Mitt Romney’s Space Brain Trust

As others have pointed out, the presence of Mike Griffin on this apparently-hastily-assembled  list of Mitt Romney’s advisors on space policy is utterly appalling. But what of Gene Cernan, the “Last Man on the Moon”?

He doesn’t seem very confident in commercial space:

Do you have any hope for commercial space efforts, like Space X?

It has been the commercial space industry, under NASA’s leadership and guidance, that has allowed us to get to the moon and build a shuttle and everything that has happened in the last 50 years. To entirely turn it over without any oversight to the commercial sector, which is a word I question anyway, is going to take a long time. Some of these guys are highly qualified, but some are young entrepreneurs with a lot of money, and for them it’s kind of like a hobby. Not all of them. But some of them are making claims to get into space in five years for $10 billion, and even the Russians say it’s going to take twice as long if we put our eggs into that basket. I don’t have a lot of confidence in that end of the commercial space spectrum getting us back into orbit any time soon. I’d like to hear all these folks who call themselves commercial space tell me who their investors are. Tell me where their marketplace is. A commercial venture is supposed to use private money. And who are their users? Suppose we, NASA, have no need for their services. There’s no other marketplace for them. So is it really a commercial venture, or is it not? Is it a group of guys who have stars in their eyes and want to be a big space developer? I don’t know.

I don’t think they’ll come anywhere near accomplishing what they’ve said they can do. I said before Congress, and it’s still true today, they don’t yet know what they don’t know. We, if you’ll allow me to include myself with NASA, have been doing this for half a century. We have made mistakes. We’ve lost colleagues. Don’t you think we’ve learned from some of those mistakes? You bet your life we have. They have yet to learn from those mistakes. And I’m not willing as a taxpayer to sit here and pay them to make those mistakes before they can ever get where they think they can go. Now the good news side of this is there are some of the larger aerospace companies looking into getting into it, the Boeings, the Lockheed Martins, the ATKs, are now looking to compete in the commercial side of the business. That’s a little more encouraging. Those are the folks who have been working on everything we’ve done for the last 50 years. They know how it can be done.

Not encouraging at all. Would I still vote for Romney over Obama, knowing this? In a heartbeat. Putting out of office the corrupt and dangerously incompetent disaster currently in the White House would be worth the (manageable) risk of strangling the Obama space policy in the crib. Would we need to keep a sharp eye on a President Romney’s space policy to make sure Mike Griffin and others with Griffinian proclivities couldn’t pull the stake out of the heart of Constellation and resurrect his dream rocket at the expense of a non-NASA-dependent space industry? Absolutely. But when has there not been a need for space advocates to stand watch on space policy?

UPDATE: Interesting that Robert Crippen, another Romney space advisor, served as president of Thiokol Propulsion. 

Scott Pace [PDF] was head of program evaluations at NASA during the Griffin years, and at least as of last August Pace was promoting a return to the Ares I/Ares V architecture (as a better alternative to the SLS, believe it or not):

“Ironically, the budget pressures being put on the program right now would in my mind argue for returning to the previous plan,” Pace said, “which was launch and build Ares I first and build Ares V later.”

Ares I was the first and smaller of tworockets in the now-canceled Constellation program, which also included a Multipurpose Crew Vehicle (MPCV) that is being constructed. Ares I, which could have taken astronauts back to the moon, was being developed in Huntsville by many of the aerospace workers now facing layoffs.

For Pace, Ares has several positives. First, a lot of money and time have already been spent on it, and that work would feed into the larger rocket later.

“You build on the work that was already done,” Pace said of Ares I. “You can fly the MPCV. You have five-segment solid (rocket motors) that are already done. You have a use then on the upper stage for the J-2X engine, which is also in development.”

James P. Hogan

Not only did I not know until just now that he passed away a year and a half ago, I also didn’t know he went a little wacky in his later years.

What a pity. I was pretty fond of his earlier stuff - the Giants series was one of my favorites as a kid (I don’t believe in it, but I’m still a sucker for a good Velikovskian yarn), and Voyage From Yesteryear was one of my first real introductions to libertarian ideas, since I didn’t read any Heinlein until I was eighteen. And just this morning I was randomly thinking about the premise of The Genesis Machine.

An Annoying Feature of Non-Fiction Books

Introductions or prefaces which are longer than the book’s chapters.

I’ve been doing a lot of background reading lately as part of writing the sequel to In the Shadow of Ares, and this seems to afflict every book I’ve picked up. I’m slowly getting over the notion that I ought to read them before reading the book proper.

