Update: Follow live coverage of the SpaceX capsule docking onto the International Space Station here
SpaceX earned that designation and the right to undertake what NASA hopes will be regular missions to the space station and back after it completed a test flight of two astronauts earlier this year. That May launch was the first of NASA astronauts from U.S. soil since the space shuttle was retired in 2011, forcing the United States to rely on Russia for flights to orbit for nearly a decade.
