Rescue Mission for NASA’s Swift Telescope Canceled After Servicer Suffers Control Failures

The failed capture ends plans to lift Swift and leaves the aging observatory vulnerable to uncontrolled reentry later this year.

Overview

  • A rapid-response commercial servicer called LINK, launched in July to grab and reboost the 2004-launched Swift observatory, developed attitude-control problems and two failed reaction wheels that forced NASA and Katalyst Space to cancel the capture-and-boost attempt.
  • With the boost abandoned, mission teams restarted Swift’s X-ray Telescope (XRT) and Ultraviolet/Optical Telescope (UVOT) to resume limited science while the Burst Alert Telescope (BAT) remains offline to conserve power and reduce drag.
  • Controllers have kept Swift in low-drag configurations and adjusted its power profile, but the observatory lacks its own propulsion so recent solar-driven atmospheric expansion has accelerated orbital decay and now puts Swift below a critical ~185-mile (300 km) threshold within weeks to months.
  • LINK will continue rendezvous and proximity demonstrations to collect engineering data on close-approach operations that could guide future in-space servicing despite its inability to perform the planned boost.
  • If Swift reenters later this year it will likely burn up, and the loss would reduce near-real-time coverage of fleeting cosmic events while shaping policy and technical plans for future commercial satellite servicing efforts.
