There is No Santa Claus; Is There an Enterprise?

Saturday, January 30th, 2010

For months we’ve been waiting to hear what the Obama administration response would be to the Augustine Commission report on the future of NASA’s manned space flight program. Now it looks as if we have our answer, and it ain’t pretty.

The Augustine Commission outlined four possible directions for NASA. The last two were called “Flexible Path” and “Moon First.” The first two could be called “Moon Never” (though the report used different names). The commission further argued that in order to have a human space program that our country could be proud of, NASA’s budget would have to be augmented by about $3 billion per year.

As reported here and here and many other places, it looks as if President Obama has now placed his bets on the more ambitious of the two versions of “Moon Never.” Here is what I wrote about this option in my post from September:

Moon Never, ISS on Life Support. Slightly more palatable, this option also abandons hope for sending humans beyond low Earth orbit, but it at least acknowledges that it would be a disgrace to build a space station for 25 years, operate it for 5 years, and then torpedo it. The Augustine committee said that we can keep the ISS going to 2020 by developing a smaller heavy-launch rocket and relying on commercial companies to generate cheaper alternatives for launching humans into orbit.

This pretty much describes what I have read about the proposal Obama is going to send to Congress, although we can now paint in a few more details. There is some talk that the space budget will increase by $1 billion per year (not $3 billion per year). In early January, the word was that this money was going to go to NASA but now looks as if it might go in part toward incentives for private companies to build launch solutions. Obama is definitely scuttling the Constellation program and its associated rocket, the Ares I-X. This is a bridge-burning move. Even if we changed our minds and wanted to send astronauts to the moon by 2020, or even the mid-2020s, without Constellation we wouldn’t have the hardware to get them there.

Of course I am disappointed by this decision. However, it was not the least bit surprising. In today’s economy, with talk of a budget freeze on discretionary spending, where was Obama going to find $3 billion? I consider some of the online criticism of his decision to be disingenuous; I suspect that many of his critics would have jumped on him, perhaps even harder, if he had chosen to ask Congress for another $3 billion per year for NASA.

I’m disappointed that Obama didn’t take more seriously the commission’s finding that NASA needed this money to have any kind of credible manned flight program. It wasn’t really a choice between $18 billion and $21 billion. It was a choice between $18 billion flushed down the toilet, or $21 billion producing tangible results.

I’m disappointed also that there was no acknowledgement of the fact that, after the discoveries this fall concerning lunar water, the moon is actually an interesting destination again. Even if we concede that short-term financial considerations prevent us from having a viable human spaceflight program for a few years, a leader who was truly committed to space would outline a long-term strategy and a rationale that would include sustainable presence in space as its #1 objective. The best arguments I have seen in that direction are the ones on Paul Spudis’s blog. When you make that the rationale, the moon becomes a required destination, not an optional one.

However, I do see some reason for optimism in Obama’s decision, bleak as it may seem. It really does mark a break with the past. Gone is the pretense that NASA can do everything. Until now, there was always the hope that there was a Santa Claus, that the U.S. government or taxpayers would somehow step in and make NASA’s wishes come true. It’s possible that this was in some way holding back the efforts of private companies and investors to think creatively about what they could accomplish in space.

Now, there is no other game in town. We will only get as far in space as international partners and private companies, such as SpaceX, can take us. Lovers of free enterprise should be delighted; this is a chance to show that entrepreneurs can be better at “the vision thing” than presidents. For the near future, it seems, we are hitching our wagon to a starship named Enterprise.

I personally have some doubts. I’m not sure that space exploration companies are ready to walk on their own two feet. But we are going to find out, one way or the other.

LEAG Conference, part 2

Thursday, November 26th, 2009

 

While the LEAG meeting in Houston last week featured lots of exciting new results from LCROSS and LRO, it also provided an opportunity for discussion about the future of lunar exploration, human spaceflight, and NASA. The main theme of the meeting was sustainability: If and when humans return to the moon, how do they do so in a sustainable way?

One point that everyone (as far as I could tell) agreed on is that the Apollo model is not sustainable. By “the Apollo model” I mean what the lunar scientists like to call “sorties.” You build an enormous rocket, you take everything you need with you, you leave all of your junk there and you never use it again.

An alternative approach would be incremental or cumulative. You would probably start with several robotic precursor missions that would establish where your key resources are, and perform technology demos. Can we extract oxygen from lunar rocks? Can we extract water from lunar soils? Can we control lunar dust so that it doesn’t get into everything and cause all of our machines to break down? Can we safeguard astronauts from radiation?

If we find satisfactory answers to these questions, then we can build a base on the moon, although another possibility would be a base at the L1 point (or Lagrange point) where Earth’s gravity and the moon’s gravity cancel each other out. The things that you need to bring from Earth are brought a little bit at a time, somewhat like the way that we built the International Space Station. You don’t just go there, use your stuff once, and leave it. You need to re-use as much as you can. And finally, if there is anything that you can produce onsite, you do it. That primarily means (at this stage of the discussion) water, atmosphere, food, and propellant.

