KENNEDY SPACE CENTER, FLA. -- Aboard its transporter, external tank No. 117 moves into the transfer aisle of the Vehicle Assembly Building. The tank was offloaded from the Pegasus barge in the nearby turn basin. ET-117 arrived aboard the barge after its voyage around the Florida Peninsula from the Michoud Assembly Facility near New Orleans. The tank is slated for mission STS-118, which is targeted for launch in early August. ET-117 will be moved into a checkout cell in high bay 2 of the VAB for processing.

Endeavour and its STS-134 crew will deliver the Express Logistics Carrier-3, Alpha Magnetic Spectrometer, a high-pressure gas tank, additional spare parts for Dextre and micrometeoroid debris shields to the International Space Station. Endeavour's final launch is targeted for April 19 at 7:48 p.m. EDT. For more information visit, http://www.nasa.gov/mission_pages/shuttle/shuttlemissions/sts134/index.html.

CAPE CANAVERAL, Fla. -- A large yellow, metal sling lifts shuttle Endeavour from the transfer aisle into a high bay of the Vehicle Assembly Building at NASA's Kennedy Space Center in Florida. In the bay, the shuttle will be attached to its external fuel tank and solid rocket boosters. Endeavour is targeted to roll out to Kennedy's Launch Pad 39A for its final mission, STS-134, on March 9. Endeavour and the six-member crew will deliver the Express Logistics Carrier-3, Alpha Magnetic Spectrometer-2 (AMS), a high-pressure gas tank, additional spare parts for the Dextre robotic helper and micrometeoroid debris shields to the International Space Station.

STS057-03-017 (21 June 1993) --- The external fuel tank falls toward Earth after being jettisoned from the Space Shuttle Endeavour as the spacecraft headed toward its ten-day stay in Earth orbit. A 35mm camera was used to record the ET jettison.

CAPE CANAVERAL, Fla. -- Technicians and engineers will perform a walk down and detailed inspections of space shuttle Endeavour following severe storms over Launch Pad 39A at NASA's Kennedy Space Center in Florida. The frontal system moved through Central Florida producing strong winds, heavy rain, frequent lightning and even funnel clouds. During the inspections, teams found only minor damage to Endeavour's external fuel tank foam insulation and evaluations indicate there was no damage to the spacecraft. Endeavour and its six-member STS-134 crew are targeted to launch April 29 at 3:47 p.m. EDT. They will deliver the Express Logistics Carrier-3, Alpha Magnetic Spectrometer-2 (AMS), a high-pressure gas tank, additional spare parts for the Dextre robotic helper and micrometeoroid debris shields to the International Space Station. This will be the final spaceflight for Endeavour. For more information visit, www.nasa.gov/mission_pages/shuttle/shuttlemissions/sts134/index.html. Photo credit: NASA/Jim Grossmann
