One week ago, more than 200 miles above the Earth, a refrigerator-size satellite making its way toward an attempted rescue of NASA's $500 million Swift gamma-ray observatory suddenly spun out of control.

It didn't look good. The spacecraft, named Link, was rotating on multiple axes, rendering it unable to maintain a reliable communications link with the ground and complicating efforts to arrest the spin. Two of the satellite's three reaction wheels, used for pointing, also stopped working. Through sporadic radio contact, engineers discovered a problem with some of the spacecraft's cold gas thrusters used for finer attitude control.

The Link satellite is built, owned, and operated by Katalyst Space Technologies, a satellite servicing startup that won a $30 million contract from NASA to fly up to the Swift observatory, grab onto it, and boost its orbit before succumbing to aerodynamic drag and burning up int he atmosphere.

Nearly a month since its launch, a first-of-its-kind commercial satellite built to save NASA's Swift gamma-ray telescope from a fiery reentry is having problems of its own, the agency announced Tuesday.

The Link satellite developed by Katalyst Space Technologies "experienced issues with attitude control" over the weekend, NASA said, causing the spacecraft to spin and resulting in sporadic communications.

"Preliminary investigation shows that two of Link's three reaction wheels currently are not operable, and there is some loss of functionality in its cold gas thruster system," NASA said.
