Following a poignant farewell ceremony by the crews of Atlantis and Expedition 28, hatches between the International Space Station and a space shuttle were closed for the final time at 10:28 a.m. EDT.
The hatches between the spacecraft were open for seven days, 21 hours and 41 minutes.
Atlantis’ crew will spend the remainder of today preparing for Tuesday’s early morning undocking. The station crew goes to sleep at 1:29 p.m. and the shuttle crew follows at 1:59 p.m.
