In the Space Station Processing Facility at NASA's Kennedy Space Center in Florida, a battery charge-discharge unit is lifted by crane high above the hardware on the bay's floor. The unit is being moved toward an EXPRESS Logistics Carrier where it will be installed for flight. 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
