Why NASA picked Boeing over Sierra Nevada
A NASA internal document obtained by Aviation Week outlines the agency’s reasons for rejecting Sierra Nevada and its Dream Chaser spacecraft in its commercial manned space program.
Although the document praises Sierra’s “strong management approach to ensure the technical work and schedule are accomplished,” it cautions that the company’s Dream Chaser had “the longest schedule for completing certification.” The letter also states that “it also has the most work to accomplish which is likely to further extend its schedule beyond 2017, and is most likely to reach certification and begin service missions later than the other ‘Offerors’.”
Discussing costs, Gerstenmaier says that “although SNC’s [Sierra Nevada] price is lower than Boeing’s price, its technical and management approaches and its past performance are not as high and I see considerably more schedule risk with its proposal. Both SNC and SpaceX had high past performance, and very good technical and management approaches, but SNC’s price is significantly higher than SpaceX’s price.”
The document essentially was written, and probably leaked to the press now, to justify the political decision to give the contracts to Boeing and SpaceX. Thus, it waxes very enthusiastic about Boeing, since giving Boeing the contract, with the highest price and the least metal cut, needs some justification.
Readers!
My annual February birthday fund-raising drive for Behind the Black is now over. Thank you to everyone who donated or subscribed. While not a record-setter, the donations were more than sufficient and slightly above average.
As I have said many times before, I can’t express what it means to me to get such support, especially as no one is required to pay anything to read my work. Thank you all again!
For those readers who like my work here at Behind the Black and haven't contributed so far, please consider donating or subscribing. My analysis of space, politics, and culture, taken from the perspective of an historian, is almost always on the money and ahead of the game. For example, in 2020 I correctly predicted that the COVID panic was unnecessary, that the virus was apparently simply a variation of the flu, that masks were not simply pointless but if worn incorrectly were a health threat, that the lockdowns were a disaster and did nothing to stop the spread of COVID. Every one of those 2020 conclusions has turned out right.
Your help allows me to do this kind of intelligent analysis. I take no advertising or sponsors, so my reporting isn't influenced by donations by established space or drug companies. Instead, I rely entirely on donations and subscriptions from my readers, which gives me the freedom to write what I think, unencumbered by outside influences.
You can support me either by giving a one-time contribution or a regular subscription. There are four ways of doing so:
1. Zelle: This is the only internet method that charges no fees. All you have to do is use the Zelle link at your internet bank and give my name and email address (zimmerman at nasw dot org). What you donate is what I get.
2. Patreon: Go to my website there and pick one of five monthly subscription amounts, or by making a one-time donation.

Repairing Big Bertha tunneling machine. WOW! A good example of attempting to design a specialized piece of equipment to the highest level and quality, then testing it and finding that it needs to be more than what was assumed to be enough. Again, WOW!

Is Boeing was forced to go through all the same tests that everyone else is required to they would never make it off the ground.
