Remembering Arthur Kantrowitz
Some thoughts from Eric Drexler. I only met him a couple times, but he was an impressive man.
“Hitler’s Last Days In The Bunker”
Hey, I think that it’s time (long past time) for Mike Griffin to go, but I think that characterization of his behavior in comments at this story is a little over the top. I mean, I don’t expect him to eat the muzzle after his wife takes poison. Though he does seem determined to burn the entire NASA budget to the ground rather than have it turned to some purpose that would actually open up space for the American people…
That said, the title of Bobby Block’s piece is a little understated. If his reporting is accurate (and we have no reason from past behavior of Dr. Griffin or others described to think not) he is being much more than a “transition problem” for the incoming president. This in itself, I think, speaks volumes about Mike and the NASA culture:
Those who spoke for this article, including a member and staff in Congress, NASA employees, aerospace executives and consultants, spoke only on condition that their names not be used…
…The Bush White House has pledged cooperation, and many agency leaders have told staff to cooperate fully. Griffin himself sent a memo urging employees “to answer questions promptly, openly and accurately.”
At the same time, he made clear he expected NASA employees to stay on message.
For example, transition-team interviews have been monitored by NASA officials “taking copious notes,” according to congressional and space-community sources. Employees who met with the team were told to tell their managers about the interview.
The desperation strong-arm tactics being used here are unsurprising, but are also not in keeping with an agency supposedly responsible to public accountability and the taxpayers. As anyone who has been reading this blog for long knows, I was not (to understate) a huge supporter of Senator Obama as a presidential candidate. But on the issue of space, I was largely agnostic, because I had no reason to believe that Senator McCain would be any improvement, and I was certainly not a supporter of president Bush on the issue, other than the basic concept of the Vision for Space Exploration (and a few bright spots, like White House support for COTS in the face of high-level NASA indifference). In this case, because I personally know some of the people on the space transition team, while I have had some policy differences with them over the years, I think that, relative to the current NASA administration, they are on the side of the angels. So I was gratified to read this:
…this week, Garver told a meeting of aerospace representatives in Washington that “there will be change” to NASA policy and hinted that Obama would name a new administrator soon, according to participants.
At this point, and particularly after reading this, it can’t happen soon enough for me. Here’s the real problem:
The tensions are due to the fact that NASA’s human space flight program is facing its biggest crossroads since the end of the Apollo era in the 1970s. The space shuttle is scheduled to be retired in 2010, and the next-generation Constellation rockets won’t fly before 2015.
Nearly four years ago, President Bush brought in Griffin to implement a plan to return astronauts to the moon by 2020 as a prelude to going to Mars. Griffin and his team selected Constellation, with its NASA-designed Ares I rocket and Orion capsule, as cheaper and safer than existing rockets. Constellation – especially Ares 1 — is the center of what Griffin sees as his legacy to return humans to the frontiers of space.
He wants to “return humans to the frontiers of space,” but he is perfectly happy to put forth a plan that ensures that it will only be a few humans (government employees) a couple times a year, for many billions per trip. Talk about Apollo on steroids.
It’s the Apollo budget on steroids as well, which is why Apollo was unsustainable financially. This is only one area in which he completely ignored, or even thumbed his nose at, the Aldridge Commission. As I recommended to the transition team, go read the report, and reflect on how much Mike Griffin’s NASA has deviated from its recommendations, and completely blown off the work of the contractors who worked to present options that would have been in keeping with it.
Unfortunately, due to the jobs issue and politics, it’s possible that this disastrous architecture will continue. But if it does, fortunately, it is pretty clear (though little consolation) that it will do so under new “leadership.”
[Thursday morning update]
In another dispatch from Bizarro World, in yet another display of his magnificent superhuman powers in miscomprehension of plain English, Mark Whittington writes that I (as opposed to the commenter at Bobby Block’s site, who I quoted in the post title) am comparing Mike Griffin to Hitler. He also demonstrates that he has no idea what Godwin’s Law is, if he thinks that I “violated” it.
Well, I guess it’s technically true if, by “comparing,” one means pointing out that he is not. I’ll “compare” Mark to Hitler similarly. Unfortunately, I’m less able to “compare” him in the same manner to Bozo the Clown.
