At least NASA would only have to cover 1 companies operations overhead and not 2 or 3. What's the estimated HSF-specific operations overhead per company, and what's the expected increase in price due to lack of competition?back to the Horse RaceIMO the cost for operations and maintenance (M&O) will trump the cost to build the spacecraft, the company that shows the best M&O costs (assume safety is equal??) will be the provider/operator that can win the service contract.For operations costs over the lifetime of the spacecraft designs, sure, but I have a hard time seeing how the fixed annual HSF-specific costs of operating these spacecraft would be anywhere near the annual cost of development. I wonder how much of the opposition is based in the implicit belief that since Shuttle had huge operating costs and a standing army of thousands of people, clearly commercial spacecraft must also have huge fixed annual operating costs and a gigantic workforce. I'm personally skeptical that will be the case.

Quote from: Robotbeat on 08/08/2012 09:48 pmI know you pride yourself in having an independent opinion just for the sake of having an independent opinion, but it is not justified in this case. No money would be saved by going with just, say, Boeing (the most expensive of the three providers, going simply by launch vehicle requirements since that's the only firm thing we have to judge at this point). And just because Boeing needs 2 flights a year doesn't mean everyone else does, too.It seems crystal clear to me that paying two companies to support two production lines (and employees) for two different spacecraft and flying each at half the rate would cost more, far more, than just paying one company to do the entire job. Paying that same company to also use the same basic spacecraft production line for cargo would be even better. It would result in an American version of Russia's spectacularly successful Soyuz/Progress, which should have been the goal all along. - Ed Kyle

If you think of the future gap as something that will and can never happen (and discount all the other aspects of competition and bargaining power, etc), then sure, maybe just go for a single provider. But reality is that we will have a future gap if we don't select at least two. We apparently have enough cargo for two cargo providers, so I fail to see how we will not have enough cargo AND crew for two providers!

The U.S. has endured multiple "gaps" over the years, but NASA still exists, and U.S. astronauts continue to orbit the Earth. If a system has a problem, the best way to deal with it is to fix it and fly it promptly. Even if it funds only one commercial crew system, NASA will also have MPCV/Orion, which means that it will possess twice as many systems as any other country. - Ed Kyle

At the same time they claimed there was a "market" for all these vehicles if government would only fund their development. Note how the latter argument has quited considerably while the former has only picked up steam or at most has advocated bare minimum funding to drag out the schedule and increase risk of eventual cancellation.

Incorrect.1. If the "interests" you refer to are Bolden, Holdren, and Obama, their latest funding request gives 28% as much funding to the multiple commercial providers as to SLS and MPCV. Is that what you call "bare minimum funding?"2. Bigelow Aerospace, to name one possible alternate market, has built a new factory and is rapidly increasing its workforce after downsizing when commercial crew seemed to be less certain.
So how likely they are to meet that date depends on how close their profile is to $400m (and of course that the Legislature meets even that funding level), neither of which is known.
How many systems will China have by 2010?
Since when is our manned gap not an issue? Is it good to depend on a spiraling Soviet era system that seems to be less reliable every year?
Is SLS a viable backup for CTS? We are only building two?three by 2021? Would we just leave our people up there for 18-24 months while the next SLS is prepped?
Sorry Ed, I think you are wrong on this issue. I believe redundancy can help keep prices down, avoid gaps and strategic disasters and increase innovation which is the only long term tool to reduce cost and increase capability.

I am guessing that optimal means if they got all of the funding that the President requested ($830M per year, I believe).
My nagging issue is man rating the Atlas. Even with two companies using the launcher the numbers don’t add up. What like 1 Billion to man rate it?

I'm not aware of any human spacecraft efforts in China beyond Shenzhou.Quote Since when is our manned gap not an issue?

Soyuz is the world's most reliable rocket in current service, and it boosts the world's most reliable spacecraft in current service.Quote Is SLS a viable backup for CTS? We are only building two?three by 2021? Would we just leave our people up there for 18-24 months while the next SLS is prepped?Of course not. Soyuz could be an option, but solving whatever issue cropped up with commercial crew in a timely fashion would be the better option. It doesn't have to take two years.QuoteSorry Ed, I think you are wrong on this issue. I believe redundancy can help keep prices down, avoid gaps and strategic disasters and increase innovation which is the only long term tool to reduce cost and increase capability. I would be interested in an example of any low-use rate system that illustrates your belief. The Air Force never had redundant launch capability until EELV, which as a result costs too much. NASA in all its history has never possessed redundant crew launch capability. Neither has Russia/USSR or China. Are all of these countries wrong too? - Ed Kyle

Thanks Jim for the calcification. That makes this workable. Also makes Orion or Composite Orion very doable outside of the politics.
