recently reported on the event after a year of analyzing data.
The SWOT satellite collected water elevation measurements in Dickson Fjord on Sept. 17, 2023, the day after the initial rockslide and tsunami. The data was compared with measurements made under normal conditions a few weeks prior, on Aug. 6, 2023.
In the data visualization (above), colors toward the red end of the scale indicate higher water levels, and blue colors indicate lower-than-normal levels. The data suggests that water levels at some points along the north side of the fjord were as much as 4 feet (1.2 meters) higher than on the south.
“SWOT happened to fly over at a time when the water had piled up pretty high against the north wall of the fjord,” said Josh Willis, a sea level researcher at NASA’s Jet Propulsion Laboratory in Southern California. “Seeing the shape of the wave — that’s something we could never do before SWOT.”
In a paper published recently in Science, researchers traced a seismic signal back to a tsunami that began when more than 880 million cubic feet of rock and ice (25 million cubic meters) fell into Dickson Fjord. Part of a network of channels on Greenland’s eastern coast, the fjord is about 1,772 feet (540 meters) deep and 1.7 miles (2.7 kilometers) wide, with walls taller than 6,000 feet (1,830 meters).
Far from the open ocean, in a confined space, the energy of the tsunami’s motion had limited opportunity to dissipate, so the wave moved back and forth about every 90 seconds for nine days. It caused tremors recorded on seismic instruments thousands of miles away.
From about 560 miles (900 kilometers) above, SWOT uses its sophisticated Ka-band Radar Interferometer (KaRIn) instrument to measure the height of nearly all water on Earth’s surface, including the ocean and freshwater lakes, reservoirs, and rivers.
“This observation also shows SWOT’s ability to monitor hazards, potentially helping in disaster preparedness and risk reduction,” said SWOT program scientist Nadya Vinogradova Shiffer at NASA Headquarters in Washington.
It can also see into fjords, as it turns out.
“The KaRIn radar’s resolution was fine enough to make observations between the relatively narrow walls of the fjord,” said Lee-Lueng Fu, the SWOT project scientist. “The footprint of the conventional altimeters used to measure ocean height is too large to resolve such a small body of water.”
More About SWOTLaunched in December 2022 from Vandenberg Space Force Base in California, SWOT is now in its operations phase, collecting data that will be used for research and other purposes.
The SWOT satellite was jointly developed by NASA and CNES, with contributions from the Canadian Space Agency (CSA) and the UK Space Agency. NASA’s Jet Propulsion Laboratory, managed for the agency by Caltech in Pasadena, California, leads the U.S. component of the project. For the flight system payload, NASA provided the KaRIn instrument, a GPS science receiver, a laser retroreflector, a two-beam microwave radiometer, and NASA instrument operations. CNES provided the Doppler Orbitography and Radioposition Integrated by Satellite (DORIS) system, the dual frequency Poseidon altimeter (developed by Thales Alenia Space), the KaRIn radio-frequency subsystem (together with Thales Alenia Space and with support from the UK Space Agency), the satellite platform, and ground operations. CSA provided the KaRIn high-power transmitter assembly. NASA provided the launch vehicle and the agency’s Launch Services Program, based at Kennedy Space Center in Florida, managed the associated launch services.

We Are All Made of Cells: Space and the Immune System
Malcolm O’Malley and his mom sat nervously in the doctor’s office awaiting the results of his bloodwork. This was no ordinary check-up. In fact, this appointment was more urgent and important than the SATs the seventeen-year-old, college hopeful had spent months preparing for and was now missing in order to understand his symptoms.
But when the doctor shared the results – he had off-the-charts levels of antibodies making him deathly allergic to shellfish – O’Malley realized he had more questions than answers. Like: Why is my immune system doing this? How is it working? Why is it reacting so severely and so suddenly (he’d enjoyed shrimp less than a year ago)? And why does the only treatment – an injection of epinephrine – have nothing to do with the immune system, when allergies appear to be an immune system problem? Years later, O’Malley would look to answer some of these questions while interning in the Space Biosciences Research Branch at NASA’s Ames Research Center in California’s Silicon Valley.
“Anaphylaxis is super deadly and the only treatment for it is epinephrine; and I remember thinking, ‘how is this the best we have?’ because epinephrine does not actually treat the immune system at all – it’s just adrenaline,” said O’Malley, who recently returned to his studies as a Ph.D. student of Biomedical Engineering at the University of Virginia (UVA) in Charlottesville. “And there’s a thousand side effects, like heart attacks and stroke – I remember thinking ‘these are worse than the allergy!’”
O’Malley’s curiosity and desire to better understand the mechanisms and connections between what triggers different immune system reactions combined with his interest in integrating datasets into biological insights inspired him to shift his major from computer science to biomedical engineering as an undergraduate student. With his recent allergy diagnosis and a lifelong connection to his aunt who worked at the UVA Heart and Vascular Center, O’Malley began to build a bridge between the immune system and heart health. By the time he was a senior in college, he had joined the Cardiac Systems Biology Lab, and had chosen to focus his capstone project on better understanding the role of neutrophils, a specific type of immune cell making up 50 to 70% of the immune system, that are involved in cardiac inflammation in high blood pressure and after heart attacks.

