Hubble Space Telescope fixed after month of no science

CAPE CANAVERAL, Fla. — The Hubble Space Telescope should be back in action soon, following a tricky, remote repair job by NASA.

The orbiting observatory went dark in mid-June, with all astronomical viewing halted. NASA initially suspected a 1980s-era computer as the source of the problem. But after the backup payload computer also failed, flight controllers at Maryland’s Goddard Space Flight Center focused on the science instruments’ bigger and more encompassing command and data unit, installed by spacewalking astronauts in 2009.
