CEV to be made commercially available
Right now NASA is in quite a bit of a funding crisis. It seems it can't afford to keep flying the shuttle for ISS assembly flights and start CEV and stick development at the same time on its existing budget. They're not about to compound that development effort (and increase the development costs by billions) just to recover a few SSME's or start a LEO junkyard made up of spent upper stages
They would not need to spend a single dime to do so. You want the SSME? Go get it. Can't be bothered to go get it? Then don't bitch that it's not reusable. How many times has *any* spent upper stage or launch vehicle engine that's in LEO, been recovered or reused? How many fully resuable launch vehicles have flown? How many times have commercial spacecraft launched passengers into orbit? I guess they're all jsut impractical or even impossible.... their lunar mission architecture requires only a single docking in LEO before departing for the moon. Good for them! But bad for anyone proposing a use for spent upper stages. Hardly. Teh stage is there. You want it? Go get it. If you want to develop EVA procedures and tech... there's your chance. However, those spent stages will still be property of the US government, so they really will need permission to do anything with them. There's your first chance to do something. Get title transferred once the stage is abandoned. Resorting to name calling in a debate is always telling. So is the whining I'm seeing so often. Don;t like being called a whiner? Stop whining. Come up with somethign productive. I'm just being realistic. No, you're being defeatist. But if you're so convinced this is a viable strategy, why not start your own company and work on a solution yourself? I'm busy makign other ends of this project happen. |

CEV to be made commercially available
Which is why they should be buying launches, not developing new launch
vehicles. Yeah. Great. So... who has a commercially available heavy lift launch vehicle? 1. High launch costs Hop to it. 2. Cumbersome, low pressure EVA suits and gloves Centennial prize. 3. Better EVA tools Goes with 2. 4. Better designs for hardware intended for assembly or swap-out during an EVA (e.g. ISS assembly and Hubble servicing) One-use tech. 5. Refueling techniques for cryogenic fuels and oxidizers No plans yet for orbital refueling, and you've already pooh-poohed the concept. 6. Automated rendezvous and docking (useful for commercial ISS resupply) Buy it from the Russians. 7. Inexpensive reentry and recovery techniques for large pieces of hardware (e.g. SSME's) Buy it from the Russians. NASA ought to work on enabling technologies and techniques to open up space They did that in the '60's. Job accomplished. Now it's time to *use* that tech for that purpose. |

I agree that the hardware itself isn't inherently limited to a single use -- as best one can tell, given how little detail exists -- but as currently conceived, that stage is 100% expendable. Demonstartor 2R tells us that cheap recovery systems for the SSME (and CMGs when shuttle stands down) are still "just around the corner". This is the kind of demonstrator I'd like to see NASA building and flying, but it's not yet a proven technology. Jeff -- Remove icky phrase from email address to get a valid address. |

CEV to be made commercially available
wrote in message oups.com... And beyond that, what specific things can you do, things that are actually worth doing, with Stick/CEV? Building a space-based civilization. If somebody else can come up with somethign else to do it with, great. The stick/CEV will be too expensive for that. If your goal is truly to build a space based civilization, then you'd better start by lowering the cost of launching anything into LEO. In other words, invest in the start-up companies who are attempting to do just that. NASA is decidedly uninterested in lowering launch costs, since the stick and the SDHLV don't look like they would do much of anything to lower launch costs, and even if they did, they would only lower launch costs for NASA.

No trimming is done. As you can see, when one hits the "reply" button while posting from Google groups, no such header is included in the first place. I just can't be bothered to spackle in a new header. And OM... if you don't know who I'm responding to in this message... it's time to take a break. |

There's your first chance to do something. Get title transferred once the stage is abandoned. NASA doesn't officially abandon anything in space, so it's still government property. I'm sure they'd be upset if someone else started messing with their government property without their permission. Just ask Gus Grissom's family. They'll tell you what happens when NASA claims something is still their property. Resorting to name calling in a debate is always telling. So is the whining I'm seeing so often. Don;t like being called a whiner? Stop whining. Come up with somethign productive. I am. If CEV must go forward, I'm all for NASA using commercial launch vehicles to put it into LEO. In fact, I'm all for NASA using commercial launch vehicles for all programs, except for experimental vehicles of course. I'm also for NASA doing research into technologies and techniques that will open up space. I think they could do a lot more in the area of space suits than they've been doing in the past. I'm just being realistic. No, you're being defeatist. History backs me up. The glory days of Apollo funding will not return to NASA. The budget cutting started before the first moon landing even took place. It's the current NASA administrator who seems oblivious to this fact, just as Admiral Dick Truly appeared to be. But if you're so convinced this is a viable strategy, why not start your own company and work on a solution yourself? I'm busy makign other ends of this project happen. Glad to hear it. I'm busy working on FEA software. It's a useful thing to use if you're designing aerospace hardware. Aerospace is one of our bigger markets. All those structures and dynamics classes I took to get my Aerospace Engineering degree come in handy when working on this sort of software.
