CAPE CANAVERAL, Fla. - In Orbiter Processing Facility Bay 3 at NASA's Kennedy Space Center in Florida, a crane lifts the gaseous nitrogen tank from space shuttle Discovery's payload bay with the aid of a "fish pole" lifting fixture. The tank is being removed during processing for the shuttle's STS-131 mission to the International Space Station. The tanks are used for atmosphere conditioning and for moving potable water in the crew module. The seven-member STS-131 crew will deliver a Multi-Purpose Logistics Module filled with science racks to be transferred to laboratories on the station. Three spacewalks will include work to attach a spare ammonia tank assembly to the station's exterior and return a European experiment from outside the station's Columbus module. This will be the 33rd shuttle mission to the station. Launch is targeted for March 18, 2010. Photo credit: NASA/Troy Cryder
