This was the first flight under NASA's Commercial Orbital Transportation Services program, as well as the first flight of an operational Dragon spacecraft. SpaceX's first flight of a Falcon 9 rocket, in June, carried a capsule mock-up that deliberately burned up on re-entry. Last month, the Federal Aviation Administration issued its first re-entry license to SpaceX, paving the way for Wednesday's flight. SpaceX intends to fly to the space station on its very next Dragon flight, targeted for next summer. During Wednesday's mission, the capsule replicated some of the orbital maneuvers that would be needed for a station docking. Musk said he could be launching station crews within three years of getting the go-ahead from NASA. The Dragon spacecraft as well as the first stage of the Falcon 9 rockets are meant to be reusable, a long-term goal intended to save money. The company notes it will take many missions, however, to achieve that. NASA already is relying on Russia to ferry U.S. astronauts to and from the space station. It's an expensive arrangement: $26 million per person this year, rising to $51 million next year, and to $56 million in 2013. Ideally, NASA wants multiple companies to take over the job of cargo and crew transport, which would allow the agency to focus on deep-space travel to asteroids and to Mars. The effort has taken on increased significance since the working lifetime of the space station was extended to at least 2020.
NASA has just two shuttle missions remaining, in February and April. The space agency hopes to get funding for a third and final flight next summer, to restock the orbiting lab in case the commercial launch companies fall behind, before ending the 30-year shuttle program. SpaceX currently has a $1.6 billion contract with NASA for 12 supply runs. Orbital Sciences Corp. of Virginia has a $1.9 billion contract for eight. SpaceX President Gwynne Shotwell said the company has poured more than $600 million into the test flight effort so far and received $278 million from NASA. She took aim at critics, some of whom don't trust companies to provide the same level of crew safety as NASA. "I bristle a little bit at the whole concept of 'cutting corners,' " she said earlier this week. "Just because it's faster doesn't mean it's more risky." To be clear, "there were no corners cut" in this week's rocket repairs, Shotwell noted. The Falcon should have blasted off Tuesday, but two small cracks were discovered Monday in the upper-stage rocket nozzle. A technician simply cut away the nozzle extension containing the cracks, enabling the company to launch Wednesday, a day earlier than anticipated when the damage was detected. The quick repair work and grasp of the problem demonstrates the company's skill and agility, said Alan Lindenmoyer, NASA's commercial crew and cargo program manager at Houston's Johnson Space Center. "Thank you for the early Christmas present," he told SpaceX officials with a smile. ___ Online: NASA: SpaceX: http://www.spacex.com/
