NASA's Swift observatory re-enters Earth's atmosphere after 22 years in orbit
NASA's Neil Gehrels Swift Observatory has come back down through Earth's atmosphere, bringing its 22-year mission to an end. The telescope was central to the study of gamma-ray bursts and other cosmic phenomena, and it recorded more than 2,000 of these bursts. Rising solar activity caused its orbit to decay, leaving the spacecraft on an uncontrolled descent. NASA made an attempt to rescue the observatory, but the effort was unsuccessful. The re-entry took place on November 4, 2026.
