Almost exactly 22 years since it was sent into low-earth orbit by NASA, the space telescope known as the Swift Observatory has crashed, following failed efforts earlier this year to extend its time in space.

Tracking by NASA and the US Space Force showed the 1.5-ton telescope re-entering the Earth's atmosphere over Indonesia on Wednesday, November 4th. Several reports said that it burned up over Sumatra.

Since November of 2004, the observatory has focused on finding gamma-ray bursts, supernovas and other galactic explosions. With three telescopes on board, the orbiting observatory was capable of observing these events across various wavelengths, including X-ray, optical and ultraviolet light.

Though its mission was to have lasted for only two years, it was still sending observations until late October, when NASA shut down its systems.

Solar activity was considered the cause of Swift's declining orbit. After the failure of a robotic rescue mission in July, scientists resigned themselves to the fact that its long-running mission would end soon.
