The Mission at a Glance

Canadian Space Agency astronaut Julie Payette launched successfully aboard Space Shuttle Endeavour on July 15th, 2009 and returned to the International Space Station.

The Japanese robotic arm and the parts of the Kibo laboratory that will be installed by the STS-127 crew appear in the forefront.

On flight day 4, a platform was attached to the outside of the space station's Japanese Laboratory Kibo. Science experiments will take place on this platform, allowing them to remain exposed to the harsh environment of space.

The astronaut crew also delivered critical supplies to the Station, as well as experiments that will be subsequently berthed to the laboratory platform.

Julie Payette was the flight engineer. Sitting in the flight deck with the Shuttle's commander and pilot, she was part of the cockpit crew that flies the Shuttle and docks it to the space station. Payette also operated three robotic arms during this robotics-intense mission, the Shuttle's Canadarm, the Station's Canadarm2 and a Japanese arm on Kibo. Canadian robotic technology was used almost every day of this assembly mission.

For the first time in history two Canadians were in space together during this mission, Payette and Canadian Space Agency astronaut Robert Thirsk, who is part of the Station crew. A record 13 astronauts, made up of Station and Shuttle crew, were in the Station during STS-127.


The International Space Station is seen from Space Shuttle Discovery as the two spacecraft begin their separation on March 25, 2009. This is how the Space Station will appear when Julie Payette and her fellow crew members reach the orbiting laboratory this summer.

This 16-day mission included five spacewalks. After installing the laboratory platform, astronauts replaced six large batteries on a Station truss.

Mission STS-127 was the 127th mission of Space Shuttle Endeavour and the 29th to the International Space Station.
