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.

Hubble Pinpoints Young Stars in Spiral Galaxy
This NASA/ESA Hubble Space Telescope image features the spiral galaxy NGC 1317. ESA/Hubble & NASA, J. Lee and the PHANGS-HST Team In this image, the NASA/ESA Hubble Space Telescope peers into the spiral galaxy NGC 1317 in the constellation Fornax, located more than 50 million light-years from Earth. Visible in this galaxy image is a bright blue ring that hosts hot, young stars. NGC 1317 is one of a pair, but its rowdy larger neighbor, NGC 1316, lies outside Hubble’s field of view. Despite the absence of its neighboring galaxy, this image finds NGC 1317 accompanied by two objects from very different parts of the universe. The bright point ringed with a crisscross pattern is a star from our own galaxy surrounded by diffraction spikes, whereas the redder elongated smudge is a distant galaxy lying far beyond NGC 1317.
The data presented in this image are from a vast observing campaign of hundreds of observations from Hubble’s Wide Field Camera 3 and Advanced Camera for Surveys. Combined with data from the ALMA array in the Atacama Desert, these observations help astronomers chart the connections between vast clouds of cold gas and the fiercely hot, young stars that form within them. ALMA’s unparalleled sensitivity at long wavelengths identified vast reservoirs of cold gas throughout the local universe, and Hubble’s sharp vision pinpointed clusters of young stars, as well as measuring their ages and masses.
Often the most exciting astronomical discoveries require this kind of telescope teamwork, with cutting-edge facilities working together to provide astronomers with information across the electromagnetic spectrum. The same applies to Hubble’s observations that laid the groundwork for the NASA/ESA/CSA James Webb Space Telescope’s scientific observations.

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).

A first-generation college graduate, Nilufar Ramji was blazing trails long before arriving at NASA. With her multifaceted expertise, she is helping shape the messaging behind humanity’s return to the Moon, Mars, and beyond.
Ramji is currently on detail as the co-executive producer for NASA’s live broadcasts, ensuring the agency’s missions and discoveries are clearly and effectively communicated to the public. Through her work, she expands understanding of what space exploration means for all—and why it matters.
Official portrait of Nilufar Ramji. NASA/Josh Valcarcel Before stepping into her acting role, Ramji served as the lead public affairs officer for Moon to Mars activities at NASA’s Johnson Space Center in Houston. She spearheaded communication strategies for the Commercial Lunar Payload Services initiative, which works with private companies to deliver science and technology payloads to the lunar surface. She has also provided live commentary for International Space Station operations to learn and prepare for Artemis missions.
Ramji played a pivotal role in communicating NASA’s involvement in two major lunar missions in 2025 including Firefly Aerospace’s Blue Ghost Mission 1 which successfully delivered 10 NASA payloads to the Moon’s Mare Crisium on March 2. Ramji served as the live mission commentator, helping audiences around the world follow the historic moment—from lunar orbit insertion to touchdown. She also led communications for Intuitive Machines’ IM-2 mission, which landed near the Moon’s South Pole on March 6, marking the southernmost lunar landing ever achieved.
Nilufar Ramji, left, and Brigette Oakes, vice president of engineering at Firefly Aerospace, in the company’s mission operations center in Cedar Park, Texas, during the Blue Ghost Mission 1 lunar landing. NASA/Helen Arase Vargas Early in her NASA career, she led agencywide STEM communications, shaping how NASA connects with students and educators. As a lead strategist, she developed messaging that made science and technology more accessible to younger audiences—helping inspire the Artemis Generation.
“Being one of the storytellers behind humanity’s return to the Moon is something I take pride in,” she said. “People don’t realize what exploring our solar system has done for us here on Earth. Going to the Moon and onto Mars will bring that message home.”
Nilufar Ramji, left, and Aliyah Craddock, digital media lead for NASA Science in the Science Mission Directorate, in the Astromaterials Research and Exploration Science laboratory at NASA’s Johnson Space Center in Houston. NASA Ramji communicates not just the science of space, but its greater significance. “How can we be thoughtful in our communications?” is a question that drives her approach. Whether guiding a live broadcast or developing messaging about lunar science, she is constantly evaluating, executing, and refining NASA’s voice.
She also understands the importance of commercial partnerships in expanding human presence in space. “It’s exciting to see how many different people and organizations come together to make this a reality,” she said. “By creating a larger space economy, we’re able to do things faster and cheaper and still accomplish the same goals to make sure we’re all successful.”
Nilufar Ramji presents a TedX Talk, “Storytelling from Space” in Sugar Land, Texas. In Aug. 2023, Ramji delivered a TEDx Talk, “Storytelling from Space” in Sugar Land, Texas, where she emphasized the power of narrative to inspire and unite humanity in the quest to explore the universe. Drawing from her NASA experience, she illustrated how communication bridges the gap between complex science and public engagement.
She credits her mentors and colleagues for supporting her growth. “I have great mentors and people I can lean on if I need help,” she said. “It’s something I didn’t realize I had until I came to NASA.”
Ramji believes stepping outside your comfort zone is essential. “Discomfort brings new learning, understanding, and opportunities, so I like being uncomfortable at times,” she said. “I’m open and receptive to feedback. Constructive criticism has helped me grow and evolve—and better understand NASA’s mission.”
For her, balance means creating intentional space for reflection, growth, and meaningful connection.
Nilufar Ramji gives remarks during Johnson’s building naming ceremony of the “Dorothy Vaughan Center in Honor of the Women of Apollo” on July 19, 2024. NASA/Robert Markowitz Before joining NASA, Ramji had already built an international career rooted in service. She worked at the Aga Khan Foundation in Canada, a nonprofit organization focused on addressing challenges in underdeveloped communities through education and healthcare.
She led visitor programs, workshops and more than 250 events—often for diplomats and global leaders—to promote “quiet diplomacy” and dialogue.
“Transparency, quality, fairness and diversity of perspective are all important to me,” she said. “People come from different experiences that broaden our understanding.”
Ramji later moved to East Africa as the foundation’s sole communications representative across Kenya, Tanzania, and Uganda. There, she trained more than 300 staff and built a communications strategy to help local teams share stories of impact—both successes and challenges—with honesty and empathy.
Her work left a lasting mark on the communities she served and underscored the power of communication to drive positive change.
Nilufar Ramji captures the story of a sesame farmer in Mtwara, Tanzania, whose livelihood improved through a rural development program initiated by the Aga Khan Foundation. In 2013, Ramji moved to the United States and started over, rebuilding her network and career. She worked for the Aga Khan Council for USA in Houston, leading a volunteer recruitment program that connected thousands of people with roles suited to their skills.
She later applied for a contractor position—not knowing it was with NASA. “I never thought my skills or expertise would be valued at a place like NASA,” she said. But in 2018, she accepted a role as a public relations specialist supporting International Space Station outreach. She has been shaping the agency’s storytelling ever since.
Ramji’s journey represents NASA’s commitment to pushing boundaries and expanding humanity’s knowledge of the universe. With collaboration, transparency, and vision, she is helping bring the next frontier of space exploration to life.
