Goddard Space Flight Center and the Space Telescope Science Institute staff are now working out what can be done to "recover the gyro to operational performance", and an "Anomaly Review Board" has been put together to develop a recovery plan. But now NASA has been forced to place one of it's prize assets into "safe mode" due to the malfunction of a gyroscope used to balance and navigate the $2.5 billion telescope. The Hubble Space Telescope has been sidelined by a pointing system failure.
If this is not possible, then the agency will begin operating the telescope using a single gyroscope with the other working gyroscope held in reserve to preserve the overall lifetime of the telescope.
Osten also noted that the team has had a "very stressful weekend" and that the Hubble is now "in safe mode while we figure out what to do".
All six of Hubble's gyroscopes were replaced by space station astronauts during a servicing mission in 2009, but only two of those are now functioning properly.
"We'll work through the issues and be back", she promised.
"If the outcome indicates that the gyro is not usable, Hubble will resume science operations in an already defined "reduced-gyro" mode that uses only one gyro".
Dr Osten says the decision "buys lots of extra observing time" - noting that the astronomy community wanted that "desperately".
Hubble is now down to two working gyroscopes and needs at least three for optimal operations but it can continue to provide observations with just one functioning gyroscope.

Amateur astronomers have also been given access to Hubble for research purposes.
Hubble has made numerous outstanding observations of the cosmos since it was deployed in 1990. That way, Hubble has a longer total lifespan.