What I’ve just said may seem obvious, but it was surprisingly non-obvious for a very long time. Those of us who lived through the Apollo era were very surprised when the trips to the moon stopped. A lot has been written about the possible reasons: the public’s apathy, the Cold War politics that went into the moon race, the Vietnam War that sapped the American budget, etc. But maybe it had to happen. The whole approach was unsustainable.

Even now, many people still want to reproduce the Apollo model as we prepare for missions to Mars. This was the chief criticism that I heard of the Augustine Commission report. The “Flexible Path” option, many people felt, was just “Apollo on steroids,” traveling to more places with one-shot missions instead of building up the infrastructure for a sustainable presence in space.

I suppose I should name some names here. Paul Spudis is an especially passionate advocate of the idea that we must think about sustainability when we return to space. I wish I could just copy his whole presentation here, but that would not be very original. He said, “The goal is not to excite the public. The public must see the value in lunar exploration, which is different from making it exciting.” He took issue with the Augustine Commission’s conclusion that the ultimate destination (their words) is Mars. “The goal of returning to the moon is to become a spacefaring species,” he said. I think this is a great mission statement. Mars is not the ultimate goal; the ultimate is to be able to go wherever we want. Spudis would build up that capability on the moon.

Also, Igor Mitrofanov gave a perspective from the Russian space agency: “We will support missions to the moon if we will go there forever. Then we will participate as a nation.” He compared the moon to a new continent: “The first explorers looked for a place for a settlement, a bay, a harbor,” he said. Obviously he is arguing for a base approach rather than a sortie approach.

Many participants in the meeting said that sustainability would have to mean economic viability. Paul Spudis, as usual, formulated the question nicely, by listing three stages of lunar exploration: Arrive, Survive, Thrive. So far we have shown that we can Arrive. The next step is Survival — showing that we can stay for a long time on the moon — but ultimately the point of the whole exercise is to Thrive.

Both Spudis and Bob Wegeng, of the Pacific Northwest National Laboratory, drew analogies with the development of railroads in the 19th century. I went to lunch with Wegeng, who exposited at length about the railroads and told me some things that I did not know before. In school (in the U.S., at least), we all hear about the golden spike that completed the first transcontinental railroad in 1869. It’s part of our national mythology, just as much as the moon landing 100 years later. But that railroad went bankrupt several times, in spite of all of its government support!

The first economically successful transcontinental railroad, according to Wegeng, was the Great Northern Railway, built by James Jerome Hill. Wikipedia says it  was ”the first transcontinental built without public money and … one of the few transcontinental railroads not to go bankrupt.” Hill built up the Great Northern’s customer base by selling homesteads to farmers along the railroad route and even building industrial plants that would be served by his railroad.

If we want to learn from this example, it suggests that we will Thrive on the moon when a mega-corporation comes along, led by one person with vision, which does not just focus on the transportation technology but constructs a whole econosphere on the moon.

Who could that mega-corporation be? Not the current aerospace companies; they are too much like the government-backed railroads that failed. What about Google? I don’t know. It seems a little bit outside of their skill set, but they do have the vision. All things considered, the vision is probably more important than the skills or the capital, which can always be acquired on the way.

Anyway, getting back to the LEAG meeting, the one presentation that really looked at the moon from an economic point of view was by Brad Blair, a mining engineer who also works with the Canadian Space Agency. His paper was actually out of date — he presented an economic analysis of investing in the moon that he published back in 2002 or 2003. He analyzed five different scenarios, and in the last, ridiculously optimistic scenario he showed a possible return on investment in the range of $3 to $4 billion. I think the importance of his study lies not so much in the specific numbers or conclusions but in the methodology. I think his work needs to be updated for the decade of the 2010s. The discussion of lunar exploration has been completely dominated so far by scientists and engineers, but at some point some economists need to get involved.

Finally, in the discussion of sustainability, there were some interesting points made about public opinion. Spudis calls it the “50-50-50 problem”: public support for NASA has hovered around 50 percent for and 50 percent against for 50 years. And that includes the supposed heyday of NASA when we were racing to beat the Russians to the moon. Even back then, there were a lot of people who didn’t see the point, and argued that the money would be better spent solving problems on Earth. Public support for NASA has never been significantly more than 60 percent or less than 40 percent.

Spudis’ point was that if our justification for exploring space is “inspiring the public,” then we will never succeed. We need to go beyond inspiration to providing economic value.

At the same time, someone (I’m not sure who) pointed out from the audience that 50 percent support is not really a bad thing. Politicians are glad to have 50 percent, because it means they can be re-elected. Popular support for a lot of our public institutions runs a good deal lower than 50 percent. So instead of asking what NASA is doing wrong, perhaps we should advertise the fact that they are doing something right. Message to politicians: If you invest money in NASA, about half of the population will support you, as they have now for half a century.