Image courtesy of Drs. Joseph Wu, Dilip Thomas and Xu Cao, Stanford Cardiovascular Institute“The immune system is involved in everything,” O’Malley says. “Anytime there’s an injury – a paper cut, a heart attack, you’re sick – the immune system is going to be the first to respond; and neutrophils are the first responders.”
O’Malley’s work to determine what regulates the immune system’s interrelated responses – like how one cell could affect other cells or immune processes downstream – provided a unique opportunity for him to support multiple interdisciplinary NASA biological and physical sciences research projects during his 10-week internship at NASA Ames over the summer of 2024. O’Malley applied machine learning techniques to the large datasets the researchers were using from experiments and specimens collected over many years to help identify possible causes of inflammation seen in the heart, brain, and blood, as well as changes seen in bones, metabolism, the immune system, and more when humans or other model organisms are exposed to decreased gravity, social isolation, and increased radiation. These areas are of keen interest to NASA due to the risks to human health inherent in space exploration and the agency’s plans to send humans on long-duration missions to the Moon, Mars, and beyond.
“It’s exciting that we just never know what’s going to happen, how the immune system is going to react until it’s already been activated or challenged in some way,” said O’Malley. “I’m particularly interested in the adaptive immune system because it’s always evolving to meet new challenges; whether it’s a pandemic-level virus, bacteria or something on a mission to Mars, our bodies are going to have some kind of adaptive immune response.”
During his NASA internship, O’Malley applied a statistical analysis techniques to plot and make more sense of the massive amounts of life sciences data. From there, researchers could find out which proteins, out of hundreds, or attributes – like differences in sex – are related to which behaviors or outcomes. For example, through O’Malley’s analysis, researchers were able to better pinpoint the proteins involved in inflammation of the brain that may play a protective role in spatial memory and motor control during and after exposure to radiation – and how we might be able to prevent or mitigate those impacts during future space missions and even here on Earth.

Former NASA Intern
“I had this moment where I realized that since my internship supports NASA’s Human Research Program that means the work I’m doing directly applies to Artemis, which is sending the first woman and person of color to the Moon,” reflected O’Malley. “As someone who’s both black and white, representation is important to me. It’s inspiring to think there will be people like me on the Moon – and that I’m playing a role in making this happen.”
Artist conception of a future Artemis Base Camp on the lunar surface NASAWhen O’Malley wasn’t exploring the mysteries of the immune system for the benefit of all at NASA Ames, he taught himself how to ride a bike and started to surf in the nearby waters of the Pacific Ocean. O’Malley considers Palmyra, Virginia, his hometown and he enjoys playing sports – especially volleyball, water polo, and tennis – reading science fiction and giving guest lectures to local high school students hoping to spark their curiosity.
O’Malley’s vision for the future of biomedical engineering reflects his passion for innovation. “I believe that by harnessing the unique immune properties of other species, we can achieve groundbreaking advancements in limb regeneration, revolutionize cancer therapy, and develop potent antimicrobials that are considered science fiction today,” he said.
Witch Nebula Casts Starry Spell
This 2013 image taken by NASA’s Wide-Field Infrared Survey Explorer, or WISE, captures a nebula that looks like a witch screaming. Perhaps that imagined scream is a creation spell, for the Witch Hat nebula’s billowy clouds are a star nursery. We can see these clouds thanks to massive stars lighting them up; dust in the cloud is being hit with starlight, causing it to glow with infrared light, which was picked up by WISE’s detectors.
WISE launched to near-Earth orbit on Dec. 14, 2009, and surveyed the full sky in four infrared wavelength bands until the frozen hydrogen cooling the telescope was depleted in September 2010. The spacecraft was placed into hibernation in February 2011, having completed its primary astrophysics mission.
In late 2013, the spacecraft was resurrected – no incantation needed – when NASA’s Planetary Science Division gave it a new mission and a new name: NEOWISE. The spacecraft began helping NASA identify and describe near-Earth objects (NEOs). NEOs are comets and asteroids that have been nudged into orbits that allow them to enter Earth’s neighborhood. NEOWISE was decommissioned Aug. 8, 2024, and placed into hibernation for the last time, ending its career as an active asteroid hunter.

Halloween on the International Space Station
Although no ghouls or goblins or trick-or-treaters come knocking at the International Space Station’s front hatch, crew members aboard the orbiting facility still like to get in the Halloween spirit. Whether individually or as an entire crew, they dress up in sometimes spooky, sometimes scary, but always creative costumes, often designed from materials available aboard the space station. Please enjoy the following scenes from Halloweens past even as we anticipate the costumes of the future.

In October 2021, Crew-3 NASA astronauts Raja J. Chari, Thomas H. Marshburn, Kayla S. Barron, and Matthias J. Maurer of the European Space Agency (ESA), had some undisclosed plans for when they reached the space station just before Halloween. However, bad weather at NASA’s Kennedy Space Center in Florida thwarted those super-secret spooky Halloween plans, delaying their launch until Nov. 11. Undeterred, Expedition 66 crewmembers who awaited them aboard the station held their own Halloween shenanigans. ESA astronaut Thomas G. Pesquet posted on social media that “Strange things were happening on ISS for Halloween. Aki rising from the dead (or is it from our observation window?),” referring to fellow crew member Akihiko Hoshide of the Japan Aerospace Exploration Agency.

Why NASA’s SPHEREx Mission Will Make ‘Most Colorful’ Cosmic Map Ever
6 min read
Preparations for Next Moonwalk Simulations Underway (and Underwater) NASA’s SPHEREx observatory undergoes integration and testing at BAE Systems in Boulder, Colorado, in April 2024. The space telescope will use a technique called spectroscopy across the entire sky, capturing the universe in more than 100 colors. BAE SystemsThe space telescope will detect over 100 colors from hundreds of millions of stars and galaxies. Here’s what astronomers will do with all that color.
NASA’s SPHEREx mission won’t be the first space telescope to observe hundreds of millions of stars and galaxies when it launches no later than April 2025, but it will be the first to observe them in 102 colors. Although these colors aren’t visible to the human eye because they’re in the infrared range, scientists will use them to learn about topics that range from the physics that governed the universe less than a second after its birth to the origins of water on planets like Earth.
“We are the first mission to look at the whole sky in so many colors,” said SPHEREx Principal Investigator Jamie Bock, who is based jointly at NASA’s Jet Propulsion Laboratory and Caltech, both in Southern California. “Whenever astronomers look at the sky in a new way, we can expect discoveries.”
Short for Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer, SPHEREx will collect infrared light, which has wavelengths slightly longer than what the human eye can detect. The telescope will use a technique called spectroscopy to take the light from hundreds of millions of stars and galaxies and separate it into individual colors, the way a prism transforms sunlight into a rainbow. This color breakdown can reveal various properties of an object, including its composition and its distance from Earth.
NASA’s SPHEREx mission will use spectroscopy — the splitting of light into its component wavelengths — to study the universe. Watch this video to learn more about spectroscopy. NASA’s Goddard Space Flight CenterHere are the three key science investigations SPHEREx will conduct with its colorful all-sky map.
Cosmic OriginsWhat human eyes perceive as colors are distinct wavelengths of light. The only difference between colors is the distance between the crests of the light wave. If a star or galaxy is moving, its light waves get stretched or compressed, changing the colors they appear to emit. (It’s the same with sound waves, which is why the pitch of an ambulance siren seems to go up as its approaches and lowers after it passes.) Astronomers can measure the degree to which light is stretched or compressed and use that to infer the distance to the object.
SPHEREx will apply this principle to map the position of hundreds of millions of galaxies in 3D. By doing so, scientists can study the physics of inflation, the event that caused the universe to expand by a trillion-trillion fold in less than a second after the big bang. This rapid expansion amplified small differences in the distribution of matter. Because these differences remain imprinted on the distribution of galaxies today, measuring how galaxies are distributed can tell scientists more about how inflation worked.
Galactic OriginsSPHEREx will also measure the collective glow created by all galaxies near and far — in other words, the total amount of light emitted by galaxies over cosmic history. Scientists have tried to estimate this total light output by observing individual galaxies and extrapolating to the trillions of galaxies in the universe. But these counts may leave out some faint or hidden light sources, such as galaxies too small or too distant for telescopes to easily detect.
With spectroscopy, SPHEREx can also show astronomers how the total light output has changed over time. For example, it may reveal that the universe’s earliest generations of galaxies produced more light than previously thought, either because they were more plentiful or bigger and brighter than current estimates suggest. Because light takes time to travel through space, we see distant objects as they were in the past. And, as light travels, the universe’s expansion stretches it, changing its wavelength and its color. Scientists can therefore use SPHEREx data to determine how far light has traveled and where in the universe’s history it was released.
Water’s OriginsSPHEREx will measure the abundance of frozen water, carbon dioxide, and other essential ingredients for life as we know it along more than 9 million unique directions across the Milky Way galaxy. This information will help scientists better understand how available these key molecules are to forming planets. Research indicates that most of the water in our galaxy is in the form of ice rather than gas, frozen to the surface of small dust grains. In dense clouds where stars form, these icy dust grains can become part of newly forming planets, with the potential to create oceans like the ones on Earth.
The mission’s colorful view will enable scientists to identify these materials, because chemical elements and molecules leave a unique signature in the colors they absorb and emit.
Big PictureMany space telescopes, including NASA’s Hubble and James Webb, can provide high-resolution, in-depth spectroscopy of individual objects or small sections of space. Other space telescopes, like NASA’s retired Wide-field Infrared Survey Explorer (WISE), were designed to take images of the whole sky. SPHEREx combines these abilities to apply spectroscopy to the entire sky.
By combining observations from telescopes that target specific parts of the sky with SPHEREx’s big-picture view, scientists will get a more complete — and more colorful — perspective of the universe.
More About SPHERExSPHEREx is managed by JPL for NASA’s Astrophysics Division within the Science Mission Directorate in Washington. BAE Systems (formerly Ball Aerospace) built the telescope and the spacecraft bus. The science analysis of the SPHEREx data will be conducted by a team of scientists located at 10 institutions across the U.S. and in South Korea. Data will be processed and archived at IPAC at Caltech, which manages JPL for NASA. The mission principal investigator is based at Caltech with a joint JPL appointment. The SPHEREx dataset will be publicly available.

