This Saturday, May 19th, SpaceX will attempt to become the first private company to dock a capsule with the space station. Since the Space Shuttle Columbia disaster in 2003, the White House has consistently directed NASA to turn the job of transporting cargo and crew to the station over to private firms.
NASA already has $3.5 billion in cargo contracts with two rocket makers – SpaceX and Orbital Sciences Corporation – and has added $270 million in seed money to four companies to develop technologies to transport crews. This summer, NASA expects to provide additional money to help private space companies develop full-scale systems. With SpaceX about to try for the history books, here is a rundown on the company.
Space Exploration Technologies Corporation (SpaceX) was founded in 2002 by Elon Musk, a co-founder of the online payment service, PayPal. Mr. Musk's team has developed rockets aimed at driving down the cost of launching payloads and people into space.
In 2008, after three failures, the company's two-stage Falcon 1 rocket became the first privately financed rocket to reach orbit. It launched its first satellite in 2009.
The company's next model, the Falcon 9, is designed to be the workhorse for space-station resupply missions and for launching commercial satellites. As a resupply ship, it's topped by a capsule (called Dragon) designed to carry cargo and – in the future – space-station crew members. So far, NASA has spent $75 million on the company's efforts to develop the human-transportation portion of its efforts.
Falcon 9 passed its first test launch in June 2010, topped with a dummy capsule. A second launch six months later put the company into the record books as the first privately financed rocket maker to orbit and recovery a capsule.
Liftoff of the Falcon 9 rocket, its Dragon capsule filled with food, supplies and science experiments, is scheduled for 4:55 AM ET from the SpaceX launch site at Cape Canaveral Air Force Station in Florida. Three days later, astronauts will use a robotic arm to attach the Dragon capsule to the station. The cargo will be unloaded, the return cargo loaded in, and the capsule will return to splash down in the Pacific.
As early as the end of this year, SpaceX plans to test its next rocket, the Falcon Heavy, in a launch from Vandenberg Air Force Base in
