Sarafin discussed lessons learned from Artemis I, highlighting the importance of communicating quickly and effectively with team members and using risk informed decision-making tools. After some initial delays that included lightning strikes, the Artemis I mission began with a successful liftoff of NASA’s SLS (Space Launch System) rocket Nov. 16, 2022, from Launch Pad 39B at NASA’s Kennedy Space Center. Over the course of 25.5 days, NASA tested the Orion spacecraft in the harsh environment of deep space before flying astronauts on Artemis II.

Sarafin said it was his first time in the “hot seat,” and stressed the importance for anyone leading a mission management team to prepare for it by talking with those who have been in the same role, naming the individuals who supported him as team chair.

“You have got to find somebody who has walked a mile in those shoes, who understands the dynamics, who understands the cultural aspects of it,” Sarafin said. “They were fantastic team members, fantastic partners to work with, and I am proud to be a part of that team. These guys walked alongside me and kept me out of trouble.”

As Artemis mission manager for the Moon to Mars Program Office at NASA Headquarters, Sarafin provides oversight and responsibility for critical decisions across all flight phases (launch, in-space, and recovery), with support from team members and advisers with technical expertise in various areas. Prior to flight, he acts as a senior technical leader integrating mission requirements, planning, operations, and flight readiness leading to mission execution.

Sarafin said lessons learned from the mission management team for Artemis I included training both a prime and alternate for each position. He also pointed out the importance of training for logistics, and daily effective communications for all team members.

“In summary, have the right team, do your party planning, (and) set clear expectations,” Sarafin said. “Take care of yourself and your team, and use good tools to make decisions.”

Mission Success is in Our Hands is a safety initiative collaboration between NASA’s Marshall Space Flight Center and Jacobs Engineering. The initiative’s goal is to help team members make meaningful connections between their jobs and the safety and success of NASA and Marshall missions.

Charlie Adams Presented with Golden Eagle Award

As part of the forum, Mission Success is in Our Hands presented the 40th Golden Eagle Award to Charlie Adams of the Jacobs Space Exploration Group. Adams was the mission manager for NASA’s Low-Earth Orbit Flight Test of an Inflatable Decelerator (LOFTID).

Bill Hill, director of Safety and Mission Assurance at Marshall, said Adams was recognized for leading the project throughout LOFTID’s life cycle, which culminated with a successful flight in 2022. Hill said LOFTID’s success as a heat shield will benefit NASA’s future missions.

The Golden Eagle Award promotes awareness and appreciation for flight safety, as demonstrated through the connections between employees’ everyday work, the success of NASA and Marshall’s missions, and the safety of NASA astronauts. Management or peers can nominate any team member for the award. Honorees are typically recognized at Shared Experiences forums.

The next Shared Experiences Forum is scheduled for Sept. 5, featuring Dave Dykhoff, former vice president and general manager of the Jacobs Missile Defense Group and the North American Aerospace Defense (NORAD) Operations Group. The forum will be held in Building 4203, Conference Room 1201 for Marshall team members, and available to the public via Teams.

I Am Artemis: Julia Khodabandeh

Unlike most of her friends in the 80s who covered their walls with posters of bands, Julia Khodabandeh plastered hers with posters of rockets and fighter jets.

Khodabandeh’s interest in aerospace and aeronautics developed at a young age. Her parents were avid fans of the Apollo Program and were heavily invested in her education. Khodabandeh’s father always encouraged her to tackle math and science problems without fear. She recalls him telling her that “you can take any problem and break it into smaller pieces.” It’s a philosophy she still uses in solving problems today.

Julia Khodabandeh once adorned her walls with rockets, fighter jets, and Air Force pilots. Now, she is the solid rocket motor lead for NASA’s SLS (Space Launch System).
NASA/Sam Lott

“When I was growing up, my dad would make practice tests the night before my exams,” she said. “It helped me feel more prepared. The confidence I developed for math and science and my passion for aeronautics and aerospace, led me to a NASA career.”

