Astronauts complete tough mission

摘要

The Space Shuttle Atlantis touched down safely in the pitch black of an early Florida morning on 21 September 2006 ending a 12 day mission to re-start construction of the International Space Station (ISS). "Nice to be back. It was a great team effort and assembly is off to a good start," said commander Brent Jett after the landing. It was the third safe re-entry since Columbia disintegrated during its attempted landing in February 2003 after its heat-shielding was compromised by debris that struck that vehicle during launch.
