SpaceRef.com posted NASA's November 1 announcement that the final round of commercial crew competition begins this month.
Known as Commercial Crew Transportation Capability (CCtCap), this “is the second phase of a two-phased procurement strategy to develop a U.S. commercial crew space transportation capability to achieve safe, reliable and cost effective access to and from the International Space Station (ISS) with a goal of no later than 2017.”
According to the announcement, NASA intends to release the Request for Proposals around November 19, with proposals due on January 22. Kennedy Space Center will hold a pre-proposal conference on December 4.
These dates are, of course, subject to the whims of Congress.
