NASA Explores Industry Possibilities to Raise Swift Mission’s Orbit

NASA News - Mon, 08/11/2025 - 3:55pm

To drive the development of key space-based capabilities for the United States, NASA is exploring an opportunity to demonstrate technology to raise a spacecraft’s orbit to a higher altitude. Two American companies – Cambrian Works of Reston, Virginia, and Katalyst Space Technologies of Flagstaff, Arizona – will develop concept design studies for a possible orbit boost for the agency’s Neil Gehrels Swift Observatory.

Since its launch in 2004, NASA’s Swift mission has led the agency’s fleet of space telescopes in investigating changes in the high-energy universe. The spacecraft’s low Earth orbit has been decaying gradually, which happens to most satellites over time. Because of recent increases in the Sun’s activity, however, Swift is experiencing additional atmospheric drag, speeding up its orbital decay. This lowering orbit presents an opportunity for NASA to advance a U.S. industry capability, while potentially extending the science lifetime of the Swift mission. The concept studies will help determine whether extending Swift’s critical scientific capabilities would be more cost-effective than replacing those capabilities with a new observatory.

“NASA Science is committed to leveraging commercial technologies to find innovative, cost-effective ways to open new capabilities for the future of the American space sector,” said Nicky Fox, associate administrator, Science Mission Directorate, NASA Headquarters in Washington. “To maintain Swift’s role in our portfolio, NASA Science is uniquely positioned to conduct a rare in-space technology demonstration to raise the satellite’s orbit and solidify American leadership in spacecraft servicing.”

The concept studies are being developed under Phase III awards through NASA’s Small Business Innovation Research (SBIR) Program, managed by the agency’s Space Technology Mission Directorate, to American small businesses from a pool of existing participants. This approach allows NASA to rapidly explore affordable possibilities to boost Swift on a shorter development timeline than would otherwise be possible, given the rapid rate at which Swift’s orbit is decaying.

At this time NASA does not have plans for an orbit boost mission and could still allow the spacecraft to reenter Earth’s atmosphere, as many satellites do at the end of their lifetimes. NASA is studying a potential Swift boost to support innovation in the American space industry, while gaining a better understanding of the available options, the technical feasibility, and the risks involved.

NASA will also work with Starfish Space of Seattle, Washington, to analyze the potential of performing a Swift boost using an asset under development on an existing Phase III SBIR award. Starfish is currently developing the Small Spacecraft Propulsion and Inspection Capability (SSPICY) demonstration for NASA, with the primary objective of inspecting multiple U.S.-owned defunct satellites in low Earth orbit.

“Our SBIR portfolio exists for circumstances like this – where investments in America’s space industry provide NASA and our partners an opportunity to develop mutually beneficial capabilities,” said Clayton Turner, associate administrator, Space Technology Mission Directorate, NASA Headquarters. “Whether we choose to implement the technologies in this circumstance, understanding how to boost a spacecraft’s orbit could prove valuable for future applications.”

Swift was designed to observe gamma-ray bursts, the universe’s most powerful explosions, and provide information for other NASA and partner telescopes to follow up on these events. Its fast and flexible observations have been instrumental in advancing how scientists study transient events to understand how the universe works. For more than two decades, Swift has led NASA’s missions in providing new insights on these events, together broadening our understanding of everything from exploding stars, stellar flares, and eruptions in active galaxies, to comets and asteroids in our own solar system and high-energy lightning events on Earth.

“Over its extremely productive lifetime, Swift has been a key player in NASA’s network of space telescopes – directing our fleet to ensure we keep a watchful eye on changes in the universe, both far off and close to home,” said Shawn Domagal-Goldman, acting director, Astrophysics Division, NASA Headquarters. “Now, this long-lived science mission is presenting us with a new opportunity: partnering with U.S. industry to rapidly explore efficient, state-of-the-art solutions that could extend Swift’s transformative work and advance private spacecraft servicing.”

