Consider the amount of knowledge and data involved! Great if this comes through. Also to the fact that such hardware and software can be remotely changed. Also a hint to how remote maintenance can be planned for and done.

The iconic but elderly Hubble Space Telescope appears to have been resurrected again after a shutdown of more than a month following a computer glitch. Science has learned that following a switch from the operating payload control computer to a backup device over the past 24 hours, Hubble's operators have re-established communications with all the telescope's instruments and plan to return them to normal operations today.
"Hubble is back!" Tom Brown, head of the Hubble mission office, emailed to staff at the Space Telescope Science Institute at 5:56 a.m. "I am excited to watch Hubble get back to exploring the universe."
