Scientists May Have Figured Out Why So Many Spacecraft Were Failing

In the last 20 years it's been surprisingly common for space probes to end missions early because reaction wheels have failed, moreover there's been a large number of failures associated with a specific supplier - Ithaco. A NASA spin off which developed low cost reaction wheel systems that helped bring the cost down for many space missions.
A new study offers some clues as to what might have been going on and why solar weather might be able to damage mechanical systems.
