The first spacewalk servicing was a great success. Mission Specialists John Grunsfeld and Andrew Feustel installed the new Wide Field 3 camera, and a critical data handling computer.
This was the most important spacewalk. With these changes, Hubble is nearing good shape to provide years more science.
Tomorrow, they're going to replace the 6 gyroscopes and three batteries. The following day, they'll be installing the Cosmic Origins Spectrograph and starting attempts to repair the totally awesome ACS. After that, they'll try to repair the Space Telescope Imaging Spectrograph, add insulation, and replace the final battery.
So far so good. Keep your fingers crossed. They're gonna need a lot of luck getting ACS up and running again.
