NASA Announces Teams for 2024 Student Launch Challenge

NASA has announced the 70 teams representing 24 states and Puerto Rico selected to compete in the 2024 Student Launch Challenge.

The annual competition – one of NASA’s nine Artemis Student Challenges – requires middle/high school and college/university students to design, build, and fly a high-powered amateur rocket and scientific payload.

Students from the AIAA Orange Country Section team of Irvine, California, display their rocket to news media and the public during Rocket Fair – an annual showcase event of NASA’s Student Launch competition April 2023.

The nine-month-long challenge will culminate with on-site events April 10-14, 2024, with final launches April 13 at Bragg Farms in Toney, Alabama, just minutes north of NASA’s Marshall Space Flight Center. Teams are not required to travel for their final launch, having the option to launch from a qualified. Details are outlined in the Student Launch Handbook.

Each year NASA implements a new payload challenge to reflect relevant missions. This year’s payload challenge is inspired by the Artemis missions, which seek to land the first woman and first person of color on the Moon.

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 four STEMnauts, non-living objects representing astronauts. Students will choose metrics to determine the endurance of the lander, considering acceptable descent and landing parameters.

University/college teams are required to meet the 2024 payload requirements set by NASA, but middle/high school teams have the option to tackle the same challenge or design their own payload experiment.

Student teams and attendees of NASA’s 2023 Student Launch competition observe a rocket take flight near NASA’s Marshall Space Flight Center in Huntsville, Alabama, April 2023.

Student teams will undergo detailed reviews by NASA personnel to ensure the safety and feasibility of their rocket and payload designs. All teams must declare their rocket’s targeted altitude for final launch day during a preliminary design review. The team closest to their target will win the Altitude Award, just one of multiple awards presented to deserving teams at the end of the competition. Other awards include overall winner, vehicle design, experiment design, social media presence, and more.

In addition to the engineering and science side of the competition, students must also participate in outreach efforts such as engaging with local schools and maintaining effective social media accounts. Student Launch is an all-encompassing challenge and aims to prepare the next generation for the professional world of space exploration.

The competition is managed by Marshall’s Office of STEM Engagement (OSTEM). Additional funding and support are provided by NASA’s OSTEM via the Next Gen STEM project, NASA’s 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.

Racers Run, Bike, Run to Beat the Space Station in Annual Duathlon

On the morning of Sept. 30, 160 athletes ran and biked across NASA’s Marshall Space Flight Center and Redstone Arsenal in a race to beat the International Space Station. The annual “Racin’ the Station” duathlon is a run-bike-run event where participants try to complete the course faster than it takes the space station to complete one Earth orbit, which is every 91 minutes, 12 seconds.

Organizers track the starting location of the space station at the race start, and a costumed pacer keeps up with the station time on the course as a visual marker for participants to stay ahead of. Before the race, organizers drew a to-scale Space Launch System Block 1 rocket in chalk onto the Activities Building parking lot near the race transition area. The race began in 2012, and this year was the 11th running (the event did not occur in 2020 due to the pandemic).

Racers competed to beat the International Space Station in the annual “Racin’ the Station” duathlon Sept. 30 at Marshall Space Flight Center. The goal of the race is to complete the course faster than the station takes to complete one Earth orbit, or just over 90 minutes.

“Racin’ the Station” is not just an athletic event,” said race director and Marshall engineer Kent Criswell. “I try to also focus on educating the community about what Marshall is doing. For example, the water aid station on the run course – I call it the ECLSS (Environmental Control and Life Support System) station, but I also assure them that the water is not recycled urine from astronauts! It is a great event for any geek in the southeast — people drive all the way from Birmingham and Nashville to compete.”

The event began at 7:50 a.m. with an opening ceremony in Marshall’s Activities Building, where racers got pumped up watching the Metallica/NASA “Fuel” video for Artemis II. With the weather slowly warming, the field took off at 8:15 a.m., with a model rocket launch as the starting signal. The “station pacer” this year was dressed as Star-Lord, a superhero character appearing in the comic book and film series “Guardians of the Galaxy.”

The course is three legs: a 3.14 km run, followed by a 23 km bicycle ride, and another 3.14 km run, with the start and finish line at Marshall’s Wellness Center. Race organizers arranged the distances to coincide with the number pi, approximately 3.14.

