NASA ends Swift observatory science mission as low orbit and failed reboost effort close out operations

NASA has ended science operations for the Neil Gehrels Swift Observatory, which has descended to less than 171 miles (275 kilometers) above Earth. Atmospheric drag at that altitude prevents its telescopes from steadily observing targets, following a failed commercial-spacecraft attempt to raise the observatory’s orbit.

Briefing

What Hype is tracking

Swift’s science mission ends because its orbit has decayed below 171 miles (275 kilometers), where atmospheric drag prevents stable telescope observations.
The shutdown follows an unsuccessful commercial effort to reboost the aging observatory, underscoring the operational challenge of extending the life of a science spacecraft in low orbit. NASA and Katalyst Space had abandoned the servicing attempt after attitude-control problems disabled the LINK spacecraft.
