Mike,A few issues with this, aside from the argument about whether USAF will allow it or not.First, if you do this, cancel SLS and accelerate D4H man-rating, then what? You now have a $300-$400 million dollar 23mt crew launcher to the ISS. But Orion doesn't need to go to the ISS now because of commercial crew.(again, I think commercial crew is cool, but wholly unnecessary. Orion needed to be doing that work on an EELV launcher to get it's flight rate up to something reasonable, rather than spreading NASA's limited crew launches between 1-2 commercial crew providers, and the occasional BLEO Orion). I think that ship has sailed. There was a time that'd be a good option. But now?I think it might make more sense to cancel SLS and put Orion on FH if you are going that way, starting from the point we are now. I'm sure Elon would love Orion flying on his LV, and would cooperate fully. And I think FH will be pretty easy to man-rate, as F9 is designed from the start with HSF in mind. Delta IV is not.But even if you do that, then what?You have a 50mt crew launcher. You need more launches to do anything BLEO. You have options with Orion on FH, but you'd need at least 3 launches to put together any BLEO mission. Where do you launch 3 FH's in rapid succession from? You'll need an EDS that FH can carry, etc. etc.you can do something that way, but that's a completely different type of architecture. Again, at -this- point that would probably be a more likely way to go. Back in 2004 and 2005, D4H and it's upgrades would have been a good option. I think Orion on a man-rated Atlas, and then a 7-core Delta 4 super heavy cargo launcher (so it never needs man-rated) with big upper stage/EDS would have been a good 1.5 architecture if NASA had scaled down the CxP requirements to fit a 100mt-ish cargo launcher instead of the 125mt-ish cargo launcher Ares V started out as.But right now, I don't think D4H is the way to go for Orion. If you want to do something that way, cancel commercial crew, and man-rate Atlas 551/552 (which is already happening for commercial crew) and use Orion as the American ISS crew service spacecraft.Or...launch it on FH, and make sure Elon gets a contract to expeditiously man-rates FH in leu of getting a commercial crew contract for DRagonrider.Which again, I'm sure Elon would like and be fully cooperative on.FH with Orion can launch from a modifed existing MLP at KSC, so NASA can retain the optics.Then roll FH into a brand new multi-launch BLEO architcture.Or just stick with SLS, as it does seem to be progressing reasonably well.:-)
My feeling on this is it is imperative to get independent manned spaceflight going again.
Two things seem to be able to accomplish that in the near term: D4H/Orion and Falcon 9/Dragon. If we accelerate those programs, we might have the money to get other things that some believe gives us BLEO: Depots, DSHs, SEP engines etc.
I guess the alternative is turn off Commercial Crew and put the money into SLS/Orion so it comes on line faster and use it for the ISS Crew Rotation. The rocket and the capsule don't care where they are going.
What are we going to do with the ISS after 2020? If we splash it, are we going to replace it?
It is possible that Bigalow will launch his stations, but how big is the market for the ultra rich to go stay there?
Will NASA contract with him for services? What will we lose if we send money there?
I grant that SLS at least is trying to advance the art, while using upgraded proven systems from both Shuttle and Saturn, with a new capsule design. Will it be too little too late?
Just some thoughts. I have no answers.
letters for the most part no longer work. Get them in front of a camera and you have a little more leverage.

It's money in their districts.. who do you imagine is going to care?... Unless you're suggesting that Falcon Heavy can employ all the same people in the same districts as SLS, they're not comparable....again, we're talking about things that make sense to Congress, not space cadets.In the real world, the Orion/SLS backers in Congress are actually a vocal minority (but an influential minority). As spread out as NASA has made it, their centers/contractor still do not cover that many districts. Call it benign neglect by the rest of Congress if you wish.

[quote author=Lars_J link=topic=31803.msg1047208#msg1047208 In every subsequent appropriations act, Congress has rebuffed White House proposed cuts to Orion/SLS and increases to commercial crew. And twice, language stating the support by Congress of those two programs has been passed in the last few months. I have heard nothing from those staffers with whom I talk on Capitol Hill that indicates the support for Orion/SLS is wavering in either chamber.

Trying to outsource LEO was a bad idea politically not technically or fiscally.
You can't take funding away from NASA centers and give it to private contractors. It just creates an absolute mess and huge fights all round.
This will go on for years and NASA will be worse off for it.Commercial Crew just isn't cheap enough.
It's not buying a service, it's spending billions to develop brand new spacecraft that only have one customer.
NASA has to buy all the seats for ESA/JAXA anyway so whether it's Soyuz or Dragon capsule NASA is still the only customer.
Creating the whole industry with many working spacecraft was a pipe dream. It's now clear there's zero chance of that ever happening.
I speculate those that underfunded the initial stages of development are getting their wish.
The problem is that NASA themselves doesn't want to build cheap efficient rockets or spacecraft. They will always aim for 130mt monster launchers and spacecraft as big as they can possibly make them.
I mean look at shuttle, 7 seats, giant payload bay. If they could've made it bigger they would've.
Everything is going to come crashing down very soon if a clear, efficient, politically acceptable path isn't found soon.
The best case scenario right now is a giant rocket with no payload except a giant capsule and overpriced commercial crew seats from a single provider with an aging space station eating up more and more budget for ongoing repairs as old systems begin to degrade.
I'm disappointed, confused and I pity the American political system that values pork over progress.
But, on topic, I can't blame Congress too much for being a bit confused about that to do about this. I mean, the people here (who are relatively well informed on space stuff) don't seem to have much agreement on what the right thing to do is, either.
2. Dragons are reusable and the NASA contract specifies a new spacecraft for every launch.
3. He will have spacecraft available for commercial missions, already built and tested. I predict that commercial customers will begin to surface and will migrate to SpaceX for transportation to their desired destination. I fully expect the Bigelow stations to play a prominent role in that.
NASA may be the only customer - for now - but SpaceX is geared and funded to making sure that does not remain static. Smart guy this.
You're forgetting that Elon has stated several times that SpaceX is going to the moon MARS with or without NASA's help. NASA has become a cash cow for him for a while on 3 counts.
Apparently the AIAA is encouraging Congress to provide more funding to commercial crew. http://www.newspacewatch.com/articles/private-space-lauded-at-aiaa-meeting.html
