Hubble Telescope Hit By Mechanical Failure (bbc.com)

The Hubble Space Telescope is operating with only essential functions after it lost one of the gyroscopes needed to point the spacecraft. From a report: The observatory, described as one of the most important scientific instruments ever created, was placed in "safe mode" over the weekend, while scientists try to fix the problem. Hubble had been operating with four of its six gyroscopes when one of them failed on Friday. The telescope was launched in 1990. After the gyro failure at the weekend, controllers tried to switch on a different one, but that was found to be malfunctioning. That leaves Hubble with only two fully functional gyros. At any given time, Hubble needs three of its gyroscopes to work for optimal efficiency.

It's flat, not planar you clod. There is a bottom. That's where the little people live.

Doing another maintenance run on the Hubble is probably beyond the spec/capabilities of the first manned SpaceX launch, currently planned for mid 2019.

I fear you are correct. Hubble was/is at the extreme limits of the shuttle system's ability and the last trip was risky enough that they almost didn't do it. Now we have no shuttle.

I don't doubt Space X could engineer some solution to service Hubble, but the timeframe it would take to develop the capability is likely to be longer than the scheduled replacement's arrival. To do this Hubble service thing, you need to first catch it in orbit (the shuttle used an astronaut on the robot arm for this) so you can work on it, then open it up and move around some large chunks of delicate gear from some kind of cargo area.

Given the age of Hubble, the cost of such a rescue mission and the projected replacement of the system already scheduled, I'm guessing they use Hubble as best they can with what's left that is still working. It's been a great achievement, but I don't think it's worth it at this point to try and fix the thing. Besides, we all knew the day would come when Hubble would work no more. It's sad, but the time may be closer than we would like to admit.