‘Blood-Soaked’ Eyes: NASA’s Webb, Hubble Examine Galaxy Pair
NASA, ESA, CSA, STScI
Stare deeply at these galaxies. They appear as if blood is pumping through the top of a flesh-free face. The long, ghastly “stare” of their searing eye-like cores shines out into the supreme cosmic darkness.
It’s good fortune that looks can be deceiving.
These galaxies have only grazed one another to date, with the smaller spiral on the left, cataloged as IC 2163, ever so slowly “creeping” behind NGC 2207, the spiral galaxy at right, millions of years ago.
The pair’s macabre colors represent a combination of mid-infrared light from NASA’s James Webb Space Telescope with visible and ultraviolet light from NASA’s Hubble Space Telescope.
Image A: Galaxies IC 2163 and NGC 2207 (Webb and Hubble Image) This observation combines mid-infrared light from NASA’s James Webb Space Telescope, and ultraviolet and visible light from NASA’s Hubble Space Telescope. The galaxies grazed one another millions of years ago. The smaller spiral on the left, cataloged as IC 2163, passed behind NGC 2207, the larger spiral galaxy at right. NASA, ESA, CSA, STScILook for potential evidence of their “light scrape” in the shock fronts, where material from the galaxies may have slammed together. These lines represented in brighter red, including the “eyelids,” may cause the appearance of the galaxies’ bulging, vein-like arms.
The galaxies’ first pass may have also distorted their delicately curved arms, pulling out tidal extensions in several places. The diffuse, tiny spiral arms between IC 2163’s core and its far left arm may be an example of this activity. Even more tendrils look like they’re hanging between the galaxies’ cores. Another extension “drifts” off the top of the larger galaxy, forming a thin, semi-transparent arm that practically runs off screen.
Image B: Galaxies IC 2163 and NGC 2207 (MIRI Image) This mid-infrared image from NASA’s James Webb Space Telescope excels at showing where the cold dust, set off in white, glows throughout these two galaxies, IC 2163 and NGC 2207. The telescope also helps pinpoint where stars and star clusters are buried within the dust. These regions are bright pink. Some of the pink dots may be extremely distant active supermassive black holes known as quasars. NASA, ESA, CSA, STScIBoth galaxies have high star formation rates, like innumerable individual hearts fluttering all across their arms. Each year, the galaxies produce the equivalent of two dozen new stars that are the size of the Sun. Our Milky Way galaxy only forms the equivalent of two or three new Sun-like stars per year. Both galaxies have also hosted seven known supernovae in recent decades, a high number compared to an average of one every 50 years in the Milky Way. Each supernova may have cleared space in their arms, rearranging gas and dust that later cooled, and allowed many new stars to form.
To spot the star-forming “action sequences,” look for the bright blue areas captured by Hubble in ultraviolet light, and pink and white regions detailed mainly by Webb’s mid-infrared data. Larger areas of stars are known as super star clusters. Look for examples of these in the top-most spiral arm that wraps above the larger galaxy and points left. Other bright regions in the galaxies are mini starbursts — locations where many stars form in quick succession. Additionally, the top and bottom “eyelid” of IC 2163, the smaller galaxy on the left, is filled with newer star formation and burns brightly.
Image C: Galaxies IC 2163 and NGC 2207 (Hubble and Webb Images Side by Side) Image Before/AfterWhat’s next for these spirals? Over many millions of years, the galaxies may swing by one another repeatedly. It’s possible that their cores and arms will meld, leaving behind completely reshaped arms, and an even brighter, cyclops-like “eye” at the core. Star formation will also slow down once their stores of gas and dust deplete, and the scene will calm.
Video A: Tour of Galaxies IC 2163 and NGC 2207The James Webb Space Telescope is the world’s premier space science observatory. Webb is solving mysteries in our solar system, looking beyond to distant worlds around other stars, and probing the mysterious structures and origins of our universe and our place in it. Webb is an international program led by NASA with its partners, ESA (European Space Agency) and CSA (Canadian Space Agency).
The Hubble Space Telescope has been operating for over three decades and continues to make ground-breaking discoveries that shape our fundamental understanding of the universe. Hubble is a project of international cooperation between NASA and ESA (European Space Agency). NASA’s Goddard Space Flight Center in Greenbelt, Maryland, manages the telescope and mission operations. Lockheed Martin Space, based in Denver, Colorado, also supports mission operations at Goddard. The Space Telescope Science Institute in Baltimore, Maryland, which is operated by the Association of Universities for Research in Astronomy, conducts Hubble science operations for NASA.

Sols 4348-4349: Smoke on the Water NASA’s Mars rover Curiosity created this composite image from its Mars Hand Lens Imager (MAHLI), located on the turret at the end of the rover’s robotic arm. An onboard process, focus merging, makes a composite of images of the same target — acquired at different focus positions — to bring all (or, as many as possible) features into focus in a single image. Curiosity performed this merge on Oct. 27, 2024, sol 4346 (Martian day 4,346) of the Mars Science Laboratory Mission, at 15:45:47 UTC. NASA/JPL-Caltech/MSSSEarth planning date: Monday, Oct. 28, 2024
Before the science team starts planning, we first look at the latest Navcam image downlinked from Curiosity to see where the rover is located. It can be all too easy to get lost in the scenery of the Navcam and find new places in the distance we want to drive towards, but there’s so much beauty in the smaller things. Today I’ve chosen to show a photo from Curiosity’s hand lens camera, MAHLI, that takes photos so close that we can see the individual grains of the rock.
The planning day usually starts by thinking about these smaller features: What rocks are the closest to the rover? What can we shoot with our laser? What instruments can we use to document these features? Today we planned two sols, and the focus of the close-up contact science became a coating of material that in some image stretches looks like a deep-purple color.
We planned lots of activities to characterize this coating including use of the dust removal tool (DRT) and the APXS instrument on a target called “Reds Meadow.” This target will also be photographed by the MAHLI instrument. The team planned a ChemCam LIBS target on “Midge Lake” as well as a passive ChemCam target on “Primrose Lake” to document this coating with a full suite of instruments. Mastcam will then document the ChemCam LIBS target Midge Lake, and take a mosaic of the vertical faces of a few rocks near to the rover called “Peep Sight Peak” to observe the sedimentary structures here. Mastcam will also take a mosaic of “Pinnacle Ridge,” an area seen previously by the rover, from a different angle. ChemCam is rounding off the first sol with two long-distance RMI mosaics to document the stratigraphy of two structures we are currently driving between: Texoli butte and the Gediz Vallis channel.
In the second sol of the plan, after driving about 20 meters (about 66 feet), Curiosity will be undertaking some environmental monitoring activities before an AEGIS activity that automatically selects a LIBS target in our new workspace prior to our planning on Wednesday morning.

