NASA Calls Off the Rescue of the Swift Space Telescope
Just months ago, engineers at Katalyst Space Technologies were holding their breath as their refrigerator-sized spacecraft, Link, headed towards NASA’s aging Swift Observatory, hoping to grab it and push it to safety. Now, that rescue mission is officially over.
On , NASA and Katalyst confirmed what many had feared: the undefined, a gamma-ray burst hunter that has circled Earth since 2004, will be allowed to fall from orbit and burn up in the atmosphere later this year. The decision came after Link suffered a critical malfunction that left it uncontrollably spinning in space, unable to complete its high-stakes rendezvous.
The story began in 2025, when NASA realized Swift was in great danger. The Sun’s 11-year activity cycle peaked more intensely than expected, warming Earth’s upper atmosphere and creating drag that pulled Swift downward at an accelerating rate. Without intervention, the telescope would soon be lost.
NASA moved quickly. It awarded aundefined contract to undefined, a small Arizona-based startup, tasking them with building a rescue spacecraft in just nine months. The resulting spacecraft, Link, launched on July 3, 2026, on a mission that NASA officials and Ghonhee Lee, CEO of Katalyst Space described as “high-risk, high-reward.”
For a few weeks, Link performed perfectly, but on July 25, the spacecraft suddenly lost contact with mission controllers. When communication resumed a day later, Link tumbled as it spun once every 40 seconds. Engineers later determined that two of Link’s three reaction wheels, critical for precise pointing, had failed, and its gas thrusters were performing inconsistently.
“Shutting down the reaction wheels in an uncontrolled manner—you’re essentially pulling the plug out from them,” said Ghonhee Lee, Katalyst’s CEO, in a undefined. “That’s not how they’re designed to operate.”
While Katalyst engineers managed to slow the tumble using the spacecraft’s electric propulsion system, they could not restore the precision needed to safely grab Swift. On August 19, the decision was made to call off the rescue.
“This is not the outcome we were working toward, but it does not change why this mission was worth attempting,”said in a statement.
Swift, currently orbiting at around 200 miles above Earth and dropping about 1.5 miles per week, will continue its descent. Once it reaches roughly 185 miles, atmospheric drag will pull it down rapidly, and the telescope will break apart upon reentry.
While the rescue mission has failed, Katalyst will continue to operate Link near Swift, gathering valuable data for future satellite servicing missions. The lessons learned from this attempt may one day help to save another spacecraft from a similar situation.
