In the Space Station Processing Facility at NASA's Kennedy Space Center in Florida, a technician guides a latching end effector as it is lowered by crane toward an EXPRESS Logistics Carrier on which 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/Dimitri Gerondidakis
