Onboard are astronauts Scott Kelly, commander; Charlie Hobaugh, pilot; Tracy Caldwell, Rick Mastracchio, Canadian Space Agency's Dave Williams, Barbara R. Morgan and Alvin Drew, all mission specialists. Endeavour will link up with the International Space Station on Friday, Aug. 10, to begin a joint mission to continue construction by delivering a third starboard truss segment, S5, and other payloads such as the SPACEHAB module and the external stowage platform 3. The 11-day mission may be extended to as many as 14 depending on the test of the Station-to-Shuttle Power Transfer System that will allow the docked shuttle to draw electrical power from the station and extend its visits to the orbital complex.

KENNEDY SPACE CENTER, Fla. -- On an upper level of the Pad 39A fixed service structure, the STS-118 crew listen to a trainer, at left, about using the emergency egress system. The crew members are, from left, Commander Scott Kelly, Mission Specialists Tracy Caldwell, Barbara R. Morgan, Dave Williams and Alvin Drew, Pilot Charlie Hobaugh and Mission Specialist Rick Mastracchio. Williams represents the Canadian Space Agency. Morgan joined NASA's Teacher in Space program in 1985 and was selected as an astronaut in 1998. The crew is at Kennedy for training activities in the terminal countdown demonstration test, or TCDT. TCDT activities include M-113 training, payload familiarization, the emergency egress training at the pad and a simulated launch countdown. The mission is the 22nd flight to the International Space Station and Space Shuttle Endeavour will carry a payload including the S5 truss, a SPACEHAB module and external stowage platform 3.

Endeavour's main gear touched down at 12:32:16 p.m. (EDT). Nose gear touchdown was at 12:32:29 p.m. and wheel stop was at 12:33:20 p.m. Endeavour traveled nearly 5.3 million miles, landing on orbit 201. STS-118 was the 119th space shuttle flight, the 22nd flight to the station, the 20th flight for Endeavour and the second of four missions planned for 2007.

STS118-S-019 (8 Aug. 2007) --- The Space Shuttle Endeavour and its seven-member STS-118 crew head toward Earth-orbit and a scheduled link-up with the International Space Station.

Onboard are astronauts Scott Kelly, commander; Charlie Hobaugh, pilot; Tracy Caldwell, Rick Mastracchio, Canadian Space Agency's Dave Williams, Barbara R. Morgan and Alvin Drew, all mission specialists. Endeavour will link up with the International Space Station on Friday, Aug. 10, to begin a joint mission to continue construction by delivering a third starboard truss segment, S5, and other payloads such as the SPACEHAB module and the external stowage platform 3. The 11-day mission may be extended to as many as 14 depending on the test of the Station-to-Shuttle Power Transfer System that will allow the docked shuttle to draw electrical power from the station and extend its visits to the orbital complex.

From left are Shuttle Launch Director Mike Leinbach, Associate Administrator for Space Operations William Gerstenmaier, Commander Scott Kelly, Pilot Charlie Hobaugh, NASA Administrator Mike Griffin, and Mission Specialists Tracy Caldwell, Rick Mastracchio and Canadian astronaut Dave Williams. On the mission, the crew installed a new gyroscope, an external spare parts platform and another truss segment to the expanding station. Endeavour's main gear touched down at 12:32:16 p.m. EDT. Nose gear touchdown was at 12:32:29 p.m. and wheel stop was at 12:33:20 p.m. Endeavour landed on orbit 201. STS-118 was the 119th space shuttle flight, the 22nd flight to the station, the 20th flight for Endeavour and the second of four missions planned for 2007. This was the 65th landing of an orbiter at Kennedy. Photo credit: NASA/Kim Shiflett

KENNEDY SPACE CENTER, FLA. - STS-118 Pilot Charlie Hobaugh disembarks from the shuttle training aircraft, or STA, at the Shuttle Landing Facility, Kennedy Space Center's airstrip. He and STS-118 Commander Scott Kelly were at the facility to practice landings for their upcoming mission. The STA is a Grumman American Aviation-built Gulf Stream II jet that was modified to simulate an orbiter's cockpit, motion and visual cues, and handling qualities. In flight, the STA duplicates the orbiter's atmospheric descent trajectory from approximately 35,000 feet altitude to landing on a runway. Endeavour's STS-118 mission is the 22nd shuttle flight to the International Space Station. It will continue space station construction by delivering a third starboard truss segment, S5. Other payloads include the SPACEHAB module, making its last voyage, and the external stowage platform 3 with a control moment gyroscope on it. The flight will include at least three spacewalks. The crew will also debut a new system that enables docked shuttles to draw electrical power from the station to extend visits to the outpost. Launch is set for Aug. 8 at 6:36 p.m. EDT.
