NASA Swift observatory set to burn in Earth's atmosphere by December

Scientific American reports that orbital decay from solar storms and a failed rescue attempt will end the mission.

The short version

  • NASA's Neil Gehrels Swift Observatory is expected to enter Earth's atmosphere and burn up by December 2026 after almost 22 years in orbit.[Scientific American]
  • Strong solar magnetic storms expanded Earth's atmosphere, raising local drag and causing the gamma-ray observatory's altitude to drop faster than projected.[Scientific American]
  • A NASA-funded rescue vehicle built by Katalyst Space launched on July 3, 2026, but failed to rendezvous after losing orientation control.[Scientific American]

Key facts

  • The Neil Gehrels Swift Observatory is projected to reenter and burn up in the atmosphere no later than December 2026.[Scientific American]
  • The observatory has operated for nearly 22 years monitoring gamma-ray bursts across roughly one-sixth of the sky at once.[Scientific American]
  • Unusually powerful solar magnetic storms expanded the atmosphere, accelerating the decay of the spacecraft's orbit.[Scientific American]
  • A NASA-funded orbital rescue craft built by Katalyst Space launched on July 3, 2026, but suffered an attitude control failure and could not rendezvous.[Scientific American]

What remains uncertain

  • The exact date of reentry remains unspecified, with destruction projected to happen no later than December 2026 and potentially earlier.[Scientific American]
