ScienceDaily (Oct. 29, 2012) ? A Space Exploration Technologies (SpaceX) Dragon spacecraft splashed down in the Pacific Ocean at 2:22 p.m. CDT Sunday a few hundred miles west of Baja California, Mexico. The splashdown successfully ended the first contracted cargo delivery flight contracted by NASA to resupply the International Space Station.
"With a big splash in the Pacific Ocean today, we are reminded American ingenuity is alive and well and keeping our great nation at the cutting edge of innovation and technology development," NASA Administrator Charles Bolden said. "Just a little over one year after we retired the Space Shuttle, we have completed the first cargo resupply mission to the International Space Station. Not with a government owned and operated system, but rather with one built by a private firm -- an American company that is creating jobs and helping keep the U.S. the world leader in space as we transition to the next exciting chapter in exploration. Congratulations to SpaceX and the NASA team that supported them and made this historic mission possible."
The Dragon capsule will be taken by boat to a port near Los Angeles, where it will be prepared for a return journey to SpaceX's test facility in McGregor, Texas, for processing. Some cargo will be removed at the port in California and returned to NASA within 48 hours. This includes a GLACIER freezer packed with research samples collected in the orbiting laboratory's unique microgravity environment. These samples will help advance multiple scientific disciplines on Earth and provide critical data on the effects of long-duration spaceflight on the human body. The remainder of the cargo will be returned to Texas with the capsule.
The ability to return frozen samples is a first for this flight and will be tremendously beneficial to the station's research community. Not since the space shuttle have NASA and its international partners been able to return considerable amounts of research and samples for analysis.
The Dragon launched atop a SpaceX Falcon 9 rocket from Cape Canaveral Air Force Station in Florida, on Oct. 7. It carried 882 pounds of cargo to the complex, including 260 pounds of crew supplies, 390 pounds of scientific research, 225 pounds of hardware and several pounds of other supplies. This included critical materials to support 166 scientific investigations, of which 63 were new. Returning with the Dragon capsule was 1,673 pounds of cargo, including 163 pounds of crew supplies, 866 pounds of scientific research, and 518 pounds of hardware.
The mission was the first of at least 12 cargo resupply missions to the space station planned by SpaceX through 2016 under NASA's Commercial Resupply Services contract.
SpaceX is one of two companies that built and tested new cargo spacecraft under NASA's Commercial Orbital Transportation Services (COTS) program. Orbital Sciences is the other company participating in COTS. A demonstration flight of Orbital's Antares rocket and Cygnus spacecraft to the station is planned in early 2013.
NASA initiatives like COTS and the agency's Commercial Crew Program are helping develop a robust U.S. commercial space transportation industry with the goal of achieving safe, reliable and cost-effective transportation to and from the space station and low-Earth orbit. In addition to cargo flights, NASA's commercial space partners are making progress toward a launch of astronauts from U.S. soil in the next 5 years.
While NASA works with U.S. industry partners to develop and advance these commercial spaceflight capabilities, the agency also is developing the Orion spacecraft and the Space Launch System (SLS), a crew capsule and heavy-lift rocket to provide an entirely new capability for human exploration. Designed to be flexible for launching spacecraft for crew and cargo missions, SLS and Orion will expand human presence beyond low-Earth orbit and enable new missions of exploration in the solar system.
