Just a quick update on Hubble here: As you may recall, a glitch within a computer system on September 27 caused it to quit most science operations, and an earlier attempt to revive it didn't work as expected. But the news is getting better: a few hours ago, the Wide Field and Planetary Camera 2 was brought up out of safe mode. A NASA status report says the camera will "resume science operations shortly." The Wide Field and Planetary Camera 2 is (as should be no surprise, given its name) very useful for studies of objects within our solar system. It's responsible for such lovely photos as this:

Mars at opposition in 2001
From the Hubble Space Telescope, Mars is a world with a diverse surface, clouds, and climate. This image was captured during Mars' opposition on June 26, 2001.

Saturn from Earth, October 1999, Ring Opening Angle 20.4 Degrees
The Hubble Space Telescope captured images of Saturn every October from 1996 to 2000. During that time, Saturn moved from southern spring to summer, and the rings opened as seen from Earth.
And don't forget this:

This animation is composed of 20 images of Vesta captured on May 14 and 16, 2007 by the Wide Field Planetary Camera 2. Vesta has a mean diameter of approximately 530 kilometers (330 miles), but is slightly shorter pole-to-pole (464 km / 288 mi) than it is at the equator (570 km / 354 mi) and rotates in 5.34 hours. The colors are not true colors but do show color variations across the surface.
And this was especially well spotted:
