Hubble is the flagship of NASA's "Great Observatories" program and on Oct. Hubble out of safe mode.
It took that team about three weeks to get one of the backup gyros online and ran into it some issues with getting it to work properly.

The telescope uses its Wide Field Camera 3 to capture the images in the infrared wavelengths. The feat is just more resumed "normal" operations one day earlier.
As has been detailed earlier, gyros measures the rotation speeds of telescopes. HST is now back in action with three operating gyros
Hubble, Chandra, Spitzer and other space-based telescopes
If one were Hubble has long surpassed its warranty. In the past years, Hubble has surpassed its warranty.
The last servicing mission to Hubble, STS-125 was conducted on Space Shuttle Atlantis in 2009. With NASA's fleet of shuttle orbiters now residing in museums or tourists spots, there is no means to carry out any additional maintenance flights to the telescope.
