Preparations for Next Moonwalk Simulations Underway (and Underwater)
Will the Sun ever burn out?
Well, the Sun, just like the stars we see at night, is a star. It’s a giant ball of super hot hydrogen.
Gravity squeezes it in and it creates energy, which is what makes the Sun shine. Eventually, it will use up all of that hydrogen. But in the process, it’s creating helium. So it will then use the helium. And it will continue to use larger and larger elements until it can’t do this anymore.
And when that happens, it will start to expand into a red giant about the size of the inner planets. Then it will shrink back down into a very strange star called a white dwarf — super hot, but not very bright and about the size of the Earth.
But our Sun has a pretty long lifetime. It’s halfway through its 10-billion-year lifetime.
So the Sun will never really burn out, but it will change and be a very, very different dim kind of star when it reaches the end of its normal life.

Eclipses, Auroras, and the Spark of Becoming: NASA Inspires Future Scientists
In the heart of Alaska’s winter, where the night sky stretches endlessly and the aurora dances across the sky in a display of ethereal beauty, nine undergraduate students from across the United States were about to embark on a transformative journey. These students had been active ‘NASA Partner Eclipse Ambassadors’ in their home communities, nine of more than 700 volunteers who shared the science and awe of the 2024 eclipse with hundreds of thousands of people across the country as part of the NASA Science Activation program’s Eclipse Ambassadors project. Now, these nine were chosen to participate in a once-in a lifetime experience as a part of the “Eclipses to Aurora” Winter Field School at the University of Alaska Fairbanks. Organized by the Astronomical Society of the Pacific and NASA’s Aurorasaurus Citizen Science project, supported by NASA, this program offered more than just lectures—it was an immersive experience into the wonders of heliophysics and the profound connections between the Sun and Earth.
From January 4 to 11, 2025, the students explored the science behind the aurora through seminars on solar and space physics, hands-on experiments, and tours of cutting-edge research facilities like the Poker Flat Research Range. They also gained invaluable insight from Athabaskan elders, who shared local stories and star knowledge passed down through generations. As Feras recalled, “We attended multiple panels on solar and space physics, spoke to local elders on their connection to the auroras, and visited the Poker Flat Research Range to observe the stunning northern lights.”
For many students, witnessing the aurora was not only a scientific milestone, but a deeply personal and emotional experience. One participant, Andrea, described it vividly: “I looked to the darkest horizon I could find to see my only constant dream fulfilled before my eyes, so slowly dancing and bending to cradle the stars. All I could do, with my hands frozen and tears falling, I began to dream again with my eyes wide open.” Another student, Kalid, reflected on the shared human moment: “Standing there under the vast Alaskan sky… we were all just people, looking up, waiting for something magical. The auroras didn’t care about our majors or our knowledge—they brought us together under the same sky.”
These moments of wonder were mirrored by a deeper sense of purpose and transformation. “Over the course of the week, I had the incredible opportunity to explore auroras through lectures on solar physics, planetary auroras, and Indigenous star knowledge… and to reflect on these experiences through essays and presentations,” said Sophia. The Winter Field School was more than an academic endeavor—it was a celebration of science, culture, and shared human experience. It fostered not only understanding but unity and awe, reminding everyone involved of the profound interconnectedness of our universe.
The impact of the program continues to resonate. For many students, that one aurora-lit week in Alaska became a turning point in the focus of their careers. Sophia has since been accepted into graduate school to pursue heliophysics. Vishvi, inspired by the intersection of science and society, will begin a program in medical physics at the University of Pennsylvania this fall. And Christy, moved by her time at the epicenter of aurora research, has applied to the Ph.D. program in Space Physics at the University of Alaska Fairbanks—the very institution that helped spark her journey. Their stories are powerful proof that the Winter Field School didn’t just teach—it awakened purpose, lit new paths, and left footprints on futures still unfolding.
Eclipse Ambassadors is supported by NASA under cooperative agreement award number 80NSS22M0007 and is part of NASA’s Science Activation Portfolio.

Credit: NASA NASA has selected Rocket Lab USA Inc. of Long Beach, California, to launch the agency’s Aspera mission, a SmallSat to study galaxy formation and evolution, providing new insights into how the universe works.
The selection is part of NASA’s Venture-Class Acquisition of Dedicated and Rideshare (VADR) launch services contract. This contract allows the agency to make fixed-price indefinite-delivery/indefinite-quantity launch service task order awards during VADR’s five-year ordering period, with a maximum total contract value of $300 million.
Through the observation of ultraviolet light, Aspera will examine hot gas in the space between galaxies, called the intergalactic medium. The mission will study the inflow and outflow of gas from galaxies, a process thought to contribute to star formation.
Aspera is part of NASA’s Pioneers Program in the Astrophysics Division at NASA Headquarters in Washington, which funds compelling astrophysics science at a lower cost using small hardware and modest payloads. The principal investigator for Aspera is Carlos Vargas at the University of Arizona in Tucson. NASA’s Launch Services Program, based at the agency’s Kennedy Space Center in Florida, manages the VADR contract.

