Overview
- The Neil Gehrels Swift Observatory is in an uncontrolled descent and U.S. and independent trackers are narrowing the reentry window to roughly Nov. 4–6 as they update predictions over the final orbits.
- NASA and contractor Katalyst concluded the July‑launched LINK servicing craft could not capture or boost Swift after persistent attitude and control problems, ending the last rescue option.
- Most of the roughly 1.5–1.6 tonne spacecraft is expected to burn up on reentry, but experts say heavy items such as reaction wheels, mirror components and tungsten parts could survive and fall between 20.6°N and 20.6°S latitude.
- NASA rates the chance of a person being injured by surviving debris as very low—about 1 in 2,100—and the equatorial debris band covers mostly ocean though parts of Africa, Australia, India, Southeast Asia and the Americas are inside the zone.
- Swift’s loss ends a nearly 22‑year run that produced roughly 2,000 gamma‑ray burst detections and about 7,000 papers, and it highlights technical limits in rapid on‑orbit servicing, gaps in debris mitigation, and the need for better tracking and end‑of‑life design.