Hello Earth? Space Calling
How it started versus how it’s going for astronaut Nick Hague with ISS Ham Radio on the space station.
Since November 2000, crew members like Hague have used ham radio to communicate with people on Earth through this educational program, also known as Amateur Radio on the International Space Station or ARISS. So far, there have been more than 1,700 events, directly engaging students and listeners from 49 U.S. states, 63 countries, and all seven continents. Students study the space station, radio waves, amateur radio technology, and related topics before their call from space, which encourages interest in STEM.
Now through Nov 17, 2024, ARISS is accepting applications from formal and informal educational institutions and organizations that want to host events in summer or fall of 2025. There is no charge for these calls from space, although host locations may incur some equipment-related costs. Local amateur radio clubs help hosts prepare for their contacts.

Marshall Team Members View Progress Toward Future Artemis FlightsBlake Stewart, lead of the Thrust Vector Control Test Laboratory inside Building 4205 at NASA’s Marshall Space Flight Center, explains how his team tests the mechanisms that steer engine and booster nozzles of NASA’s SLS (Space Launch System) rocket to a group of Marshall team members Oct. 24. The employees were some of the more than 500 team members who viewed progress toward future Artemis flights on bus tours offered by the SLS Program. Building 4205 is also home to the Propulsion Research and Development Laboratory that includes 26 world-class labs and support areas that help the agency’s ambitious goals for space exploration. The Software Integration Lab and the Software Integration Test Facility are among the labs inside supporting SLS that employees visited on the tour. (NASA/Sam Lott)
A group of Marshall team members gather below the development test article for the universal stage adapter that will be used on the second variant of SLS, called Block 1B. The universal stage adapter is located inside one of the high bays in building 4619. The universal stage adapter will connect the Orion spacecraft to the SLS exploration upper stage. With the exploration upper stage, which will be powered by four RL10-C3 engines, SLS will be capable of lifting more than 105 metric tons (231,000 pounds) from Earth’s surface. This extra mass capability enables SLS to send multiple large payloads to the Moon on the same launch. (NASA/Sam Lott)

Center Commemorates National Disability Employment Awareness MonthBy Serena Whitfield
In conjunction with National Disability Employment Awareness Month, NASA’s Marshall Space Flight Center held anagencywide virtual event hosted by the Office of Diversity and Equal Opportunity on Oct. 24.
Marshall team members watched the Webex event in Building 4221.
From left, Tora Henry, director of the Office of Diversity and Equal Opportunity at Marshall, Chip Dobbs, supply management specialist at Marshall, and Marshall Associate Director Roger Baird pause for a photo following the Oct. 24 virtual event the center hosted as part of National Disability Awareness Month. NASA/Serena WhitfieldIn alignment with the month’s national theme, “Access to Good Jobs for All,” the program highlighted the perspectives of people with disabilities in the workplace as they navigate the work lifecycle – from applying, to onboarding, career growth and advancement, and day-to-day engagements.
The event began with Marshall Associate Director Roger Baird welcoming NASA team members.
“NASA is dedicated to inclusive hiring practices and providing pathways for good jobs and career success for all employees, including workers with disabilities,” Baird said. “Some ways we do this is through targeted recruitment of qualified individuals with disabilities through accessible vacancy announcements, outreach to students with disabilities, and community partnerships.”
NASA also utilizes Schedule A Authority, a non-competitive Direct Hiring Authority to hire people with disabilities without competition.
Baird introduced event moderator Joyce Meier, logistics manager at Marshall, who welcomed panelists Casey Denham, Kathy Clark, Paul Spann, and Paul Sullivan, all NASA team members. The panelists from the disability community discussed their work lifecycles, lessons learned in the workplace, and shared a demonstration on colorblindness and its impact.
Denham discussed some of the best practices for onboarding employees with neurodiversity, a term used to describe people whose brains develop or work differently than the typical brain.
Marshall team members watch the agencywide virtual event commemorating National Disability Employment Awareness Month. NASA/Serena WhitfieldClark talked about what can be done to continue raising awareness and advocating for disability rights. She said NASA empowers its workforce with knowledge so they can be informed allies to team members with disabilities and foster a safe and inclusive working environment.
Spann gave insight into practical steps employers can take to accommodate candidates with deafness, and Sullivan spoke about some key considerations NASA managers should keep in mind to make the job application process more accessible to candidates with low vision.
Guest speaker Chip Dobbs, supply management specialist at Marshall, talked about his personal experiences with being deaf. Dobbs has worked at NASA for 29 years and said he has never let his disability hold him back, but instead uses it as a gateway to inspire and connect with others.
The event ended with closing remarks from Tora Henry, director of the Office of Diversity and Equal Opportunity at Marshall. The virtual event placed importance on planning for NASA’s future by promoting equality and addressing the barriers people with disabilities face in the workplace.
“As we celebrate National Disability Employment Awareness Month, keep in mind that NASA’s mission of exploring the unknown and pushing the boundaries of human potential requires the contributions of every mind, skill set, and perspective,” Baird said. “Our commitment to inclusivity ensures that no talent goes untapped, and no idea goes unheard because together, we’re not just reaching for the stars, we’re showing the world what’s possible when everyone has a seat at the table.”
A recording of the event is available here. Learn more about NASA’s agencywide resources for individuals with disabilities as well as the agency’s Disability Employment Program.

