American space access to re-crew the ISS will depend upon the Russians [video] under a contract valued at least $390 million from 2009 to 2011 to ferry astronauts to and from the space station. The Russians are providing no assurance that the Soyuz-taxi contract can be renewed after that. NASA is considering contracts with the Europeans and Japanese to re-supply the needs of its astronauts aboard the orbiting station. The Russians and Chinese will have the only government human-rated program in post-2010 for as long as five years.
SpaceX is seeking to achieve NASA milestones to provide a commercial space launch service that would enable both an astronaut and re-supply solution. SpaceX has yet to demonstrate flight readiness or an ability to achieve the launch rate the American space agency will need post-2010.
