Nasa said on Monday that the Chandra X-ray Observatory came back online on Friday.

In both cases, the problem was in the pointing system.

Officials said a glitch in one of Chandra’s gyroscopes generated three seconds of bad computer data last Wednesday.

Flight controllers restored Chandra’s pointing by switching to a backup gyroscope.

Observations are expected to resume with Chandra by the end of this week.

Hubble, meanwhile, remains out of action with a more serious gyroscope issue that cropped up on October 5.
