Jeff Foust has the latest on the Gateway debate. To me it’s insane to even think about launching a lander wet, but if they admit they could do it dry, it takes away a lot of the justification for SLS.

Starship Progress
SpaceX has shifted from composite to stainless steel, and will do initial flight tests “early next year.”
Mike Griffin
For Secretary of Defense?
I agree that we need someone who understands the technology threat at the helm of the Pentagon. But I wonder how familiar Goldman is with Griffin’s actual record when I read “praise” like this:
The overriding strategic risk to the United States is the loss of our technological edge, and the Defense Department needs a leader with the vision and expertise to restore it. Michael Griffin would be an excellent choice. A first-rate physicist, Dr. Griffin headed NASA under the Bush 41 administration.
First, Mike knows physics, but I wouldn’t call him a “physicist.” He’s first and foremost an aerospace engineer (not that there’s anything wrong with that). The problem is that, during his tenure at NASA, he devastated the space R&D budgets and promoted Constellation, an attempt not to develop needed new technology, but to repeat Apollo (except this time “on steroids”) with decades-old technology based on Saturn and the Space Shuttle.
At the time he left the agency (unwillingly) in 2009, all that was being developed to get back to the moon was a rocket designed to carry a capsule into low earth orbit, with no serious plans for things like a lunar lander, and those items were far over budget, and slipping more than a year per year (one of the reasons that, almost a decade later, we remain dependent on the Russians for access to our own space station). Even if they’d succeeded, the planned flight rate would be very low, at ridiculously high cost.
Now, in theory, he could argue that he is now older and wiser, and learned his lesson from that, but that’s negated by the fact that he continues to support their successors, the SLS and Orion. So, if we need someone to restore our technological edge, it’s hard to make the case that he’s the right guy for the job.
[Update a while later]
OK, if Mike Griffin were SecDef, just what would he do, going on past performance? Would he propose a giant expendable combat aircraft, based on parts from F-15s and F-16s, that would fly once a year, and each service could take a turn?
Trump, Conservatives, And “Neocons”
Some intellectual history from Jonah Goldberg, on the demise of The Weekly Standard.
The Space Frontier Act
It passed the Senate. I like the name, but the Lefties will hate it. I’m glad that the Office of Space Commerce is no longer under NOAA (I had discussed that issue with Jason Kim at lunch during the Galloway Symposium a couple weeks ago), and I don’t think we have to assign regulatory authority to it yet. Before we do that, we need to understand very clearly exactly what orbital activities are being regulated. Unfortunately, it’s unclear whether it will get through the House before the session ends.
[Update late morning]
Apparently the House is voting for it today, under suspended rules (they’ve pre-reconciled with the Senate), so it looks like it will go through as is.
The Paleo Diet
Forget it; go neolithic.
I’ve never been orthodox paleo. Basically, I’ve just cut way back on processed foods. I’m back to my college weight, my cholesterol is a little high, but the ratio is good, and my triglycerides are almost unmeasurable. I’m supposed to worry because both my parents died fairly young (father at 55, mother at 68) from coronaries, but they both were overweight, had terrible diets, and were inveterate smokers. Every time I check my arteries, no issues are found.
The Boring Company
I didn’t work up the gumption to go look at Elon’s tunnel last night, but Megan Geuss did. Most seem to have been less than whelmed.
[Update a few minutes later]
Elizabeth Lopatto took a ride, too.
[Afternoon update]
Gizmodo has a round up of pans:
Hopefully Musk and his engineers will be able to make the ride feel less like a dirt road sometime in the future, especially if they want to build this concept in Chicago, as they promised in a high-profile press conference with the mayor back in June.
But even if they make the ride more pleasant, where does that leave this transportation concept more broadly? There are plenty of underground highways in America. But they haven’t offered a very futuristic alternative. They’ve only delivered more single-family cars—which appears to be exactly what Elon Musk is putting in the pipeline.
Elon Musk has done some very impressive things with SpaceX and Tesla. But his futuristic Loop transportation system leaves a lot to be desired. Namely, the futuristic part.
Seems like the roll out was premature.
[Thursday-morning update]
Over at Popular Mechanics, a less critical review.

“Oh, No”
This is funny. The day that Trump learned to tweet.
I still don’t think he knows how to thread, though.
Dissing Virgin Galactic
You can find a NASA astronaut to come up with any opinion you want, but Andy Thomas isn’t impressed with SpaceShipTwo. I share the criticisms (which were made by me and others when the SpaceShipOne concept was first revealed), but I don’t think it’s doomed to failure. It offers a different experience than New Shepard, and will have its own market. I continue to find it ironic that the systems Burt added for “safety” probably added hazards instead.
Good Food Advice
Breads made with white flour have not only been stripped of all of their nutrients, but they might even contain remnants of the chemical used in the bleaching process. Our obsession with white foods (sugar, I’m looking at you) is totally odd and unfounded. The natural, unbleached version tastes the same (if not better) and is far more nutritious.
Not really. You should cut out the bread, period.
Why must everything that tastes so good be so bad for us? Our beloved creamy, fulfilling ice cream is extremely high in sugar and fat. And since milk is an animal protein, it’s also high in cholesterol. Sure, you can opt for some yogurt or a vegan dessert, but they’re not the same.
The problem with ice cream is the sugar, not the fat or cholesterol.
There is nothing wrong with ordering a regular cup of coffee (and you can even toss in a little half and half if you need it), but the calories add up very quickly when it comes to those fancy $7 coffee beverages. They taste so good because of all the added sugar and fat. You’ll get an immediate boost from a huge sugar rush, and then you’ll crash hard. Then you need another high-calorie coffee drink to feel better.
Again, it’s the sugar, not the fat or the calories that’s the problem here. Counting calories is junk science.
Bacon, sausage, and even cold cuts: they’re oh-so-yummy, but they’re just awful for your health. They contain high levels of unsaturated fat and sodium.
No, bacon has saturated fat. Which is good. And there is more danger from underconsumption of sodium than over.
A guaranteed way to add inches to your waist is to indulge in fried food. High in calories, fat, saturated fat, and carcinogens (yup, in those beloved french fries), there is nothing good about this. Except for their scrumptious flavor, obviously.
The problem with fried foods is not the fat, saturated fat, or calories (unless you’re frying it in seed oils, in which case the fat is bad because of the omega 6s). The problem with fried foods is carbohydrates in the batter. Deep frying dusted veggies in lard or tallow is fine.
