Overview
- The Neil Gehrels Swift Observatory has lost attitude control and is forecast to reenter the atmosphere in the coming hours with the U.S. Space Force and NASA updating predictions, and agencies say the chance of harm to people is low.
- A commercial rescue by Katalyst Space Technologies was aborted after an orientation failure blamed on elevated solar activity, and the rescue vehicle itself reentered uncontrolled earlier this year.
- Models and military tracking place the likely reentry inside an equatorial band within about 21 degrees of the equator, a corridor that crosses mainly ocean but also parts of Africa, South and Southeast Asia, and Latin America.
- Most of the roughly 1,500‑kilogram spacecraft is expected to burn up on reentry, though experts warn small, dense parts such as titanium, steel, or tungsten could survive and reach the surface.
- Swift leaves a large scientific legacy—more than 2,000 gamma‑ray bursts recorded and terabytes of public data—and the incident is raising policy and engineering questions about designing satellites for controlled deorbit and reliable end‑of‑life options.
