“Blowback”

Lee Harris points out the fatal flaw in the argument of the “non-interventionists“:

We may agree with Ron Paul that our interventionist policy in the Middle East has led to unintended negative consequences, including even 9/11, but this admission offers us absolutely no insight into what unintended consequences his preferred policy of non-intervention would have exposed us to. It is simply a myth to believe that only interventionism yields unintended consequence, since doing nothing at all may produce the same unexpected results. If American foreign policy had followed a course of strict non-interventionism, the world would certainly be different from what it is today; but there is no obvious reason to think that it would have been better.

How Precise Are Clocks Getting?

This precise:

To tap the F1’s full accuracy, scientists have to know their precise relative position to the clock, and account for weather, altitude and other externalities. An optical cable that links the F1 to a lab at the University of Colorado, for example, can vary in length as much as 10 mm on a hot day — something that researchers need to continually track and take into account. At F1’s level of precision, even general relativity introduces problems; when technicians recently moved F1 from the third floor to the second, they had to re-tune the system to compensate for the 11-and-a-half foot drop in altitude.

This Is The Place

If you see this post, you’ve found the new server, and you can comment again.

This move is long overdue. It will give me more bandwidth, and more disk space, and more up-to-date tools. I may start doing more multi-media stuff, but that will depend on my time availability.

And yes, I should do a site redesign, too, but I’ve always been one more for function than form.

Site Move

I’m moving to a new server. I’ve shut down comments on this server. You’ll be able to comment at the new site once you get there. I’ll be putting up a new post on the new server, announcing that the move is complete. If you see it, you’ll know that you’ve found the right place, and can comment again.

SpaceX Update

Elon Musk has a long update on progress on the new Merlin engine, the Falcon 9 and Dragon. Those are the first pictures I’ve seen of the Hawthorne facility. It sounds like they have a lot of room to grow.

I’m disappointed, but not surprised, that they’ve gone with hypergolics for reaction control. That’s going to complicate turnaround.

But overall, (in contrast to Orion/Ares) progress seems to be good. Note that they’re continuing to hire, and even offering bounties, if you know anyone to refer to them.

[Update a few minutes later]

SpaceX should look into this engine for RCS. Presumably, the hypergolics were chosen for reliability (no igniter required) and storability, but XCOR has pretty reliable engines, and they don’t use such nasty propellants, and they have been working on well-insulated LOX tanks.
