30-second brief
Engineers are attempting to regain control of Katalyst Space Technologies' Link satellite after it spun out of control over 200 miles above Earth. Link was tasked with boosting NASA's $500 million Swift observatory into a higher orbit.
One-minute read
Engineers are working to stabilize the Link satellite after it spun out of control over 200 miles above Earth. Built by startup Katalyst Space Technologies under a $30 million NASA contract, the refrigerator-sized spacecraft was tasked with capturing NASA's $500 million Swift gamma-ray observatory and boosting its orbit to prevent atmospheric re-entry. During the incident, Link began rotating on multiple axes, and two of its three reaction wheels failed. Radio signals received during sporadic contact also indicated problems with its cold gas thrusters. Ground teams continue trying to restore stability and communications.
Why this matters
The failure of the Link mission could imperil NASA's $500 million Swift gamma-ray observatory, which relies on an orbital boost to remain operational in space.
Background
NASA's Swift gamma-ray observatory faces orbital decay due to atmospheric drag over time. NASA contracted Katalyst Space Technologies to deploy a servicing craft capable of grappling Swift and raising its orbit.
Key terms
- Reaction wheels
- Flywheels used on spacecraft to control attitude and pointing without using propellant.
- Cold gas thrusters

Engineers are working to regain control of a refrigerator-sized satellite named Link after it spun out of control during a mission to save NASA's Swift observatory. The spacecraft lost stability more than 200 miles above Earth, complicating efforts to maintain steady communications with ground controllers.
The Link satellite was built, owned, and operated by Katalyst Space Technologies, a satellite servicing startup. Katalyst received a $30 million contract from NASA to launch Link to rendezvous with the $500 million Swift gamma-ray observatory, capture it, and elevate its orbit before drag forces cause it to re-enter and burn up in the atmosphere.
During the spin, Link began rotating on multiple axes, causing two of its three reaction wheels used for pointing to fail. Sporadic radio contacts revealed further issues with the satellite's cold gas thrusters, which handle fine attitude control. Operations remain underway as engineers evaluate options to stabilize the craft.
