NASA's Commercial Crew Development program, or "CCDev", has been a resounding success - and that's why they're not doing it anymore.
Inspired by the earlier Commercial Orbital Transportation Services program, or "COTS", and funded by the American Recovery and Reinvestment Act of 2009 stimulus to the tune of $50M, CCDev came out swinging in 2010 with five US companies producing impressive results on what was essentially bonus pay to NASA. As such, it was no surprise when a further $270M was provided for the second round, or "CCDev2". This round is now coming to a close, with continuing achievement from US companies with minimal oversight from NASA. Also, a number of "unfunded" CCDev agreements have been made which receive only use of NASA facilities and expertise - they too have been successful.
With all this success, it might seem strange that NASA is dropping the CCDev program - but they are. They intend to move on to a "procurement" process where a number of companies will be required to submit designs, to be reviewed by NASA, with an eventually "down select" to one or possibly two approved providers for the next phase. The Commercial Crew Program, or "CCP", requested funding for the next five years is $850M/year or $4250M total, but at this time it appears unlikely that they will get more than $500M in the first year.
No, that's not a misprint. Here's a graph to hammer home the point.
Why the massive jump? The simple answer is given by acting program director Phil McAlister's comments at the 2011 International Symposium for Personal and Commercial Spaceflight - the commercial crew office has grown to 250 people, many of which are spending their days writing requirements and regulations and have been for "the last two years". In the near future, a number of these staff will be "embedded" into the companies doing their initial design work. This massive increase in oversight comes with a switch from Space Act Agreements - where NASA pays the partner only after agreed upon milestones have been met - to Federal Acquisition Regulation contracts. Although it is increasingly obvious that "partners" are becoming contractors, and NASA is taking control over the industry, McAlister continues to downplay the change, stating that it is "just rhetoric from people who don't want to engage in debate".
Well here's some debate. Fundamentally, the COTS and CCDev rounds were about partnership. NASA was not in control and this was a good thing - for the industry, for NASA and for the taxpayer. Yes, Space Act Agreements have been proven to work, but it's not just about that - it's about who has control in this relationship. Under the COTS/CCDev program, a partner could say no. They could say they weren't interested in pursuing a proposed milestone and NASA had to negotiate. The pay-on-performance standard encouraged partners to only take on milestones they knew they could achieve and, with good faith, NASA had clearly defined. Those milestones represented where the goals of the partner matched the goals of NASA - which many don't seem to understand are necessarily different.
During a congressional testimony today, where Elon Musk was a witness for the first time (see this summary in PopMech), Congressman George Miller (D) asked two questions which insisted that eventually NASA will have just the one provider for commercial crew. Later, Congresswoman Donna Edwards (D) expressed concern that NASA is creating a US monopoly on commercial crew. Setting aside that these people are supposed to be telling NASA what to do, not meekly asking for a forecast of the future, the NASA representative - William Gerstenmaier - essentially agreed with the assessment, stating a lack of funding to support two providers.
Oh, did I not mention that? Yes, NASA thinks nearly five billion dollars isn't sufficient to get commercial crew providers to a point where they can start actually paying them for seats. How much exactly they're going to pay them for seats is anyone's guess. SpaceX will happily tell you that they can do $20M/seat, but that assumes 28 seats per year. Which could mean anything because NASA can't actually tell you how many seats they want. NASA at least wants the price of seats on US commercial crew providers to be below the price of seats on Soyuz, but they seem to have no clue anymore why that is. As such, this has encouraged a number of hilarious Congress-does-math moments where the representative will add together the cost of development, price per seat by estimated number of seats, get a number which is bigger than just continuing to buy seats from the Russians and wonder how this is going to save NASA money. Hint: it's not. That's not the goal. The goal is to kickstart the industry by having NASA as an anchor tenant. The only reason to care about the Soyuz price at all is to ensure the US commercial crew providers are competitive in the international market. This should be obvious but NASA/Congress are stocked with morons.
Here's a prediction.. you heard it here first.. that whole lower-than-Soyuz-price thing will go away real soon. I think this will not be the last way NASA breaks the former-partners making them uncompetitive. Ultimately, the product that NASA wants - the mythical space transportation system that will keep the precious astronauts safe on their purposeless jaunts to "occupy" the ISS, maintaining international relations and supervising ants sorting tiny screws in space - is incompatible with actual productive use of human spaceflight. When the commercial markets fail to materialize, the government can say "we told you so!" and essentially nationalize the industry, as they did with launch vehicles.