Participants can complete the entire race as an individual, or as a relay team. Eighteen teams and 124 individual racers competed, and 92 of those beat the station this year.

Runners compete in one of the two 3.14 km runs in “Racin’ the Station.”

Experience Solar Eclipse on Oct. 14

On Oct. 14, 2023, and April 8, 2024, the entire United States and millions around the world will be able to view a solar eclipse.

A map shows the 48 contiguous U.S. states with two dark bands running across it. One band, labeled "2023 Annular Solar Eclipse," crosses states from Oregon to Texas. The other band, labeled "2024 Total Solar Eclipse," crosses states from Texas to Maine.

There are three different kinds of solar eclipses: total, annular, and partial. When the Moon is far from the Earth, its size is too small to completely cover the Sun, thus an annular eclipse is observed, like what is expected on Oct. 14. When the Moon is close to the Earth, its larger size completely covers the Sun, causing a total eclipse, which will occur on April 8, 2024. A partial eclipse occurs when the Earth, Moon, and Sun are not perfectly aligned so only a part of the Sun will appear to be covered, giving it a crescent shape. During a total or annular solar eclipse, people outside the totality/annularity paths will see a partial solar eclipse.

Mitzi Adams, NASA Marshall Space Flight Center​ Heliophysics and Planetary Science branch assistant chief, shares her observations during the five total eclipses she has experienced. “It is like nothing you’ve ever experienced before. It’s sort of like somebody puts a bowl on top of Earth right above where you’re standing. In the middle of the day, it gets darker, but you can still see light around the rim.” Adams explains. “You can essentially observe a sunrise or sunset. The temperatures cool. The wind picks up. The birds may go to roost, or the coyotes may howl.”

During an annular eclipse like the one coming up on Oct. 14, even with the sun covered up to 90%, the sky remains fairly bright. Those in the path of annularity will have a chance to observe the famed “ring of fire” effect, but it is important to manage your expectations and to remember that solar viewing glasses will be needed during the event’s entirety.

Bill Cooke, NASA’s Meteoroid Environment Office lead and eclipse enthusiast, says he is most looking forward to the 2024 total eclipse because totality, when the sun is covered 100%, will last much longer than the last total eclipse in 2017 – up to nearly four and a half minutes.

In any of the upcoming eclipse events, in our technology-fueled world, you may also experience some electronic changes as the moon moves across Earth and the ionosphere cools.

The ionosphere forms the boundary between the Earth’s lower atmosphere – where we live and breathe – and the vacuum of space. It is formed when particles are charged, or ionized, by solar radiation. A total solar eclipse effectively “turns off” the ionosphere’s primary charging mechanism, mimicking nighttime conditions, so the many communications signals passing through the ionosphere could be disrupted.

GPS signals could produce location errors. Radio waves could change, sometimes even allowing Ham Radio operators to send or receive transmissions over longer distances.

The ionosphere is also home to many NASA satellites, including the International Space Station.

Experiencing an eclipse is one way that everyone can participate in NASA Science. Depending on your access to different types of technology (phones, laptops, telescopes), there are several NASA Citizen Science projects you can participate in that relate to the Sun’s corona and the effects of the Moon’s shadow on Earth’s upper atmosphere.

  • GLOBE Observer
    • Help monitor the conditions of clouds, water (especially as a habitat for mosquitoes), plants (trees and other land cover), and see change over time.
  • Solar Jet Hunter
    • Join the hunt for solar jets – enigmatic bursts of energy from our own star – the Sun.
  • Planet Hunters Transiting Exoplanet Survey Satellite (TESS)
    • Find planets that will help us understand how these extrasolar systems form and evolve over time
  • Eclipse Soundscapes
    • Provide multi-sensory observations and recorded sound data to study how solar eclipses affect life on Earth!    
  • HamSCI
    • Advance scientific research and understanding through amateur radio activities.
  • Radio JOVE
    • Observe and analyze natural radio emissions of Jupiter, the Sun, and our galaxy using their own easy to construct radio telescopes.
  • Sungrazer Project
    • Become a “Comet Hunter”, and immediately begin looking for new comets in the spacecraft data. 

Regardless of how you plan to experience a solar eclipse, or any solar viewing for that matter, remember to always do so safely.

