#Space telescope Kepler died after only four years because of reaction wheel bearing problems
Explanation of why #space telescope Kepler died after only four years: “One reaction wheel bearing manufacturer, whose RWA line was used in Kepler and FUSE, performed a relentless root cause analysis and found that these bearing failures all occurred while or just after the Sun was in the midst of violent activity. After painstaking analysis and testing, they proposed that these failures were caused by electrical arcing through the reaction wheel bearings. The huge amounts of radiation released during these solar storms were creating a voltage difference across the bearings, and when that voltage discharged, bearing damage and sometimes failure occurred. The researchers’ paper summarizing their findings can be found here.”
