I thought that Hubble was kept in its orbit by small gas jets, and a gyro, maybe nuc powered. Perhaps it needs some more fuel??

And I thought that a revised shuttle is due to take off very soon, even with a female commander! Hubble should be its first mission

I heard they were gonna fly some more gasoline to Hubble, but the price was prohibitive. (/sarc)

BUMP!

Nope. Attitude pointing for hubble uses reaction wheels (spin a wheel in one direction and the spacecraft spins in the opposite), gyros (determines how far you moved), and torque rods (electromagnets that interact with Earth's magnetic field to unload momentum off the reaction wheels). Power is from solar arrays and batteries. No fuel of any kind and no nuclear power.

I may be mistaken, but I think the problem with Hubble is that it's optics need maintenance and/or replacement, and the costs/difficulties to do it. I'm totally with those who want to keep Hubble going, though.