NASA’s Bennu Asteroid Sample Contains Carbon, Water

Initial studies of the 4.5-billion-year-old asteroid Bennu sample collected in space and brought to Earth by NASA show evidence of high-carbon content and water, which together could indicate the building blocks of life on Earth may be found in the rock. NASA made the news Oct. 11 from its Johnson Space Center where leadership and scientists showed off the asteroid material for the first time since it landed in September.

This finding was part of a preliminary assessment of NASA’s OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification and Security – Regolith Explorer) science team.

“The OSIRIS-REx sample is the biggest carbon-rich asteroid sample ever delivered to Earth and will help scientists investigate the origins of life on our own planet for generations to come,” said NASA Administrator Bill Nelson. “Almost everything we do at NASA seeks to answer questions about who we are and where we come from. NASA missions like OSIRIS-REx will improve our understanding of asteroids that could threaten Earth while giving us a glimpse into what lies beyond. The sample has made it back to Earth, but there is still so much science to come – science like we’ve never seen before.”  

Although more work is needed to understand the nature of the carbon compounds found, the initial discovery bodes well for future analyses of the asteroid sample. The secrets held within the rocks and dust from the asteroid will be studied for decades to come, offering insights into how our solar system was formed, how the precursor materials to life may have been seeded on Earth, and what precautions need to be taken to avoid asteroid collisions with our home planet.

The goal of the OSIRIS-REx sample collection was 60 grams of asteroid material. Curation experts at NASA Johnson, working in new clean rooms built especially for the mission, have spent 10 days so far carefully disassembling the sample return hardware to obtain a glimpse at the bulk sample within. When the science canister lid was first opened, scientists discovered bonus asteroid material covering the outside of the collector head, canister lid, and base. There was so much extra material it slowed down the careful process of collecting and containing the primary sample.

“Our labs were ready for whatever Bennu had in store for us,” said Vanessa Wyche, director, NASA Johnson. “We’ve had scientists and engineers working side-by-side for years to develop specialized gloveboxes and tools to keep the asteroid material pristine and to curate the samples so researchers now and decades from now can study this precious gift from the cosmos.”

Within the first two weeks, scientists performed “quick-look” analyses of that initial material, collecting images from a scanning electron microscope, infrared measurements, X-ray diffraction, and chemical element analysis. X-ray computed tomography was also used to produce a 3D computer model of one of the particles, highlighting its diverse interior. This early glimpse provided the evidence of abundant carbon and water in the sample.

“As we peer into the ancient secrets preserved within the dust and rocks of asteroid Bennu, we are unlocking a time capsule that offers us profound insights into the origins of our solar system,” said Dante Lauretta, OSIRIS-REx principal investigator, University of Arizona, Tucson. “The bounty of carbon-rich material and the abundant presence of water-bearing clay minerals are just the tip of the cosmic iceberg. These discoveries, made possible through years of dedicated collaboration and cutting-edge science, propel us on a journey to understand not only our celestial neighborhood but also the potential for life’s beginnings. With each revelation from Bennu, we draw closer to unraveling the mysteries of our cosmic heritage.”

For the next two years, the mission’s science team will continue characterizing the samples and conduct the analysis needed to meet the mission’s science goals. NASA will preserve at least 70% of the sample at Johnson for further research by scientists worldwide, including future generations of scientists. As part of OSIRIS-REx’s science program, a cohort of more than 200 scientists around the world will explore the regolith’s properties, including researchers from many U.S. institutions, NASA partners JAXA (Japan Aerospace Exploration Agency), CSA (Canadian Space Agency), and other scientists from around the world. Additional samples will also be loaned later this fall to the Smithsonian Institution, Space Center Houston, and the University of Arizona for public display.

NASA’s Goddard Space Flight Center provides overall mission management, systems engineering, and the safety and mission assurance for OSIRIS-REx. Lauretta, the principal investigator, leads the science team and the mission’s science observation planning and data processing. Lockheed Martin Space in Littleton, Colorado, built the spacecraft, provided flight operations, and was responsible for capsule recovery. Goddard and KinetX Aerospace were responsible for navigating the OSIRIS-REx spacecraft. Curation for OSIRIS-REx, including processing the sample when it arrived on Earth, is taking place at NASA Johnson.

