NASA, Congress Reach Accord On Commercial Crew Program 137
MarkWhittington writes "NASA and Congress have reached a deal on how to proceed with the commercial crew program that provides government subsidies to pay for the development of private spacecraft. NASA will select two competitors from the current four — SpaceX, Boeing, Blue Origin and Sierra Nevada. A third competitor will be picked for partial funding as a fallback in case both of the main competing companies run into difficulties developing a spacecraft on time and on budget."

The sad thing is that Sierra Nevada is in some ways doing more to help drop the cost of going into orbit than almost anybody else around. The Dream Chaser [wikipedia.org] spacecraft is really an amazing vehicle that is just beginning to reach a point of getting a payoff, which the early flight trials going on.
If they get cut, I hope that the investors in Sierra Nevada (and apparently Richard Branson of Virgin Galactic fame is one of them) continue to press forward without NASA funding.
They really don't deserve to be cut, at least so far as the investment being made by NASA into this company will likely produce some impressive long-term results. It is mainly sad that a jerk of a congressman who doesn't like these programs (COTS and CCDev) instead wants to dump 10x the amount of money on a fiscal black hole that will never fly (namely the SLS... aka the "Senate Launch System").
This move to reduce the options for CCDev is not going to save much money, and in fact it will set back commercial spaceflight by several years if not a full decade.

What is your logic here? You think it costs signifcantly less to turn Dream Chaser around than a Dragon Capsule? It looks an awful lot like a Space Shuttle to me for that.
The two who seem to be doing a lot for bringing the price down would be Blue Origin (who are banking on a seemingly unlikely SSTO), and SpaceX with their Resuable Powered Decent stages (which also seem pretty far away at this point). It takes a 130 million Atlas V to put a Dream Chaser into orbit last time I looked, where as the Dragon only needs a 60 million dollar Falcon 9. Although Dream Chaser *could* probably fit on a Falcon 9 and in either case you are looking at additional costs on top of the basic launcher.

In other words, NASA badly overspent on a first generation reusable. If the Space Shuttle had been able to carry a couple of people and a little payload, it'd have fit quite nicely into NASA's existing ( and for the foreseeable future) budget. Instead, they built the successor to the Saturn V. It sucked the oxygen out of the room for any other large space projects that didn't involve the Shuttle and contributed to its survival in some way.

I don't think it's that clear cut. As I mentioned before, the problems were overambition and budget cuts during the development process that made everything worse.
The overambition is actually quite understandable. Think of what we had gone from, at the start of the 1960s to the Apollo moon landings. This incredible pace of accomplishment was driving people's sci-fi dreams of the future wild, even people in high places. The notion was that, clearly, we're about to become a spacefaring race in a major way, we need a vehicle to haul people and tons of cargo with a rapid launch rate turnaround; that's where the inception of the concept came from. Of course, that was not to happen, and not only due to the fault of the shuttle program.
If the overambition itself wouldn't have doomed the goal of affordable reusable spaceflight, the budget cuts in development (brought about in no small part due to the Vietnam War) certainly did. The sacrifices made in development to accommodate them pretty much ensured that it would not be a reliable, affordable system. Turning to the air force for funding meant adding crossrange capability and even greater cargo capability. Disastrous. The lower level of funding meant less system reuse and higher maintenance on the systems that were to be reused. For example, the early shuttle designs called for a titanium frame which could run hot, instead of the current (cheaper) aluminum frame which can't. Letting the frame get hotter means you can use a simpler, and thus easier to maintain, TPS. Not to mention safer; the Columbia disaster couldn't have happened and there wouldn't be nearly as much metal fatigue concerns.
Again, hindsight is always 20-20, but it's easy to see how the problems came about from overambition and then huge budget cuts in development. And I don't think calling it a jobs program, at least initially, is totally fair. Unlike Ares, which is "let's use as much shuttle hardware as we can to keep the plants open and keep developing it even when there's no longer a niche for it", the Shuttle wasn't heavily based on Saturn hardware. Now, what I think clearly became a jobs program and takes no hindsight to see is that when the Shuttle program went down the tubes, and it clearly had failed at its nominal goal of affordable reusable spaceflight, of not only keeping it running but keeping it as the workhorse of the US spaceflight fleet.

The problem with your interpretation is that: a) The budget cuts were well known from about 1968. The design should have been scaled down from the start.

Orion really does a lousy job for areas beyond LEO though. While it has just under 2x the usable internal volume that the Apollo spacecraft used, that won't exactly be something to brag about. Perhaps reasonable for a trip to the Moon, but I don't see how it will possibly be used on a trip to an asteroid much less Mars. The "habitable volume" of the Orion is very much comparable to the internal volume of the Dragon. I just don't see how astronauts are going to be expected to hang out in that kind of volume for weeks and months.
What makes the Orion useful for beyond LEO is mainly that it has its own solar energy generator array, and that the heat shield is being designed to perform re-entry of a free-return trajectory from the Moon and a similar return flight coming from Mars. Then again the Dragon capsule is being designed with those same parameters as well.

Furthermore, do you even have a clue what part of the CCDev program that Blue Origin is even doing, what their spacecraft actually is supposed to look like, or how it is going to get into orbit much less return to the Earth? If you did, you wouldn't have made such a stupid statement presuming something that wasn't even true.
*Hint* -- Blue Origin proposed to use the Lockheed-Martin Atlas V for the launch of its spacecraft under CCDev. They aren't even planning on flying their own hardware for the first stage or two.
Without tax payer dollars, from the beginning, Boeing, United Airlines, McDonnell Douglass, Lockheed Martin, etc., never exists. These ``leave it to private enterprise'' stalwarts seem to ignore history. Really big ideas require national support. Unless you have a company with the funding like Apple willing to fund billions nothing will evolve in space without the US Government.