Take 5 with Brooke RhodesBy Wayne Smith
When human exploration of Mars becomes a reality and more than just the stuff of science fiction, Brooke Rhodes will be eager to investigate what astronauts discover on the Red Planet.
From listening to her talk about her work as an engineer at NASA’s Marshall Space Flight Center, it’s easy to grasp her excitement about the future of human space exploration and NASA’s Moon to Mars architecture.
Brooke Rhodes is currently on detail as the branch chief of the Avionics and Software Ground Systems Test Branch at NASA’s Marshall Space Flight Center. Working in the Instrument Development, Integration and Test Branch for the past seven years, she’s been responsible for the integration and testing of International Space Station payloads. NASA“I can’t wait for the Mars rovers to have some human company,” said Rhodes, who recently began a detail as the chief of Marshall’s Avionics and Software Ground Systems Test Branch. “I need to know if we can grow Mark Watney (of The Martian movie fame) quantities of potatoes up there. Everything we do to prepare to return humans to the Moon and establish a presence in deep space is building toward putting boots on Mars. It’s an honor and a privilege to be even a small part of it.”
Rhodes also appreciates the responsibility she takes on in any form in NASA’s exploration missions to benefit humanity. After all, she has worked on hardware for the International Space Station and has had supporting roles for the Mars Ascent Vehicle and Artemis missions.
“We at Marshall hold an incredible amount of responsibility: responsibility for the welfare of the crew on the space station, responsibility for the welfare of the crew on the Artemis missions, and even the welfare of humanity through the responsibility we have for science on the station and elsewhere,” said Rhodes, who is from Petal, Mississippi, and has worked at Marshall for seven years. “When your missions are as critical as ours, it’s nearly impossible to not be motivated.”
Now, on to Mars.
Question: What is your position and what are your primary responsibilities?
Rhodes: I recently began the detail as the branch chief of the Avionics and Software Ground Systems Test Branch, ES53. Our branch is primarily responsible for the development of hardware-in-the-loop and software development facilities for the Artemis and MAV (Mars Ascent Vehicle) missions. My home organization is ES61, the Instrument Development, Integration and Test Branch, where I’ve been responsible for the integration and testing of International Space Station payloads for the past several years.

Rhodes: One really cool moment that sticks out was the first time I saw hardware I had been responsible for being used in space. I spent several years as the integration and test lead of the Materials Science Research Rack (MSRR) Sample Cartridge Assemblies (SCAs) and we shipped our first batch of SCAs to the space station in 2018. That shipment was the culmination of years of intense effort and teamwork, so to see them onboard and about to enable materials science was an incredible feeling. There was a moment in particular that felt a bit surreal: prior to our SCA shipment the crew discovered they were missing a couple of fasteners from the onboard furnace, so we had those shipped to us from Europe and I packed them into the SCA flight foam before they shipped to the launch site. The next time I saw those fasteners they were being held up to a camera by one of the crew members, asking if those were the ones they needed for the furnace. Putting fasteners into foam didn’t take much effort, but what it represented was much bigger: being a small part of an international effort to enable science off the Earth, for the Earth, was an incredible moment I’ll carry with me for the rest of my career.
Question: Who or what inspired you to pursue an education/career that led you to NASA and Marshall?
Rhodes: I had a couple of lightbulb moments my junior year of high school that eventually set me on my current career path. I very specifically recall sitting in my physics I class and learning how to calculate the planetary motion of Jupiter and thinking I had never learned about anything cooler. Even then, though, NASA didn’t really enter my thoughts. Growing up, working for NASA didn’t even occur to me as something people could actually do – being a “rocket scientist” was just an abstract concept people threw around to indicate something was difficult.
That changed later when the same teacher who had been teaching us planetary motion took us on a field trip to Kennedy Space Center. The tour guide showing us around the Vehicle Assembly Building was a young employee who said he had majored in aerospace engineering at the University of Tennessee. That was the second lightbulb moment: here was a young person from the Southeast, just like me, who had done something tangible in order to work for NASA. That seemed easy enough, so I decided to major in aerospace engineering at Mississippi State and one day work for NASA. That turned out to not be easy, but definitely doable.
While at Mississippi State, I was able to complete three NASA internships, one at the Jet Propulsion Laboratory and two at Marshall. Eventually, I was hired on full-time at NASA’s Johnson Space Center, but wound up making my way back to Marshall, where I’ve been ever since. There’s no place on the planet better for enthusiasts of both aerospace engineering and football.

I didn’t actually mean that literally, but then I married Matthew Rhodes and did, indeed, become Mrs. Rhodes.
Question: What advice do you have for employees early in their NASA career or those in new leadership roles?
Rhodes: Scary is good. If you aren’t stepping out of your comfort zone you probably aren’t growing, and if you’re experiencing imposter syndrome, you’re probably the right person for the job.
Question: What do you enjoy doing with your time while away from work?
Rhodes: While away from work I tend to invest too much of my mental wellbeing into football. To recover from the stresses of work and my football teams being terrible, I like to explore National Parks. The U.S. has some of the most diverse scenery anywhere in the world, and I love getting outside and exploring it.