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

Webb Captures an Ethereal View of NGC 346

One of the greatest strengths of NASA’s James Webb Space Telescope is its ability to give astronomers detailed views of areas where new stars are being born. The latest example, showcased in a new image from Webb’s MIRI (Mid-Infrared Instrument), is NGC 346 – the brightest and largest star-forming region in the SMC (Small Magellanic Cloud).

The SMC is a satellite galaxy of the Milky Way, visible to the unaided eye in the southern constellation Tucana. This small companion galaxy is more primeval than the Milky Way in that it possesses fewer heavy elements, which are forged in stars through nuclear fusion and supernova explosions, compared to our own galaxy.

The lower half of this image contains arcs of bluish material that form a boat-like shape. One end of these arcs points to the top right of the image, while the other end points toward the bottom left. Another plume of blue filaments expands from the center to the top left, resembling the mast of a sailboat. Within and extending beyond the boat shape are translucent curtains of pink, which appear atop the boat shape as well and cover most of the image. Stars are noticeably scarce. A couple dozen bright pink patches with six short diffraction spikes are scattered within the blue filaments. Many faint blue dots, or stars, also speckle the background, which is black or dark gray.
This new infrared image of NGC 346 from NASA’s James Webb Space Telescope’s Mid-Infrared Instrument (MIRI) traces emission from cool gas and dust. In this image blue represents silicates and sooty chemical molecules known as polycyclic aromatic hydrocarbons, or PAHs.
NASA, ESA, CSA, STScI, N. Habel (JPL). Image Processing: P. Kavanagh (Maynooth University).

Since cosmic dust is formed from heavy elements like silicon and oxygen, scientists expected the SMC to lack significant amounts of dust. However the new MIRI image, as well as a previous image of NGC 346 from Webb’s Near-Infrared Camera released in January, show ample dust within this region.

In this representative-color image, blue tendrils trace emission from material that includes dusty silicates and sooty chemical molecules known as polycyclic aromatic hydrocarbons, or PAHs. More diffuse red emission shines from warm dust heated by the brightest and most massive stars in the heart of the region. An arc at the center left may be a reflection of light from the star near the arc’s center. (Similar, fainter arcs appear associated with stars at lower left and upper right.) Lastly, bright patches and filaments mark areas with abundant numbers of protostars. The research team looked for the reddest stars, and found 1,001 pinpoint sources of light, most of them young stars still embedded in their dusty cocoons.

By combining Webb data in both the near-infrared and mid-infrared, astronomers are able to take a fuller census of the stars and protostars within this dynamic region. The results have implications for our understanding of galaxies that existed billions of years ago, during an era in the universe known as “cosmic noon,” when star formation was at its peak and heavy element concentrations were lower, as seen in the SMC.

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 the Canadian Space Agency. Several NASA centers contributed to the project, including NASA’s Marshall Space Flight Center.

      Center Commemorates National Disability Employment Awareness Month
      By 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 Whitfield In 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 Whitfield Clark 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 Rhodes
      By 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.
      NASA astronaut Ricky Arnold, a space station crew member for Expedition 56, holds up a fastener for the Materials Science Laboratory, which Rhodes packed for shipment to the orbiting laboratory in 2018. “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.” Photo courtesy of Brooke Rhodes Interestingly, my physics I teacher’s name was Mrs. Rhodes, and I used to joke with my classmates that I wanted to be Mrs. Rhodes when I grew up. 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 Cluster
      Most 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. Wolk The 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 Spacecraft
      NASA 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. 
      A test image of Earth taken by NASA’s Pathfinder Technology Demonstrator-4’s onboard camera. The camera will capture images of the Lightweight Integrated Solar Array and anTenna upon deployment.NASA Payload 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 Texas
      By 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. NASA Jonathan 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. NASA Brazzell 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.
      Pinto is a research associate at the University of Alabama in Huntsville, specializing in communications and user engagement for NASA SPoRT.

