KENNEDY SPACE CENTER, Fla. -- Two shuttle training aircraft, or STAs, wait to taxi onto the runway at the Shuttle Landing Facility. STS-118 Commander Scott Kelly and Pilot Charlie Hobaugh are each piloting one of the STAs for landing practice. The practice is part of Terminal Countdown Demonstration Test, or TCDT, activities that include a simulated launch countdown. 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. The STS-118 mission is the 22nd flight to the International Space Station and is targeted for launch on Aug. 7.

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

STS118-S-027 (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. Liftoff from Kennedy Space Center's launch pad 39A occurred at 6:36 p.m. (EDT) on Aug. 8, 2007. 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. -- In the White Room on Launch Pad 39A, STS-118 Pilot Charlie Hobaugh is helped by the closeout crew with his parachute before he enters Space Shuttle Endeavour. The outer end of the orbiter access arm ends in an environmental chamber (the White Room) that mates with the orbiter and allows personnel to enter the crew compartment. With assistance, each member of the flight crew dons a parachute pack before crawling through the open hatch into the shuttle. The closeout crew also straps the astronauts into the space shuttle's crew module and takes care of any other last-minute needs that arise. Space Shuttle 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, and other payloads such as the SPACEHAB module and the external stowage platform 3. Liftoff of Endeavour is scheduled at 6:36 p.m. EDT. Photo credit: NASA/John Kechele, Scott Haun, Tom Farrar

STS118-S-067 (21 Aug. 2007) --- Space Shuttle Endeavour approaches touchdown on runway 15 at NASA's Kennedy Space Center completing a 13-day mission to the International Space Station. Aboard are astronauts Scott Kelly, STS-118 commander; Charlie Hobaugh, pilot; Rick Mastracchio, Canadian Space Agency's Dave Williams, Barbara R. Morgan, Tracy Caldwell and Alvin Drew, all mission specialists. The STS-118 mission began Aug. 8 and 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 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.

KENNEDY SPACE CENTER, FLA. - STS-118 Pilot Charlie Hobaugh is satisfied with his training session in 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.
