Swift Telescope Set for Uncontrolled Reentry After Failed Rescue

NASA’s Neil Gehrels Swift Observatory, launched in 2004 to study gamma-ray bursts, is expected to reenter Earth in an uncontrolled descent after a private rescue mission (LINK) failed to rendezvous. Timing is uncertain, with officials saying reentry likely won’t happen before October, and most of the spacecraft is expected to burn up, though some components could survive and reach the ground. Swift’s ~613 kg dry mass and 21-degree orbital inclination mean debris could land anywhere from 21°N to 21°S, most likely in the sea; ground casualties are considered unlikely. NASA will share updates as reentry approaches.)

NASA's Van Allen Probe A Crashes in Uncontrolled Reentry Over the Pacific

An aging NASA satellite, Van Allen Probe A, reentered Earth’s atmosphere in an uncontrolled event over the Pacific after fuel depletion; most of the 600-kg spacecraft is expected to burn up, with NASA estimating a 1-in-4,200 chance of bodily harm on the ground. Its twin, Van Allen Probe B, remains in orbit and is not expected to reenter before 2030. Launched in 2012 to study the Van Allen radiation belts, the probes ceased operation after fuel ran out in 2019.