Cambrian and Katalyst have each been awarded $150,000 under Phase III SBIR contracts for concept design studies. The NASA SBIR program is part of America’s Seed Fund, the nation’s largest source of early-stage, non-dilutive funding for innovative technologies. Through this program, entrepreneurs, startups, and small businesses with less than 500 employees can receive funding and non-monetary support to build, mature, and commercialize their technologies, advancing NASA missions and helping solve important problems facing our country.

NASA’s Goddard Space Flight Center in Greenbelt, Maryland, manages the Swift mission in collaboration with Penn State, the Los Alamos National Laboratory in New Mexico, and Northrop Grumman Space Systems in Dulles, Virginia. Other partners include the UK Space Agency, University of Leicester and Mullard Space Science Laboratory in the United Kingdom, Brera Observatory in Italy, and the Italian Space Agency.

Space Station Cell Studies

3 Min Read Space Station Cell Studies Cells grown aboard the International Space Station. Credits: University of Connecticut Science in Space August 2025

Cells are the basic building blocks of all living things, from single-celled bacteria to plants and animals containing vast numbers of them. Cells have adapted for a wide variety of settings and functions. Nerve cells in humans and animals, for example, have long, thin extensions that rapidly transmit signals, while rigid, blocky cells support the structure of plants.

Cell biology is the study of cell structure, function, and behavior. For humans, scientists in this field explore the mechanisms of diseases from bone loss to cancer and work on developing treatments.

Cell-based experiments on The International Space Station help identify how spaceflight affects people and other living systems, with applications for future space exploration and life on Earth.

JAXA astronaut Satoshi Furukawa prepares to examine cells for Cell Gravisensing in the JAXA Confocal Microscope (COSMIC).NASA

Recent experiments have revealed that individual animal cells react to the effects of gravity, but how they do so is largely unknown. Cell Gravisensing, an investigation from JAXA (Japan Aerospace Exploration Agency), examines the molecular mechanism behind the ability of cells to sense gravity. Results could support development of drugs to treat muscle atrophy and osteoporosis in space and on Earth.

Cardiovascular cells Microscopic view of cells from the lining of blood vessels cultured for the STaARS BioScience-3 experiment. University of Florida

In microgravity, some astronauts experience changes in their cardiovascular system, including reduced blood volume and diminished cardiac output. An earlier investigation, STaARS Bioscience-3, examined the mechanisms behind these changes at the cellular and genetic level. The research revealed that, after only three days of spaceflight, there were changes in the expression of more than 11,000 genes in blood vessel cells that could alter their functions. The results laid the groundwork for additional research into cell response to spaceflight that could help protect the health of crew members on future missions and people with cardiovascular diseases on Earth.

Neural cells

STaARS BioScience-4 examined microgravity’s effects on neural stem cells that give rise to central nervous system cells. Researchers found changes in production and consumption of energy and increased breakdown of cellular components in these cells, responses that likely enhance adaptation to microgravity. The finding also highlights the importance of providing astronauts with sufficient energy for cognitive and physiological function on future missions.

Goldfish scales have many of the same proteins, minerals, and cell types as the bones of mammals. The JAXA Fish Scales investigation analyzed goldfish scales exposed to three times Earth’s gravity, simulated microgravity, and microgravity on orbit. Researchers determined that goldfish scales can be used as a model to help them understand how human bones respond to spaceflight.

Mouse cells

Research with model organisms like rodents has relevance to humans in space and makes significant contributions to understanding human aging, disease, and the effects of microgravity on biological and physical processes. JAXA’s Stem Cells studied how spaceflight affected the DNA and chromosomes of embryonic mouse stem cells, and their ability to develop into adult mice after return to Earth.

Researchers analyzed unaltered cells and cells given a mutation to increase responsiveness to radiation. They found no chromosomal differences between the unaltered space-flown cells and ground controls, but the mutated cells had more DNA abnormalities. The work could enhance the understanding of radiation effects on human cancer and improve risk assessment for long-duration missions to the Moon and Mars.

Another study used tissue samples from RR-1, which are available through NASA’s GeneLab open data repository. Analysis showed that the heart can adapt to the stress of spaceflight in just 30 days. The researchers observed genetic changes suggesting that this adaptation may facilitate survival in space and could have applications in treating heart disease in space and on Earth.
