NASA’s Swift observatory is nearing re-entry after a commercial orbit-raising effort failed, with a U.S. tracker projecting a Nov. 4 return that would close the telescope’s 21-year mission.
The Center for Orbital and Reentry Debris Studies (CORDS), part of The Aerospace Corporation, lists a return time of 09:30 UTC on Nov. 4, 2026, with a 26-hour uncertainty on either side. The estimate uses orbital data dated Oct. 30. NASA’s Oct. 23 update gave a broader window, saying re-entry could occur within the coming weeks.
The Associated Press reported Oct. 31 that the U.S. Space Force expected Swift to return around Friday, without specifying a calendar date. The AP also reported that tungsten and mirror components might survive re-entry, with any surviving debris most likely to land in the ocean.
Swift was at 171 miles (275 kilometers) on Oct. 20 when NASA said atmospheric drag had stopped it from holding a stable observing position. The observatory entered safe mode, and its operations team sent the command to end science work. NASA linked the faster orbital decline in part to increased solar activity. EconoTimes previously covered Swift’s shutdown and NASA’s re-entry outlook.
The attempted boost relied on LINK, a servicing spacecraft built by Katalyst Space Technologies. NASA awarded the company $30 million in September 2025, with roughly a year for it to prepare the craft for launch. In August, NASA and Katalyst said an attitude-control problem meant LINK would not capture or boost Swift. NASA later reported intermittent communication losses and orientation problems during demonstrations. LINK passed within 7.5 to 9 miles (12 to 15 kilometers) of Swift before re-entering Sept. 25.
Swift launched Nov. 20, 2004, with a two-year primary mission, then remained active for more than a decade past its original design span. NASA says its observations included more than 2,000 gamma-ray bursts and more than 1,400 supernova explosions, and contributed to about 7,000 published papers. The agency is assessing how its existing telescopes, commercial spacecraft and future missions could support rapid follow-up observations of cosmic events.
