SpaceX is a leading private space flight company that aims to use its Falcon 9 rocket to rendezvous a Dragon space capsule with the International Space Station, fulfilling a $1.6 billion commercial cargo contract. If successful, it would be the first private sector delivery to the space station. SpaceX specializes in cargo delivery services and hopes to eventually promote space tourism, but it faces competition from other private players like Boeing, Blue Origin, and Sierra Nevada in developing technologies for private space flight.