The better part of her 24-year career with NASA has been dedicated to solid rocket boosters at the agency’s Marshall Space Flight Center. Over the past 10 years, she helped develop the twin solid rocket boosters for the agency’s SLS (Space Launch System) rocket, which are the largest and most powerful solid propellant boosters ever flown. They stand at 177 feet tall, and individually generate a maximum thrust of 3.6 million pounds. Together, the twin boosters provide more than 75% of the total thrust to launch SLS for NASA’s Artemis campaign to the Moon.

Khodabandeh graduated from the University of Alabama in Huntsville with a bachelor’s degree in mechanical engineering and a master’s degree in computational fluid dynamics. Early in her career, her work focused on Space Station microgravity material processing furnaces and the Space Shuttle Return-to-Flight Program.  She went on to support the Ares rocket solid rocket booster team as part of the Constellation Program preceding SLS. Her work on the Ares booster helped guide her to her current position on SLS.

Khodabandeh is the motor and pyrotechnic team lead for the SLS Booster Element Office. She supports design, development, certification, production, and operation of the solid rocket motors, booster separation motors, and pyrotechnics for the twin boosters on SLS. Most days, she manages schedules and helps resolve issues with the help of her team.

“The flight hardware and test hardware are all tremendous accomplishments for the team, and behind these accomplishments are hours, weeks, and months of working together to resolve issues and deliver results,” Khodabandeh said. “It’s the people that make us successful, and teamwork is my favorite part of what we do. Someone once said, ‘You have to build a successful team before you can build successful hardware.’ I couldn’t agree more!”

In her spare time, Khodabandeh volunteers at a local rescue mission, where she provides aid to women struggling with substance abuse. She also mentors students in the Huntsville community, where she hopes to pass on the confidence her dad instilled in her, inspiring them to one day be a part of NASA and the Artemis Generation.

As the girl who grew up with posters of rockets on her walls, Khodabandeh says she is incredibly excited to be one of the many who are responsible for sending astronauts around the Moon on Artemis II.

“The incredible success of Artemis I is something that I will never forget,” she said. “We have demonstrated what we’re capable of, and I can’t wait to see what we accomplish going forward on the Artemis Program.”

NASA is working to land the first woman, first person of color, and its first international partner astronaut on the Moon under Artemis. SLS is part of NASA’s backbone for deep space exploration, along with the Orion spacecraft, supporting ground systems, advanced spacesuits and rovers, the Gateway in orbit around the Moon, and commercial human landing systems. SLS is the only rocket that can send Orion, astronauts, and supplies to the Moon in a single launch.

A ‘FURST’ of its Kind: Sounding Rocket Mission to Study Sun as a Star

Editor’s Note: NASA and partners scrubbed the first launch attempt of the FURST Sounding Rocket Mission on Aug. 11 due to issues with the cooling systems. This story will be updated as soon as the next launch attempt is determined.

By Jessica Barnett 

From Earth, one might be tempted to view the Sun as a unique celestial object like no other, as it’s the star our home planet orbits and the one our planet relies on most for heat and light. But if you took a step back and compared the Sun to the other stars NASA has studied over the years, how would it compare? Would it still be so unique?

furst-2.jpg?w=1412
The Full-sun Ultraviolet Rocket SpecTrograph (FURST) undergoes testing at White Sands Missile Range in New Mexico in preparation for launch. The instrument was designed and built at Montana State University. NASA’s Marshall Space Flight Center provided the camera, supplied avionics, and designed and built its calibration system.

The Full-sun Ultraviolet Rocket SpecTrograph (FURST) aims to answer those questions. when it launches aboard a Black Brant IX sounding rocket at White Sands Missile Range in New Mexico.

“When we talk about ‘Sun as a star’, we’re treating it like any other star in the night sky as opposed to the unique object we rely on for human life. It’s so exciting to study the Sun from that vantage point,” said Adam Kobelski, institutional principal investigator for FURST and a research astrophysicist at NASA’s Marshall Space Flight Center.