      Dr. Nipa Phojanamongkolkij does not always do things the traditional way. As a systems engineer (SE) at Langley Research Center working closely with the Aeronautics Research Mission Directorate, Nipa pushes boundaries and draws connections where few others would think to look. When she envisioned a way to use ChatGPT to help SE teams working on the Advanced Air Mobility Mission, she presented her initial idea to her team wondering, “Is this crazy?” Her idea evolved into a successful prototype, which is now used for air traffic management in the Airspace Operations and Safety Program. She has also leveraged natural language programming and NASA’s database of lessons learned to create a bot for flagging potential risks and mitigations in real time. Nipa’s journey in becoming the digital transformer she is today involves her ability to combine engineering principles and business outcomes with creative, human-centered approaches. 
      Nipa received an MS and PhD in industrial and systems engineering from Arizona State University after moving to the United States from Bangkok, Thailand, where she received her BS degree in electronics engineering. She joined NASA 15 years ago after honing her data analysis and process improvement skills in the business sector at Pepsi Corporation. Her previous experience molded her focus on demonstrating benefit and return on investment. In addition to a business-oriented mindset, Nipa credits much of her success at NASA to her abilities as an active listener, which helps her understand customer needs and address paint points.  
      One cross-cutting challenge Nipa noticed within the agency’s approach to SE was the issue of silos, particularly in handling requirements and research data. Many engineers stored information in documents on individual computers or SharePoint folders, making it difficult to share data and draw connections across missions, directorates, and centers. As a systems engineer, Nipa and her team work to pull these disparate elements into a connected digital format using methodology called model-based systems engineering (MBSE). “You can think of it like a gigantic database where you have everything connected—a table of research papers, a table of requirements, and a table of concept of operations documents,” she says.  
      However, using and leveraging this system requires specialized knowledge of the MBSE discipline and modeling language. To centralize system concept, architecture, and requirement data while democratizing access to it, Nipa conceived a way to leverage ChatGPT as an intermediary between the user and database. In fiscal year 2023, she received funding for her idea as a Digital Transformation Prototype Test, “Requirement Discovery Using Embedded Knowledge Graph with ChatGPT.” Nipa and her team developed a web-based dashboard that translates user questions into database queries and turns the database responses back into readable answers for the user. Nipa and her team curated the research used to create the database, reducing the chances of AI hallucination and misinformation. Using ChatGPT as a translator, general users benefitted from the system without needing to know how to formulate graph database queries.  
      Requirement creation through this system was seven times faster than traditional processes and yielded results comparable to those created by subject matter experts. In some cases, the approach even resulted in more creative requirements than human-generated ones. Nipa’s prototype allowed SEs to more efficiently analyze connections between existing requirements, predict new connections, and generate new requirements, streamlining critical processes for her team. The approach could benefit SEs across NASA centers, directorates, and missions and holds exciting potential for other use cases, such as generating candidate requirements and analyzing project risk. According to NASA Digital Engineering Lead Terry Hill, “The future of engineering is understanding how to do it from a data-centric perspective. Enabling the use of new and evolving technologies like artificial intelligence, machine learning, and large language models will aid our engineers to accomplish greater things and augment our workforce.” 
      Nipa and her team were recognized for their innovative work, receiving a Systems Engineering Technical Excellence Award (SETEA) in 2024 under the “Advancement of SE” category. Nipa’s out-of-the-box thinking has also positioned her as a trailblazer amongst her peers. “Nipa was ahead of everyone in terms of understanding what Digital Transformation is,” says Ian Levitt, Concepts Team Manager at Langley Research Center and co-lead on the Requirement Discovery Prototype Test. “She is extremely smart as well as practical, which is a rare combination. She has wonderful insights and helps me see more clearly what I am trying to do.” As a leader in the Digital Transformation community, Nipa recognizes the importance of collaboration, noting that her transformative work would not have been successful without her team. Their trust is what makes her ideas possible, along with Digital Transformation’s willingness to take chances on innovative, cutting-edge ideas. “They’re at the forefront of technology, so they’re receptive to high-risk projects,” she says. “That’s why I enjoy working with the Digital Transformation team.” 
      In turn, Nipa is excited to continue building community and momentum around transformation initiatives. Her team’s work inspired one group at Johnson Space Center to replicate their requirement discovery approach, and she has received multiple inquiries for demos on their prototype. Seeing how her work inspires and impacts others at the agency is one way she measures success. Whether she is connecting data sources or people, Nipa continues to push toward a more unified NASA, exemplifying what it means to be a digital transformer.
