EDWARDS, Calif. – Against a setting sun, space shuttle Endeavour undergoes recovery operations on Edwards Air Force Base in California after its landing. The orbiter convoy normally begins recovery operations in earnest about two hours before the shuttle is scheduled to land. Specially designed vehicles or units and a team of trained personnel “safe” the orbiter and prepare it for towing. Purge and Coolant Umbilical Access Vehicles are moved into position behind the orbiter to get access to the umbilical areas. The flight crew is replaced aboard the orbiter by exchange sup¬port personnel who prepare the orbiter for ground tow operations, install switch guards and remove data packages from any onboard experiments. After a total safety downgrade, vehicle ground personnel make numerous preparations for the towing operation, including install¬ing landing gear lock pins, disconnecting the nose landing gear drag link, positioning the towing vehicle in front of the orbiter and connecting the tow bar. The decision to land Endeavour at Edwards was made due to weather concerns at NASA's Kennedy Space Center in Florida. In the 52nd landing at Edwards, Endeavour touched down at 4:25 p.m. EST to end the STS-126 mission, completing its 16-day journey of more than 6.6 million miles in space. Endeavour will be returned to Kennedy atop a Shuttle Carrier Aircraft, or SCA, a modified Boeing 747 jetliner. Photo credit: NASA/Tony Landis, VAFB KSC-08pd3887

CAPE CANAVERAL, Fla. -- At NASA's Kennedy Space Center in Florida, this overhead image shows the Space Shuttle Program's last external fuel tank, ET-122, after it was delivered to the transfer aisle of the Vehicle Assembly Building (VAB). The tank traveled 900 miles by sea, carried in the Pegasus Barge, from NASA's Michoud Assembly Facility in New Orleans. Once inside the VAB, it eventually will be attached to space shuttle Endeavour for the STS-134 mission to the International Space Station targeted to launch Feb. 2011. STS-134 currently is scheduled to be the last mission in the shuttle program. The tank, which is the largest element of the space shuttle stack, was damaged during Hurricane Katrina in August 2005 and restored to flight configuration by Lockheed Martin Space Systems Company employees.

KENNEDY SPACE CENTER, FLA. -- The ship carrying the Experiment Logistics Module Pressurized Section for the Japanese Experiment Module arrives at the Trident wharf after departing from Yokohama, Japan, Feb. 7. The logistics module will be offloaded and transported to the Space Station Processing Facility at NASA's Kennedy Space Center. The Japanese Experiment Module is composed of three segments and is known as Kibo, which means "hope" in Japanese. Kibo consists of six components: two research facilities -- the Pressurized Module and Exposed Facility; a Logistics Module attached to each of them; a Remote Manipulator System; and an Inter-Orbit Communication System unit. Kibo also has a scientific airlock through which experiments are transferred and exposed to the external environment of space. Kibo is Japan's first human space facility and its primary contribution to the station. Kibo will enhance the unique research capabilities of the orbiting complex by providing an additional environment in which astronauts can conduct science experiments.

CAPE CANAVERAL, Fla. – SCAPE vehicles are in position at the Shuttle Landing Facility at NASA's Kennedy Space Center in Florida in the event a return-to-landing-site is needed after launch of space shuttle Endeavour on the STS-127 mission. Liftoff was on-time at 6:03 p.m. EDT. This was the sixth launch attempt for the STS-127 mission. The launch was scrubbed on June 13 and June 17 when a hydrogen gas leak occurred during tanking due to a misaligned Ground Umbilical Carrier Plate. The mission was postponed July 11, 12 and 13 due to weather conditions near the Shuttle Landing Facility at Kennedy that violated rules for launching, and lightning issues.

KENNEDY SPACE CENTER, FLA. -- The ship carrying the Experiment Logistics Module Pressurized Section for the Japanese Experiment Module is tied up at the Trident wharf after departing from Yokohama, Japan, Feb. 7. The logistics module will be offloaded and transported to the Space Station Processing Facility at NASA's Kennedy Space Center. The Japanese Experiment Module is composed of three segments and is known as Kibo, which means "hope" in Japanese. Kibo consists of six components: two research facilities -- the Pressurized Module and Exposed Facility; a Logistics Module attached to each of them; a Remote Manipulator System; and an Inter-Orbit Communication System unit. Kibo also has a scientific airlock through which experiments are transferred and exposed to the external environment of space. Kibo is Japan's first human space facility and its primary contribution to the station. Kibo will enhance the unique research capabilities of the orbiting complex by providing an additional environment in which astronauts can conduct science experiments. The various components of JEM will be assembled in space over the course of three Space Shuttle missions. The first of those three missions, STS-123, will carry the Experiment Logistics Module Pressurized Section aboard the Space Shuttle Endeavour, targeted for launch in 2007.

CAPE CANAVERAL, Fla. – Just before dawn, space shuttle Endeavour, installed on the mobile launcher platform atop the crawler-transporter, is on Launch Pad 39B at NASA's Kennedy Space Center in Florida. First motion out of the Vehicle Assembly Building was at 11:57 p.m. EDT April 16. The shuttle was secure on the pad at 7:17 a.m. EDT April 17. On the left of the shuttle is the White Room at the end of the orbiter access arm, 147 feet above the pad. When in place against the shuttle, the White Room provides access into the crew compartment on the shuttle. Endeavour will be prepared on the pad for liftoff in the unlikely event that a rescue mission is necessary following space shuttle Atlantis' launch on the STS-125 mission to service NASA's Hubble Space Telescope. After Atlantis is cleared to land, Endeavour will move to Launch Pad 39A for its upcoming STS-127 mission to the International Space Station, targeted to launch June 13.

KENNEDY SPACE CENTER, FLA. - After rollback of the rotating service structure, or RSS, on Launch Pad 39A, Space Shuttle Endeavour stands bathed in spotlights. Rollback started at 9 p.m. EDT Aug. 7 and was complete at 10:40 p.m. Beneath the shuttle is the mobile launcher platform, which spans the flame trench below. The flame deflector system includes an inverted, V-shaped steel structure that receives and deflects the flames from the orbiter main engines on one side; the opposite side deflects the flames from the solid rocket boosters. The RSS provides protected access to the orbiter for changeout and servicing of payloads at the pad. Rollback of the pad's RSS is one of the milestones in preparation for the launch of mission STS-118 at 6:36 p.m. EDT on Aug. 8. Space Shuttle Endeavour's STS-118 mission is the 22nd shuttle flight to the International Space Station.