Briefly, how was it ever supposed to work? The vision, for those who can remember it, was for NASA to simply buy tickets on commercial crew transportation providers. It was supposed that a promise to buy some number of seats per year would have been enough to encourage private development of the vehicles. This of course was naive, as a promise from NASA is about as bankable as a promise from Congress - that is, worthless. So instead, some money was thrown over the wall with a minimum amount of whatcha-gunna-use-it-for? The hope being that private investment would come to the table. This worked! So the sensible next step is to keep doing the thing that works.
Part II: The Market
What would happen if NASA continued to encourage the industry to develop, instead of embarking on a premature "procurement" process for their own piddling little needs? The answer is glorious: multiple commercial crew transportation providers racing to be the first available to offer seats. Actual price competition and ongoing innovation. This would open new markets and the virtuous cycle would open up the entire frontier.
But... so many people can't remember this vision - if they ever knew it at all. We regularly hear the proud proclamation that the government is the only "market" for human spaceflight. Ok, maybe they're willing to grant that there's a market for a few "overly rich tourists", yes, they really use that word, and maybe there's some other countries that would like to have a space program but don't have the wherewithal to slap together their own big-rocket-and-capsule program, but that's just icing on the cake. Even the commercial crew transportation providers seem to be ignorant of the actual market which is out there waiting to be tapped. Even Elon Musk seems to be ignorant of the real market.. there, I said it. Talk of colonizing Mars someday is great, but that's not where the money is right now.
I can hear the space solar power people screaming from the balcony. They know the answer! And while I appreciate their enthusiasm, I think they're wrong. Someday, space solar power will be operational and human spaceflight to maintain those massive solar arrays will be necessary, but that day is not here. We should keep them firmly in mind and think about their needs when making decisions about on-orbit capabilities, but right now they're still on the ground.
No, the market I'm talking about is the one space market that has consistently made profits since the beginning of the space age. In 2005 PanAmSat launched the Galaxy 15 telecommunications satellite, its ownership was later transferred to Intelsat. In April of 2010 control was lost and the satellite starting drifting, causing significant hazard to other satellites. More importantly, the satellite was out of commission and losing money every day. An estimate of the loss of the satellite, was required for accounting purposes and a figure of around $4194M was given, or ~$400M per year for the expected remaining lifespan.
This gives us some idea of the acceptable price for a satellite "rescue" mission out to geostationary Earth orbit. It's hard to imagine NASA screwing up commercial crew so much that such a mission could be made unaffordable by US suppliers, but if seats are available on the Russian Soyuz - as they will be when NASA finally switches to commercial crew - the inability of US human spaceflight providers to beat the Soyuz price will suddenly become important.
Much more interesting, I think, is to consider the current SpaceX pricetag of a Falcon 9 / crew Dragon flight, upgraded to the Falcon Heavy, and before any of the price reductions promised by reusability.. let's say, $200M. At this price it is not inconceivable to imagine sending a crew out annually to service a number of satellites in a constellation. When we consider that routine maintenance has never been done on communication satellites, it becomes obvious that extended lifetimes can be achieved that would more than offset the cost.
In short, NASA isn't the market for human spaceflight, it isn't even the icing, it's the free frogurt - don't eat it.

This Is Why Space Settlement Is Important
It's the end of civilization.. or so some would have us believe. If they don't get their wish, they intend to take it.. by force. Humanity going into space isn't about leaving them behind, but wouldn't it be nice?
With my most humble apologies to Jeff Greason.
As a follow up I posted this over at kuro5hin.

EML1 Buildup
Today's space launch market is used to place satellites - commercial, scientific and military - into orbit, with the majority going to the geostationary orbit. In all such cases, the launch vehicle does not perform the final maneuver to circularize the orbit. The satellite is dropped off and circularizes its own orbit using on-board propellant. This is a significant delta-v change of about 1.6 km/s, and the remaining fuel is used to maintain the orbit, usually for 25 years or more.
Launch to Geostationary Transfer Orbit, circularize using on-board propellant. This is the standard model for how satellites are deployed into space. It is a mature process which has served us well for decades. However, when planning an exploration architecture, it has always been treated as irrelevant.
Here is a list of some current (and one near future) launch vehicles, their listed throw mass to GTO and the calculated mass that can be placed into the first Earth-Moon Lagrange point using a 312 second specific impulse storable propellant thruster (GTO to EML1 delta-v is 1.27 km/s).
