In the Vehicle Assembly Building at NASA's Kennedy Space Center in Florida, a technician is applying HD calcium grease to the field joint along the base of the left forward center solid rocket booster segment to inhibit rust and corrosion from occurring in the area.

The booster along with its twin will be stacked on the mobile launcher platform along with an external fuel tank awaiting the arrival of space shuttle Endeavour for its flight to the International Space Station. As the final planned mission of the Space Shuttle Program, Endeavour and its crew will deliver the Alpha Magnetic Spectrometer, as well as critical spare components to the station on the STS-134 mission targeted for launch Feb. 26, 2011.
