# NASA Ends Swift Observatory's Mission After a $30m Rescue Attempt Failed URL: https://edufabtech.com/news/nasa-swift-observatory-ends-mission-after-failed-rescue Section: News · Space Published: 2026-11-04 Publisher: EduFabTech (https://edufabtech.com) > NASA says its Neil Gehrels Swift Observatory took its last observation on 20 October 2026, ending nearly 22 years of work after a $30 million commercial rescue mission failed to raise its orbit. NASA says its Neil Gehrels Swift Observatory made its final observation on 20 October 2026, ending a science mission that outlasted its two-year design life by nearly two decades. The agency confirmed the end of the mission in an update published on 23 October 2026, after a commercial spacecraft sent to reboost Swift's decaying orbit lost control and could not complete the rescue, according to NASA Science. Swift launched on 20 November 2004 to study gamma-ray bursts — brief, intense flashes of high-energy radiation produced by exploding stars and merging compact objects. Over nearly 22 years it detected more than 2,000 gamma-ray bursts and observed more than 1,400 supernovae, and its data fed roughly 7,000 scientific papers, NASA Science reports. Its archive, about 12 terabytes, remains publicly accessible. S. Bradley Cenko of NASA's Goddard Space Flight Center has served as the mission's principal investigator; the mission was renamed in 2018 to honor its first principal investigator, Neil Gehrels. ![A four-stage timeline traces the rescue attempt from Swift's orbital decay through LINK's July launch, its reaction-wheel failure, to the rescue being abandoned by October.](https://edufabtech.com/uploads/2026/11/nasa-swift-observatory-ends-mission-after-failed-rescue-2.png) *A four-stage timeline traces the rescue attempt from Swift's orbital decay through LINK's July launch, its reaction-wheel failure, to the rescue being abandoned by October. — EduFabTech · Own work* The mission ended because Swift's orbit had decayed to less than 171 miles (275 kilometers) above Earth's surface, a height at which atmospheric drag made it impossible for the spacecraft's telescopes to hold steady on astronomical targets, according to NASA Science. The observatory is expected to re-enter the atmosphere within weeks of the October 2026 announcement. ## A commercial rescue that lost control NASA had tried to avoid this outcome. On 24 September 2025, the agency announced a $30 million Phase III award under its Small Business Innovation Research program to Katalyst Space Technologies, to build a robotic servicing spacecraft that would rendezvous with Swift and raise it to a higher orbit, according to a NASA news release. NASA described the plan as the first attempt by a commercial robotic spacecraft to capture a government satellite that was not originally designed for in-space servicing, and said the push was needed because recent increases in solar activity had intensified atmospheric drag on Swift's low Earth orbit, accelerating its decay faster than anticipated. Nicky Fox, associate administrator of NASA's Science Mission Directorate, said at the time, "By moving quickly to pursue innovative commercial solutions, we're further developing the space industry and strengthening American space leadership." Katalyst's servicing spacecraft, named LINK, launched on a Pegasus-XL rocket from Kwajalein Atoll in the Marshall Islands on 3 July 2026, according to Gunter's Space Page, which tracks spacecraft launch and mission data. By late July, LINK developed attitude-control problems: two of its three reaction wheels became inoperable and it lost some functionality in its cold-gas thruster system, sending the spacecraft into a multi-axis spin while its power and communications links kept working, the same source reports. Katalyst used xenon ion thrusters to slow the spin from 9 degrees per second to 1.47 degrees per second by 5 August 2026 and uploaded new flight software on 11 August, but by 19 August 2026 Katalyst and NASA concluded that LINK could not be stabilized enough to perform the planned capture and reboost, downgrading the mission to a limited demonstration of proximity operations only. ## What it means for researchers Swift's X-ray Telescope and Ultraviolet/Optical Telescope gave astronomers simultaneous, multiwavelength coverage of gamma-ray bursts. Swift itself typically took about a minute to detect a burst, locate it and swing its telescopes into position, and astronomers could command follow-up observations from the ground in as little as a few minutes, according to NASA Science. With Swift gone, NASA says it is exploring ways to use and augment its existing fleet of space telescopes to help fill that gap. Swift's roughly 12-terabyte public archive remains open, so the record of more than two decades of gamma-ray bursts and supernovae stays available for reanalysis even though the spacecraft itself is no longer collecting new data. ![A line chart plots the rescue craft LINK's spin rate dropping from 9°/s to 1.47°/s by early August, with a note that the reduction still wasn't enough for NASA to proceed with capture.](https://edufabtech.com/uploads/2026/11/nasa-swift-observatory-ends-mission-after-failed-rescue-3.png) *A line chart plots the rescue craft LINK's spin rate dropping from 9°/s to 1.47°/s by early August, with a note that the reduction still wasn't enough for NASA to proceed with capture. — EduFabTech · Own work* ## A test case for commercial servicing The Swift rescue attempt was also a test of whether commercial in-space servicing can extend the life of government satellites that were never built to be serviced. NASA announced Katalyst's award on 24 September 2025, and LINK launched on 3 July 2026; the reaction-wheel failures that doomed the capture attempt followed within weeks, by late July 2026, according to Gunter's Space Page. The outcome is a reminder that servicing missions carry their own failure modes, separate from the spacecraft they are sent to rescue. Swift's scientific mission is now formally over, but the data it already collected — on gamma-ray bursts, supernovae and other transient high-energy events — will continue to be mined by researchers through the mission's public archive, per NASA Science. ## Sources 1.
