The crew aboard the International Space Station conducted a change of command ceremony Wednesday as Expedition 22 comes to a close and two crew members prepare for an early Thursday return home.
In a brief ceremony at 8:45 a.m. EDT, Expedition 22 Commander Jeff Williams thanked the international ground teams and his fellow crewmates, Flight Engineers Maxim Suraev, Oleg Kotov, Soichi Noguchi, and T.J. Creamer, before handing over command of the station to Kotov, who will lead Expedition 23 when Williams and Suraev depart.
Afterwards, the crew wrapped up the day’s activities and headed off to bed for a 10-hour sleep period beginning at 10 a.m. to rest up for a busy night of departure work.
Williams and Suraev will bid their final farewells Wednesday at 11:40 p.m. as they climb aboard their Soyuz TMA-16 spacecraft and close the hatches. Undocking is expected to take place around 4 a.m. Thursday, leading to a 7:23 a.m. landing in the steppes of Kazakhstan.
