NASA calls off rescue mission for Swift space telescope after spacecraft control failures
Katalyst Space Technologies' Link probe will no longer boost the aging observatory, leaving it on track to burn up in Earth's atmosphere later this year.
The short version
- NASA and Katalyst Space Technologies canceled the planned orbital boost of the Swift observatory after the Link rescue spacecraft suffered ongoing attitude control problems.
- Without a propulsion system of its own, the 20-year-old gamma-ray telescope will continue its atmospheric descent and is projected to reenter Earth's atmosphere late this year.
- The mission will pivot to a proximity and rendezvous demonstration near Swift to collect operational data for future in-orbit satellite servicing attempts.
Key facts
- NASA and contractor Katalyst Space Technologies announced the cancellation of the mission to capture and raise the Swift observatory's orbit due to persistent control and pointing issues on the Link spacecraft.[Wired · Associated Press · Slashdot]
- NASA paid Katalyst $30 million to attempt to raise Swift's orbit after intense solar activity expanded Earth's upper atmosphere and accelerated the telescope's descent.[Wired · Associated Press]
- The Link spacecraft launched on July 3, 2026, but entered an uncontrolled spin weeks later, causing delays and positioning failures that prevented a capture attempt.[Wired · Associated Press · Slashdot]
- Swift, which has operated since 2004 tracking gamma-ray bursts, is expected to reenter the atmosphere no earlier than October and largely burn up before the end of 2026.[Wired · Associated Press]
- Katalyst will continue operating Link to perform rendezvous and proximity operations near Swift as a technology demonstration for future satellite servicing.[Wired · Associated Press · Slashdot]
What remains uncertain
- The exact timing and geographic location of Swift's atmospheric reentry remain unknown beyond NASA estimates pointing to late 2026, no earlier than October.[Wired · Associated Press]
- It is unclear how the failure will affect potential future orbit-boosting efforts for other declining satellites, such as the Hubble Space Telescope.[Associated Press]
