1. STS-118 August 8, 2007 – August 21, 2007 Space Shuttle Endeavour

2. The Crew
Front row, from the left, astronauts Alvin Drew and Barbara R. Morgan, both mission specialists, along with astronaut Scott Kelly, commander. Back row, from the left, astronauts Charlie Hobaugh, pilot, along with astronauts Tracy Caldwell, Rick Mastracchio and the Canadian Space Agency's Dave Williams, all mission specialists.

3. The Mission
Space Shuttle Endeavour's mission for this trip was to deliver a starboard truss segment to the International Space Station.

4. Successes and Failures of STS-118
Astronauts participated in a first for the space station. Mission Specialists Tracy Caldwell and Morgan installed a 7,000-pound storage platform using only the station’s and shuttle’s robotic arms.
During the spacewalks, astronauts installed the S5 truss, a gyroscope and external stowage platform 3.
Failures
Two tasks originally planned for the spacewalk – cleaning up and securing debris shielding and moving a toolbox to a more central location – were deferred to a future spacewalk due to unexpected issues that arose during the mission.

5. Interesting Fact
The launch returned Endeavour to active service after a three-year hiatus for major modifications. The work, conducted at Kennedy Space Center, included addition of a “glass cockpit,” a global positioning system for landing and the Station-to-Shuttle Power Transfer System, known as the SSPTS. The system enables the orbiter to draw power from the space station, enabling an extended stay for the mission.
