Reaction wheel failures leave Swift rescue mission spinning in orbit
TL;DR · WeSearch summary

Credit: Katalyst Space Technologies A camera mounted on Katalyst's Link satellite captured this view of one of its solar arrays in orbit. 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.
