California Teams Win $1.5 Million in NASA’s Break the Ice Lunar Challenge

By Savannah Bullard

After two days of live competitions, two teams from southern California are heading home with a combined $1.5 million from NASA’s Break the Ice Lunar Challenge

Since 2020, competitors from around the world have competed in this challenge with the common goal of inventing robots that can excavate and transport the icy regolith on the Moon. The lunar South Pole is the targeted landing site for crewed Artemis missions, so utilizing all resources in that area, including the ice within the dusty regolith inside the permanently shadowed regions, is vital for the success of a sustained human lunar presence.

On Earth, the mission architectures developed in this challenge aim to help guide machine design and operation concepts for future mining and excavation operations and equipment for decades.

“Break the Ice represents a significant milestone in our journey toward sustainable lunar exploration and a future human presence on the Moon,” said Joseph Pelfrey, center director of NASA’s Marshall Space Flight Center. “This competition has pushed the boundaries of what is possible by challenging the brightest minds to devise groundbreaking solutions for excavating lunar ice, a crucial resource for future missions. Together, we are forging a future where humanity ventures further into the cosmos than ever before.”

The final round of the Break the Ice competition featured six finalist teams who succeeded in an earlier phase of the challenge. The competition took place at the Alabama A&M Agribition Center in Huntsville on June 11 and 12, where each team put their diverse solutions to the test in a series of trials, using terrestrial resources like gravity-offloading cranes, concrete slabs, and a rocky track with tricky obstacles to mimic the environment on the Moon.

The husband-and-wife duo of Terra Engineering took home the top prize for their “Fracture” rover. Team lead Todd Mendenhall competed in NASA’s 2007 Regolith Excavation Challenge, facilitated through NASA’s Centennial Challenges, which led him and Valerie Mendenhall to continue the pursuit of solutions for autonomous lunar excavation.

A small space hardware business, Starpath Robotics, earned the second-place prize for its four-wheeled rover that can mine, collect, and haul material. The team, led by Saurav Shroff and lead engineer Mihir Gondhalekar, developed a robotic mining tool that features a drum barrel scraping mechanism for breaking into the tough lunar surface. This allows the robot to mine material quickly and robustly without sacrificing energy.

“This challenge has been pivotal in advancing the technologies we need to achieve a sustained human presence on the Moon,” said Kim Krome, the Acting Program Manager for NASA’s Centennial Challenges. “Terra Engineering’s rover, especially, bridged several of the technology gaps that we identified – for instance, being robust and resilient enough to traverse rocky landscapes and survive the harsh conditions of the lunar South Pole.”

Beyond the $1.5 million in prize funds, three teams will be given the chance to use Marshall Space Flight Center’s thermal vacuum (TVAC) chambers to continue testing and developing their robots. These chambers use thermal vacuum technologies to create a simulated lunar environment, allowing scientists and researchers to build, test, and approve hardware for flight-ready use.

The following teams performed exceptionally well in the excavation portion of the final competition, earning these invitations to the TVAC facilities:

  • Terra Engineering (Gardena, California)
  • Starpath Robotics (Hawthorne, California)
  • Michigan Technological University – Planetary Surface Technology Development Lab (Houghton, Michigan)

“We’re looking forward to hosting three of our finalists at our thermal vacuum chamber, where they will get full access to continue testing and developing their technologies in our state-of-the-art facilities,” said Break the Ice Challenge Manager Naveen Vetcha, who supports NASA’s Centennial Challenges through Jacobs Space Exploration Group. “Hopefully, these tests will allow the teams to take their solutions to the next level and open the door for opportunities for years to come.”

NASA’s Break the Ice Lunar Challenge is a NASA Centennial Challenge led by the agency’s Marshall Space Flight Center, with support from NASA’s Kennedy Space Center. Centennial Challenges are part of the Prizes, Challenges, and Crowdsourcing program under NASA’s Space Technology Mission Directorate. Ensemble Consultancy supports challenge competitors. Alabama A&M University, in coordination with NASA, supports the final competitions and winner event for the challenge.

Mission Success is in Our Hands: Baraka Truss

By Wayne Smith

Mission Success is in Our Hands is a safety initiative collaboration between NASA’s Marshall Space Flight Center and Jacobs. As part of the initiative, eight Marshall team members are featured in testimonial banners placed around the center. This is the last in a Marshall Star series profiling team members featured in the testimonial banners. The Mission Success team also awards the Golden Eagle Award on a quarterly basis to Marshall and contractor personnel who are nominated by their peers or management. Candidates for this award have made significant, identifiable contributions that exceed normal job expectations to advance flight safety and mission assurance. Nominations for 2024 are open now online on Inside Marshall.

Baraka Truss is the Avionics and Software Branch chief at NASA’s Marshall Space Flight Center.

