I bet all the New Space fans amongst the Presidential Advisers are happy too, funnily enough they got exactly the result they wanted too . I wonder though if this is really the end of it, will ATK's fans in Congress now try to engineer a 180 and try to enlarge CCiCAP to also include ATK, all in the interest of maximizing full commercial competition of course . Will the SLS fans there go along with it if they do if it means it comes out of their budget ?

I think it will be very hard for them to appeal.....

I looked up the flight history and Atlas V has never flown a dual engined Centaur.

ATK's test flight date matched SpaceX and all their hardware already exists in one form or another so they may have good grounds for complaining here. An engine, body, transmission, some seats, a steering column and tires lying on the floor does not make a car. For instance Dragon, Dream chaser, and CST-100 have tested Abort engines and have selected their TPS. CST and Dragon their Parachutes Dreamchaser landings later this month or next. Dragon has flown into space. Dragon, Dream chaser and CST-100 use an existing rocket. The liberty capsule has none of that going for it. Liberty is not an existing rocket (in fact that alone adds much risk and not much reward). ATK has much more risk of slip and much more risk of long slips than any of the three above. If they sue(which is their right) they will be laughed out of court.
Liberty has ATK, Lockheed Martin and Astrium behind it all basically integrating and adapting either existing or soon to exist hardware and software, the risks of failure or slippage are low and the rocket concept has already been demonstrated with Ares I-X. NASA was also not that concerned about new rocket risk when it deliberately chose SpaceX and Orbital over lower risk COTS proposals which used existing Atlas/Delta rockets. Seems the rules of the game change on the whims of whoever the current political masters are.
Yes ATK is the nominal prime but you don't think it will listen to say LM/Astrium's greater experience when it has to ? In reality ATK would only be contributing the SRB and the composite capsule, LM and Astrium would be doing the serious work of outfitting the capsule and integrating and controlling the rocket.
Although MMOD density *is* a function of altitude (more at higher altitudes), I was actually referring to attitude, not altitude. i.e. whether X-37 was flying tail-forward to minimize cross-sectional area exposed to the velocity vector. We don't have (at least publicly) data on the attitudes that X-37 flew.

I expect to see videos of actual Dragon hardware landing on a pad in Texas sometime in the next 24 months.
All 4 proposals should be fully funded until they either succeed or fail.Congress should think again and find the money to give SNC an extra ~$200m and ATK ~$400m and take it out of SLS's hide if necessary, it will still live on in all its future glory regardless. We have waited this long for Saturn/Apollo's successor we can wait a little longer to help a more immediate great cause as long as we know SLS is coming eventually.

Seems the rules of the game change on the whims of whoever the current political masters are.Whew that was a good one marsavian, I need a good laugh in the mor....oh crap you were actually serious? Even in the best of cases adapting hardware from completely different systems for roles they were not originally meant to play has a lot more schedule and cost risk than the proponent is willing to admit to up front...And yes, SpaceX and OSC were selected for COTS instead of vehicles flying on existing LVs such as Atlas/Delta. As many pointed out at the time, this was likely Mike Griffin's thumbs on the scales to prevent something flying on Atlas making Ares-I look bad, while also to simultaneously find a replacement for the then-soon-to-be-retired Delta II. I actually think that they took on more risk than they should've by funding both SpaceX and OSC to build new launchers plus new capsules, and would've been better off picking at most one of the "first we build a new rocket" crowd, and then using the savings from not funding a rocket to fund two other COTS teams. My guess is COTS would be all the way done by now if they had done so.~Jon

Most destination discussion for these 3 has been ISS, some commercial destination (Bigelow etc..) and other later possible NASA destinations.I can't help feeling that after "progress" the Air Force will be very interested in these craft. When one considers their little X-demo craft flitting about SNC's craft might interest them more. If the Air Force is interested one could well imagine more funds available for development than the NASA awards imply. Some of these funds might well be black and therefore lead to surprise development achievements not expected when one looks at the published funding.