Planets Beware: NASA Unburies Danger Zones of Star ClusterMost stars form in collections, called clusters or associations, that include very massive stars. These giant stars send out large amounts of high-energy radiation, which can disrupt relatively fragile disks of dust and gas that are in the process of coalescing to form new planets.
A team of astronomers used NASA’s Chandra X-ray Observatory, in combination with ultraviolet, optical, and infrared data, to show where some of the most treacherous places in a star cluster may be, where planets’ chances to form are diminished.
In this new composite image, Chandra data (purple) shows the diffuse X-ray emission and young stars in Cygnus OB2, and infrared data from NASA’s now-retired Spitzer Space Telescope (red, green, blue, and cyan) reveals young stars and the cooler dust and gas throughout the region.X-ray: NASA/CXC/SAO/J. Drake et al, IR: NASA/JPL-Caltech/Spitzer; Image Processing: NASA/CXC/SAO/N. WolkThe target of the observations was Cygnus OB2, which is the nearest large cluster of stars to our Sun – at a distance of about 4,600 light-years. The cluster contains hundreds of massive stars as well as thousands of lower-mass stars. The team used long Chandra observations pointing at different regions of Cygnus OB2, and the resulting set of images were then stitched together into one large image.
The deep Chandra observations mapped out the diffuse X-ray glow in between the stars, and they also provided an inventory of the young stars in the cluster. This inventory was combined with others using optical and infrared data to create the best census of young stars in the cluster.
In a new composite image, the Chandra data (purple) shows the diffuse X-ray emission and young stars in Cygnus OB2, and infrared data from NASA’s now-retired Spitzer Space Telescope (red, green, blue, and cyan) reveals young stars and the cooler dust and gas throughout the region.
In these crowded stellar environments, copious amounts of high-energy radiation produced by stars and planets are present. Together, X-rays and intense ultraviolet light can have a devastating impact on planetary disks and systems in the process of forming.
Planet-forming disks around stars naturally fade away over time. Some of the disk falls onto the star and some is heated up by X-ray and ultraviolet radiation from the star and evaporates in a wind. The latter process, known as “photoevaporation,” usually takes between five and 10 million years with average-sized stars before the disk disappears. If massive stars, which produce the most X-ray and ultraviolet radiation, are nearby, this process can be accelerated.
The researchers using this data found clear evidence that planet-forming disks around stars indeed disappear much faster when they are close to massive stars producing a lot of high-energy radiation. The disks also disappear more quickly in regions where the stars are more closely packed together.
For regions of Cygnus OB2 with less high-energy radiation and lower numbers of stars, the fraction of young stars with disks is about 40%. For regions with more high-energy radiation and higher numbers of stars, the fraction is about 18%. The strongest effect – meaning the worst place to be for a would-be planetary system – is within about 1.6 light-years of the most massive stars in the cluster.
A separate study by the same team examined the properties of the diffuse X-ray emission in the cluster. They found that the higher-energy diffuse emission comes from areas where winds of gas blowing away from massive stars have collided with each other. This causes the gas to become hotter and produce X-rays. The less energetic emission probably comes from gas in the cluster colliding with gas surrounding the cluster.
Two separate papers describing the Chandra data of Cygnus OB2 are available. The paper about the planetary danger zones, led by Mario Giuseppe Guarcello (National Institute for Astrophysics in Palermo, Italy), appeared in the November 2023 issue of the Astrophysical Journal Supplement Series, and is available here. The paper about the diffuse emission, led by Juan Facundo Albacete-Colombo (University of Rio Negro in Argentina) was published in the same issue of Astrophysical Journal Supplement, and is available here.

NASA Begins New Deployable Solar Array Tech Demo on Pathfinder SpacecraftNASA recently evaluated initial flight data and imagery from Pathfinder Technology Demonstrator-4 (PTD-4), confirming proper checkout of the spacecraft’s systems including its on-board electronics as well as the payload’s support systems such as the small onboard camera. Shown is a test image of Earth taken by the payload camera, shortly after PTD-4 reached orbit. This camera will continue photographing the technology demonstration during the mission.