[A few minutes later]
A funny (in a sad way) comment over at NASA Watch (I have a couple comments over there as well for Apollo worshipers):
Remembering that Mike Griffin explained his Orion/Ares system as ‘Apollo on Steroids’, and with what we know about steroid use, Mr. Griffin running off the rails like this [2 1/2 year old project two years behind? Don’t you trust what I’m telling you?] can simply be explained as the reaction of his body to heavy steroid use.
Verbally combative, liver damage, shrunken testicles. We’ll get back to you about the latter two effects.
I’ve heard it’s a tough habit to kick.
[Update about lunchtime]
Mark now updates, hilariously and delusionally, to fantasize that “my rage knows no bounds.” Only he would confuse amusement with “rage.”
[Update mid afternoon]
Dr. Griffin claims to be “appalled” at the Orlando Sentinel report. I think that, like people who when they apologize are really only sorry they got caught, he is appalled by the fact that his actions have been reported. I don’t see any denials of the specifics in his protest.
[Evening update (late evening on the east coast — I’m in LA)]
There’s a good discussion in comments on this topic over at Space Politics. “Anonymous.Space” has good commentary as usual, but this is a key point, I think:
…it’s the transition team’s job to ask questions, and Griffin should understand that and know better than to launch unprovoked, petulant attacks on them in a public setting. He, and more importantly NASA, need the transition team on NASA’s side. Griffin should be thankful that the NASA transition team is wholly composed of NASA boosters (most agencies are not so lucky), and work with the team in a transparent manner to develop the best possible set of materials and options for the new Administration. If Griffin is incapable of doing that, whatever the reason, then he should resign immediately. It doesn’t do Constellation, or NASA at large, any favors to have its Administrator engage in such uselessly childish behavior in view of the public eye, the new Administration, and the incoming Congress.
Considering that it was a Democratic administration coming in, this really is the best possible team that he could have expected. In fact, it’s pretty good even in an absolute sense, given their sympathy to both space settlement and NewSpace, which of course could be one of Mike’s problems with them. It’s quite likely that a McCain transition team would be much worse. I never heard any real signs of promise in McCain space policy during the campaign other than that Steidle was one of his advisors. There’s certainly nothing in McCain’s history to indicate that he would do anything interesting in space. It just happens that a lot (though by no means all) of the most devoted space activists are Democrats. Let’s hope they can make more happen this time than they did in the Clinton administration.

How To Implement Prop Depots?
With the (at least hoped for) imminent departure of Mike Griffin, there may be opportunities for more sensible approaches to carrying out plans to expand humanity into the solar system. One of the key elements will be propellant depots, and Jon Goff has some policy thoughts on how to (and how not to) make them happen. They echo some thoughts that I presented at Space Access on his panel on the subject in March, but he’s expanded on them quite a bit.
The NASAverse
Clark Lindsey has some thoughts on two parallel universes, in which one has orders of magnitude higher costs than the other. As he notes, I too hope that the new administration will reside in the one with the low costs, but if it does, it will be fought tooth and nail by legislators to whom jobs are more important than either taxpayers’ money or progress in space.
[Update a while later]
I see that, amusingly, Mark Whittington is foolishly attempting to lecture his intellectual betters on matters that he doesn’t understand:
If the sole purpose of Ares/Orion was just to get people into low Earth orbit, Clark would certainly have a valid point. But the purpose of Ares/Orion is to get people into Low Earth Orbit in a vehicle (Orion) designed to go to the Moon. Dragon doesn’t have to go to the Moon. (Of course, imagining a Dragon that could do that, with the extra radiation shielding, the extra consumables, and so on would be an interesting thought experiment. Could a Falcon 9 Heavy still loft such a vehicle?).
