Gregg Easterbrook thinks that NASA should be saving the planet from errant asteroids, instead of building a moon base. He can’t avoid the usual straw man, of course, which makes much of the rest of his whining about moon bases suspect:
As anyone with an aerospace engineering background well knows, stopping at the moon, as Bush was suggesting, actually would be an impediment to Mars travel, because huge amounts of fuel would be wasted landing on the moon and then blasting off again.
Bush only “suggested” that to people who miss the point of the program. No one is proposing that every, or even any, mission to Mars touch base on the moon before going on to the Red Planet. The point was that the moon might be a useful resource for making Mars missions more cost effective, particularly if we can find water there, and deliver it as propellant to some staging point, such as L-1, which isn’t particularly out of the way en route to Mars. In addition, learning how to build a base on the moon, only three days away, is valuable experience to wring the bugs out of a Martian base, which is months away, despite the different environments.
But ignoring that, the real problem is that he doesn’t seem to understand NASA’s role:
After the presentation, NASA’s administrator, Michael Griffin, came into the room. I asked him why there had been no discussion of space rocks. He said, “We don’t make up our goals. Congress has not instructed us to provide Earth defense. I administer the policy set by Congress and the White House, and that policy calls for a focus on return to the moon. Congress and the White House do not ask me what I think.” I asked what NASA’s priorities would be if he did set the goals. “The same. Our priorities are correct now,” he answered. “We are on the right path. We need to go back to the moon. We don’t need a near-Earth-objects program.” In a public address about a month later, Griffin said that the moon-base plan was “the finest policy framework for United States civil space activities that I have seen in 40 years.”
Actually, Congress has asked NASA to pay more attention to space rocks. In 2005, Congress instructed the agency to mount a sophisticated search of the proximate heavens for asteroids and comets, specifically requesting that NASA locate all near-Earth objects 140 meters or larger that are less than 1.3 astronomical units from the sun–roughly out to the orbit of Mars. Last year, NASA gave Congress its reply: an advanced search of the sort Congress was requesting would cost about $1 billion, and the agency had no intention of diverting funds from existing projects, especially the moon-base initiative.
Now, I disagree with Mike that we don’t need an NEO program–I think we do. But unlike Gregg, I wouldn’t put NASA in charge of it. And if Congress wants to fund NASA to look for space rocks, it’s going to have to tell NASA not to do the other things that it wants to do, or fund it. Also, this was a little verbal gymnastics on Gregg’s part. Mike said that Congress had not instructed NASA to defend the earth, which is true, and the fact that they asked NASA to look for hazardous objects doesn’t change that fact in any way, despite his sleight-of-hand at the keyboard. Looking for objects is one thing–actually physically manipulating them is a different thing entirely. It’s like the difference between the CIA and the military. The former provides intelligence, the latter acts on it.
The Space Act (almost fifty years old now) does not grant NASA the responsibility to protect the planet, even with subsequent amendments. It is simply not its job. Moreover, no federal agency has that job, and as Gregg points out, if the US military were to take it on, there would be widespread suspicion on the part of the rest of the planet, and it would open us up to tremendous liability if something went wrong (not that there would necessarily be any lawyers around to care).
And is it really the job of the military? Again, as Gregg points out, this is a natural problem, not an enemy. If ET, or Marvin the Martian presented a threat, it would make sense to get the Air Force (or if we had one, Space Force) involved, because that is a willful enemy to be engaged, which is what we have a military for.
But as I’ve written before (six years ago–geez, where does the time go?), the only historical analogue (at least in the US) we have for planetary defense is the management of flooding by the Army Corps of Engineers. This is a predictable (though not as predictable as an asteroid or comet strike) natural disaster, at least statistically, and one that can be managed by building dams, which is largely what they do.
Now, I’m not proposing that the ACE be put in charge of defending the planet, but that thought isn’t much more frightening than putting NASA in charge of it. Yes, Gregg, we could lobby to get Congress to amend the Space Act to put it in the agency’s portfolio, but do you really think that would be a good idea? NASA is fifty years old this year, and bureaucratically, it acts much older than that. You don’t want to take an existing agency, with too much on its plate, and too little resources with which to do it (and yes, much of what it’s doing it shouldn’t be doing, but that’s a different discussion) and give it such an important, even existential task. It worked fine in the sixties, because it was a young, new agency with a focus on a single goal (though it managed to accomplish a lot of other things along the way in terms of planetary exploration–Tom Paine once told me that there was so much going on during Apollo that NASA did a lot of great things that it didn’t even know it was doing).
No.
I’ve often said that if the president really thought that the VSE was important, he would have taken a policy lead from the Strategic Missile Defense program in the eighties, in which an entirely new entity was established to carry it out (SDIO, now BMDO), because it would otherwise get bogged down in blue-suit politics in the Air Force.
I agree that we should be doing much more about this threat than we are, but just because NASA is ostensibly a space agency doesn’t mean that they should be in charge of it. I would establish a planetary defense agency, which had that as its sole charter. It might ask for (and occasionally get) cooperation from NASA, but it would do the same with the Air Force, and it would put out contracts to the private sector, and it would coordinate with COPUOS and encourage other nations to establish such entities to enter into cooperative agreements. If you ask NASA to do it, it will just become one more boondoggle, or it will get buried in the agency’s other priorities. Either way, if it’s important, you don’t want a sclerotic agency, long past its sell-by date, to be in charge.
