Asilomar Two

Here’ is the first report I’ve seen on the conference this past week on geoengineering. I would have like to attend, but didn’t have either time or money right now. I was a little disturbed by what seemed to be an absence:

Participants…split into groups representing the two broad kinds of geoengineering: methods which block solar radiation from the sun, like spreading aerosols in the stratosphere, and techniques to remove carbon from the atmosphere, like growing algae blooms at sea.

…A vexing question for participants was the role of commercial companies in this controversial field. A breakout group devoted to the idea of blocking sunlight—by whitening clouds or the ocean surface, for example—couldn’t agree on whether it should propose barring for-profit companies from the enterprise.

Ignoring the issue of the role of private enterprise, what I’m reading seems very terracentric (which isn’t uncommon among the scientific community — I think it was one of the reasons that it there was so much skepticism about Alverez’ dinosaur-extinction theory). After all, if the goal is to block sunlight, the closer to the source you are, the easier the job might be. Maybe there were some space-based solutions discussed, but you can’t figure it out from this report. One of the reasons that I wanted to attend was to provide a perspective that might not otherwise be there, and it looks like my fears were born out.

I’d bet that if you proposed (say) Ehricke-type solettas, or sunshades, you’d be laughed out of the room, largely out of ignorance of space transportation economics. I would have provided a tutorial to explain why it’s foolish to extrapolate costs of current launch systems to future large-scale space access, because I’ll bet that’s exactly what most of them would do (because it’s what most people do now). I’ll look forward to a more detailed report on the conference, though, including a full list of presentations.

[Monday afternoon update]

It should be noted that I’m not advocating geoengineering. I’m just pointing out that for those who do, they shouldn’t exclude space-based solutions because of false preconceptions. It’s sort of like my attitude toward NASA. I wouldn’t weep much if the agency was defunded (other than the personal impacts on my friends who are employees and contractors). But seeing as how that’s unlikely to happen, I’ll continue to lobby to at least have the funds spent sensibly, in terms of actually advancing us in space.

Good News On ITAR

I’ve long said (to paraphrase Mark Twain) that ITAR is like the weather — everybody talks about it, but no one ever does anything about it. Well, that may be about to change:

The legislation gives the president the authority to remove satellites and related components from the US Munitions List (USML), hence removing them from the jurisdiction of ITAR. (It would not, though, allow the export of such items to China.) Other provisions of the legislation would direct an ongoing review of the USML “to determine those technologies and goods that warrant different or additional controls”, which could benefit the space industry even if the White House didn’t exercise the provision to remove satellites and related components from the list wholesale.

The legislation passed the House last year, but for several months has been sitting in the Senate, raising fears they may never consider it. But speaking on an ITAR panel at the Satellite 2010 conference last week, David Fite, a staffer on the House Foreign Affairs Committee but speaking only for himself, said things were going “somewhat on schedule” compared to authorization bills in previous Congresses. That schedule would have the Senate passing its version of the authorization bill by the summer and a conference report reconciling the differences between the two in September or October.

It’s unclear from the reporting whether or not this will fix the problem for launch providers, or just satellite manufacturers. For instance, will it make life easier for the suborbital folks? Of course, the biggest problem is this:

“We are in an election year,” cautioned Fite. In his 11 years on Capitol Hill, he said, “I have never seen an environment that has been this partisan.” Bill Reinsch, president of the National Foreign Trade Council, concurred. “The danger is that this will become a political issue in an election year, which means it’s not going to be addressed on its merits, it will be addressed by slogans.” That will make it harder for reform to make its way through Congress and could also hurt the administration’s other reform efforts.

I’ve also long said that, as it took Nixon to go to China, only the Republicans can fix ITAR (though Duncan Hunter made sure it would never happen all through the Bush administration) because the Dems can’t afford to look weaker on national defense than they already do. I do fear very much that this will become a casualty of the very ugly campaign we’re heading into.

Another Expired Obama Position

In this case, it’s a good thing. Back during the campaign, when John McCain proposed an automotive prize, then-Senator Obama derided it:

Explaining that “when John F. Kennedy decided that we were going to put a man on the moon, he didn’t put a bounty out for some rocket scientist to win,” Obama believes that to speed alternative fuel development and increase fuel-efficiency, the full power of the government must be combined with the “ingenuity and innovation of the American people.”

But now, Jonathan Adler says that Obama has his eye on prizes:

Earlier this month, with little fanfare, the Obama Administration took a small but significant step toward encouraging greater technological innovation. On March 8, the Office of Management and Budget issued a guidance to federal agencies on the use of challenges and prizes to spur technological innovation. This memorandum seeks to “strongly encourage” federal agencies to “utilize prizes and challenges as tools for advancing open government, innovation, and the agency’s mission.” It further explains that many federal agencies have sufficient statutory authority to create technology inducement prizes with existing funds and spending authority.

This is particularly good news for NASA, because Centennial Challenges needs an infusion of funds. Fortunately, the current NASA administration is very supportive of this sort of thing, and can be expected to support new prize activities if they get the budget for it.

Back To The Drawing Board?

I’ve never been a big fan of nuking asteroids, but this test should cause some concern:

Don Korycansky of the University of California, Santa Cruz, and Catherine Plesko of the Los Alamos National Laboratory in New Mexico simulated blowing up asteroids 1 kilometre across. When the speed of dispersal was relatively low, it took only hours for the fragments to coalesce into a new rock.

“The high-speed stuff goes away but the low-speed stuff reassembles [in] 2 to 18 hours,” Korycansky says. The simulations were presented (pdf) last week at the Lunar and Planetary Science Conference in Houston, Texas.

So you have to have a big enough bomb to really do the job. I think there are better, more controllable ways.
