Rescue Spacecraft LINK Spins Out After Reaction‑Wheel Failures

Recovery burns and guidance updates are now required with Swift’s decaying orbit narrowing the window to save the telescope.

Over the next few days, LINK will attempt to stop its spin using electric propulsion thrusters.

Overview

  • LINK entered a multi‑axis spin over the weekend after two of its three reaction wheels stopped working and its cold‑gas thruster system lost partial functionality.
  • Katalyst and NASA report the vehicle is power‑positive and intermittently in contact while teams are firing gimbaled electric (xenon) thrusters to reduce the tumble.
  • Engineers plan to update LINK’s guidance, navigation and control software for the degraded hardware and then jointly evaluate whether a safe rendezvous and grapple of Swift remains possible.
  • Swift is already in a decaying low Earth orbit of roughly 350 km and was expected to cross a ~300 km threshold by October without a boost, making the recovery effort time‑sensitive.
  • The mission was a roughly $30 million, fast‑paced commercial demonstration built in under a year to test robotic on‑orbit servicing, and its outcome will affect plans for future low‑cost satellite maintenance.
