Space shuttle Atlantis is flying solo again.
The shuttle undocked from the International Space Station late Sunday morning after a week together.
Before departing, the six Atlantis astronauts shared some final laughs with their six colleagues at the space station.
Shuttle commander Kenneth Ham told reporters earlier in the morning that the 12 bonded through hard work and worked as a team. The space station is now bigger thanks to Atlantis and its crewmen. They left behind a new Russian compartment packed with supplies, as well as six freshly charged batteries.
Atlantis will return to Earth on Wednesday. Between now and then, the astronauts will inspect Atlantis for any damage.
