July 1, 2009--- Barring any last minute "gotcha's" during post-test pad inspections, the crew of Endeavour should be able to try for liftoff a week from Saturday. The mission includes the delivery of the last section of Japan's KIBO laboratory on the International Space Station. The flight will also feature the first time two Canadians have been in space together, and one of Endeavour's rookie astronauts will be the 500th person to go into space. They're still arguing which crewmember it is ;)
