CAPE CANAVERAL, Fla. -- The Atlantis astronauts are coming up on the end of their space station visit.
Shuttle commander Kenneth Ham told reporters Sunday morning that the two crews had a lot of fun together over the past week.
He said all 12 space fliers bonded through hard work and humor.
The astronauts will seal the hatches between Atlantis and the International Space Station later Sunday morning.
Then just before midday, the shuttle will undock and fly away.
The space station is bigger, thanks to Atlantis and its crew.
They're leaving behind a new Russian compartment packed with supplies, as well as six freshly charged batteries.
Atlantis will return to Earth on Wednesday and, as it stands now, never fly in space again.
