All of these program could be fully funded for a year on what we spend in one week in Afghanistan.
Quote from: mike robel on 05/02/2013 09:42 pmIn my view, the fact that they are launching an Orion on a Delta IV next year means we should stop SLS development. Take the money and put it to Delta IV man rating and accelerate Orion. Any left over should be given to the company with the best chance of flying a manrated craft within the next 3 years. If we don't want to launch off of 37, then we can either crash develop the capability to launch from 39 or from 34.The goal is to either get Delta IV Heavy/Orion flying or Falcon 9/Dragon up in 36 months from contract award. Maybe its doable maybe its not. I think Gemini did it though. Surely we can do now what we did in the 60's.But I'm probably just generating wishful thinking, and the professionals will tell me I'm wrong, which is ok.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.:-)

If there were flight to cislunar with FH then it would be with a Lunar version Dragon based on the LEO crew version ( it would most likely be a commercial venture ).
Commercial crew funding by the U.S. government is an investment in a possible near future business. The small amount invested in the program could return many folds back to the U.S. goernment, plus the enhanced use of ISS ).

Yet about 7 years after COTS/CCiCAP started here we are with an ELV & spacecraft delivering cargo to the ISS, 1 getting ready to do so, 2 human rated LV's and (potentially) 3 spacecraft (1 of which has a version already flying) capable of human rating and carriage. Which suggests it can be done, but not by NASA under BAU.Who knows how much further all 3 designs could be along if they'd received what the WH and NASA asked for? I am counting 3 human rated LVs being developed with components which have already flown numerous times. There are also four human rated spacecraft under development.Which 3rd LV are you thinking of? The only 2 that I'm aware of that have ongoing work are the Atlas and Falcon.

No, they did not.
Congress needs to increase NASA's budget. And we (NASA supporters) should be letting them know this, instead of going at each other in these forums.
Quote from: Lars_J on 05/03/2013 01:55 amThey realize that the moment a commercial crew vehicle flies manned, Orion is on its death bed.The fiction that Orion is for "deep space" and commercial crew vehicles are only for LEO is easily maintainable.

Quote from: Lars_J on 05/03/2013 01:55 amWhy else would their rancor against CC keeps growing, and they make more and more outrageous statements as time passes.Because the program makes no sense and every time they ask NASA representatives leading questions they get more nonsensical answers. We've been over this.

Quote from: Lars_J on 05/03/2013 01:55 amThey realize that the moment a commercial crew vehicle flies manned, Orion is on its death bed. Why do people keep saying this? Orion is designed exclusively for BLEO missions, and CC craft are designed to be LEO taxis and freighters. If Elon ever does send a Dragon craft to Mars, it will be much different than the CC Dragons.
When spending $1+ billion per year, that fiction will have a *very* limited lifetime.
Just like a small truck is not comparable to a large truck. But hold on - I guess they *are* comparable after all. They are comparable in every metric. (Sorry, this is going off topic)
Yes, it is rather clear that one of the programs makes no sense. We seem to disagree which one, however. As for "We've been over this"...

(Sorry, this is going off topic)Then bring it back on topic.. they're not comparable because SLS and Falcon Heavy serve completely different purposes. Unless you're suggesting that Falcon Heavy can employ all the same people in the same districts as SLS, they're not comparable.QuoteYes, it is rather clear that one of the programs makes no sense.

Yea, and I'd guess there's maybe more concensus politics that maybe don't want to see a commercial provider be ready to send astronauts to space before NASA's flagship program can.
I doubt the senator from Alabama has much interest in sending money to the Ruskies over having an out-of-his-state US company do it.I think MOST wrankle at that situation, regardless of their personal turf wars.
Why the bl**dy h*ll do those d**n people from down under understand the workings of the US political system better than the average US citizen?

I can only suggest that US readers contact both their Congressman and their state Senators and make their views on this situation known to them.

I got no response from the Congressman, a form letter from one Senator, and for the other, I got a response that rhapsodized about how much the Senator was doing to bring space-related jobs to my state -- while completely failing to address the topics I had written about.