FURST will obtain the first high-resolution spectra of the “Sun as a star” in vacuum ultraviolet (VUV), a light wavelength that is absorbed in Earth’s atmosphere meaning it can only be observed from space. Astronomers have studied other stars in the vacuum ultraviolet with orbiting telescopes, however these instruments are too sensitive to be pointed to the Sun. The recent advancements in high-resolution VUV spectroscopy now allow for the same observations of our own star, the Sun.

“These are wavelengths that Hubble Space Telescope is really great at observing, so there is a decent amount of Hubble observations of stars in ultraviolet wavelengths, but we don’t have comparable observations of our star in this wavelength range,” said Kobelski. Marshall was the lead field center for the design, development, and construction of the Hubble Space Telescope.

Because Hubble is too sensitive to point at Earth’s Sun, new instruments were needed to get a spectrum of the entire Sun that is of a similar quality to Hubble’s observations of other stars. Marshall built the camera, supplied avionics, and designed and built a new calibration system for the FURST mission. Montana State University (MSU), which leads the FURST mission in partnership with Marshall, built the optical system, which includes seven optics that will feed into the camera that will essentially create seven exposures, covering the entire ultraviolet wavelength range.

Charles Kankelborg, a heliophysics professor at MSU and principal investigator for FURST, described the mission as a very close collaboration with wide-ranging implications.

“Our mission will obtain the first far ultraviolent spectrum of the Sun as a star,” Kankelborg said. “This is a key piece of information that has been missing for decades. With it, we will place the Sun in context with other stars.”

Kobelski echoed the sentiment.

“How well do the observations and what we know about our Sun compare to our observations or what we know of other stars?” Kobelski said. “You’d expect that we know all this information about the Sun – it’s right there – but it turns out, we actually don’t. If we can get these same observations or same wavelengths as we’ve observed from these other sources, we can start to connect the dots and connect our Sun to other stars.”

FURST will be the third launch led by Marshall for NASA’s Sounding Rocket Program within five months, making 2024 an active year for the program. Like the Hi-C Flare mission that launched in April, the sounding rocket will launch and open during flight to allow FURST to observe the Sun for approximately five minutes before closing and falling back to Earth’s surface. Marshall team members will be able to calibrate the instruments during launch and flight, as well as retrieve data during flight and soon after landing.

Kobelski and Kankelborg each said they’re grateful for the opportunity to fill the gaps in our knowledge of Earth’s Sun.

The FURST mission is led by Marshall in partnership with Montana State University in Bozeman, Montana, with additional support from the NASA’s Sounding Rockets Office and the U.S. National Center for Atmospheric Research’s High Altitude Observatory. Launch support is provided at White Sands Missile Range in New Mexico by NASA’s Johnson Space Center. NASA’s Sounding Rocket Program is managed by the agency’s Heliophysics Division.

NASA Challenge Seeks ‘Cooler’ Solutions for Deep Space Exploration

NASA’s Human Lander Challenge, or HuLC, is now open and accepting submissions for its second year. As NASA aims to return astronauts to the Moon through its Artemis campaign in preparation for future missions to Mars, the agency is seeking ideas from college and university students for evolved supercold, or cryogenic, propellant applications for human landing systems.

Human Lander Challenge (HuLC) banner.

As part of the 2025 HuLC competition, teams will aim to develop innovative solutions and technology developments for in-space cryogenic liquid storage and transfer systems as part of future long-duration missions beyond low Earth orbit.

“The HuLC competition represents a unique opportunity for Artemis Generation engineers and scientists to contribute to groundbreaking advancements in space technology,” said Esther Lee, an aerospace engineer leading the navigation sensors technology assessment capability team at NASA’s Langley Research Center. “NASA’s Human Lander Challenge is more than just a competition – it is a collaborative effort to bridge the gap between academic innovation and practical space technology. By involving students in the early stages of technology development, NASA aims to foster a new generation of aerospace professionals and innovators.”

