PHOTOS: Shuttle Astronauts Head Home

After two weeks in space, the crew members of the Space Shuttle Endeavour are heading home. Sunday night, the shuttle undocked from the International Space Station. Here, while docked and onboard the station, an Endeavour crew member captures the glowing green beauty of the Aurora Borealis. Looking north across the Gulf of Alaska, over a low pressure area, the aurora brightens the night sky. (NASA/Reuters)
