CAPE CANAVERAL, Fla. – In the space Station Processing Facility at NASA's Kennedy Space Center in Florida, technicians attach the overhead crane to the pump module orbital replacement unit. The crane will lift and move the equipment to the Express Logistics Carrier 1, or ELC-1. The carrier is part of the STS-129 payload on space shuttle Atlantis, which will deliver to the International Space Station two spare gyroscopes, two nitrogen tank assemblies, two pump modules, an ammonia tank assembly and a spare latching end effector for the station's robotic arm. STS-129 is targeted to launch Nov. 12. Photo credit: NASA/Jim Grossmann

CAPE CANAVERAL, Fla. -- In the Space Station Processing Facility at NASA's Kennedy Space Center in Florida, technicians hoist the Express Logistics Carrier-4, or ELC-4, for the deck-to-keel mate. The deck is about 14 by 16 feet and spans the width of a space shuttle’s payload bay. It is capable of providing astronauts aboard the International Space Station with a platform and infrastructure to deploy experiments in the vacuum of space without requiring a separate dedicated Earth-orbiting satellite. Space shuttle Discovery and its STS-133 crew will deliver the carrier along with critical spare parts to the station later this year. Photo credit: NASA_Jack Pfaller
