Another Apollo Astronaut Weighs In

Rusty Schweikart steps up to the plate in support of the new policy. I don’t agree with all of it — I think he misses the point in some cases, but I like this:

Are we, in fact, on a dead end road? In answering this critical question you should not overvalue either my opinion or the opinions of my fellow astronauts, but rather focus on the considered and thoughtful, and even hard-nosed, analysis of the panel of experts who dealt explicitly with this, the Augustine Committee on our Human Spaceflight Program. Norm and his panel are very experienced and highly qualified academics, business leaders, astronauts, and space program executives. I have immense respect for them and their considered judgment. They performed a thorough, open and difficult review and analysis of where we are. Their conclusions were not reached lightly nor did they shy away from calling it as they saw it. I take their work and their conclusions very seriously and I believe you should as well.

Note that he’s not asking Senator Nelson (as others have) to take his word for it because he’s an astronaut — he’s citing someone who has actually studied the current problem (as opposed to a different problem that we had to solve half a century ago).

But I disagree with some of his arguments. First:

Technical arguments can and have been made to support this intermediate step, and they are not without justification and support. Nevertheless, in my opinion, the arguments for necessity are fundamentally weak, and in any event are overwhelmed by the widely held and devastating question “been there; done that… tell us why you’re doing that again?” Why, after 60 years, should we be devoting incredible resources and effort to going back to the Moon instead of to a challenging, pioneering new goal? As Norm Augustine stated in your 12 May hearing, the long term space program has to be supported on a continuing basis by the public, and the public simply will not maintain support to reliably sustain a monumental and expensive effort to do again what we did 60 years before. This is especially true of young people, who are hardly inspired by a goal of repeating their grandparent’s achievements.

The problem here is that he is confusing the goal of going to the moon, as established by the VSE, with the means (Constellation) chosen to achieve it. Yes, we don’t want to do Apollo again (and that was what Mike Griffin proposed, explicitly declaring it “Apollo on Steroids”). But that doesn’t mean that we shouldn’t, or don’t want to go back to the moon, if it can be done in an affordable, sustainable, and useful (which is a key attribute of sustainability) way. This problem will pop up again a little later in his letter. But he thinks that the problem is one of destination, and (surprise, surprise) he likes the asteroid mission.

As I’ve repeatedly said, destinations are beside the point, other than that they be beyond LEO. There is basic infrastructure needed to do so on a cost-effective basis, and once that’s in place, where we go is a relatively minor detail, which can be addressed by small additions to the infrastructure (a lunar lander for the moon, a long-duration ship with radiation protection for deep-space missions). But until we get that basic infrastructure in place, which won’t occur for years, even if we start now, arguing about the specifics of what we’re going to do with it is a dissipation of valuable political energy that would be better served to make sure that we get it, so we later have something to argue about (or more likely and preferably, options to do whatever we want).

He follow up with another confusion between VSE and Constellation, in “explaining” the Gap:

The sad state of our current space program, and the gap in particular, is a given. An unfortunate, but unavoidable given. We are here because of the complete mismatch between the program announced by President George W Bush in early 2004 and the inadequate funding which was subsequently sought and allocated since that time. As Norm Augustine testified before your committee on May 12, in the 4 years between the announcement of those ambitious goals and the time when his Committee conducted its comprehensive review of human space flight, the Ares launch vehicle development slipped between 3 and 5 years. This slip, combined with the planned termination of Space Shuttle operations in 2010 created and ultimately extended the “gap” in our nation’s ability to launch astronauts into orbit to 7 years or more. This gap, during which time we will be dependent on the Russians to launch our American astronauts to the ISS, was created during the prior space program. It is a given and it cannot be eliminated.

Emphasis mine.

Note that he (like many Constellation defenders) claims that there was a “mismatch” between Bush’s program and the funding. But this simply is not true. The mismatch was between the funding planned for the VSE and the program that Mike Griffin later chose to implement it. George Bush never said anything about developing an Ares I and Ares V, and it was the decision to go that route that cratered the budget, and created the sinkhole into which funding for all other aspects of the VSE disappeared. It continues to be frustrating that people commenting on this, who should know better, continue to misstate history, as I pointed out this weekend.

How Much Does Safety Cost?

And how much should it cost? Over at my Pajamas Media piece this weekend, frequent TTM commenter “bbbeard” comments:

SpaceX has a launch record of 3 complete failures and two successes. What is disturbing about the SpaceX failures is that they hinged on relatively major oversights. Take the Demo2 flight, for example. SpaceX’s post-flight analysis showed that incorrect propellant utilization parameters were uploaded into the engine computer, a textbook case of sloppy configuration control. There was a recontact during staging, which initiated a slosh event — that was not mitigated because the LOX tank had no baffles. These are the kind of rookie mistakes that get you labeled as a “hobbyist”. It will take more than two successful flights to show that Elon Musk’s company has outgrown its hobbyist mentality and is ready to tackle human spaceflight.

Safety is the elephant in the foyer that you have not addressed. STS has suffered two launch failures in 132 missions (counting Columbia’s foam strike as a launch failure) — and what no one in NewSpace seems able to admit is that that loss rate is unacceptable. You can deny all you want that NASA is up to the job of designing a vehicle significantly safer than STS, but it is a fact that Ares is being designed to tough and unprecedented requirements for loss of crew rates — and Atlas and Delta never were. You claim Atlas has an “unbroken string of many dozens of successful flights” but by my count only 20 of the 21 flights of Atlas V have been successful — and that is an unacceptable loss rate. Only 2 out 3 Delta IV-Heavy flights have been successful — and that is an unacceptable loss rate.

