NASA's Swift observatory ends 22-year mission, will crash to Earth 'in the next few weeks'

A pioneering NASA space telescope is no more. In sad news for Swifties everywhere, the Neil Gehrels Swift Observatory has officially ended its mission after more than 20 years of tracking the most powerful explosions in the universe since the Big Bang. According to a NASA announcement , the Swift team shut down the telescope's science operations Tuesday (Oct

The top 3

  1. Causes for mission termination: The mission was officially halted on October 20, 2026, after the spacecraft's orbital altitude dropped to 171 miles (275 km), making reliable cosmic observations impossible. The decay was accelerated by intense solar activity which increases atmospheric drag on satellites. A private rescue mission attempt in August 2026 failed due to hardware malfunctions before it could successfully boost the observatory's orbit.
  2. Scientific performance and operational lifespan: Designed as a two-year mission, Swift operated for 22 years, surpassing its original objectives by over a decade. It contributed to approximately 7,000 scientific papers by specializing in rapid response, allowing it to swivel within minutes to capture transient events like gamma-ray bursts, supernovas, and black-hole-related stellar destruction.
