CAPE CANAVERAL, FIa. -- In the Space Station Processing Facility at NASA's Kennedy Space Center in Florida, workers attach an overhead crane to the flexible hose rotary coupler. After attachment, the crane will lift and move the coupler to the Lightweight Multi-Purpose Experiment Support Structure Carrier for installation. The carrier will be installed in space shuttle Endeavour for the STS-126 mission to the International Space Station. The 15-day flight will deliver equipment and supplies to the space station in preparation for expansion from a three- to six-person resident crew aboard the complex. The mission also will include four spacewalks to service the station’s Solar Alpha Rotary Joints. Photo credit: NASA/Jim Grossmann

CAPE CANAVERAL, Fla. -- In the Space Station Processing Facility at NASA's Kennedy Space Center in Florida, a forklift moves shipping containers packed with tools and flight support equipment for orbital replacement units into a tractor-trailer for their trip to the Japanese Aerospace Exploration Agency's Tanegashima Space Center. There, the six units, including the flex hose rotary coupler, will be processed for launch to the International Space Station aboard HTV-2, scheduled for Jan. 20, 2011. HTV-2 is an uncrewed cargo transporter that will be launched by the H-IIB launch vehicle. It is designed to deliver up to 6 tons of supplies, including food, clothes and experiment devices to the space station. Photo credit: NASA/Jack Pfaller

s119e007111 (March 23, 2009) --- NASA astronaut Joe Acaba is seen during a spacewalk in March 2009. He was working on the Starboard-1 truss structure while space shuttle Discovery was docked to the station during STS-119.

S119-E-007110 (23 March 2009) --- Astronaut Joseph Acaba, STS-119 mission specialist, participates in the mission's third scheduled session of extravehicular activity (EVA) as construction and maintenance continue on the International Space Station. During the six-hour, 27-minute spacewalk, Acaba and Richard Arnold (out of frame), mission specialist, helped robotic arm operators relocate the Crew Equipment Translation Aid (CETA) cart from the Port 1 to Starboard 1 truss segment, installed a new coupler on the CETA cart, lubricated snares on the "B" end of the space station's robotic arm and performed a few "get ahead" tasks.
