NASA's Swift Observatory reentered Earth's atmosphere on November 4, 2026, ending a 22-year mission dedicated to studying cosmic explosions. The telescope, which weighed 1.5 tons, entered the atmosphere over Indonesia's North Sumatra region after its orbit was degraded by intense solar activity. The reentry followed a failed rescue attempt in mid-2026 by Katalyst Space, a private company hired by NASA to boost the observatory's orbit; that craft crashed in September. Originally launched in 2004 for a planned two-year study, Swift far exceeded its expected lifespan, serving as a 'first responder' for detection of gamma-ray bursts and supernovae.
