Hubble Space Telescope Apparently in 'Safe Mode' After Gyroscope Failure

"Science operations with Hubble have been suspended while NASA investigates the anomaly", a statement from the space agency said.

Last week, the Hubble telescope stood down from observing and put itself into "safe mode" after one of its gyroscopes, which keeps it aimed at objects of scientific interest in space, died. "Everybody said OK, no big surprise, we've been expecting that for a year, let's turn on the gyro that was off at the time to get back onto science operations".

Hubble's success is due in no small part to five servicing missions flown by space shuttle crews, including an initial visit in 1993 to fix the telescope's flawed optics and the final visit in 2009 that replaced the gyros and provided additional upgrades.

Now one of the remaining three isn't working as expected, leaving Hubble with just two working gyros and it needs at least three for optimal operations. Hubble can do good science with two gyroscopes, or even one, astrophysicist Grant Tremblay, of the Harvard-Smithsonian Center for Astrophysics, said via Twitter Sunday.

"It's true. Very stressful weekend".

"The first step is to try to bring back the last gyro, which had been off, and is being problematic", Osten said on Twitter.

One newspaper quoted Rachel Osten, Hubble's deputy mission head at the Space Telescope Science Institute in Baltimore, said: "It's true".

Hubble has made more than 1.3 million observations since its mission began in 1990 and helped publish more than 15,000 scientific papers.

Astronomers have been hoping that Hubble will continue to operate long enough to cover the transition to NASA's next-generation James Webb Space Telescope.

We know that the unit has a total of six gyroscopes, because it was designed with multiple redundancy of all systems.

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

'We'll work through the issues and be back'.

NASA became aware of the issue last Friday when a gyro, already displaying "end of life" behavior, went out of action.

If that fails, chances are NASA's next plan is to run the telescope with only a single gyro. This past Friday night, Hubble was operating normally with two newer gyros and one older model. Sure, that means less sky coverage at a time.

It is named after famed astronomer Edwin Hubble who was born in Missouri in 1889. He added, "There are some things we're only going to be able to do with Hubble for the foreseeable future".
