This is NOT about Challenger. DaveK, no more from you on this thread. You're derailing, causing lots of complaints.

You're derailing, causing lots of complaints.Let's drop my first question, since it IS derailing the thread. Apologies to anyone who's offended.My second question was:What percentage of Liberty have they paid for so far and what percentage will they pay for if Liberty is chosen for CCiCap?
Questions like that, Dave, will be good ones to add to the pile for when I schedule an interview with ATK (they have offered, so I've just got to find time to fit it inbetween the day jobs).I'm guessing they won't give specific dollar amounts, but I would assume they could provide rough percentages.When the time comes, I'll make sure I give the threads a good read to pick out some "burning" questions!
Question: if Liberty and SLS were to go ahead, is there enough similarity in the solid motor part of each vehicle that both would be grounded in the event of a serious failure of one of them?

Thank you, Chris. I'd appreciate that.I spent several hours trying to determine the answer to that question for Sierra Nevada the other day, counting up subs, trying to estimate how much each one would have been paid. It was impossible.What I did determine, though, was that even though I think CCDev has been a remarkably good deal for U.S. taxpayers in comparison to "business as usual" programs, it's still been fairly lucrative for the contractors involved. Two of them, Boeing and ATK, whom I haven't delved into with the same kind of diligence I used for SNC, seem to have leveraged a great deal of work they've done for other programs for Commercial Crew. I can't fault them for their business practices but it's weird to see their PR teams talking about all the work they've done for the good of the country.

Three people on this thread do not equate to fair amount, no matter how many times they feel they need to post on a thread.I think it's fair to assume that more than three people possess at least some degree of skepticism about ATK's claim that Liberty "provides the safest, most reliable capability to launch crews to low earth orbit for commercial space," or that it will be the "safest, most reliable, cost-effective and capable launch vehicle for crew transport," or their continued repetition of the myth that their competitors have abort blackzone problems.

They appear to have backed off of that claim, which is smart business. ...

It was in the last couple months that it was repeated very publicly and prominently. It's a bald-faced lie, and they should issue a retraction.
Perhaps there could be a technical discussion about what black zones are in another section.
When the time comes, I'll make sure I give the threads a good read to pick out some "burning" questions!

I'd like to know more about the spacecraft; most of the information and discussion seems to center on the LV. We know ATK received a "green" rating for both technical and business in the CCDev-2 evaluation, but that didn't include a spacecraft (and one reason given as to why they weren't selected). In particular:- Why didn't they propose a spacecraft as part of their CCDev-2 proposal, but are doing so now? What changed?- What are the major risk reduction efforts they feel are needed for the spacecraft before making a test flight?- As an integrated system, what's the relative split in effort between the LV vs. the spacecraft?
1. The Liberty rocket was more mature and CCDev did not discriminate on launch vehicles or spacecraft. It was up to NASA on what they wanted to fund and who had the best overall proposals from that lot2. CCiCap is an integrated end-to-end product including ground ops, flight ops, etc3. ATK is the lead and integrator for the Liberty system, which is analogous to the Dream Chaser system4. It is no secret that Lockheed Martin believes in the capabilities of Orion and believes it could do more than NASA beyond earth efforts