Through Artemis, NASA is working to send the first woman, first person of color, and first international partner astronaut to the Moon to establish long-term lunar exploration and science opportunities. Artemis astronauts will descend to the lunar surface in a commercial Human Landing System. The Human Landing System Program is managed by NASA’s Marshall Space Flight Center.

Cryogenic, or super-chilled, propellants like liquid hydrogen and liquid oxygen are integral to NASA’s future exploration and science efforts. The temperatures must stay extremely cold to maintain a liquid state. Current state-of-the-art systems can only keep these substances stable for a matter of hours, which makes long-term storage particularly problematic. For NASA’s HLS mission architecture, extending storage duration from hours to several months will help ensure mission success.

“NASA’s cryogenics work for HLS focuses on several key development areas, many of which we are asking proposing teams to address,” said Juan Valenzuela, a HuLC technical advisor and aerospace engineer specializing in cryogenic fuel management at Marshall. “By focusing research in these key areas, we can explore new avenues to mature advanced cryogenic fluid technologies and discover new approaches to understand and mitigate potential problems.”

Interested teams from U.S.-based colleges and universities should submit a non-binding Notice of Intent (NOI) by Oct. 6, and submit a proposal package by March 3, 2025. Based on proposal package evaluations, up to 12 finalist teams will be selected to receive a $9,250 stipend to further develop and present their concepts to a panel of NASA and industry judges at the 2025 HuLC Forum in Huntsville, near Marshall, in June 2025. The top three placing teams will share a prize purse of $18,000.

Teams’ potential solutions should focus on one of the following categories: On-Orbit Cryogenic Propellant Transfer, Microgravity Mass Tracking of Cryogenics, Large Surface Area Radiative Insulation, Advanced Structural Supports for Heat Reduction, Automated Cryo-Couplers for Propellant Transfer, or Low Leakage Cryogenic Components.

NASA’s Human Lander Challenge is sponsored by the Human Landing System Program within the Exploration Systems Development Mission Directorate and managed by the National Institute of Aerospace.

Webb Sees Gassy Baby Stars

NASA’s James Webb Space Telescope has captured a phenomenon for the very first time. The bright red streaks at top left of this June 20 image are aligned protostar outflows – jets of gas from newborn stars that all slant in the same direction.

A rectangular image with black vertical rectangles at the bottle left and top right to indicate missing data. A young star-forming region is filled with wispy orange, red, and blue layers of gas and dust. The upper left corner of the image is filled with mostly orange dust, and within that orange dust, there are several small red plumes of gas that extend from the top left to the bottom right, at the same angle. The center of the image is filled with mostly blue gas. At the center, there is one particularly bright star, that has an hourglass shadow above and below it. To the right of that is what looks a vertical eye-shaped crevice with a bright star at the center. The gas to the right of the crevice is a darker orange. Small points of light are sprinkled across the field, brightest sources in the field have extensive eight-pointed diffraction spikes that are characteristic of the Webb Telescope.
In this image of the Serpens Nebula from NASA’s James Webb Space Telescope, astronomers found a grouping of aligned protostellar outflows within one small region (the top left corner). Serpens is a reflection nebula, which means it’s a cloud of gas and dust that does not create its own light, but instead shines by reflecting the light from stars close to or within the nebula.
NASA, ESA, CSA, STScI, Klaus Pontoppidan (NASA-JPL), Joel Green (STScI)

This image supports astronomers’ assumption that as clouds collapse to form stars, the stars will tend to spin in the same direction. Previously, the objects appeared as blobs or were invisible in optical wavelengths. Webb’s sensitive infrared vision was able to pierce through the thick dust, resolving the stars and their outflows.