Baraka Truss is the Avionics and Software Branch chief in the Safety and Mission Assurance Organization, Vehicle Systems Department, at NASA’s Marshall Space Flight Center. Her key responsibilities include being viewed as a leadership role model, “demonstrating commitment to the mission and NASA’s core values, creating the most impact for the greater agency, and engaging in activities that promote supervisory excellence and value beyond the immediate organization.”

Truss has worked at Marshall for 28 years. Her previous roles have been software engineer, Software Engineering Process Group lead, special assistant to the center director, Independent Assessment Team lead, Software Quality Discipline lead engineer, Software Assurance Team lead, and     SLS (Space Launch System) Software chief safety officer.

A native of Montgomery, Alabama, Truss earned a bachelor’s and master’s degree in computer science from Alabama A&M University in Huntsville.

Question: How does your work support the safety and success of NASA and Marshall missions?

Truss: My work involves daily managing and interactions with the avionics and software team members whose mission is to ensure the safety of hardware and software for various programs and projects at Marshall and NASA.

Question: What does the initiative campaign “Mission Success is in Our Hands” mean to you?

Truss: That when risks arise, we should be sure to listen to all sides and make informed decisions, be held accountable, and speak up for what is safe when we need to do so.

Question: Do you have a story or personal experience you can share that might help others understand the significance of mission assurance or flight safety? What did you learn from it?

Truss: In my experience, mission assurance requires you to “believe the unlikely.” I have learned that believing what you have never seen requires you to stretch your imagination, because we are prone to discount and devalue things that we have not seen. We are skeptical about things that have never been seen, never been done, never been achieved, or never been accomplished.

Because according to our limited logic if it’s never been seen, never been done, never been achieved, or never been accomplished, then it’s not likely to be seen, not likely to be done, not likely to be achieved, and not likely to be accomplished. Therefore, we see no need to attempt it, try it, believe it, or invest in it because while we’ll acknowledge that it’s possible, we quickly add it’s not probable, because our idea of likelihood is limited by our experience. My experiences working for NASA have stretched me to an amazing place of accountability, assurance, and mission success.

Question: How can we work together better to achieve mission success?

Truss: Again, by listening to all sides and making informed decisions, being held accountable, and speaking up for what is safe when we need to do so.

Coming in Hot: NASA’s Chandra Checks Habitability of Exoplanets

This graphic shows a three-dimensional map of stars near the Sun. These stars are close enough that they could be prime targets for direct imaging searches for planets using future telescopes. The blue haloes represent stars that have been observed with NASA’s Chandra X-ray Observatory and ESA’s XMM-Newton. The yellow star at the center of this diagram represents the position of the Sun. The concentric rings show distances of 5, 10, and 15 parsecs (one parsec is equivalent to roughly 3.2 light-years).

Astronomers are using these X-ray data to determine how habitable exoplanets may be based on whether they receive lethal radiation from the stars they orbit, as described in a press release. This type of research will help guide observations with the next generation of telescopes aiming to make the first images of planets like Earth.

This video shows a three-dimensional map of stars near the Sun on the left side of the screen and a dramatic illustration of a star with a planet orbiting around it on the right side.
Movie: Cal Poly Pomona/B. Binder; Illustration: NASA/CXC/M.Weiss

Researchers examined stars that are close enough to Earth that telescopes set to begin operating in the next decade or two – including the Habitable Worlds Observatory in space and Extremely Large Telescopes on the ground – could take images of planets in the stars’ so-called habitable zones. This term defines orbits where the planets could have liquid water on their surfaces.

There are several factors influencing what could make a planet suitable for life as we know it. One of those factors is the amount of harmful X-rays and ultraviolet light they receive, which can damage or even strip away the planet’s atmosphere.

Based on X-ray observations of some of these stars using data from Chandra and XMM-Newton, the research team examined which stars could have hospitable conditions on orbiting planets for life to form and prosper. They studied how bright the stars are in X-rays, how energetic the X-rays are, and how much and how quickly they change in X-ray output, for example, due to flares. Brighter and more energetic X-rays can cause more damage to the atmospheres of orbiting planets.

The researchers used almost 10 days of Chandra observations and about 26 days of XMM observations, available in archives, to examine the X-ray behavior of 57 nearby stars, some of them with known planets. Most of these are giant planets like Jupiter, Saturn or Neptune, while only a handful of planets or planet candidates could be less than about twice as massive as Earth.

These results were presented at the 244th meeting of the American Astronomical Society meeting in Madison, Wisconsin, by Breanna Binder (California State Polytechnic University in Pomona).

NASA Announces New System to Aid Disaster Response

In early May, widespread flooding and landslides occurred in the Brazilian state of Rio Grande do Sul, leaving thousands of people without food, water, or electricity. In the following days, NASA teams provided data and imagery to help on-the-ground responders understand the disaster’s impacts and deploy aid.

Building on this response and similar successes, on June 13, NASA announced a new system to support disaster response organizations in the U.S. and around the world.

