Cape Canaveral: The astronauts aboard the shuttle-station complex are finishing some last-minute packing.
After more than a week together, the two crews will say farewell early Friday and seal the hatches between them. Endeavour will undock from the space station Friday night.
The 11 space fliers teamed up over the past week to install a new room, Tranquility, and an observation deck at the International Space Station. Endeavour delivered the European compartments, the last of the major space station building blocks.
Mission Control congratulated the astronauts Thursday for "a docked mission of Olympic proportions." In a message, Mission Control noted, "You are officially the only folks who are able to get more hang time than Shaun White."
