Operators at NASA's John C. Stennis Space Center are completing modifications to the E-1 Test Stand to begin testing Aerojet AJ26 rocket engines in early summer of 2010. Modifications include construction of a 27-foot-deep flame deflector trench. The AJ26 rocket engines will be used to power Orbital Sciences Corp.'s Taurus II space vehicles to provide commercial cargo transportation missions to the International Space Station for NASA. Stennis has partnered with Orbital to test all engines for the transport missions.

CAPE CANAVERAL, Fla. -- Space Launch Complex 40 on Cape Canaveral Air Force Station in Florida is illuminated by a Falcon 9 rocket as it lifts off at 8:35 p.m. EDT carrying a Dragon capsule to orbit. Space Exploration Technologies Corp., or SpaceX, built both the rocket and capsule for NASA's first Commercial Resupply Services, or CRS-1, mission to the International Space Station. SpaceX CRS-1 is an important step toward making America’s microgravity research program self-sufficient by providing a way to deliver and return significant amounts of cargo, including science experiments, to and from the orbiting laboratory. NASA has contracted for 12 commercial resupply flights from SpaceX and eight from the Orbital Sciences Corp.
