Slightly off topic-How well can the service module of the CST-100 fit the requirements for the MPCV? Is it viable?
The Atlas V has a whole new Dual engine Centaur. Don't think a dual has ever flown?
ATK's launch vehicle has never flown.
It seems to me that ATK/EADS/Lockheed Martin lost this round for the same reason Liberty lost the first round. Liberty is a good concept for a very capable rocket, and it hit political marks by using KSC and Orion "Lite", but it is too much rocket for NASA's application. More rocket equals more money that NASA doesn't have. ATK would have served NASA better by proposing fewer segments on its first stage, and a smaller upper stage.

Human rating Delta IV would be good for NASA and the country, in this process giving the choice of three launchers.
but in the end it is about reaching ISS as soon as possible. It has been very enjoyable to watch this all develop on NSF. Haven't had this type of excitement for quite some time.

Boeing and SNC will be paying ULA to finish development of the EDS and to perform testing with spacecraft simulators. Sure, but isn't NASA paying Boeing and SNC to pay ULA to do that as a sub-tier?

"If Boeing and SpaceX meet all of their self-imposed, NASA-approved milestones in the 21-month CCiCap base period, their designs for astronaut taxi systems will undergo a critical design review, the final hurdle to clear before construction can begin. Sierra Nevada’s crew transportation system would not undergo a critical design review at the end of its Space Act Agreement".I did not realize that Dreamchaser will not under go design review.http://www.spacenews.com/civil/120803-boeing-spacex-sierra-ccicap.html

Boeing and SNC could use ATK or Spacex if they wanted to.
Human Rating readiness of the F9 v1.1 and Atlas V 402/412 LV’s:EDS:ULA has designed their EDS and has developed most if not all of the associated software and tested it in the sim lab as well as a hardware form, fit and function test article. But this system has not been used on an engine or flight vehicle.SpaceX has flown their EDS on 3 F9 v1.0 vehicles (they need an EDS to perform engine out functionality). But they have not flown with the newer M1D engines.Engines and Stages:ULA has not flown a DEC on and Atlas V and has 0 experience in building such a stage (although there may be some personnel who have possibly built such a stage over 10 years ago there will likely not be many). There will be many new parts (the old ones are not available anymore) and testing will have to be done with design iterations to get to a reliable design.SpaceX has not flown a M1D on the F9 and also has not flown the much taller F9 v1.1. Some test and design iterations may occur before final design for the 9 engine thrust structure occurs. But by the time that the paperwork reviews for Human Rating occurs the F9 v1.1 will have flown as many as 10 times in a configuration that will ultimately carry humans.

Maybe not. Details are not known.

Boeing and SNC could use ATK or Spacex if they wanted to. But they're not, and the money is coming from NASA and ending up at ULA. At this time, NASA is the only customer and ULA is the only provider for these two companies' development projects.
Milestone 14: Emergency Detection System (EDS) Standalone TestingDescription: Boeing shall complete the Initial EDS Testing - LaunchVehicle Stand-alone.{redacted}Success Criteria: Completion of Initial EDS Testing - LV Stand-alonein accordance with Table G1 (Appendix 2c). Provide NASA with acopy of the test plan and a quick look summary test briefing toDocument results.
I suspect that ULA will not allow Boeing to test the Emergency Detection System unless paid. The same applies to supplying the Centaur for Milestone 8