Unlike SpaceX, the engineers at Boeing and Lockheed are the best in the business. But they were never directed to make Atlas and Delta reliable enough for human spaceflight. Using those platforms as human launch vehicles would be a step backward from STS safety levels, which are already unacceptably high.

What your argument boils down to is that you, Rand Simberg, think that the extra reliability that Ares aspires to is not worth the price tag. You may be right, you may be wrong. But why won’t you explain that that is your argument, instead of simplistically blaming NASA for poor cost control?

Man, there’s a lot to unpack there. I don’t know if I have time to deal with it right now, but let me at least lay out the issues. One is what an “acceptable” level of safety is (particularly relative to the reliability required to deliver a satellite worth a billion dollars). Another is how it is achieved. A third is how much it should cost to do so. A fourth is how much someone who had pretty much the same experience as other “professionals” in developing rockets for the first time can be said to be a “hobbyist.” (I would note as an aside that I don’t intrinsically accept “hobbyist” and “amateur” as pejoratives vis a vis “professionals” — many amateurs and hobbyists can be better than professionals — they just don’t choose to do it for a living. Space historian Henry Spencer comes to mind. I don’t think that there is anyone on the planet who is more familiar with both space history and space technology than Henry, but it’s not his day job.)

Anyway, I’m trying to figure out how to earn a living myself, so have at it in comments for now. I may weigh in later.

Payton Comes Around

Remember a few weeks ago, when the Ares huggers were seizing on comments by Gary Payton that cancelling Ares would double costs for the Pentagon’s solid motors? It never made any economic sense, but it was used as cudgel, however dull, in the battle over the new policy. Well now he’s saying that not only will the effect be trivial, but that it actually benefits the DoD to have more users of the EELVs:

Q. What does the cancellation of Constellation mean for the Air Force?

A. If there are increases to the Evolved Expendable Launch Vehicle (EELV) annual launch rate, that’s a good sign. Right now, we have a plan for United Launch Alliance to do eight launches a year, notionally five for the Air Force, two for the National Reconnaissance Office and one for NASA. So if we can increase that one for NASA up to two or three per year, that would be great for everybody, because we would be buying more rocket engines per year and flying more rockets per year, and that helps with the proficiency of the launch crews…

Q. Are you concerned about the Constellation decision’s impact on the solid-rocket motor industrial base?

A. We’ve come to find out that it has a trivial impact on space launch because we don’t use the big 3½-meter segmented solids on our EELVs; we use solids that are about 1½ meters in diameter.

Well, pardon me, but DUH.

I could never understand why the Pentagon went along with Constellation in the first place.

Fact Checking The EPA

I was doing a little research on the mess, and wanted to get some data on the Gulf. According to the EPA, it has a volume of 642 trillion gallons. This seems off by three orders of magnitude to me (that is, I think that its 642 quadrillion gallons — 1015th, not 1012th — which is what a trillion would be).

My calculation is based on the stated area of 600,000 square miles (which seems reasonable to me), and average depth of 1600 meters (why do they have to mix their units?), which is about 5100 feet. Multiply the square miles by 5280 squared, and you get about 17 trillion square feet. So the volume has to be three orders of magnitude more than that, and it’s another order of magnitude (7.5 gallons per square foot) when you convert to gallons.

Am I off, or are they?

Yeah, I want these people to be in charge of regulating carbon emissions (including, no doubt, my exhalations).

[Update late afternoon]

Why do I care, you ask? Because people are saying that with the new estimate of the leak rate, this is the equivalent of “n” Exxon Valdezes per week, where n varies with the commentator. But the Gulf isn’t Prince William Sound. Based on the number of 11,000 square miles affected in Alaska, and an average depth of a thousand feet (generous, I think — the deepest point in sound is 2000, and most of it is a lot less, even when you get out around the Kenai Peninsula), I get a ratio of volumes of on the order of 300, so we’d need a lot of Exxon Valdezes to make it comparable to that disaster. I don’t know whether the warmer temps of the Gulf make things better, or worse, though.

Is Kagen Anti-Gun?

Probably. I’d be pretty surprised to learn that she agreed with Heller, for instance. I have to say, I’m in no big hurry to see Stevens replaced, because any of Obama’s nominees are likely to be disastrous for decades. This was in fact the biggest reason to prefer McCain in 2008 — to prevent, or at least mitigate, such long-lasting damage to liberty.

America Is A Campus

…and Obama is our dean. Complete with speech codes, apparently. Glenn Reynolds disagrees somewhat:

Nonsense. No Dean would rock the boat so rashly, or offend the money folks so gratuitously, or put the college into so much debt. On the other hand, Hanson hits the nail on the head in other ways.

Yes. Like the president’s credentialism hypocrisy on Kagen versus Miers. Not to mention himself.

from Jay Nordlinger:

I hope I have read that incorrectly, or am interpreting it incorrectly. Did we, the United States, talking to a government that maintains a gulag, that denies people their basic rights, that in all probability harvests organs, apologize for the new immigration law in Arizona? Really, really?

…Do you ever get the idea that our government is a bunch of left-wing undergraduates come to power?

Every day.

A Space Glossary

The other day, a commenter said that he thought that Constellation was just the rocket and capsule. Many people don’t know what Constellation (and other things) are, and aren’t, which is what feeds part of the ignorant hysteria that we’ve seen in the press and on the Hill since the new budget was bumblingly introduced in February (and unfortunately, the administrator remains poor on his messaging and communications capability, with his talk about “bailouts” for the commercial sector). Anyway, as a probably futile attempt to clear the fog, I have a glossary and explanation up over at PJM today.
