That could go both ways. SLS may be able to procure its boosters cheaper, both due to an increased volume of production and sharing overhead. The more tenants for LC-39 the less each have to pay for upkeep. I very much doubt LC-39 would be decommissioned even if SLS were canceled. If ATK makes a winning booster proposal, or even if it loses but still develops the needed tech, they can roll that into Liberty.The impact to the SLS program shouldn't be the primary selector but it shouldn't be ignored. That may seem unfair but if NASA can reduce the total amount of money it spends that is not a bad thing in my book. I'm not to warm to Liberty at this point but I am trying to keep an open mind about it. I would certainly be interested to hear more about its impacts on the SLS program. The commercial crew program's objectives should be independant of SLS/MPCV. If anything, the commercial crew program should be providing SLS/MPCV some indirect competition which could eventually drive costs down (e.g., by having Dragon or an improved CST-100 compete against Orion; or liquid boosters compete against solid boosters). Why? If the cost of both programs may be reduced and as a whole NASA would have to spend less money. I am not saying that is the case here, but these things do not exist in a vacuum. Look at the cost of the RL-10 after the SSP was shut down. The EELV program and SSP were separate. Reductions in cost due the the existence of other programs past, and present, may not be totally fair but it is an advantage. One that should be evaluated. An advantage that other competitors have already leveraged to gain CCDev funding.

It's a Lego rocket, and almost all the rest is powerpoint (except for some minor metal coupon testing).
There's a fair amount of skepticism on this thread regarding ATK, and I confess to having a lot of it myself. I have a tough time forgetting how for so many years NASA tried to transition to liquid boosters of various flavors and were prevented, even before the Shuttle ever flew. And I have a lot of resentment left over from Challenger, which is why Thiokol changed its name to ATK. Then there's X-33, wherein outside forces made composite cryogenic tanks mandatory despite the potential problems, and ATK was put in charge of those tanks despite that their team had virtually no composites experience (I'm assuming that's the same team that got the contract for the CCM, but I haven't researched it yet).* The presence of solid boosters was the reason for years of delay and expense in Constellation
I also have a question. I have the impression that ATK has been paid to develop many of the aspects of the Liberty program, and I almost wonder whether that's a business strategy on their part. I'm not faulting them; if I were their CEO, it would be my fiduciary duty to make sure the company paid as little as possible for Liberty. So my question is, what percentage of Liberty have they paid for so far and how much will they pay for if Liberty is chosen for CCiCap?

It had absolutely nothing to do with Challenger, which occurred 15 years prior.
And based on what data do you assert that it was the SRMs that caused delay and overruns on Constellation? That program may have been flawed, but do you have inside information on those flaws?
My point is not one of political conspiracy, but I can't help wondering whether ATK can win on technical merit. I also have a question.

My mistake, I was thinking of the Thiokol name change a few years after Challenger, and it's quite possible that my feelings about the accident caused me to view the name changes afterward with suspicion. My leftover Challenger resentment still stands.QuoteAnd based on what data do you assert that it was the SRMs that caused delay and overruns on Constellation?

The thrust oscillation problems and booster redesigns are well-documented.

Hercules built the canceled filament wound cases for the SRB's and was a large producer of composite structures such as Delta fairings.

Wasn't it Boeing that designed an upper stage with a natural frequency right at the SRB oscillation frequency?
Quote from: daveklingler on 07/05/2012 07:45 pm booster redesigns are well-documented.What redesigns did ATK do? They were not in charge of Ares I, NASA was the system designer, ATK only provided the first stage.
