cabin that both reduces weight and increases safety of astronauts. This was later revealed to be a part of a larger system, designed for a biconic capsule, that would be launched atop an Atlas V rocket. On November 8, 2010, it was announced that Blue Origin had completed all milestones under its CCDev Space Act Agreement. In April 2011, Blue Origin received a commitment from NASA for of funding under the CCDev phase 2 program. Milestones included (1) performing a Mission Concept Review (MCR) and System Requirements Review (SRR) on the orbital Space Vehicle, which utilizes a biconic shape to optimize its launch profile and atmospheric reentry, (2) further maturing the pusher escape system, including ground and flight tests, and (3) accelerating development of its BE-3 LOX/LH2 engine through full-scale thrust chamber testing. In 2012, NASA's Commercial Crew Program released its follow-on CCiCap solicitation for the development of crew delivery to ISS by 2017. Blue Origin did not submit a proposal for CCiCap, but is reportedly continuing work on its development program with private funding. Blue Origin had a failed attempt to lease a different part of the Space Coast, when they submitted a bid in 2013 to lease Launch Complex 39A (LC39A) at the Kennedy Space Center – on land to the north of, and adjacent to, Cape Canaveral AFS – following NASA's decision to lease the unused complex out as part of a bid to reduce annual operation and maintenance costs. The Blue Origin bid was for shared and non-exclusive use of the LC39A complex such that the launchpad was to have been able to interface with multiple vehicles, and costs for using the launch pad were to have been shared across multiple companies over the term of the lease. One potential shared user in the Blue Origin notional plan was United Launch Alliance. Commercial use of the LC39A launch complex was awarded to SpaceX, which submitted a bid for exclusive use of the launch complex to support their crewed missions. In September 2013 – before completion of the bid period, and before any public announcement by NASA of the results of the process – Florida Today reported that Blue Origin had filed a protest with the U.S. General Accounting Office (GAO) "over what it says is a plan by NASA to award an exclusive commercial lease to SpaceX for use of mothballed space shuttle launch pad 39A".
