Looks like SSA rated SpaceX as number 1 overall, even thou SEB and SSA tried to make non-issues into issues. I got great respect for both Boeing and SpaceX and have no doubt that they will be able to launch crew to ISS in 2017. It is a pity that SNC didn't make the cut, but I think it was the right call. Hopefully they will find funding elsewhere and finish the Dream Chaser.

Hopefully they will find funding elsewhere and finish the Dream Chaser.They found Boeing to be the strongest proposal, although their language obfuscates it a bit. The GAO statement summarized it more clearly than NASA:"Specifically, NASA recognized Boeing’s higher price, but also considered Boeing’s proposal to be the strongest of all three proposals in terms of technical approach, management approach, and past performance, and to offer the crew transportation system with most utility and highest value to the government."
Does anyone have any details about what this alternate launch vehicle was? It's not clear to me that "new launch vehicle" just means new-to-Boeing, or an actual new launch vehicle?

Boeing said early in the Commercial Crew program that their CST-100 would be compatible with Falcon 9 and that they could pursue that in parallel with the Atlas V.See, for example, this article and this previous thread.

I don't see a way they could have a BE4 powered Atlas ready by 2017, 2018 or even 2019.
Found this statement of interest:"Boeing proposed to pursue an alternate launch vehicle in parallel with their baseline design work. Thisnew launch vehicle, if used in the CTS design, provides alternatives but would negate thebenefits of the established reliability of the existing launch vehicle. "Does anyone have any details about what this alternate launch vehicle was? It's not clear to me that "new launch vehicle" just means new-to-Boeing, or an actual new launch vehicle?
The new vehicle Boeing speaks of is the Atlas replacement, which will not be ready before the decade is out but is something they are already working on for certification.
Interesting that Boeing got good marks for landing capability (parachutes and air bags in the desert), and SNC did not win special favor by landing horizontally on a runway, nor SpaceX for pinpoint landing anywhere.
Boeing received strengths for its: 1) primary landing sites;
SpaceX's proposal had strengths for its: [...] 4) landing system availability opportunities.
SNC's proposal had strengths for its: [...] 3) co-location of launch and recovery operations;
The only new manrated vehicle they could refer to would be the Falcon 9.
Tony Bruno became President of ULA in August, and Boeing has been saying that they could use Falcon 9 for quite a long time...... but Falcon 9 would always be a possible backup they could point to.

If you don't, then please don't phrase your statement as an assertion of fact.
Boeing Technical: .... The launch vehicle has demonstrated reliability and well-known failure modes and operating environments, which facilitates an integrated abort system for a crewed system and results in a safer launch vehicle. Both of these elements of the CTS design solution reduce technical and schedule risk and increase ability to meet safety requirements for human spaceflight. I also recognized that Boeing proposed to pursue an alternate launch vehicle in parallel with their baseline design work. This new launch vehicle, if used in the CTS design, provides alternatives but would negate the benefits of the established reliability of the existing launch vehicle.
A new LV, which likely relies on the new liquid engine program, at least explains the difference in costs.
Perhaps one day Atlas/Delta/SLS will be consolidated and the US will have two non sole source LVs...
Here is the full GAO decision (21 pages) on the SNC protest:http://www.gao.gov/assets/670/667979.pdf
Perhaps one day Atlas/Delta/SLS will be consolidated
In addition to the new LV, Boeing uses the old LV (Atlas?) that is no longer allowed to support the DOD.
1. A new LV, which likely relies on the new liquid engine program, at least explains the difference in costs.2. So by the sole source document alone, Altas is not specified....neither is Falcon or CST-100...