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

      Hubble Studies a Nearby Galaxy’s Star Formation
      This NASA/ESA Hubble Space Telescope image features the picturesque spiral galaxy NGC 4941. ESA/Hubble & NASA, D. Thilker This NASA/ESA Hubble Space Telescope image features the picturesque spiral galaxy NGC 4941, which lies about 67 million light-years from Earth in the constellation Virgo (The Maiden). Because this galaxy is nearby, cosmically speaking, Hubble’s keen instruments are able to pick out exquisite details such as individual star clusters and filamentary clouds of gas and dust.
      The data used to construct this image were collected as part of an observing program that investigates the star formation and stellar feedback cycle in nearby galaxies. As stars form in dense, cold clumps of gas, they begin to influence their surroundings. Stars heat and stir up the gas clouds in which they form through winds, starlight, and — eventually, for massive stars — by exploding as supernovae. These processes are collectively called stellar feedback, and they influence the rate at which a galaxy can form new stars.
      As it turns out, stars aren’t the only entities providing feedback in NGC 4941. At the heart of this galaxy lies an active galactic nucleus: a supermassive black hole feasting on gas. As the black hole amasses gas from its surroundings, the gas swirls into a superheated disk that glows brightly at wavelengths across the electromagnetic spectrum. Similar to stars — but on a much, much larger scale — active galactic nuclei shape their surroundings through winds, radiation, and powerful jets, altering not only star formation but also the evolution of the galaxy as a whole.

      Image: This image shows Webb’s recent observation of the asteroid 2024 YR4 using both its Near-Infrared Camera (NIRCam) and Mid-Infrared Instrument (MIRI). Data from NIRCam shows reflected light, while the MIRI observations show thermal light.
      On 8 March 2025, the NASA/ESA/CSA James Webb Space Telescope turned its watchful eye toward asteroid 2024 YR4, which we now know poses no significant threat to Earth in 2032 and beyond.
      This is the smallest object targeted by Webb to date, and one of the smallest objects to have its size directly measured.
      Observations were taken to study the thermal properties of 2024 YR4, including how quickly it heats up and cools down and how hot it is at its current distance from the Sun. These measurements indicate that this asteroid does not share properties observed in larger asteroids. This is likely a combination of its fast spin and lack of fine-grained sand on its surface. Further research is needed, however this is considered consistent with a surface dominated by rocks that are roughly fist-sized or larger.
      Asteroid 2024 YR4 was recently under close watch by the team at ESA's Near Earth Objects Coordination Centre, located in Italy. Planetary defence experts from the Agency's Space Safety programme worked with NASA and the international asteroid community to closely watch this object and refine its orbit, which was eventually determined to not pose a risk of Earth impact. Read details on this unusual campaign via ESA's Rocket Science blog and in news articles here and here.
      Webb’s observations indicate that the asteroid measures roughly 60 meters (comparable to the height of a 15-story building).
      The new observations from Webb not only provide unique information about 2024 YR4’s size, but can also complement ground-based observations of the object's position to help improve our understanding of the object’s orbit and future trajectory.
      Note: This post highlights data from Webb science in progress, which has not yet been through the peer-review process.

      NASA, ESA, CSA, STScI, SARAO, Samuel Crowe (UVA), John Bally (CU), Ruben Fedriani (IAA-CSIC), Ian Heywood (Oxford) Follow-up research on a 2023 image of the Sagittarius C stellar nursery in the heart of our Milky Way galaxy, captured by NASA’s James Webb Space Telescope, has revealed ejections from still-forming protostars and insights into the impact of strong magnetic fields on interstellar gas and the life cycle of stars.  
      “A big question in the Central Molecular Zone of our galaxy has been, if there is so much dense gas and cosmic dust here, and we know that stars form in such clouds, why are so few stars born here?” said astrophysicist John Bally of the University of Colorado Boulder, one of the principal investigators. “Now, for the first time, we are seeing directly that strong magnetic fields may play an important role in suppressing star formation, even at small scales.”
      Detailed study of stars in this crowded, dusty region has been limited, but Webb’s advanced near-infrared instruments have allowed astronomers to see through the clouds to study young stars like never before.
      “The extreme environment of the galactic center is a fascinating place to put star formation theories to the test, and the infrared capabilities of NASA’s James Webb Space Telescope provide the opportunity to build on past important observations from ground-based telescopes like ALMA and MeerKAT,” said Samuel Crowe, another principal investigator on the research, a senior undergraduate at the University of Virginia and a 2025 Rhodes Scholar.
      Bally and Crowe each led a paper published in The Astrophysical Journal.

