NASA: SpaceX's Dragon Carrying NASA Cargo Resupplies Space Station

SpaceX's Dragon Carrying NASA Cargo Resupplies Space Station
 
 
HOUSTON -- The Space Exploration Technologies Corp. (SpaceX) Dragon spacecraft was berthed to the International Space Station at 8:03 a.m. CDT Wednesday, a key milestone in a new era of commercial spaceflight. The delivery flight is the first contracted resupply mission by the company under NASA's Commercial Resupply Services contract.

"I want to congratulate SpaceX and the NASA team that worked alongside them to make this happen, and salute the astronauts aboard the space station who successfully captured the Dragon capsule," NASA Administrator Charles Bolden said. "This marks the start of a new era of exploration for the United States, one where we will reduce the cost of missions to low-Earth orbit so we can focus our resources on deep space human missions back around the moon, to an asteroid and eventually to Mars."

Space station Expedition 33 crew members Aki Hoshide of the Japan Aerospace Exploration Agency and Sunita Williams of NASA used the station's robotic arm to successfully capture Dragon at 5:56 a.m. The capture came 2 days, 10 hours, 21 minutes and after the mission's launch. The station was 250 miles above the Pacific Ocean, just west of Baja California.

Following its capture, the spacecraft was attached to the Earth-facing port of the Harmony node. The station crew could open the hatch to Dragon as early as Wednesday afternoon to begin unloading its cargo. The capsule is scheduled to spend 18 days attached to the station before returning for a splashdown in the Pacific Ocean off the Southern California coast.

Dragon delivered 882 pounds of supplies to the orbiting laboratory, including 260 pounds of crew supplies, 390 pounds of scientific research, 225 pounds of hardware and several pounds of other supplies. Dragon will return a total of 1,673 pounds, including 163 pounds of crew supplies, 866 pounds of scientific research, and 518 pounds of vehicle hardware and other hardware.

Dragon's capability to return cargo from the station is critical for supporting scientific research in the orbiting laboratory's unique microgravity environment, which enables important benefits for humanity and increases understanding of how humans can safely work, live and thrive in space for long periods. The ability to return frozen samples is a first for this flight and will be very helpful 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 spacecraft lifted off from Cape Canaveral Air Force Station in Florida at 8:35 p.m. EDT Sunday aboard a SpaceX Falcon 9 rocket. The mission was the first of at least 12 Space X cargo resupply missions to the space station through 2016. The resupply contract with NASA is worth $1.6 billion.

"Under President Obama's leadership, the nation is embarking on an ambitious space program that is bringing critical launches back to the United States, in-sourcing American jobs, and keeping the nation on the cutting edge of technology development and innovation, all the while, maintaining America's world leadership and dominance in space exploration," Bolden said.

SpaceX is one of two companies that built and tested new cargo spacecraft under NASA's Commercial Orbital Transportation Services (COTS) program. SpaceX completed its final demonstration test in May when it launched a Dragon capsule to the station and performed a series of checkout maneuvers, before Dragon was grappled by the station crew and installed on the orbiting laboratory.

Orbital Sciences is the other company participating in COTS. Orbital's Antares launch vehicle is on the launch pad at Wallops Flight Facility in Virginia. The rocket and pad will undergo a series of fueling tests that will take about three weeks. After the tests are completed, a hot fire test of the Antares first-stage engines will be conducted. A flight test of the Antares with a simulated Cygnus spacecraft will be flown in late 2012. A demonstration flight of Cygnus to the space 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.

Running well ahead of schedule, Expedition 33 Commander Suni Williams and Flight Engineer Aki Hoshide opened the hatch to the SpaceX Dragon cargo ship at 1:40 p.m. EDT Wednesday, marking a milestone for the first commercial resupply mission to reach the International Space Station.

Hatch opening had been scheduled to occur on Thursday, but the crew sped through its post-berthing procedures, enabling the earlier entrance into the cargo ship.

Earlier, Hoshide, with the assistance of Williams, used the robotic arm from a workstation inside the station’s cupola to capture Dragon at 6:56 a.m. as the spacecraft flew within about 32 feet of the station.

With Dragon securely in the grasp of Canadarm2, ground controllers remotely operated the arm to guide the capsule to the Earth-facing side of the Harmony module. Hoshide and Williams then swapped places at the controls of the robotics workstation, and Williams used the Canadian Space Agency-provided robotic arm to install Dragon to its docking port on Harmony at 9:03 a.m.

Dragon is scheduled to spend 18 days attached to the station. During that time, the crew will unload 882 pounds of crew supplies, science research and hardware from the cargo craft and reload it with 1,673 pounds of cargo for return to Earth. After Dragon’s mission at the station is completed, the crew will use Canadarm2 to detach Dragon from Harmony on October 28 and release it for a splashdown about six hours later in the Pacific Ocean, 250 miles off the coast of southern California.

Dragon launched atop a Falcon 9 rocket at 8:35 p.m. Sunday from Cape Canaveral Air Force Station in Florida, beginning NASA's first contracted cargo delivery flight, designated SpaceX CRS-1, to the station.

The third Expedition 33 crew member, Flight Engineer Yuri Malenchenko spent his day working on experiments and maintenance in the Russian segment of the station. The cosmonaut also pre-packed a Freon leak analyzer for return to Earth aboard Dragon.

Meanwhile at the Baikonur Cosmodrome in Kazakhstan, three additional Expedition 33 flight engineers -- NASA astronaut Kevin Ford, and Russian cosmonauts Oleg Novitskiy and Evgeny Tarelkin – climbed aboard their Soyuz TMA-06M spacecraft Wednesday for the first of two "fit checks" in the vehicle in which they will be launched October 23 for a five-month mission on the station.
