NASA Ends Swift Observatory Mission Following Unsuccessful Orbit Maneuver

NASA has concluded the Neil Gehrels Swift Observatory's science mission on October 23, 2026, after a privately developed spacecraft failed to raise its orbit. The observatory collected its final data on October 20, 2026, and is expected to re-enter Earth's atmosphere soon. This marks the end of a 21-year mission that provided crucial data on gamma-ray bursts and other cosmic phenomena.