The spectral index at the lower left shows how color was assigned to the radio data to create the image. On the negative end, there is non-thermal emission, stimulated by electrons spiraling around magnetic field lines. On the positive side, thermal emission is coming from hot, ionized plasma. For Webb, color is assigned by shifting the infrared spectrum to visible light colors. The shortest infrared wavelengths are bluer, and the longer wavelengths appear more red.

      In Sagittarius C’s brightest cluster, the researchers confirmed the tentative finding from the Atacama Large Millimeter Array (ALMA) that two massive stars are forming there. Along with infrared data from NASA’s retired Spitzer Space Telescope and SOFIA (Stratospheric Observatory for Infrared Astronomy) mission, as well as the Herschel Space Observatory, they used Webb to determine that each of the massive protostars is already more than 20 times the mass of the Sun. Webb also revealed the bright outflows powered by each protostar.
      Even more challenging is finding low-mass protostars, still shrouded in cocoons of cosmic dust. Researchers compared Webb’s data with ALMA’s past observations to identify five likely low-mass protostar candidates.
      The team also identified 88 features that appear to be shocked hydrogen gas, where material being blasted out in jets from young stars impacts the surrounding gas cloud. Analysis of these features led to the discovery of a new star-forming cloud, distinct from the main Sagittarius C cloud, hosting at least two protostars powering their own jets.
      “Outflows from forming stars in Sagittarius C have been hinted at in past observations, but this is the first time we’ve been able to confirm them in infrared light. It’s very exciting to see, because there is still a lot we don’t know about star formation, especially in the Central Molecular Zone, and it’s so important to how the universe works,” said Crowe.
      Magnetic Fields and Star Formation
      Webb’s 2023 image of Sagittarius C showed dozens of distinctive filaments in a region of hot hydrogen plasma surrounding the main star-forming cloud. New analysis by Bally and his team has led them to hypothesize that the filaments are shaped by magnetic fields, which have also been observed in the past by the ground-based observatories ALMA and MeerKAT (formerly the Karoo Array Telescope).
      “The motion of gas swirling in the extreme tidal forces of the Milky Way’s supermassive black hole, Sagittarius A*, can stretch and amplify the surrounding magnetic fields. Those fields, in turn, are shaping the plasma in Sagittarius C,” said Bally.
      The researchers think that the magnetic forces in the galactic center may be strong enough to keep the plasma from spreading, instead confining it into the concentrated filaments seen in the Webb image. These strong magnetic fields may also resist the gravity that would typically cause dense clouds of gas and dust to collapse and forge stars, explaining Sagittarius C’s lower-than-expected star formation rate. 
      “This is an exciting area for future research, as the influence of strong magnetic fields, in the center of our galaxy or other galaxies, on stellar ecology has not been fully considered,” said Crowe.  
      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).

