A SpaceX Dragon withdrawal could leave NASA dependent on Russia for space travel, posing risks to the US space program and its access to the ISS.
Should SpaceX's Elon Musk decide to withdraw the Dragon capsule from NASA's service, the implications for the space agency would be significant.
The consequence could force NASA to depend entirely on Russia for transporting astronauts to the International Space Station.
This reliance would bring risks and limitations to the US space program's access to the ISS.
