NASA turned off the science instruments aboard the Upper Atmosphere Research Satellite on June 2 after the primary solar array drive failed and its backup stopped. The array is now “parked” in a position that allows it to generate power for control and communication, but not enough to run the instruments, according to John Donley, NASA deputy project manager, Earth Science Mission Operations.

“We have a very serious problem,” said Robert J. McNeal, UARS program scientist, adding that he was nonetheless “optimistic” that it could be diagnosed and overcome.
