Driving rapid innovation in the American space industry, NASA has awarded Katalyst Space Technologies of Flagstaff, Arizona, a contract to raise a spacecraft's orbit. Katalyst's robotic servicing spacecraft will rendezvous with NASA's Neil Gehrels Swift Observatory and raise it to a higher altitude, demonstrating a key capability for the future of space exploration and extending the Swift mission's science lifetime.
NASA's Swift launched in 2004 to explore the universe's most powerful explosions, called gamma-ray bursts. The spacecraft's low Earth orbit has been decaying gradually, which happens to satellites over time. However, because of recent increases in the Sun's activity, Swift is experiencing more atmospheric drag than anticipated, speeding up its orbital decay. While NASA could have allowed the observatory to reenter Earth's atmosphere, as many missions do at the end of their lifetimes, Swift's lowering orbit presents an opportunity to advance American spacecraft servicing technology.
"This industry collaboration to boost Swift's orbit is just one of many ways NASA works for the nation every day," said Nicky Fox, associate administrator, Science Mission Directorate, NASA Headquarters in Washington. "By moving quickly to pursue innovative commercial solutions, we're further developing the space industry and strengthening American space leadership. This daring mission also will demonstrate our ability to go from concept to implementation in less than a year - a rapid-response capability important for our future in space as we send humans back to the Moon under the Artemis campaign, to Mars, and beyond."
The orbit boost is targeted for spring 2026, though NASA will continue to monitor any changes in solar activity that may impact this target timeframe. A successful Swift boost would be the first time a commercial robotic spacecraft captures a government satellite that is uncrewed, or not originally designed to be serviced in space.
"Given how quickly Swift's orbit is decaying, we are in a race against the clock, but by leveraging commercial technologies that are already in development, we are meeting this challenge head-on," said Shawn Domagal-Goldman, acting director, Astrophysics Division, NASA Headquarters. "This is a forward-leaning, risk-tolerant approach for NASA. But attempting an orbit boost is both more affordable than replacing Swift's capabilities with a new mission, and beneficial to the nation - expanding the use of satellite servicing to a new and broader class of spacecraft."