Again I ask how you know so much about what Blue Origin isn't doing? I can name a few things they are doing, but due to the fact they are so tight lipped it is hard to say what they aren't doing because you can't prove a negative action.
In the case of SpaceX, you would know what they are not doing because if there was anything they were doing it would have been discussed a long time ago. It is thus easy to say that SpaceX isn't building inflatable orbital habitats because if they were it would be somethin

I have to disagree with you on SSTO being nonsense - only a small percentage of the cost of an orbital launch is the unavoidable fuel costs, much of the rest is in ground control and and the fact that we're basically throwing away everything except for the orbital capsule with every launch. That made great sense during the cold war when the space program was basically PR campaign piggybacking on ICBM technology to reach orbit - and an ICBM is pretty much by definition a single-shot vehicle and requires gro

New Sheperd in all regards hits me as pure naivete. For example, using HTP as an oxidizer. I'm well familiar with the logic here. "Oh, sure, it's got less ISP than LOX, but it's SIMPLER! And ISP isn't everything! We'll go simple and cheap, and get a simple, cheap craft!"
And that logic is wrong.
First off, the lesser issue: ISP may not be everything, but it's huge. The scaling factor for having bad ISP is pretty massive, and your other costs will add up quickly as your craft balloons, everything from your transport costs to your launch liability. People who just discount it like that do a big disservice to themselves.
But the bigger issue: HTP is *not* simpler than LOX. It's a giant pain in the arse. It's explosive, which requires that you have sterile, defect-free tanks and systems with very specific materials requirements and purity constantly maintained. Its explosivity can be greatly reduced by the presence of stabilizers, but therein lies the other problem: the more stable you make it, the less reactive it becomes, and if you're using any sort of catalyst pack (which themselves are full of problems), you tend to clog it. Peroxide vapors from even stabilized HTP are explosive. Stored HTP can become less stable over time, and leaks can be catastrophic (as many people, perhaps most famously in recent years the crew of the Kursk, have learned). Heat can set it off. It's difficult and dangerous to concentrate in terms of oxidizer production. It's illegal to ship in tanker trucks due to its hazardous nature. Etc.
People think about household H2O2 solutions and just picture a more powerful version of that. That is not what HTP is like. The Germans and later the US went with HTP a lot early in their rocketry programs. The fact that its usage became greatly curtailed over time should speak volumes.
Basically, HTP is just reinventing a bad wheel. There's one little explored fuel combination that I'd like to see more focus on, personally: LOX/Propane. Propane is of course widely available, cheap, and easy to transport. It's higher ISP than RP1 (LOX/RP1 being a common propellant combination), but the downside when you first look at it in a table is it's much lower density. BUT, at the same temperature as your LOX - aka, they can share a common bulkhead without insulative separation, reducing system mass -- it's actually quite dense. LOX/Propane is also easier to vaporize and ignite.

Interesting points, I'll admit it's been a long time since I paid much attention to the details of launch systems, too many other interesting fields to keep track of. It does sound like HTP might prove to be an... interesting choice of oxidant, especially for a reusable vehicle where systems will inevitably develop stress flaws
One observation about propane though - unless the Propane has a notably lower total volume than the LOX it would seem a shared bulkhead will significantly *increase* the amount of i

The largest current problem the HTP is simply getting permission from the Department of Homeland Security to even let you ship it at all, where refineries which make the stuff generally won't ship to you unless you are already using it in large industrial scale quantities. That really stinks if you are using for R&D purposes or something like a small start-up company.
Armadillo Aerospace spent a whole bunch of effort on the stuff, and John Carmack even sent out a general request on several mailing lists

I'd like to point out that Space X did first prove they're capable of real life feats with Musk's own money. Yes the latest developments and the docking with ISS has been co-funded (or mostly funded) by NASA and they'll pay them more for additional launches, but they're getting a real deal out of it as SpaceX is doing it way cheaper than any alternative and they actually deliver already today, not far fetched promises.
Re:Handout to the rich (Score:5, Insightful)
You forget the alternative. If the public funds the development of new rocket systems by NASA and keeps using them at a cost of 5x that of the private company, then after N launches the total cost for the public is higher than had they developed it in cooperation with a private enterprise that then operates the technology under contracts at a much lower cost. As an example, Falcon 9 of Space X has lift capacity of 10 tons for a cost of $56M. The Delta-IV rocket had 22 tons and $300M so the cost per kg is 3x higher. The Ariane 5 rocket by ESA has 21 ton lift to LEO and cost of $200M. The Atlas V (earlier one) had lift on 9t at a cost of $125M.
Now if Space X can pull off Falcon Heavy (the first launch is planned already in 2013) then the planned cost of 53t to LEO is $80-125M. That gives it a per kg cost of 5.8x less than Delta-IV, 4x less than Ariane 5 etc. And that's assuming the high end of the price range. It's also a rocket that can deliver cargo to trans-lunar-orbit or even to Mars (14t to Mars, 16t to trans lunar). Why the hell would we need an SLS with 50-130t capacity with an outrageous price tag when we can just launch two Falcon 9 heavy's for the same capacity and probably less than the equivalent launch cost and if need be assemble the final inter-plantery spacecraft in orbit...

They bet the company on the 4th launch and it worked and have been delivering cargo to LEO and now to ISS since.

The maiden flight of SLS is planned in 2017 while I'd assume the Falcon Heavy or it's successor might easily be providing the service in

I think a lot of this is indeed coming from the fact that SpaceX is operating like a startup.
