Hubble in 'safe mode', but science operations suspended

Hubble in 'safe mode', but science operations suspended

But once more, astronomers are optimistic about Hubble's chances of recovery. The Hubble Space Telescope was designed with several redundancies in the instance of inevitable part failure.

The Hubble Space Telescope is still in "safe mode" after one of its three gyroscopes (gyros) stopped functioning.

One of NASA's most successful telescopes is in a precarious situation after a critical piece failed.

The closed gyroscope was showing signs of being worsened for almost a year, and it was not unexpected to stop the work. According to the NASA statement, the particular gyroscope that failed has been acting up for about a year.

Hubble Space Observatory has total six gyroscopes in order to keep it pointed straight at the target of which, three are of an older model and three are a newer model that was serviced during the last 2009 servicing mission.


The first part became a rescue mission: Astronauts flew the space shuttle Discovery to Hubble that December to install all new gyroscopes and a new computer.2004: Final shuttle mission canceledAfter the space shuttle Columbia disintegrated while re-entering Earth's atmosphere in 2003, NASA canceled the planned fifth and final Hubble reservicing mission. For the moment, NASA has left it out of circulation, since one of the gyroscopes stopped working last Friday, so aiming at any space object is more now hard.

Launched in 1990, Hubble has had trouble with its gyroscopes before.

The Hubble Space Telescope, NASA's jewel of the skies, is temporarily out of service. "This time will come at some point in Hubble's mission, either now or later."Shutting down the third gyroscope was expected to extend Hubble's life by only eight months, until mid-2008". In other words, it has been the most critical asset that helped scientists take a better look at the Universe that, thanks to Hubble, is a little less unknown today. The tragic destruction of Columbia in 2003 nearly made this the last Hubble visit. Staff who are from NASA's Goddard Space Flight Center as well Space Telescope Science Institute which is now performing analyses as well as tests to determine about the options that are available to recover the gyro so that it can carry the operational performance.

Since 2009, Hubble has installed six gyroscopes, three enhanced ones and three standards. "We are always anxious", says Jenkner, who has been working on Hubble since 1983.
