It's all over for Endeavour but the undocking: The shuttle's crew floated out the door this morning and closed the hatch behind them, having completed Endeavour's final mission. "We're looking forward to getting home," said commander Mark Kelly, "and we're going to leave these guys to some peace and quiet and not disturb their space station anymore." The crew will get some sleep before undocking late tonight and starting the two-day trip home, reports the AP.
The 16-day mission was Endeavour's 25th and NASA's second-to-last; the shuttle will retire to a California museum after it lands early Wednesday. Astronauts installed an extension boom for repairs and left a mountain of spare parts in an effort to prepare for the end of the shuttle program. Atlantis blasts off on its final flight on July 8.
