Pratt & Whitney Rocketdyne's Space Shuttle Main Engines Deliver Hardware to Support Science Experiments Onboard the International Space Station
CANOGA PARK, Calif., November 16, 2009
Three Pratt & Whitney Rocketdyne Space Shuttle Main Engines (SSME) today successfully powered the launch of Space Shuttle Atlantis on Mission STS-129 to deliver experiments, hardware and supplies to the International Space Station (ISS). The SSME is the only fully reusable high performance rocket engine rated for human space flight. Pratt & Whitney Rocketdyne is a United Technologies Corp. (NYSE:UTX) company.
Atlantis launched from NASA's Kennedy Space Center on the 31st flight to the space station for an 11-day mission that will include three spacewalks to install two large cargo platforms called ExPRESS Logistics Carriers (ELC). The ELCs contain spare hardware that will sustain space station operations beyond 2010. The spare hardware includes two gyroscopes, two nitrogen tank assemblies, two pump modules, an ammonia tank assembly and spare equipment for the station's robotic arm.
"The International Space Station is a microcosm of life on Earth, and the scientific experiments that have been conducted aboard the station have been vital to the advancement of human health and safety, as well as the study of human impact on the environment," said Jim Paulsen, SSME program manager, Pratt & Whitney Rocketdyne. "We're proud to support NASA and the scientific community as they continue to seek new understanding of matters relevant to life on Earth."
