US space companies prepare for space station docking

Two US rocket companies are readying the first private space missions to the International Space Station (ISS).

SpaceX and Orbital both have multi-billion dollar Nasa contracts to supply cargo to the station, filling the void left by the retirement last year of the space shuttle.
