Space Shuttle Atlantis touched down safely at 9:07am EST this morning at the Kennedy Space Center in Florida. Atlantis' landing marks the successful completion of STS-122 which saw the first new laboratory added to the station in 7 years. Columbus, Europe's contribution to the International Space Station was attached during the mission's 3 spacewalks.

What's interesting to note is the Destiny laboratory, and until this mission, the ISS' only laboratory, was launched February 7, 2001 aboard Atlantis, 7 years to the day before Columbus launched also aboard Atlantis.
