NASA’s Hubble telescope has gone into safe mode.
Space officials did not say what caused the shutdown on Thursday but it comes only days after the observatory was shut down by routine maintenance.
According to a tweet from Nasa’s Hubble team: “Latest safe mode has fixed 2 out of 3 ISS anomalies.”
Earlier this week the team was blaming a crack in Hubble’s main mirror for the instrument’s safe mode troubles.
The telescope went into safe mode on 24 February due to problems with the gyroscope system.
An astronaut tried to use a spare gyroscope in place of the damaged one but the device was so confused that it unexpectedly stopped working.
The issue with that gyro was a little different because a small crack had appeared on its mirror as well.
NASA said it had fixed the problem with the telescope’s main mirror, so it should resume normal operations on Monday.
