After thousands of cosmic discoveries, NASA telescope faces its final countdown
FOX Weather • • general
Key Points:
- NASA's Neil Gehrels Swift Observatory conducted its final observation on October 20 and is expected to reenter Earth's atmosphere within weeks, currently orbiting less than 171 miles above the surface.
- Launched in 2004 with a two-year primary mission, Swift exceeded expectations by operating for nearly 22 years, contributing data to around 7,000 scientific papers and observing over 2,000 gamma-ray bursts and 1,400 supernovae.
- The telescope was designed for rapid detection and localization of gamma-ray bursts, enabling timely follow-up observations that revolutionized astrophysics by capturing fleeting cosmic events.
- Swift also conducted extensive multiwavelength surveys, monitored active galaxies, studied asteroids and comets, and provided an invaluable archive of data that will support future discoveries.
- NASA has officially ended efforts to extend Swift's operational life after failing to adjust its orbit, marking the conclusion of a highly successful mission that significantly advanced understanding of the dynamic universe.