Indian Migrations and Space Settlement

I’m doing some reading in Indian history as part of my research for the sequel to In the Shadow of Ares. In John Keay’s India: A History, I came across this interesting passage in his discussion of the ‘epic age’ of the Mahabharata and Ramayana:

As for the retreat into exile, the other central theme in both epics, this is taken to indicate the process by which clan society resolved its conflicts and at the same time encroached ever deeper into the subcontinent. Eventually population pressures on land and other resources would encourage greater social specialisation and he assertion of a central authority, two of the prerequisites of a state. But during the first centuries of the first millennium BC, these same pressures seem merely to have encouraged a traditional solution whereby clans segmented and split away to explore new territories. [emphasis added]

In the context of the chapter, he is taking a common thread of the two epics (the exile in the wilderness of their respective protagonists) as a hint as to how the ?r?an colonists gradually spread to the east and south from the Indus Valley.

What struck me as interesting is that much the same thing could happen with space settlement, especially given some TBD mode of practical interstellar travel.

In the near term (say, the next 100 years), if efforts to commercialize space access pan out and we begin building colonies in space, on the Moon, and on Mars, we will have established a new “wilderness” in the sense Keay describes elsewhere in the chapter: an untamed space where danger may lurk away from the safety of established civilization, but where the freedom exists to build afresh. The process of settlement and ongoing development will due to resource and labor shortages limit the degree to which a central authority can be asserted, providing a breathing space for innovation between the continuously expanding frontier and the expanding boundary of civilization trailing behind it. Political or social conflicts unresolvable in the civilized regions can be defused through one or another party choosing to escape to the freedom of this breathing space or the wilderness beyond, thereby pushing the frontier further outward — versus being kept bottled up in a finite arena where the intractability of the disagreements and the inescapable proximity of the conflicting parties can foster discontent, unrest, and violence lasting generations.

In practice, this might mean expanding to lunar colonies as near-Earth orbital habitats become too regulated or restricted by Earth governments or international treaties. On the Moon, disaffected individuals or groups frustrated with their circumstances in an existing settlement might decide to start their own settlements on or beyond the fringes of areas already settled or explored. As the lunar frontier ‘closes’ due to Keay’s “social specialization and assertion of central authority”, similarly frustrated settlers might decide to try their fortunes on the martian frontier, then among the asteroids, and so on through increasingly less-desirable properties.

It’s not like this hasn’t happened already, in our own history. The story of the Plymouth Rock Pilgrims, the Mormon migrations to Utah, and the “Go west, young man” ethos of the Old West were clearly manifestations of this same concept.

In the longer term, given some means of practical interstellar travel, this process of expansion-by-exile into the wilderness could happen on a vastly larger scale. If this turns out to be true, the ‘wilderness’ becomes effectively infinite.

Of course, this depends on a conservative view that we will continue to be recognizably human over such long time scales, as the development of new frontiers will likely result in an acceleration of technological innovation – including ‘transhuman’ technology like cognitive enhancements, targeted genetic improvements, or even ‘uploading’ into non-biological (or who knows, even non-physical) forms. What makes the expansion-by-exile concept useful for science fiction is that it can avoid the trap of having to tell a story from the difficult-to-conceive perspective of these transhumans by giving an author the choice among worlds on a spectrum of development — after all, given the Amish as a present-day example, it’s not difficult to imagine that some of those irreconcilable differences that might drive settlers into exile in the wilderness would concern the adoption of certain transhuman technologies, resulting in worlds (whether at the center or the periphery of civilization) whose inhabitants are still relatably human.

Promising Radiation-Exposure Treatments

This could certainly be useful in martian and lunar settlements, and perhaps moreso on the way to and from them – Researchers successfully treat previously lethal doses of radiation:

“The fact that this treatment can be administered up to a day after radiation exposure is so important,” said Millie Donlon, DARPA’s program manager for this effort. “This is because most of the existing treatments we have require they be administered within hours of exposure to potentially lethal radiation – something that might not always be possible in the confusion that would likely follow such an exposure event.”

The treatment – a combination of two readily-available and stockpileable pharmaceuticals – increases in mice the survival rate from a normally lethal dose to 80%, and there are indications it could be even more effective in humans. Note that it appears to treat only the immediate effects (“radiation sickness”) and there’s no mention of whether it reduces rates of long-term medical problems stemming from the exposure, such as cancers. Of course, one mustn’t be too greedy — I’m sure someone exposed to a lethal dose of radiation would consider the potential for cancer later in life an okay tradeoff to not dying a rapid and horrible death.

What might come of this discovery, if it does work as indicated?

  • Long-term space activities outside LEO (including transportation to and from deep space destinations) might be perceived as less risky if solar flares or other high-exposure events are less of a problem;
  • Spacecraft, stations, and surface facilities could be made simpler and lighter – if it’s accurate to consider this treatment as effectively raising the lethal dose (and again ignoring the long-term consequences in favor of short-term survival), structural countermeasures for extreme events don’t need to block quite as much radiation, and lighter or larger “storm cellars” become possible;
  • Nuclear power accidents become less hysteria-inducing (but then so might nuclear weapons use – c.f. Michael F. Flynn’s The Washer at the Ford)

Interesting.

Apparently, Resveratrol also has some anti-rad properties.