      X-ray: NASA/CXC/Technion/N. Keshet et al.; Illustration: NASA/CXC/SAO/M. Weiss People often think about archaeology happening deep in jungles or inside ancient pyramids. However, a team of astronomers has shown that they can use stars and the remains they leave behind to conduct a special kind of archaeology in space.
      Mining data from NASA’s Chandra X-ray Observatory, the team of astronomers studied the relics that one star left behind after it exploded. This “supernova archaeology” uncovered important clues about a star that self-destructed – probably more than a million years ago.
      Today, the system called GRO J1655-40 contains a black hole with nearly seven times the mass of the Sun and a star with about half as much mass. However, this was not always the case.
      Originally GRO J1655-40 had two shining stars. The more massive of the two stars, however, burned through all of its nuclear fuel and then exploded in what astronomers call a supernova. The debris from the destroyed star then rained onto the companion star in orbit around it, as shown in the artist’s concept.
      This artist’s impression shows the effects of the collapse and supernova explosion of a massive star. A black hole (right) was formed in the collapse and debris from the supernova explosion is raining down onto a companion star (left), polluting its atmosphere.CXC/SAO/M. Weiss With its outer layers expelled, including some striking its neighbor, the rest of the exploded star collapsed onto itself and formed the black hole that exists today. The separation between the black hole and its companion would have shrunk over time because of energy being lost from the system, mainly through the production of gravitational waves. When the separation became small enough, the black hole, with its strong gravitational pull, began pulling matter from its companion, wrenching back some of the material its exploded parent star originally deposited.
      While most of this material sank into the black hole, a small amount of it fell into a disk that orbits around the black hole. Through the effects of powerful magnetic fields and friction in the disk, material is being sent out into interstellar space in the form of powerful winds.
      This is where the X-ray archaeological hunt enters the story. Astronomers used Chandra to observe the GRO J1655-40 system in 2005 when it was particularly bright in X-rays. Chandra detected signatures of individual elements found in the black hole’s winds by getting detailed spectra – giving X-ray brightness at different wavelengths – embedded in the X-ray light. Some of these elements are highlighted in the spectrum shown in the inset.
      The team of astronomers digging through the Chandra data were able to reconstruct key physical characteristics of the star that exploded from the clues imprinted in the X-ray light by comparing the spectra with computer models of stars that explode as supernovae. They discovered that, based on the amounts of 18 different elements in the wind, the long-gone star destroyed in the supernova was about 25 times the mass of the Sun, and was much richer in elements heavier than helium in comparison with the Sun.
      This analysis paves the way for more supernova archaeology studies using other outbursts of double star systems.
      A paper describing these results titled “Supernova Archaeology with X-Ray Binary Winds: The Case of GRO J1655−40” was published in The Astrophysical Journal in May 2024. The authors of this study are Noa Keshet (Technion — Israel Institute of Technology), Ehud Behar (Technion), and Timothy Kallman (NASA’s Goddard Space Flight Center).

      Visual Description
      This release features an artist’s rendering of a supernova explosion, inset with a spectrum graph.
      The artist’s illustration features a star and a black hole in a system called GRO J1655-40. Here, the black hole is represented by a black sphere to our upper right of center. The star is represented by a bright yellow sphere to our lower left of center. In this illustration, the artist captures the immensely powerful supernova as a black hole is created from the collapse of a massive star, with an intense burst of blurred beams radiating from the black sphere. The blurred beams of red, orange, and yellow light show debris from the supernova streaking across the entire image in rippling waves. These beams rain debris on the bright yellow star.
      When astronomers used the Chandra X-ray Observatory to observe the system in 2005, they detected signatures of individual elements embedded in the X-ray light. Some of those elements are highlighted in the spectrum graph shown in the inset, positioned at our upper lefthand corner.
      The graph’s vertical axis, on our left, indicates X-ray brightness from 0.0 up to 0.7 in intensity units. The horizontal axis, at the bottom of the graph, indicates Wavelength from 6 to 12 in units of Angstroms. On the graph, a tight zigzagging line begins near the top of the vertical axis, and slopes down toward the far end of the horizontal axis. The sharp dips show wavelengths where the light has been absorbed by different elements, decreasing the X-ray brightness. Some of the elements causing these dips have been labeled, including Silicon, Magnesium, Iron, Nickel, Neon, and Cobalt.