There is vastly insufficient difference between a vehicle that goes to the moon and one that goes to LEO to justify the cost difference between Orion and Dragon. A lunar mission requires a) additional radiation shielding, b) twice the thickness of the entry heat shield and c) extra consumables (two of which he points out). That doesn’t translate into orders of magnitude in cost difference by any sane cost model. As for “lofting” it, it doesn’t need to be lofted in a single flight. Once you break out of the notion that you have to do everything in a single launch, it becomes easy to build both a spacious crew capsule, and a service module with abundant consumables. But Elon’s BFR follow on would even be able to “loft” it in one go, and I’d be willing to bet that he could get there on a billion dollars or less, extrapolating costs from Falcon 1 and 9 development. Again, this could be done at much less cost (both development and operational) than is currently planned for the Orion/Ares combination. What part of already spent ten billion on Ares without its even having passed a legitimate PDR, while Elon has only spent a small fraction of a billion does Mark not understand?
This is pork, not progress.
[Late afternoon update]
Now Mark says I (in addition to fantasizing that I claimed to be his intellectual better) that breaking up CM and SM would require three launches “in a short time.” No. They would require two launches, one for each system element, and one or many launches for propellant, but none of which, other than the CM launch, would have to occur in “a short time.” Propellant could be stored on orbit for an indefinitely long time with proper depot design, and there is nothing intrinsically in an SM that couldn’t allow weeks or months of on-orbit LEO storage.
I don’t know where this myth comes from. People who want to justify tens of billions for a heavy lifter, I guess.
It Always Takes Longer Than You Think
Rob Coppinger (speculatively) answers the question “whatever happened to Blue Origin“? I really find their go-it-alone, and not be part of the community, or industry, attitude annoying, and wonder if they’d be doing better if they were more open.
And in the way of more speculation, Jon Goff makes some guesses about how SpaceX plans to recover their upper stage.
Space Solar Power And Launch Costs
There’s a long piece in this week’s Economist on the current prospects for solar power satellites. It’s a pretty good overview, but has a few problems. First of all, it doesn’t mention lasers at all. This is particularly a large oversight when it comes to the discussion of military applications. If space-based power is used for military logistics, it’s unlikely that it will be of the microwave variety — the power density is far too low to be practical for many of the envisioned needs. Lasers are more likely (though they will still not be a cost-effective weapon, despite the paranoia of some who will oppose the concept).
Also, in the discussion on launch costs, they didn’t spend enough time discussing the suborbital route, though they mentioned it. And while there was never much prospect of Gene Myers launching ETs into orbit, the chance that it will happen now is essentially nil, so the discussion of Space Islands is (at best) anachronistic. A description of Bob Bigelow’s activities with his orbital facilities, which weren’t mentioned at all, would have been much more useful and relevant to the reader.
[Update a few minutes later]
There seems to be a push on to get the Obama administration to adopt SBSP as a new energy initiative. Given all the other energy alternatives they want to chase (wind, terrestrial solar, etc.) why not? Even if it doesn’t pan out, it could result in lower launch costs for other things, which (as the report points out) are a prerequisite.
Armadillo Award Ceremony
Clark Lindsey live blogged it from NASA TV. It sounds like Mike Griffin said some good things about commercial space and the suborbital folks. But talk is cheap, and in any event, all indications are that he’s a short timer now. I hope that his successor says (and actually implements) the same things.
It’s A Start
We’re finally starting to take the asteroid threat seriously enough to start dedicating new telescopes to looking for them. A hundred million dollars seems like a pretty cheap insurance policy against another Tunguska or worse, in a populated area.
Unfortunately, we’re not developing the kind of spacefaring capability we need to do something about it if we see one coming. This is one kind of change that I’d be happy to see with the incoming administration. But it remains to be seen what space policy will come out of the process.
Good News, If True
I had suggested this to some people on the transition team, but I’m sure I wasn’t the only one. It looks like the Ares V RFP (and perhaps others) that was going to ruin (as is often the case) the contractors’ holidays with the need to work a proposal, is being postponed (and perhaps going away altogether — we can only hope). It’s a waste of money and contractor resources to force them to bid on a Phase I of a program that’s under review as to whether it should exist at all. Clearly, as noted over at R’n’S, Mike was trying to rush these things to entrench them and make them more of a fait accompli before he leaves, and fortunately, the incoming administration is having none of it.
I’m not sure how that worked, exactly, since they don’t actually have any authority until January, but (just as a guess) if I had been them, I would have told the contractors that I had no intention of funding the program without (at a minimum) a requirements review, which would imply (at a minimum) a rebid, and hope that they would in turn tell NASA that no one would bother to bid now.
