The big news today is that Robert Bigelow has announced the rules for America's Space Prize, a $50 million cash prize for the design and manufacture of a space capsule suitable for resupply of Bigelow space stations. Please see the Space.com article. Here are the rules, in brief.
(1) The spacecraft must reach a minimum altitude of 400 kilometers (approximately 250 miles);
(2) The spacecraft must reach a minimum velocity sufficient to complete two (2) full orbits at altitude before returning to Earth
(3) The spacecraft must carry no less than a crew of five (5) people;
(4) The spacecraft must dock or demonstrate its ability to dock with a Bigelow Aerospace inflatable space habitat, and be capable of remaining on station at least six (6) months;
(5) The spacecraft must perform two (2) consecutive, safe and successful orbital missions within a period of sixty (60) calendar days, subject to Government regulations;
(6) No more than twenty percent (20 percent) of the spacecraft may be composed of expendable hardware;
(7) The spacecraft must complete its two (2) missions safely and successfully, with all five (5) crew members aboard for the second qualifying flight, before the competition’s deadline
(8) The contestant must have its principal place of business in the United States of America.
(9) The Competitor must not accept or utilize government development funding related to this contest of any kind, nor shall there be any government ownership of the competitor. Use in government test facilities shall be permitted.
(10) The spacecraft must complete its two (2) missions safely and successfully, with all five (5) crew members aboard for the second qualifying flight, before the competition’s deadline of Jan. 10, 2010.
As stated before, this prize is tailor-made for SpaceX. I don't know any other company that is on this kind of tight design trajectory.
