Swift Boost Mission
After 21 years, the orbit of NASA’s Neil Gehrels Swift Observatory has entered a phase of rapid decay. While NASA could have allowed the observatory to re-enter Earth’s atmosphere, as many missions do at the end of their lifetimes, the situation presented an opportunity to develop a way to advance American spacecraft servicing technology and raise Swift’s orbit.
NASA has contracted Katalyst Space Technologies of Flagstaff, Arizona, to mount a robotic servicing mission, launching a spacecraft that will rendezvous with Swift and boost it to a higher altitude. The project will demonstrate a key capability for the future of space exploration while also extending Swift’s scientific life. The boost mission is expected to launch no earlier than June 2026.
Swift launched in 2004 to study the universe’s most powerful explosions, called gamma-ray bursts, as well as other cosmic objects and events. Swift's altitude gradually decreased since launch due to interaction with the Earth's atmosphere. Recent unanticipated increases in solar activity have accelerated this decay, as they heat the Earth's atmosphere, causing it to puff outward, increasing drag. Swift carries no thrusters to counteract this effect.
Katalyst Wraps Testing at NASA Goddard for Swift Boost Mission
A daring mission to lift NASA’s sinking Neil Gehrels Swift Observatory is now one step closer to launch this June. On May 4, Katalyst Space Technologies completed environmental tests of its LINK robotic servicing spacecraft at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. LINK will meet up with Swift and attempt to raise its orbit.