What should be obvious is that there is quite a healthy international stable of launch vehicle providers, and they're all geared up for sending payloads to GTO. What is perhaps not obvious is that by going from GTO to EML1 I am seriously cheating myself. I don't mind because throwing to a lunar transfer orbit is something all of these vehicles can also do and, in all cases, the subsequent transfer to EML1 will be less than a transfer from GTO. As such, we can accept the numbers above as accurate, even if they are overly conservative.
So what does this mean? Suppose we want to land a payload on the surface of the Moon. One option is to simply pick the biggest one of these rockets and fly it directly to lunar orbit and start our descent. The total delta-v for such a mission is likely to be about 3.2 km/s, which means we can land a maximum of 6676 kg.
Suppose, instead, we fly to EML1 and pick up fuel. The table above indicates we can put a maximum of 12546 kg to EML1, and the delta-v from EML1 to the lunar surface is 2.52 km/s, so we need 16043 kg of fuel to make the trip. Because we're using storable propellants, this can be delivered over a long time using whichever provider offers the best price, or over a short time by engaging as many providers as become available.
Although this is just a rough analysis, it shows that we can land twice as big payloads by building up EML1 with propellant, without the need for any new launch vehicles, new technologies or even new ways of doing business, and we could start doing it right now.

Dreaming About NASA Mismanagement
There's so many things packed up in this clip. For a start, the House isn't trying to cut the James Web Space Telescope (JWST) because "we don't have the money" or to save money or for any budgetary reason what-so-ever. The House is trying to cut JWST because the Government Accountability Office reported that NASA, and the contractor, have been mismanaging this program. They reported this three different times and required reports on what NASA was going to do about it - NASA didn't provide those reports. The House even said that the reason they were looking to cut JWST was to send a message that ignoring oversight will not be tolerated.
Does that mean the JWST isn't important? No.. no-one is saying that. Everyone agrees that JWST is important and that it will give results of significant scientific discoveries should it ever be completed and launched.. but when will that be? Within a two week period - after the House suggested cutting the budget - the program managers said 2020 or 2018 - neither answer was given in writing. Both answers were contingent upon an increase in their budget.. there's a word we use for declining to increase the budget of mismanaged projects: smart.
So is that the end of JWST? In the minds of NASA-can-do-no-wrong advocates, yes. They immediately declare that you're just not throwing enough money at the problem. It goes something like this: Oh, Hubble was massively overbudget and even broken when it launched. If we hadn't thrown more money at the problem we wouldn't even know about [insert discovery of cosmic significance here].
Meanwhile, the cosmologists are going around saying that the JWST is "essentially complete" or that "we've already built it". This isn't just the sulk cost fallacy, they actually think the JWST is ready and Congress is pulling the rug out from under them. This isn't the case at all, and not even NASA is making this claim. I've been suggesting that, if this were true, people who really want to see JWST fly should be calling for a firm fixed price contract - where the contractor covers the cost overruns, and NASA has less opportunity to screw things up - which has been proven time and time again to result in projects that are completed on-time and under budget.
Failing to mention any of this, Tyson then goes off into one of his standard rants. Oh, we've stopped dreaming. We don't look up. We've turned inwards. Can you imagine why? Hint: it has something to do with NASA mismanagement.
Back in the 1960s people dreamed of going to the Moon. Guess what? NASA went to the Moon. Was NASA not grossly mismanaged back then too? Of course they were, but they were given the mandate to "waste anything but time" and that is one thing government does well: waste.
What did people dream about in the 1970s? Space settlement. These dreams became plans, that wasn't the problem. All the engineering analysis at the time indicated that NASA could do it, so what happened? The plans called for cheap access to space and that requires the opposite of government: efficiency.
Instead, NASA became a government agency focused on "international cooperation", with first the Shuttle-Mir program and later the International Space Station, and while I'm sure there was plenty of people out there dreaming about more cooperation between nations, it had little to do with looking up.

We Need Technology Development
It seems pretty obvious that we don't currently have the technology to become a spacefaring civilization. Certainly there is stuff in space we could be doing using existing technology, and with great expense, but to really begin the human utilization and colonization of space we need a large variety of technological innovations.
Jon Goff gave a great list of short term technologies that need to be developed before we can really consider society to be spacefaring.
This should be the start of the story.

How COTS-D Was Killed
Lest we forget, under Mike Griffin NASA awarded to SpaceX an option in their Commercial Orbital Transportation Services contract to develop a crew transport capability. The Space Act Agreement looked like this:
As with all the COTS milestones, SpaceX would not have received these payments until the milestone was completed. The finance milestones were required to demonstrate that SpaceX could fund and complete all the milestones without using the payments from NASA as "seed money".
