And how do you plan to pay for that?By funding commercial crew at the President's requested level. As mentionned by Gerst at the House Hearing NASA intends to certify 2 commercial crew providers but should eventually have only one CTS provider. However, I suspect that there would be enough room for 2 CTS providers if NASA decided to combine crew (CTS) and cargo (CRS2). Silly me...should've thought of that. Must be the environment I work in, where "the best laid plans" just don't always get implemented due to real world constraints.I am not suggesting that you had thought of it. But there seems to be a difference of opinion between a number of Republicans (Representative Wolf and Senator Hutchison among others) and the Administration (and Senator Nelson) on the need to downselect early. I was kind of hoping that you would answer something more specific like "combining cargo and crew" wouldn't save NASA enough to fit within a budget of $500 million for commercial crew operations in 2017 (which is the predicted budget for commercial crew operations according to Gerst). Nobody has explained the logic of down selecting to only one CTS provider. If it is know for sure that maintaining 2 commercial crew providers would cost NASA twice as much, i.e., $1B per year (even if it is combined with cargo), this fact would help me and others understand the reasoning behind the decision to downselect to only one CTS provider.

And how do you plan to pay for that?And it'd be so much cheaper the other way? It's penny wise, pound foolish to down select to a single provider.Believe me, I'd personally love to see two U.S. providers, including one with horizontal landing capability for enhanced down-mass purposes. It's just not about what makes the most sense or is the most desirable when dealing with the present fiscal circumstances.

I actually think that, if cargo is also included, that you could have two qualified crew carriers.

The $60 million price tag per seat is based on what NASA pays the Russians per seat.
from what I gathered upper management has reversed cost plus into giving the plus first.......anyhow looks like they plan on downselecting to 1 & have 830M ( 2014 forward planned) roughly make 3 billion for the laucher design then pay for the seats.

Grrr......
Still, it's a shame that for us spaceplane fans, there's not much to look forward to as it's almost assured one of the capsules will win out over DreamChaser.

When asked what was the purpose of certifying two commercial crew providers if NASA only intends to select one CTS provider, Gerst said at the House hearing that they will award one CTS contract that will last from 2017 (or earlier) until 2020. But they would likely have a second contract in 2020 ("CTS2") if the ISS is extended. That second commercial crew provider could be an option for CTS2 if they are unhappy with the first provider. I suspect that the business merits evaluation will be very important in the next downselection which will occur in 2014 under phase 2 of certification. DC could end up having a stronger business case than the CST-100 in 2014. The fact that Boeing is not willing to invest in CST seems to have annoyed NASA under CCiCap. So who knows what will happen?
