English: In Orbiter Processing Facility-1 at NASA's Kennedy Space Center in Florida, space shuttle main engine #2 is nearly in position for installation on space shuttle Atlantis for its upcoming STS-132 mission. A main engine is 14 feet long, weighs approximately 7,000 pounds, and is 7.5 feet in diameter at the end of the nozzle. Inspection and maintenance of each of the shuttle's three main engines are an important safety measure and standard procedure between shuttle missions. Atlantis is scheduled to deliver an Integrated Cargo Carrier and Russian-built Mini Research Module to the International Space Station on STS-132. The second in a series of new pressurized components for Russia, the module will be permanently attached to the Zarya module. Three spacewalks are planned to store spare components outside the station, including six spare batteries, a boom assembly for the Ku-band antenna and spares for the Canadian Dextre robotic arm extension. A radiator, airlock and European robotic arm for the Russian Multi-purpose Laboratory Module also are payloads on the flight. Launch is targeted for May 14