“When disasters strike, NASA is here to help – at home and around the world,” said NASA Administrator Bill Nelson. “As challenges from extreme weather grow, so too does the value of NASA’s efforts to provide critical Earth observing data to disaster-response teams on the frontlines. We’ve done so for years. Now, through this system, we expand our capability to help power our U.S. government partners, international partners, and relief organizations across the globe as they take on disasters – and save lives.”

The team behind NASA’s Disaster Response Coordination System gathers science, technology, data, and expertise from across the agency and provides it to emergency managers. The new system will be able to provide up-to-date information on fires, earthquakes, landslides, floods, tornadoes, hurricanes, and other extreme events.

“The risk from climate-related hazards is increasing, making more people vulnerable to extreme events,” said Karen St. Germain, director of NASA’s Earth Science Division. “This is particularly true for the 10% of the global population living in low-lying coastal regions who are vulnerable to storm surges, waves and tsunamis, and rapid erosion. NASA’s disaster system is designed to deliver trusted, actionable Earth science in ways and means that can be used immediately, to enable effective response to disasters and ultimately help save lives.”

Agencies working with NASA include the Federal Emergency Management Agency, the National Oceanic and Atmospheric Administration (NOAA), the U.S. Geological Survey, and the U.S. Agency for International Development – as well as international organizations such as World Central Kitchen.

“With this deliberate and structured approach, we can be even more effective in putting Earth science into action,” said Josh Barnes, at NASA’s Langley Research Center. Barnes manages the Disaster Response Coordination System.

NASA Administrator Bill Nelson delivers remarks June 13 during an event launching a new Disaster Response Coordination System that will provide communities and organizations around the world with access to science and data to aid disaster response.

NASA Disasters Team Aiding Brazil

When the floods and landslides ravaged parts of Brazil in May, officials from the U.S. Southern Command – working with the U.S. Space Force and Air Force, and regional partners – reached out to NASA for Earth-observing data.

NASA’s response included maps of potential power outages from the Black Marble project at NASA’s Goddard Space Flight Center. Disaster response coordinators at NASA Goddard also reviewed high-resolution optical data – from the Commercial Smallsat Data Acquisition Program – to map more than 4,000 landslides.

Response coordinators from NASA’s Jet Propulsion Laboratory and the California Institute of Technology produced flood extent maps using data from the NASA and U.S. Geological Survey Landsat mission and from ESA’s (the European Space Agency) Copernicus Sentinel-2 satellite. Response coordinators at NASA’s Johnson Space Center also provided photographs of the flooding taken by astronauts aboard the International Space Station.

Building on Previous Work

The Brazil event is just one of hundreds of responses NASA has supported over the past decade. The team aids decision-making for a wide range of natural hazards and disasters, from hurricanes and earthquakes to tsunamis and oil spills

“NASA’s Disasters Program advances science for disaster resilience and develops accessible resources to help communities around the world make informed decisions for disaster planning,” said Shanna McClain, manager of NASA’s Disasters Program. “The new Disaster Response Coordination System significantly expands our efforts to bring the power of Earth science when responding to disasters.”

      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.

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. NASA, ESA, CSA, STScI, SARAO, Samuel Crowe (UVA), John Bally (CU), Ruben Fedriani (IAA-CSIC), Ian Heywood (Oxford) Using Infrared to Reveal Forming Stars
      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.

      This NASA/ESA Hubble Space Telescope Picture of the Week features a sparkling spiral galaxy paired with a prominent star, both in the constellation Virgo. While the galaxy and the star appear to be close to one another, even overlapping, they’re actually a great distance apart.ESA/Hubble & NASA, S. J. Smartt, C. Kilpatrick This NASA/ESA Hubble Space Telescope image features a sparkling spiral galaxy paired with a prominent star, both in the constellation Virgo. While the galaxy and the star appear to be close to one another, even overlapping, they’re actually a great distance apart. The star, marked with four long diffraction spikes, is in our own galaxy. It’s just 7,109 light-years away from Earth. The galaxy, named NGC 4900, lies about 45 million light-years from Earth.
      This image combines data from two of Hubble’s instruments: the Advanced Camera for Surveys, installed in 2002 and still in operation today, and the older Wide Field and Planetary Camera 2, which was in use from 1993 to 2009. The data used here were taken more than 20 years apart for two different observing programs — a real testament to Hubble’s long scientific lifetime!
      Both programs aimed to understand the demise of massive stars. In one, researchers studied the sites of past supernovae, aiming to estimate the masses of the stars that exploded and investigate how supernovae interact with their surroundings. They selected NGC 4900 for the study because it hosted a supernova named SN 1999br.
      In the other program, researchers laid the groundwork for studying future supernovae by collecting images of more than 150 nearby galaxies. When researchers detect a supernova in one of these galaxies, they can refer to these images, examining the star at the location of the supernova. Identifying a supernova progenitor star in pre-explosion images gives valuable information about how, when, and why supernovae occur.