The big unknown, at this moment, is whether any politicians are listening … especially the ones that matter, who live at 1600 Pennsylvania Avenue.

LEAG Conference, part 1

Thursday, November 19th, 2009

 

I’m back from the Lunar Exploration Analysis Group (LEAG) meeting in Houston, which ran from Monday through Wednesday this week. There was plenty of talk about LCROSS, which one member of the LCROSS science team calls “the little mission that did,” and also lots of discussion about the future of lunar exploration. The big theme of the meeting was sustainability: How do we go back to the moon in such a way that we can keep on going there indefinitely? Many, though not all, of the participants interpreted that question to mean: How can we make the moon economically viable? Of course, the LCROSS mission has a great deal to say about that.

Of course, the talk I looked forward to the most was by Tony Colaprete, the principal investigator for LCROSS. He gave only a few more scraps of information beyond what was reported in the news conference last Friday, but nevertheless I felt that the scraps fit together into an interesting story, which I wrote for the New Scientist website. You can find it here. I concentrated on the discovery of other volatiles besides water, because that was clearly what most interested the people I talked with.

I had to do a little soul-searching, because I go a little farther in the article than Colaprete would go in saying where the water and volatiles probably came from. But isn’t that my job as a journalist? If the experts are pretty sure about piece A, and they are pretty sure about piece B, and if there is only one way that piece A and piece B fit together and everybody knows it, shouldn’t I tell the public about that? Or do I have to wait until, ta-dah!, they hold a press conference and say they are ready to draw conclusion C?

Anyway, there were lots of other interesting and fun things at the meeting. For my blog I will concentrate on personal impressions rather than scientific news.

First, one thing I really loved about this meeting was how much joking and camaraderie there was. I don’t know whether it’s because it is a small enough community that everybody knows each other, or because certain people who are leaders in the community set the tone with their irreverence, or whether it’s just because everyone was in high spirits over the LRO and LCROSS results (and let’s not forget the Chandrayaan-1 results before that). Or maybe it’s just because geologists and planetary scientists are by nature goofy people.

Anyway, the big running joke at the meeting was Larry Taylor’s shorts. After the LCROSS press conference, he was quoted by the New York Times saying that he would have to “eat his shorts.” He was one of the scientists during the Apollo days who came to the conclusion — with good cause, I might add — that the moon rocks were “bone dry” and did not have a scrap of water. He told me that his grandfather used to say that he would “eat his shorts” if he were proved wrong, and so Larry told the newspaper reporter that he would have to eat his shorts now that water had been found in abundance. He had no expectation that this quote would be featured prominently in the Publication of Record. But then he got about 50 e-mails the next day asking if he would have a side of fries with the shorts, and what else he wanted to eat along with them. At the meeting several speakers ribbed him about this, and he finally said that he would eat them if they were served with a bottle of Guinness. Well, with unbelievable alacrity, a four-pack of Guinness beer materialized at the front of the lecture hall! I’m afraid I am not sure whether he eventually made good on his promise (I rather doubt it), but it shows how much fun people had at this meeting.

One of my favorite moments from the meeting was listening to a conversation between Wendell Mendell, another scientist who has been around since the glory days of NASA in the early 1970s, and Igor Mitrofanov, who is sort of his Russian equivalent. They swapped stories about the beginning of the Space Age. Mitrofanov described how when Sergei Korolev wanted to launch the first Russian satellite, he went to the Academy of Sciences, who of course loaded it down with more and more things that they wanted the satellite to do. It looked as if it would take forever, and Korolev was worried that the Americans would launch a satellite first. So he went to Khrushchev, the leader of the Soviet Union, and asked if he could launch a satellite that would just go beep beep beep. Khrushchev said sure, and Sputnik was born. Khruschchev didn’t think much of it, but when Sputnik flew in October 1957 and he saw how panicked the Americans were, he called Korolev back into his office and said, “I want another satellite by November!” (The over-complicated Academy of Sciences satellite did finally get launched, Mitrofanov said, but it was their third satellite.)

Mendell said that President Eisenhower was actually glad to have the Russians launch the first satellite … until he saw the furor that it caused. He wanted to be able to fly satellites over Russia to take spy pictures, because the U-2 airplanes that were doing this job were at risk of being shot down. If the Russians launched the first satellite, they couldn’t very well complain when the Americans launched one of their own. Nice plan, until everyone in the U.S. got hysterical about Sputnik, and the U.S.’s first attempt at a satellite launch blew up.

I guess these stories are probably pretty well known, at least the U.S. side, but I loved the idea of these two scientists, once separated by an Iron Curtain, being able to talk and laugh about these things.

More meeting thoughts and recollections in my next post …