The COTS-D option was never activated. You may even hear some people at NASA say that it was never "funded", this is wrong. The final nail in the coffin of COTS-D came in the form of an intriguing exchange between Sen. Bill Nelson and then acting NASA Administrator Chris Scolese. Here's the relevant part of the long transcript.
And that was the last opportunity for COTS-D. Had NASA obeyed the law and provided the $150M that was allocated in the FY09 budget, SpaceX could have started COTS-D and completed the first seven milestones. When the $150M in stimulus money came in SpaceX would have been on much better footing to claim part of it. Instead, Sen Shelby was able to divert $100M to the development of Ares I, a vehicle that was later scheduled to be cancelled prompting him to insert language into law prohibiting NASA from doing that. Of the remaining $50M, SpaceX received none.
The official position of NASA seems to be that the CCDev program has replaced COTS-D. SpaceX has put in a bid for the new round, which NASA has been prohibited from starting due to the failure of Congress to pass a budget for FY11. Should SpaceX be successful, they intend to start work on the launch abort system which will also allow the Dragon spacecraft to land vertically on land. While I have been assured that the CCDev program will be "milestone based" like COTS, I still have my doubts that it will capture the simplicity of the COTS-D option.
| Milestone | Payment |
|---|---|
| Project Management Plan Review and Crew Demo 1 System Requirements Review | $27,420,000 |
| Financing D1 | $10,000,000 |
| Crew Demo 1 System Preliminary Design Review | $22,420,000 |

The COTS-D option was never activated. You may even hear some people at NASA say that it was never "funded", this is wrong. The final nail in the coffin of COTS-D came in the form of an intriguing exchange between Sen. Bill Nelson and then acting NASA Administrator Chris Scolese. Here's the relevant part of the long transcript.
Senator Nelson. In last year's authorization bill, there was guidance to NASA about COTS-D Space Act agreements to develop a U.S. commercial alternative to Soyuz. We authorized $150 million in funding for COTS-D. I noticed that you are
putting $150 million of stimulus funds toward the Commercial Crew and Cargo program, but not actually initiating COTS-D agreements. Why are you not initiating these Space Act agreements?
Mr. Scolese. Well, we are working the commercial program as you defined. There was cargo on it. We have those two contracts with SpaceX and Orbital to do cargo. We had one for COTS-D. I cannot recall a specific--$150 million to go on to COTS-D. We did this year in the stimulus identify $150 million to stimulate a commercial activity, and it is broken into two pieces: $70 million to go off and develop capabilities that any visiting vehicle would need, including commercial vehicles, and that includes developing the human space flight rating requirements, the requirements that you need to be certified for human space flight. As you well know, we build human spacecraft and design them so infrequently that we have to write those requirements down. So part of this is to make those available to everybody, make them understandable to everybody, and that will help not only the commercial providers broadly, but all of us. And then $80 million to stimulate activity for a commercial crew.
[recess for a vote]
Senator Nelson. I want to go back to the question that I had asked you earlier. You described the breakdown of how you intend to program $150 million for Commercial Crew and Cargo. Instead of putting the dollars into the various component pieces that would enable crew capability, would it not make more sense just to invest that in a milestone-based demonstration flight?
Mr. Scolese. We discussed that, and we believe that we need to take a measured approach to developing commercial crew. As you know, again it is a very difficult prospect to develop a crewed vehicle to carry crews safely to and from space, let alone rendezvous and dock with the Space Station. So we are working a measured development where we work progressively from developing the capability to get into space, to conduct the rendezvous and docking with the Space Station, to crew rescue, which can be done without having to worry about crew escape,
all the way up to carrying crew. That is the philosophy that we are working to achieve. To do that, we needed to do some things that broadly help the community that wants to do this, as I mentioned earlier, about developing clear and concise specs and standards so that we can safely put our crew on those vehicles. And further, I think you have seen the annual report of the Aerospace Safety Advisory Panel that had some questions about the detail of our human rating requirements. So that is all part of what we are trying to accomplish, and we believe that will get us a commercial crew capability quicker and safer than if we were to just go off and suggest that we fund a capability.
Senator Nelson. But that was not what the legislation said. The legislation said that $150 million was funding for COTS-D. In this case, you would not even have to pay until the COTS-D partner was able to successfully demonstrate that capability. Is that not right?
