Space shuttle Atlantis returned from orbit for the last time Wednesday, closing out a 25-year flying career and safely bringing back six astronauts who boosted the International Space Station's power and size. The smooth landing was indicative of the entire 12-day mission NASA's third-to-last shuttle flight. "That was pretty sweet," Mission Control radioed after Atlantis glided through a clear morning sky and rolled down the runway. "That was a suiting end to an incredible mission." Commander Kenneth Ham said he was ready to turn the shuttle over to the ground teams and get Atlantis "back in the barn for a little bit." Mission Control had monitored storms throughout the early hours, but they dissipated by daybreak and remained at a safe distance. The cockpit erupted in cheers when Mission Control finally radioed up the "go" to come home.
