NASA Pauses Most Swift Operations to Buy Time for June Reboost

Solar activity has thickened the upper atmosphere, accelerating the 21-year-old observatory’s descent toward a sub-300-kilometer danger zone.

Overview

  • NASA suspended most slewing and science activities on February 11 and placed Swift in a drag-minimizing orientation, keeping its Burst Alert Telescope active for gamma-ray burst detections.
  • Swift’s orbit has decayed from roughly 585 kilometers to below about 400 kilometers, and mission controllers aim to keep it above ~300 kilometers to enable a rescue rendezvous.
  • NASA selected Katalyst Space Technologies to mount a reboost using an air-launched Pegasus XL, currently targeted for June 2026 to rendezvous, dock, and raise Swift’s orbit.
  • The planned maneuver seeks to return the spacecraft toward ~600 kilometers, which could add years of service and demonstrate a commercial on-orbit servicing capability.
  • Without a successful reboost, forecasts point to a likely 2026 reentry, and media reports place the Katalyst contract’s value at about $30 million.
