Shuttle Endeavour departed the International Space Station on Friday night and headed home, leaving behind an outpost that is nearly complete and now has the best windows ever on the world.
The shuttle undocked as the two craft soared more than 200 miles above the Atlantic, just west of Africa's Western Sahara. The two crews spent 10 days together, working to install a new room, called Tranquility, and a domed observation deck the likes of which had never been seen before in orbit.
The compartments represented the last of the space station's major building blocks.
Mission Control told the six shuttle astronauts that they've had "an absolutely awesome mission," but now it's time to say "goodbye station, hello, Earth!" Touchdown is set for late Sunday night in Florida.
"It's been good having you. Sorry to see you guys leave," space station resident Timothy "TJ" Creamer called out as Endeavour backed away.
"We're sorry to go," replied shuttle commander George Zamka. "Hope you get to enjoy Tranquility and the new view."
