You are about to turn away from the immobile main elevator when something catches your eye. Off to one side, in the shadow of a cable bundle is a maintenance hatch for the nonworking elevator. With the proper tools that you could easily gather you could open this hatch and manually climb the interior to gain access to the ring section which holds the command center (and all the shiny, portable lab equipment just waiting to be pawned off).
This is not without danger of course. With the decreased levels of life-support it would be incredibly cold, also with no air circulation the chances of asphyxiation are greater.
