NASA and Katalyst Space Technologies cancel rescue mission for Neil Gehrels Swift Observatory

NASA and Katalyst Space Technologies have abandoned plans to use the LINK satellite to boost the Neil Gehrels Swift Observatory into a higher orbit due to persistent control issues. The observatory is expected to reenter Earth's atmosphere and burn up later this year, ending its 22-year science mission. The LINK satellite will instead perform a demonstration rendezvous to gather data for future satellite servicing operations.

Why It Matters

The failure of this mission marks the end of the Neil Gehrels Swift Observatory's scientific operations, which have provided critical data on cosmic events for nearly 22 years.

Key Facts

  • The LINK satellite mission to boost the Swift Observatory has been cancelled due to ongoing attitude control issues.
  • The Swift Observatory is expected to reenter Earth's atmosphere and burn up later this year.
  • The Swift Observatory has been in operation for nearly 22 years.
  • The LINK satellite will proceed with a demonstration rendezvous to test grappling and servicing capabilities.
  • The observatory is currently losing altitude due to atmospheric drag intensified by solar activity.
  • Reentry is predicted once the observatory dips below an altitude of approximately 185 miles (300 kilometers).
  • Katalyst Space Technologies designed, built, and launched the LINK satellite in nine months.
  • The LINK satellite was launched on a Northrop Grumman Pegasus XL rocket released midair from a modified L-1011 aircraft.
  • NASA does not currently have a replacement observatory for the Swift mission.
  • The mission team experienced control issues with the LINK satellite in late July, shortly after its July 3 launch.
