# Katalyst Space LINK spacecraft tumbling out of control after reaction wheel failures during NASA Swift Observatory mission

Canonical ID: `3d4ce76c-1e43-4779-a208-106fe2e147f1`

- **Occurred:** 2026-07-26
- **Kind:** `malfunction`
- **Status (derived):** active
- **Company:** [Katalyst Space Technologies](/companies/katalyst-space.md) (id: `e2a209b6-3cc3-4526-9d08-d38f5ce53b0c`)

On July 28, 2026, NASA and [Katalyst Space Technologies](/companies/katalyst-space.md) confirmed that the LINK spacecraft — the first commercial robotic servicing spacecraft hired by NASA to boost the Neil Gehrels Swift Observatory to a higher orbit — began tumbling out of control over the weekend. Two of the three reaction wheels that control the spacecraft's alignment have failed, and there are problems with one of the thruster systems. Flight controllers are working to recover the spacecraft using alternative thrusters to slow the spin. LINK was launched July 3, 2026 on a Northrop Grumman Pegasus rocket and was in the commissioning phase before the anomaly.
