NASA's Swift Rescue Satellite Faces Attitude Control Issues
Auf einen Blick
NASA's Link satellite, designed to save the aging Swift gamma-ray telescope from reentry, is experiencing attitude control problems due to non-operable reaction wheels and cold gas thruster issues, threatening the high-stakes rescue mission.

Warum es wichtig ist
NASA's Swift Telescope, launched in 2004, is at risk of reentry without orbital adjustment.
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. [...] After reestablishing stable attitude and further investigating spacecraft status, Katalyst plans to update Link’s guidance, navigation, and control to accommodate the spacecraft’s new configuration,” NASA said. [...] Katalyst’s Link spacecraft is still generating sufficient electrical power in communication with ground teams, NASA said. That gives engineers time to develop a plan to address the reaction wheel problems.
