As with the gyroscope failures that led to the shut down of the highly successful, exoplanet-seeking, Kepler Telescope, the fabulous orbiting Hubble Telescope may be suffering the same wear-and-tear fate.
Nasa has announced that one of Hubble's gyroscopes failed last Friday. Scientific observations with the 'scope are on hold, leaving the instrument operating with only essential operating functions.
Whatever Hubble's fate might soon be, no-one can deny that the Hubble Space Telescope has been a resounding success.

Looks like Hubble has been resuscitated:

Dear al(L)
From the little I've read, the eventual fate of the Hubble Telescope seems not yet properly decided. Although it seems to me, the people in charge might well have decided more than they make public.
However, it seems probable nothing drastic will be finalised before 2020, and the HST might keep going until 2028, after which there are several possibilities; such as, keep it going even longer (?), sending it further out into space, or bringing it down toward earth then burning it up over the Pacific Ocean.

We can only wonder what the state of Hubble's main mirror could be in Cliff. Meteoritic dust and pitting from meteor strikes?

Cliff,

I don't think there is an option to keep HST going for longer after a failure - we have no way of repairing it after the retirement of the space shuttle. I though the plan was to attach a propulsion module robotically and then de-orbit it into the Pacific.

With JWST sucking up all the money there is no budget to do much else than safely de-orbit it.

I can only accept what you say. I don't have much idea myself really. I was just mentioning some ideas I picked up on the internet I think supposedly from a person, or people, involved with the HST project.
Best wishes from Cliff
