Mark L. Polansky will command the shuttle Endeavour for STS-127. Douglas G. Hurley will serve as the pilot. Mission specialists are Christopher J. Cassidy, Thomas H. Marshburn, David A. Wolf and Julie Payette, a Canadian Space Agency astronaut.
The mission will deliver Timothy L. Kopra to the station as a flight engineer and science officer and return Japanese astronaut Koichi Wakata to Earth. Hurley, Cassidy, Marshburn and Kopra will be making their first trips to space.
Endeavour sets sail on its 23rd mission with the Kibo Japanese Experiment Module Exposed Facility and Experiment Logistics Module Exposed Section. The facility will provide a type of "front porch" for experiments in the exposed environment, and a robotic arm that will be attached to the Kibo Pressurized Module and used to position experiments outside the station. The mission will include five spacewalks.
STS-127 is the 29th shuttle mission to the International Space Station.
