At NASA's Kennedy Space Center in Florida, a crawler-transporter moves a mobile launcher platform with two solid rocket boosters perched on top from the Vehicle Assembly Building's (VAB) High Bay 1 to High Bay 3.

Inside the VAB, the boosters will be joined to an external fuel tank next month in preparation for space shuttle Endeavour's STS-134 mission to the International Space Station targeted to launch in February, 2011.