The Ax-4 launch aboard a SpaceX Dragon spacecraft on the company’s Falcon 9 rocket is targeted no earlier than 9:11 a.m., Sunday, June 8, from NASA’s Kennedy Space Center in Florida.
During the mission aboard the space station, a four-person multi-national crew will complete about 60 research experiments developed for microgravity in collaboration with organizations across the globe.
Peggy Whitson, former NASA astronaut and director of human spaceflight at Axiom Space, will command the commercial mission, while ISRO astronaut Shubhanshu Shukla will serve as pilot. The two mission specialists are ESA project astronaut Sławosz Uznański-Wiśniewski of Poland and Tibor Kapu of Hungary.
The first private astronaut mission to the station, Axiom Mission 1, lifted off in April 2022 for a 17-day mission aboard the orbiting laboratory. The second private astronaut mission to the station, Axiom Mission 2, also was commanded by Whitson and launched in May 2023 for eight days in orbit. The most recent private astronaut mission, Axiom Mission 3, launched in January 2024; the crew spent 18 days docked to the space station.
The International Space Station is a springboard for developing a low Earth economy. NASA’s goal is to achieve a strong economy off the Earth where the agency can purchase services as one of many customers to meet its science and research objectives in microgravity. NASA’s commercial strategy for low Earth orbit provides the government with reliable and safe services at a lower cost, enabling the agency to focus on Artemis missions to the Moon in preparation for Mars while also continuing to use low Earth orbit as a training and proving ground for those deep space missions.

For the first time, researchers confirmed the presence of crystalline water ice in a dusty debris disk that orbits a Sun-like star, using NASA’s James Webb Space Telescope. The full artist’s concept illustration and full caption is shown below. Credits:
NASA, ESA, CSA, Ralf Crawford (STScI) Is frozen water scattered in systems around other stars? Astronomers have long expected it is, partially based on previous detections of its gaseous form, water vapor, and its presence in our own solar system.
Now there is definitive evidence: Researchers confirmed the presence of crystalline water ice in a dusty debris disk that orbits a Sun-like star 155 light-years away using detailed data known as spectra from NASA’s James Webb Space Telescope. (The term water ice specifies its makeup, since many other frozen molecules are also observed in space, such as carbon dioxide ice, or “dry ice.”) In 2008, data from NASA’s retired Spitzer Space Telescope hinted at the possibility of frozen water in this system.
“Webb unambiguously detected not just water ice, but crystalline water ice, which is also found in locations like Saturn’s rings and icy bodies in our solar system’s Kuiper Belt,” said Chen Xie, the lead author of the new paper and an assistant research scientist at Johns Hopkins University in Baltimore, Maryland.
All the frozen water Webb detected is paired with fine dust particles throughout the disk — like itsy-bitsy “dirty snowballs.” The results published Wednesday in the journal Nature.
Astronomers have been waiting for this definitive data for decades. “When I was a graduate student 25 years ago, my advisor told me there should be ice in debris disks, but prior to Webb, we didn’t have instruments sensitive enough to make these observations,” said Christine Chen, a co-author and associate astronomer at the Space Telescope Science Institute in Baltimore. “What’s most striking is that this data looks similar to the telescope’s other recent observations of Kuiper Belt objects in our own solar system.”
Water ice is a vital ingredient in disks around young stars — it heavily influences the formation of giant planets and may also be delivered by small bodies like comets and asteroids to fully formed rocky planets. Now that researchers have detected water ice with Webb, they have opened the door for all researchers to study how these processes play out in new ways in many other planetary systems.
Image: Debris Disk Around Star HD 181327 (Artist’s Concept)
For the first time, researchers confirmed the presence of crystalline water ice in a dusty debris disk that orbits a Sun-like star, using NASA’s James Webb Space Telescope. All the frozen water detected by Webb is paired with fine dust particles throughout the disk. The majority of the water ice observed is found where it’s coldest and farthest from the star. The closer to the star the researchers looked, the less water ice they found. NASA, ESA, CSA, Ralf Crawford (STScI) Rocks, Dust, Ice Rushing Around
The star, cataloged HD 181327, is significantly younger than our Sun. It’s estimated to be 23 million years old, compared to the Sun’s more mature 4.6 billion years. The star is slightly more massive than the Sun, and it’s hotter, which led to the formation of a slightly larger system around it.
Webb’s observations confirm a significant gap between the star and its debris disk — a wide area that is free of dust. Farther out, its debris disk is similar to our solar system’s Kuiper Belt, where dwarf planets, comets, and other bits of ice and rock are found (and sometimes collide with one another). Billions of years ago, our Kuiper Belt was likely similar to this star’s debris disk.
“HD 181327 is a very active system,” Chen said. “There are regular, ongoing collisions in its debris disk. When those icy bodies collide, they release tiny particles of dusty water ice that are perfectly sized for Webb to detect.”
Frozen Water — Almost Everywhere
Water ice isn’t spread evenly throughout this system. The majority is found where it’s coldest and farthest from the star. “The outer area of the debris disk consists of over 20% water ice,” Xie said.
The closer in the researchers looked, the less water ice they found. Toward the middle of the debris disk, Webb detected about 8% water ice. Here, it’s likely that frozen water particles are produced slightly faster than they are destroyed. In the area of the debris disk closest to the star, Webb detected almost none. It’s likely that the star’s ultraviolet light vaporizes the closest specks of water ice. It’s also possible that rocks known as planetesimals have “locked up” frozen water in their interiors, which Webb can’t detect.
This team and many more researchers will continue to search for — and study — water ice in debris disks and actively forming planetary systems throughout our Milky Way galaxy. “The presence of water ice helps facilitate planet formation,” Xie said. “Icy materials may also ultimately be ‘delivered’ to terrestrial planets that may form over a couple hundred million years in systems like this.”
The researchers observed HD 181327 with Webb’s NIRSpec (Near-Infrared Spectrograph), which is super-sensitive to extremely faint dust particles that can only be detected from space.
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).
