At 11:51 a.m. EST on November 18th, Commander Charlie Hobaugh backed space shuttle Atlantis into pressurized mating adapter #2 on the International Space Station’s Harmony node. The two spacecraft were flying 220 miles above Earth between Australia and Tasmania at the time they docked.

After a series of leak checks that took about two hours, the hatches between the two vehicles opened and the two crews started their joint operations.

Right after that the shuttle and station crews held the traditional welcome ceremony. At that time astronaut Nicole Stott’s tenure as a station Expedition 21 flight engineer came to an end as she joined the Atlantis crew.
