Sierra Nevada was among the participants of a contest to select a contractor for organizing commercial delivery of astronauts for the International Space Station. It presented its R&D product at the 65th international astronautical congress, held in Toronto from September 29 through to October 3.
Boeing and SpaceX projects in the sphere of manned space flights evoked an especially big interest at the Toronto display, Dmitry Paison said. He mentioned the Dream Chaser space aircraft, the design of which incorporated some structural ideas first used by Soviet designers.
In the meantime, SierraNevada said at the end of September it would petition against the results of the contest. Its executives claimed they could spend $900 million less on its spaceship than the competitors.
At this moment, Russian Soyuz ships are the only vehicles capable of bringing the crews to the ISS and taking them back to Earth. US media reports suggest that NASA pays the Russian space agency Roscosmos about $70 million per seat aboard a Soyuz.
Bor-4 unmanned orbital rocket aircraft was used in the Buran project.
