EDWARDS AIR FORCE BASE, California -- Space shuttle Endeavour and its seven astronauts safely returned to Earth on Sunday, taking a detour to sunny California after storms hit the main landing strip in Florida.

Endeavour wrapped up a 16-day trip that left the international space station freshly remodeled and capable of housing bigger crews. The shuttle dropped off all kinds of home improvement equipment, including a new bathroom, kitchenette, exercise machine, two sleeping quarters and a recycling system designed to convert astronauts' urine and sweat into drinking water.

But the mission wasn't without its problems. Astronaut Heidemarie Stefanyshyn-Piper let go of a $100,000 tool bag during the first spacewalk, muttering "Oh, great" as it floated away.
