Wow. Just wow. Still reading, but my thoughts on a quick scan-through:...Just goes to show you the lengths a government agency will go to swing a competition their preferred way.

SpaceX proposes the most expensive option with the least volume and still gets selected.Although from a redundancy standpoint, Orbital ATK doesn't provide downmass, so without SpaceX NASA would have to rely on Sierra Nevada - who hasn't finished development and testing yet. So SpaceX, interestingly enough, may have been chosen as a backup to Sierra Nevada.
Both SNC and Orbital also have "acceptable" mitigation plans concerning foreign supplied engines. Presumably this isn't the entire cargo contract piling onto Falcon's. Vulcan? OA's all-solid? Curious...
According to Jeff Foust's article, the reason the SpaceX mission is the most expensive is because of the way they are comparing the missions. They are only looking at pressurized up mass. No credit is given for the down nor the unpressurized trunk cargo.http://spacenews.com/nasa-offers-more-details-on-cargo-contract-decision/
For CRS1, SpaceX was cheaper than Orbital for pressurized upmass. It is obvious that SpaceX increased their prices for CRS2.

Orbital may have very significantly lowered theirs. Given higher mass per flight and fewer flights plus less abilities. Plus they may have felt they need to lower prices to get the contract at all.The surprise is that the bid of Sierra Nevada is lowest. I cannot come up with a rationale for that.
2. It's a life or death situation for the company

SpaceX proposes the most expensive option with the least capable vehicle and still gets the highest score.*sigh*Unless you're Jim and can cram informative posts into one line, please don't. The point was that the prices don't make sense. Even with the seperate Dragon 1 and Dragon 2 production lines, SpaceX shouldn't be that expensive. RnD for Dragon 1 is done essentially (it's a mature craft) and Dragon 2s development is being funded under Com Crew.So what cost analysis did SNC and OrbitalATK give Nasa which ended up with that conclusion? Dreamchasers are freakin' expensive. Cygnus goes on Atlas.Even from superficial analysis, two and two does not make twenty two.