Mr. Scolese. It would be dependent upon how we structured it. Of course, we wanted to maximize competition for the vehicle. As you know, there is only one COTS-D provider.
Senator Nelson. Well, when I say "you," I am referring to NASA, and you were not the Acting Administrator at the time. This is an example of where NASA has not followed the legislation. Now, let me ask you this. Would $150 million be enough to demonstrate that capability?
Mr. Scolese. We would have to look at it, but I do not think so, sir.
Senator Nelson. Well, what do you think it would be?
Mr. Scolese. I would have to get back to you on that, but it would be several times that, I would expect, because recall, we have to develop not only the crew portion of it. We have to develop the life support systems, the launch escape systems, the recovery systems. All of those have to be developed and demonstrated, and $150 million does not seem enough to do that.
Senator Nelson. We had a unique opportunity, if NASA had listened and followed the law, we had a unique opportunity this year between the 2009 operating plan and the additional funds provided by the stimulus bill and the development of the 2010 budget to craft a COTS-D plan that would have funded the program at the level that the folks needed. That path was not pursued. NASA did not obey the law. Again, I am not saying it to you because you are the Acting Administrator since January 20, but I want to point this out that sometimes NASA does not want itself to be helped. We have got to get our act together.
And that was the last opportunity for COTS-D. Had NASA obeyed the law and provided the $150M that was allocated in the FY09 budget, SpaceX could have started COTS-D and completed the first seven milestones. When the $150M in stimulus money came in SpaceX would have been on much better footing to claim part of it.

Two Game Changing Technologies
The Gravity Loading Countermeasure Skinsuit (yes, that's Richard Garriott) and Mini-Magnetosphere Radiation Shielding are two technologies which, if successful, will change the way you think about space exploration and eventually even colonization. They address the two fundamental stumbling blocks of long term missions in space: the negative health affects of zero-g and radiation exposure.
Zero-G Skinsuits exert a force on the wearer's body which duplicates the loading on the skeleton that gravity usually provides. The expectation is that Skinsuits will reduce or eliminate the deleterious bone loss that astronauts currently experience in zero-g. So far, the prototypes have only been tested on parabolic flights, although they are similar to the Russian penguin suits which were used by cosmonauts on MIR (unfortunately with little to no reported results - as is typical of Russian space medicine).
Should Skinsuits turn out to be effective at eliminating bone loss, and possibly even have some positive effect on muscle loss, this finding will render other technologies aimed at addressing the problem less important. Specifically, solutions aimed at getting astronauts to Mars as quickly as possible will be less important. Artificial gravity generation for long trips or even for space colony designs will be less important too. Although there may still be a use for weak fluid settling variations on the theme, not having to produce an Earth-like gravity field is a much easier engineering problem.
MiniMags produce an electric field around a spacecraft that interacts with the interplanetary plasma to produce a charge separation, strengthening the field. When ionizing radiation hits the electric field it is deflected and so does not cause damage to the spacecraft or its occupants. It was widely believed that such a "magnetic shield" of solar radiation could not be achieved without superconducting magnets and large power sources - placing it firmly in the domain of science fiction. However, a number of observations of solar wind phenomena and subsequent ground experimentation has shown that only a small electric field is initially needed - the neutral interplanetary plasma will do the rest.
Should MiniMags turn out to be effective at protecting spacecraft and human occupants from ionizing radiation they will solve perhaps the biggest problem with long term human exploration of space, and eventual colonization. Previously, the only known way to deal with the radiation problem was to surround the crew with mass. Over the years, a number of creative techniques have been devised to have the mass serve double duty - for example, using propellant or consumables mass to shield the crew. Careful study of the available materials for shielding has led us to determine that high hydrogen content materials like polyethylene are best, suggesting that the interior of crew cabins should be lined in the stuff, and windows should be replaced with periscopes (because ionizing radiation only travels in straight lines and is not reflected by mirrors). All these design problems go away with an effective radiation shield.
At the time of writing, neither of these technologies is being adequately funded. While the NASA Technology Roadmaps currently identify "pressure garment" suits as a potential avenue for research, they place it in the EVA-suit category and seem to be unaware of Skinsuits. MiniMags are not identified in the technology roadmaps at all.. This is particularly egregious as not only can MiniMags be used as a radiation shield, but they can also be used for in-space propulsion. As such, they should appear in both TA06 and TA02. But never fear! I've informed the Aeronautics And Space Engineering Board of this oversight and I'm sure they'll get right on it ;)
