It looks like NASA's famous Hubble Space Telescope has recovered from the glitch that knocked the observatory offline more than two weeks ago.

On Oct. 5, Hubble went into a protective "safe mode" after one of its orientation-maintaining gyroscopes failed. Mission team members tried to recruit a backup gyro, but that instrument refused to behave, returning anomalous readings.
