How NASA Prepares To Rescue Hubble, In Photos
Jamie pointed out a fantastic set of photos up at The Boston Globe, illustrating the painstaking preparations underway for the Shuttle mission to rescue the Hubble telescope. "This will be the final servicing mission to Hubble, the 30th flight of the 23-year old Atlantis, and one of the final 10 flights of the Space Shuttle program, which will be retired in 2010." Refreshingly, they've decided to include a many of the behind-the-scenes techies and the equipment they steward, rather than just the launch vehicles and crew.
There are also a series of vodcasts produced by NASA, one of which is "The Last Mission To Hubble". To avoid igniting a platform war, I will decline to point out a piece of software that connects to an online store that carries the NASA vodcasts, but its name is vaguely self-centered and rhymes with "die Zunes".

I'm almost not sure I want to know... I mean, machines this old, of such ridiculous complexity and with as many quirks and hacks as we are already aware of? I'm afraid I might faint at the point where it says "And now for the most important step, Chief Engineer Jim applies a fresh square of duct tape to the fuel line regulator control to keep it from jostling which could cause it to fail and the shuttle to explode. Applying a new piece of duct tape is a new procedure mandated after the Columbia disaster."
Joking of course, I do want to know, but I'd bet you anything there are some pretty scary hacks going on behind the scenes. :)

One of the big challenges of this repair mission is they're trying to actually perform a repair that the Hubble was never designed to be done. Normally components are swapped out on a module by module basis, and each module was designed to be swapped out in orbit. But this particular service mission they're going to attempt to repair a module without replacing it (because I believe there is no replacement part available). If you look at picture 12, you'll see a plexiglass apparatus designed to keep in 111 screws. That's what needs to be removed and put back in to repair this module (I think they're replacing a power supply inside the module). It all needs to be done in a vacuum, in a cramped unlit space, while wearing a space suit. Not exactly an easy mission.
