However, in the scheme of things, if they put Orion with a partial propellant load on an Atlas 552, they could use that for the ISS and not need commercial crew. Rather than funding Orion develop -and- 2.5 commercial crew providers that can do the same thing Orion can do.

I would much rather see Orion and the SLS cancelled than commercial crew.

The greatest cost of advanced aerospace products is wages for the employees who build the products.The conditions under which your calculation of Orion cost is accurate assume that a large team of workers involved just twiddle their thumbs 364.999 days per year drawing $800 million in salary , and when the order comes in for a new Orion it is built instantaneously at no marginal cost.In reality the program will have instead a team sized such that working only one shift a day and only 5 days a week one Orion can be built and delivered in 1 year. To first order, if 2 Orions are needed then man hour worked/ total costs roughly double, if 3 then total costs roughly triple, and so on and so forth, keeping the per unit cost roughly constant. This all assumes that the development and design cost is not factored in, which is isn't when discussing the cost to the ISS specific budget for an Orion flight. The much lauded benefits of mass production lowering per unit cost are not achieved when talking about single digit deliveries per year.So, you're saying that each Orion will cost roughly what an entire shuttle launch did, including hardware, processing, all the labor associated in that, etc.?If four Orion's were ordered in a year, it would cost roughly as much as the entire Annual shuttle budget that averaged around four launches per year in the latter years? And that's just four Orion CSM's sitting on the floor, not launching into space?Well, I gotta say, that doesn't sound quite right. But if it is, then I think NASA should close it's doors and get out of the HSF business altogether.

Are you using that "if we cancel SLS and Orion all that spare money will allow NASA to spend it on commercial and such" wishing on a star example?It's more likely that money will leave NASA for good via all those lawmakers who you know would react badly. It'd be even more ironic of the removed money ended up getting spent as "international aid" in some backwards country where they burn American flags as their national past time. Oh, if there's any money left over from paying up all the SLS/Orion contracts and making all those highly skilled American workers redundant before funding a skills program that shows them how to flip burgers in their new career at a Burger King near you.You all think money going to Russia is bad.....it could be a whole lot worse if you start waving the cancel wand all over the show."HA, very smart ass of you Chris, so what would you do?"Refine the plan. I'll set up a thread on that later

With all due respect, Chris, this is a bit of a fear-mongering argument. The NASA budget has remained fairly constant over the last couple of decades (inflation adjusted) STS was cancelled, the budget remained. CxP was cancelled, the budget remained. *If* SLS is cancelled, most of the budget will remain.The representatives won't simply give up and vote the money to other districts - they depend on being able to provide work to their districts. The trick will simply (or not so simply) be to find ways to apply new NASA projects to the centers and work forces - and the representatives will support whatever to make that happen. Easier said than done, of course.
On the Griffin, EELV and Ares I points:http://www.nasaspaceflight.com/2009/04/study-eelv-capable-orion-role-griffin-claims-alternatives-fiction/
Bingo. You beat me to it. Yes, it would mean NASA reversing policy, but how would that hurt them at this point? Obviously NASA has unofficially reversed their stance on EELV's or they'd not allow any commercial crew bidders to be proposing using EELV's to launch NASA crews to the ISS.
...Oh, if there's any money left over from paying up all the SLS/Orion contracts and making all those highly skilled American workers redundant before funding a skills program that shows them how to flip burgers in their new career at a Burger King...
....I'll take a wild stab and say because you've just eliminated SLS's only real mission, but SLS is the only programme that has to continue. You have to realize SLS supporters in the Legislature only real concern is the jobs in their districts. They have no interest in wheather it flies or not.
Nice article about the “quandary” we are in Chris! Things seemed so much simpler during the Space Race...
Honestly, if the contract becomes FAR-based, there is a good chance SpaceX might just drop out of the race. Elon has already publicly stated "we may not bid on it," if anyone's forgotten.I actually hope this happens. It will show the people in Washington that this is the wrong way of going about things.

It was in response to someone who suggested just the opposite (cancel commercial crew and do only Orion). Get it?

Simpler, but no one is seriously talking about nuking each other, so that's rather more pleasant...As much as we moan about how it slows down the first flight of commercial manned spacecraft, it means that any spacecraft that do fly are going to be really commercial, not a government contractor under a different name.
With technical issues between Orion and its launch vehicle, Ares I ...
A) So, who is NOT frustrated? B)Is there somebody who seeks power or money or the victory of wrong over right who believes that these irrational policies will further their aims?
