NASA Calls Off Swift Telescope Rescue Mission After LINK Spacecraft Spins Out of Control

NASA’s attempt to extend the life of the Neil Gehrels Swift Observatory with the privately built LINK servicer has been abandoned. Launched in early July 2024, the mission aimed to rendezvous with Swift, capture it, and boost it from roughly 216 mi (347 km) to about 373 mi (600 km). Persistent attitude-control problems on LINK made a safe capture impossible, prompting NASA and Katalyst Space to cancel the effort. Swift will now decay naturally and re-enter Earth’s atmosphere later this year.

Swift, launched on 20 Nov 2004, is a $500 million NASA observatory that has spent two decades detecting gamma-ray bursts. Increased solar activity has expanded Earth’s upper atmosphere, raising drag and accelerating Swift’s orbital decay. To avoid an uncontrolled re-entry, NASA awarded a $30 million contract to Arizona-based Katalyst Space Technologies to build the Lightweight In-Space Navigation and Kinematics (LINK) spacecraft—a “glorified tow truck” intended to demonstrate autonomous rendezvous and satellite-servicing capabilities.

NASA Administrator Jared Isaacman said the decision does not diminish Swift’s scientific worth and noted the rapid development could advance future servicing capabilities. Katalyst CEO Ghonhee Lee described the effort as “high-risk, high-reward” and said lessons learned will inform future rendezvous and proximity operations. NASA reiterated that Swift will re-enter later this year and that LINK will continue to operate nearby to gather data for subsequent missions.

• “NASA should be willing to move quickly and take smart risks when the potential return is worth it, and that is exactly what we did with this mission,” — Jared Isaacman

The aborted rescue marks the first U.S. attempt at an on-orbit satellite boost, highlighting both the promise and difficulty of commercial in-space servicing. While Swift’s scientific contributions will end with its breakup, data from LINK’s proximity operations are expected to refine autonomous navigation, docking, and debris-mitigation techniques that could extend the lives of other aging assets.

Sources differ on Swift’s re-entry timing: some say “later this year,” others project a burn-up by the end of 2026. No definitive re-entry date or location has been provided. While all outlets agree that attitude-control failures halted the capture, details on whether both failed reaction wheels were irrecoverable vary, indicating a gap in publicly available technical diagnostics.