      The innovative team of engineers and scientists from NASA, the Johns Hopkins Applied Physics Laboratory in Laurel, Maryland, and more than 40 other partner organizations across the country that created the Parker Solar Probe mission has been awarded the 2024 Robert J. Collier Trophy by the National Aeronautic Association (NAA). This annual award recognizes the most exceptional achievement in aeronautics and astronautics in America with respect to improving the performance, efficiency, and safety of air or space vehicles in the previous year.   
      “Congratulations to the entire Parker Solar Probe team for this well-earned recognition,” said NASA acting Administrator Janet Petro. “This mission’s trailblazing research is rewriting the textbooks on solar science by going to a place no human-made object has ever been and advancing NASA’s efforts to better understand our solar system and the Sun’s influence, with lasting benefits for us all. As the first to touch the Sun and fastest human-made object ever built, Parker Solar Probe is a testament to human ingenuity and discovery.”
      An artist’s concept of NASA’s Parker Solar Probe. NASA On Dec. 24, 2024, Parker Solar Probe made its closest approach to the Sun, passing deep within the Sun’s corona, just 3.8 million miles above the Sun’s surface and at a top speed of close to 430,000 mph, ushering in a new era of scientific discovery and space exploration.
      “This award is a recognition of the unrelenting dedication and hard work of the Parker Solar Probe team. I am so proud of this team and honored to have been a part of it,” said Nicky Fox, associate administrator, Science Mission Directorate, NASA Headquarters in Washington. “By studying the Sun closer than ever before, we continue to advance our understanding of not only our closest star, but also stars across our universe. Parker Solar Probe’s historic close approaches to the Sun are a testament to the incredible engineering that made this record-breaking journey possible.”
      Three novel aerospace technology advancements were critical to enabling this record performance: The first is the Thermal Protection System, or heat shield, that protects the spacecraft and is built to withstand brutal temperatures as high as 2,500 degrees Fahrenheit. The Thermal Protection System allows Parker’s electronics and instruments to operate close to room temperature.
      Additional Parker innovations included first-of-their-kind actively cooled solar arrays that protect themselves from overexposure to intense solar energy while powering the spacecraft, and a fully autonomous spacecraft system that can manage its own flight behavior, orientation, and configuration for months at a time. Parker has relied upon all of these vital technologies every day since its launch almost seven years ago, in August 2018.
      “I am thrilled for the Parker Solar Probe team on receiving this well-deserved award,” said Joe Westlake, director of the Heliophysics Division at NASA Headquarters. “The new information about the Sun made available through this mission will improve our ability to prepare for space weather events across the solar system, as well as better understand the very star that makes life possible for us on Earth.”
      Parker’s close-up observations of solar events, such as coronal mass ejections and solar particle events, are critical to advancing our understanding of the science of our Sun and the phenomena that drive high-energy space weather events that pose risks to satellites, air travel, astronauts, and even power grids on Earth. Understanding the fundamental physics behind events which drive space weather will enable more reliable predictions and lower astronaut exposure to hazardous radiation during future deep space missions to the Moon and Mars.
      “This amazing team brought to life an incredibly difficult space science mission that had been studied, and determined to be impossible, for more than 60 years. They did so by solving numerous long-standing technology challenges and dramatically advancing our nation’s spaceflight capabilities,” said APL Director Ralph Semmel. “The Collier Trophy is well-earned recognition for this phenomenal group of innovators from NASA, APL, and our industry and research partners from across the nation.”
      First awarded in 1911, the Robert J. Collier Trophy winner is selected by a group of aviation leaders chosen by the NAA. The Collier Trophy is housed in the Smithsonian’s National Air and Space Museum in Washington.
      “Traveling three times closer to the Sun and seven times faster than any spacecraft before, Parker’s technology innovations enabled humanity to reach inside the Sun’s atmosphere for the first time,” said Bobby Braun, head of APL’s Space Exploration Sector. “We are all immensely proud that the Parker Solar Probe team will join a long legacy of prestigious aerospace endeavors that redefined technology and changed history.”
      “The Parker Solar Probe team’s achievement in earning the 2024 Collier is a shining example of determination, genius, and teamwork,” said NAA President and CEO Amy Spowart. “It’s a distinct honor for the NAA to acknowledge and celebrate the remarkable team that turned the impossible into reality.”
      Parker Solar Probe was developed as part of NASA’s Living With a Star program to explore aspects of the Sun-Earth system that directly affect life and society. The Living With a Star program is managed by the agency’s Goddard Space Flight Center in Greenbelt, Maryland, for NASA’s Science Mission Directorate in Washington. The Applied Physics Laboratory designed, built, and operates the spacecraft and manages the mission for NASA.
