A Space Telescope Is Falling to Earth. NASA Plans a Mission to Rescue It
A commercial robot will attempt the first capture of a government satellite never designed for servicing, using robotic arms to extend Swift’s life.
NASA is preparing a first-of-its-kind mission to rescue the aging Neil Gehrels Swift Observatory, which is losing altitude and could reenter Earth's atmosphere due to increased atmospheric drag from solar activity.
A spacecraft called Link, developed by Katalyst Space Technologies, will attempt to rendezvous and dock with the telescope—even though Swift was never designed for docking—and raise it into a higher orbit.
Arizona-Based startup Katalyst Space Technologies built the 935-pound rescue craft in just 250 days, equipping it with reaction-control thrusters, robotic arms and rendezvous sensors to safely boost the observatory without damage.
If successful, the mission could extend Swift's operational life by at least five years and demonstrate new capabilities for servicing satellites and telescopes already in orbit.
The project was developed on a rapid timeline and relatively modest budget, making it a major test of commercial space-servicing technology and a potential model for future rescue missions.
