The external tank is lowered beside the twin solid rocket boosters stacked on a mobile launcher platform for use on the mission.

In the Vehicle Assembly Building at NASA's Kennedy Space Center in Florida, the external tank for space shuttle Endeavour's STS-130 mission, ET-134, is lowered beside the twin solid rocket boosters already stacked on a mobile launcher platform in High Bay-1 for use on the mission.

Endeavour's move, or "rollover," from Orbiter Processing Facility-2 is targeted for Dec. 12. The Tranquility module, the payload for the STS-130 mission to the International Space Station, will be installed in the payload bay after the shuttle has reached the pad. Endeavour's launch is targeted for Feb. 4, 2010. For information on the STS-130 mission and crew, visit http://www.nasa.gov/mission_pages/shuttle/shuttlemissions/sts130/index.html.
