Some welcome news from the Hubble team.
The team successfully restored HST to science operations yesterday April 29. HST is now operating with all 3 gyros; all instruments and computer systems are online and in good health.
The blog post does not specify the nature of the problem with the ailing gyro or the fix. The spacecraft had entered safe-mode on April 23 when one of the 3 healthy gyros started giving faulty readings.
