Utah based ATK was hoping to get a bid.
According to the release, the three companies are Sierra Nevada Corporation, Louisville, Colo., $212.5 million, Space Exploration Technologies (SpaceX), Hawthorne, Calif., $440 million and The Boeing Company, Houston, $460 million.
The press release stated that "CCiCap is an initiative of NASA's Commercial Crew Program (CCP) and an administration priority. The objective of the CCP is to facilitate the development of a U.S. commercial crew space transportation capability with the goal of achieving safe, reliable and cost-effective access to and from the International Space Station and low Earth orbit. After the capability is matured and expected to be available to the government and other customers, NASA could contract to purchase commercial services to meet its station crew transportation needs."
"While NASA works with U.S. industry partners to develop commercial spaceflight capabilities to low Earth orbit, the agency also is developing the Orion Multi-Purpose Crew Vehicle (MPCV) and the Space Launch System (SLS), a crew capsule and heavy-lift rocket to provide an entirely new capability for human exploration. Designed to be flexible for launching spacecraft for crew and cargo missions, SLS and Orion MPCV will expand human presence beyond low Earth orbit and enable new missions of exploration across the solar system."