The camera will capture images of the Lightweight Integrated Solar Array and anTenna upon deployment.NASAPayload operations are now underway for the primary objective of the PTD-4 mission – the demonstration of a new power and communications technology for future spacecraft. The payload, a deployable solar array with an integrated antenna called the Lightweight Integrated Solar Array and anTenna, or LISA-T, has initiated deployment of its central boom structure. The boom supports four solar power and communication arrays, also called petals. Releasing the central boom pushes the still-stowed petals nearly three feet away from the spacecraft bus. The mission team currently is working through an initial challenge to get LISA-T’s central boom to fully extend before unfolding the petals and beginning its power generation and communication operations.
Small spacecraft on deep space missions require more electrical power than what is currently offered by existing technology. The four-petal solar array of LISA-T is a thin-film solar array that offers lower mass, lower stowed volume, and three times more power per mass and volume allocation than current solar arrays. The in-orbit technology demonstration includes deployment, operation, and environmental survivability of the thin-film solar array.
“The LISA-T experiment is an opportunity for NASA and the small spacecraft community to advance the packaging, deployment, and operation of thin-film, fully flexible solar and antenna arrays in space. The thin-film arrays will vastly improve power generation and communication capabilities throughout many different mission applications,” said John Carr, deputy center chief technologist at NASA’s Marshall Space Flight Center. “These capabilities are critical for achieving higher value science alongside the exploration of deep space with small spacecraft.”
NASA teams are testing a key technology demonstration known as LISA-T, short for the Lightweight Integrated Solar Array and anTenna. It’s a super compact, stowable, thin-film solar array that when fully deployed in space, offers both a power generation and communication capability for small spacecraft. LISA-T’s orbital flight test is part of the Pathfinder Technology Demonstrator series of missions. (NASA)The Pathfinder Technology Demonstration series of missions leverages a commercial platform which serves to test innovative technologies to increase the capability of small spacecraft. Deploying LISA-T’s thin solar array in the harsh environment of space presents inherent challenges such as deploying large highly flexible non-metallic structures with high area to mass ratios. Performing experiments such as LISA-T on a smaller, lower-cost spacecraft allows NASA the opportunity to take manageable risk with high probability of great return. The LISA-T experiment aims to enable future deep space missions with the ability to acquire and communicate data through improved power generation and communication capabilities on the same integrated array.
The PTD-4 small spacecraft is hosting the in-orbit technology demonstration called LISA-T. The PTD-4 spacecraft deployed into low Earth orbit from SpaceX’s Transporter-11 rocket, which launched from Space Launch Complex 4E at Vandenberg Space Force Base in California on Aug. 16. Marshall designed and built the LISA-T technology as well as LISA-T’s supporting avionics system. NASA’s Small Spacecraft Technology program, based at NASA’s Ames Research Center and led by the agency’s Space Technology Mission Directorate, funds and manages the PTD-4 mission as well as the overall Pathfinder Technology Demonstration mission series. Terran Orbital Corporation of Irvine, California, developed and built the PTD-4 spacecraft bus, named Triumph.
NASA SPoRT’s Streamflow-AI Helps with Flood Preparedness in TexasBy Paola Pinto
For more than two decades, the NASA Short-term Prediction Research and Transition Center (SPoRT) within the NASA Earth Science Office at Marshall Space Flight Center has been at the forefront of developing and maintaining decision-making tools for meteorological predictions.
This image represents the first instance of predictions getting into moderate flooding in Pine Island Bayou. At 14 feet (start of the moderate flooding category), Cooks Lake Road becomes unsafe for most vehicles. NASAJonathan Brazzell, a service hydrologist at the National Weather Service (NWS) office in Lake Charles, Louisiana, highlighted a recent example of SPoRT’s impact while he was doing forecasting for Texas streams.
Brazzell, who manages the South Texas and South Louisiana regions, emphasized the practical applications and significant impacts of the Machine Learning model developed by NASA SPoRT to predict future stream heights, known as the SPoRT Streamflow A.I. During a heavy rainfall event this past spring, he noted the challenge of forecasting flooding beyond 48 hours. SPoRT has worked closely with the NWS offices to develop a machine learning tool capable of predicting river flooding beyond two days and powered by the SPoRT Land Information System.
“Previously, we relied on actual gauge information and risk assessments based on predicted precipitation,” Brazzell said. “Now, with this machine learning, we have a modeling tool that provides a much-needed predictive capability.”
During forecasted periods of heavy precipitation from early to mid-May, Brazzell monitored potential flooding events and their magnitude using NASA SPoRT’s Streamflow-AI, which provided essential support to the Pine Island Bayou and Big Cow Creek communities in south Texas.
Streamflow A.I. enabled local authorities to provide advance notice, allowing residents to prepare adequately for the event. Due to the benefit of three to seven-day flood stage predictions, the accurate forecasts helped county officials decide on road closures and evacuation advisories; community officials advised residents to gather a seven-day supply of necessities and relocate their vehicles, minimizing disruption and potential damage.
Brazzell highlighted specific instances where the machine learning outputs were critical. For example, during the event that peaked around May 6, Streamflow A.I. accurately predicted the rise in stream height, allowing for timely road closures and advisories. These predictions were shared with county officials and were pivotal in their decision-making process.
This image shows the water levels after rainfall and predicts a moderate stream height in Pine Island Bayou. NASABrazzell shared that integrating SPoRT’s machine learning capabilities with their existing tools, such as flood risk mapping, proved invaluable. Although the machine learning outputs had been operational for almost two years after Hurricane Harvey, this season has provided their first significant applications in real-time scenarios due to persistent conditions of below-normal precipitation and ongoing drought.
He also mentioned the broader applications of Streamflow A.I., including its potential use in other sites beyond those currently being monitored. He expressed interest in expanding the use of machine learning stream height outputs to additional locations, citing the successful application in current sites as a compelling reason for broader implementation.
NASA SPoRT users’ experiences emphasize how crucial advanced prediction technologies are in hydrometeorology and emergency management operations. Based on Brazzell’s example, it is reasonable to say that the product’s ability to provide accurate, timely data greatly improves decision-making processes and ensures public safety. The partnership between NASA SPoRT and operational agencies like NOAA/NWS and county response teams demonstrates how research and operations can be seamlessly integrated into everyday practices, making a tangible difference in communities vulnerable to high-impact events.
As the Streamflow A.I. product continues to evolve and expand its applications, it holds significant promise for improving disaster preparedness and response efforts across various regions that experience different types of flooding events.
The Streamflow-AI product provides a 7-day river height or stage forecasts at select gauges across the south/eastern U.S. You can find the SPoRT training item on Streamflow-AI here.
