Ladies and gentlemen, we have a winner – well two, actually.
The companies will sign contracts with NASA to further develop their spacecraft to deliver astronauts to and from the ISS. Boeing will receive $4.2 billion to build its CST-100 spacecraft, a vehicle it has been working on for the past four years, while SpaceX will receive $2.6 billion to create an upgraded rendition of its Dragon spacecraft, aptly named Dragon Version 2. The original Dragon is currently being used to ferry cargo from Earth to the ISS.
The CST-100 and Dragon V2 outwardly look similar to NASA's Orion capsule, but they can both hold up to seven crewmembers each. To get to the ISS, Boeing's CST-100 will be launched on the United Launch Alliance's Atlas V rocket, and SpaceX will launch the Dragon V2 on its own Falcon 9 v1.1 rocket.
