CAPE CANAVERAL, Fla. -- A model of the Sensor Test for Orion Relnav Risk Mitigation, or STORRM, is displayed at NASA's Kennedy Space Center in Florida. Seen here, is the International Space Station docking target and STORMM sensor enclosure assembly. A flight test of STORRM will be performed on STS-134 on the last on-orbit day of the mission, when space shuttle Endeavour will fly a dedicated maneuver to simulate an Orion rendezvous trajectory. Throughout the maneuver, two Orion sensors will collect visual- and laser-based relative navigation data. This will provide an unprecedented in-flight test opportunity for America's next-generation exploration spacecraft. STS-134 also will deliver the Express Logistics Carrier-3, Alpha Magnetic Spectrometer-2 (AMS), a high-pressure gas tank and additional spare parts for the Dextre robotic helper to the space station. Endeavour was scheduled to launch at 3:47 p.m. on April 29, but that attempt was scrubbed for at least 72 hours while engineers assess an issue associated with the shuttle's Auxiliary Power Unit 1. STS-134 will be the final spaceflight for Endeavour. For more information visit, www.nasa.gov_mission_pages_shuttle_shuttlemissions_sts134_index.html. Photo credit: NASA_Jack Pfaller
