A conversation with him. The transcription has a few problems, but it’s interesting. His thoughts on space tourism:

Much like the airlines once you get more people you got to fly the cheaper the flight, the tickets cost or the more tickets you could sell the cheaper it is to operate an airline and you get this happy, just the opposite of the death spiral that some people talk about. So I think that there are a lot of people today, and I don’t mean billionaires, who would pay a fair amount of money to uh… I don’t mean just go up on a rock and come back to L.A. I mean go into orbit for a day or two and look through telescopes and have lectures on space, experience weightlessness and get to get sick and all these great things. But I do think that that will be the change agent. I don’t see anything that’s going to reduce the cost of space transportation by a factor of 10 other than a much higher volume…

And if we can get people involved, and I think we can, in tourism it will make a lot of difference. I’ve had the good fortune to, I’m kind of an amateur explorer or whatever and I’ve been to the South Pole three times and the North Pole once I’ve rafted the Grand Canyon and I you know you go through this long list of stuff. And people say well you know not many people want to go into space. Who would want to do that? Well I think back when I rafted the Grand Canyon I think there were 14000 people a year going through the Grand Canyon on a raft at that time. If you’d ask Wesley Powell the first person to do if, what 75 years later 14000 people will be into the canyon he would say you’re crazy if you’d asked the Wright brothers that the population of Detroit gets on an airplane every day and complains because they’ve already seen the movie and the food’s bad. The Wright brothers would have thought you were bonkers or something. You know there are many other examples one can go through of that kind of thing and people do want to experience these things and I think that will be the biggest change agent of all.

I’ve been preaching this for three decades.

Falcon Heavy

Leonard David has a story on its prospects for initial success, with quotes from Yours Truly.

To expand on the point, while he didn’t include it, I told Leonard in email:

The other issue is not launch reliability, but schedule reliability. SpaceX has aborted launches of the Falcon 9 when one or more of the engines was indicating performance issues on ignition. Three times as many engines means a lot higher probability of having an issue with one of them. For example, while I don’t know what the ignition reliability of a Merlin D is, suppose it’s 99% (that is, there’s a one in a hundred chance of failure to perform up to spec on ignition). For nine engines, that means the probability of a Falcon 9 aborting on the pad due to an engine issue would be one minus 0.99 to the ninth power, or about 8% per flight, or about once every dozen flights (which doesn’t seem that far off from their record). I don’t know what their flight rules will be for the Heavy, but if they have the same rule that they can’t take off with an underperforming engine, the reliability for twenty-seven engines will be one minus 0.99 to the 27th power, or 24%. That is, if they’re only 0.99 reliable per engine, and require all engines operating properly to take off, they have about a one in four chance of aborting a Falcon Heavy every single flight. That says to me that either they think Merlin reliability is greater than that (which it could well be) or that they’ll relax the rules to allow engine out from liftoff, or perhaps both.

Regardless, here’s hoping for a successful flight in less than three months.

Totality

Here’s the difference between 99% and 100%.

[Friday-morning update]

“I’ve always thought eclipse chasers—these people who spend thousands of dollars flying around the world to spend two minutes looking at a solar eclipse—were a little nutty. I mean, that’s a little extreme, right? If you want to see what a solar eclipse looks like, type solar eclipse into Google.”

I was wrong.”

The Dozenth Flight

I’m not going up to Vandenberg for the Formosat launch, but I’ll probably go to the beach (I’m assuming the marine layer will clear by then). I’d like to see SpaceX get to twenty flights this year, but I’d like even more to see them finally launch the heavy.

[Update a while later]

This is interesting, if true: Space will lose millions on this mission. Of course, it would have probably cost them a lot more to continue with the Falcon 1e. This is also the first time I’ve ever seen the marginal launch costs stated, at $37M. Also interesting, if correct.

Trump Versus Bezos

Why does Trump hate him so much? Because, as Virginia Postrel points out, Bezos is the anti-Trump:

Trump, who likes his staff to have the right “look,” would never cast a wiry guy who doesn’t hide his lack of hair as a big-time businessman. How can someone only five-foot-nine intimidate people into submission? In Trumpworld, intimidation, not value-creation, is what business is all about.

Bezos also has a sense of humor, often at his own expense, and a famously raucous laugh. Trump is humorless. He certainly doesn’t laugh at himself.

Bezos speaks clearly and has amazing message discipline even by the standards of successful CEOs — something that struck me when I first interviewed him way back in 1996. Trump: not so much.

Trump grew up rich, went to private schools, and had an undistinguished college career. Bezos grew up middle-class, went to public schools, and knocked the top out of Princeton, graduating with highest honors and Phi Beta Kappa in electrical engineering and computer science. One had a rich father; the other has brains.

Ouch.
