A bit of Martin Marietta artwork depicting the Titan IVA, rescued from ebay. I’ve put the full-rez scan (600 dpi, so it’s pretty big) in the 2017-11 APR Extras Dropbox folder, available to all APR Patreon patrons at the $4 level and above.

Seems they’re stepping up their game:

North Korea missile launch: The most important things to know

The most recent missile reached an altitude of about 4,475 kilometers. Experts believe that this missile has the range to reach *all* of the United States. However, the warhead, which the Norks of course are claiming was super heavy, might have been light; it might have even been another stage. Still, even if they were only chucking a soccer ball at Florida, it’s an impressive achievement for a nation full of intestinal worms.

I would be utterly unsurprised if the missile is not even remotely accurate… they shoot it at Washington, D.C. and it hits Ohio. However, it would be a much less challenging mission to deposit a single warhead a few hundred kilometers above the central US in order to set off an EMP. If they were successful in pulling that off, the death toll would be horrendous. Estimates I’ve seen go up to a death toll of up to 90% of the American population due to the subsequent collapse of the power and transport infrastructure; famine would quickly follow, but not as quickly as major cities like Chicago and New York eating themselves. However, an EMP that takes outt the US civilian power grid would do close to diddly squat to the US military… so for a few days at leas thte US military would lash out and turn North Korea into ruined wasteland. it’s a safe bet that the moment the Norks launch that EMP weapons, they’ll launch an attack on South Korea. So the death toll in North Korea would be close to total; the death toll in South Korea could be millions. And the Japanese might get in on it.

And of course once the US has been shut down, it will be clear to everybody else that Team America World Cop is out of business. Russia will invade all its neighbors. China and India and Pakistan will probably go at it. The Arab world will go after Israel. The death toll could be in the billions, and civilization could come to an effective end.

With that possibility, the math on launching a pre-emptive nuclear strike on North Korea starts looking better.

I’ve put five of my large format cyanotypes on ebay, with starting bids far lower than the usual selling price.

The headline is more than a little misleading. “Mad Mike” here isn’t a rocket scientist; in fact, this actual-Flat-Earther states quite clearly that he doesn’t believe in science. Still, he spent a whole lot of money building himself a “skycycle”- like rocket vehicle with which to lob himself into the air.

If you have time to kill and want to chuckle sadly, take a look at this winners Facebook page. He’s not just any Flat Earther, he’s one of those belligerent ones. He thinks that somehow lobbing himself a short distance into the sky will “prove” the Flat Earth delusion to be true… where somehow decades of high altitude balloons, sounding rockets, orbital flights and missions to the moon and beyond somehow all seemed to miss it.

And if there was any lasting doubt that the news media is just not very good, here’s a collection of headlines that will make aerospace engineers – including former rocket engineers like myself – want to pull their hair out:

Self-Taught Rocket Scientist Mad Mike Hughes Plans to Launch Over Ghost Town

This barmy self-taught scientist called ‘Mad Mike’ is going to launch himself over California in a homemade rocket

Not only is there a whole lot of copying off each other – rather than, you know, actual journalismizing – there’s the repeated mis-use of the word “scientist.” Even disregarding the fact that he doesn’t believe in  science, there’s the basic fact that he’s not actually *doing* any science.

A recent acquisition from ebay was a pretty good B&W glossy showing a Martin Company illustration of the Titan IIIC launch vehicle, circa August, 1964. One of the better Titan IIIC illustrations I’ve seen, showing the innards to good effect.

I have uploaded the full 600-dpi scan to the 2017-11 APR Extras Dropbox available to all $4 and up APR Patreon patrons. It’s in two formats… the raw scan, and a cleaned-up version that looks better. Also included is the press release printed on the back of the glossy. If you are interested, take a look at the APR Patreon and consider signing up.

Currently being sold on ebay is a display model of a missile, a “Martin ASM.” ASM almost certainly means “Air to Surface Missile,” but otherwise there’s no further info. Seller seems to think it’s related to the Assault Breaker project, but it looks vaguely like a Skybolt-ish air-launched ballistic missile.

A rare piece of color art depicting an early Dyna Soar being dropped from a B-52. The Dyna Soar is equipped with two rocket engines used to boost it to higher altitude and higher speed (supersonic, though not very supersonic… think the test flights of the M2-F3 and the HL-10). Note that this shows the Dyna Soar having been tucked into a modified bomb bay in the B-52’s fuselage; planning would soon move the Dyna Soar to under the wing, using the same attachment point used by the B-52 to carry the X-15 and the lifting bodies.

The Space Review has an interesting piece that attempts to figure out how much BFR might cost to fly. My own estimate: I dunno. Done the old fashioned way, you’d go through a thousand pages of calculations, totaling up all the palm-greasing and bonuses and regulatory hoop-jumping and congresscritter bribes and extraneous R&D and sub-sub-subcontractor troubleshooting… and only then try to figure out what the actual manufacturing and testing and propellant and operations and maintenance will cost. And then tack on an extra zero, because of course you will. But here, SpaceX is operating in a whole new environment. Ten years ago I would have said the BFR would have been a ridiculously, laughably optimistic concept; now… you know, I bet they can pull it off, even if they need to slip the schedule some.

Estimating the cost of BFR

They come up with a conclusion that $240,000 per ton delivered to the surface of Mars is achievable. They also come up with a cost per seat of $1,200 for a point-to-point ballistic transport version stuffing 853 passengers on board, but here I become distinctly dubious. I’d bet real money that even if the technology works fantastically, the regulatory banhammer will come down on SpaceX SpaceLines the moment they try to actually fly passengers. Heck, I bet the US FedGuv will drop ITAR on SpaceX like a ton of white-hot bricks the moment SpaceX seriously proposes to launch  a BFR upper stage to some darned furrin country like Japan or Australia, never mind China or Dubai. Plus there will be practical issues which I think stand a *very* good chance of torpedoing an affordable ballistic transport system… passengers keeling over due to acceleration (or being ejected from the boarding line because a doctor says “no”), the sort of delays that space launch systems would find trivial would be monumental for a system meant to operate for only 30 minutes, difficulties getting passengers loaded on board, bad weather at the launch or landing site making it impossible for the vehicle or its booster to safely land… these can all cause a serious headache.

I am much less interested in the global transport aspect than I am in the orbital and interplanetary aspect. Sure, it’d be great to have a half-hour-to-antipodes transporter… but that wouldn’t have one percent the impact that a colony transport to Mars would have.

SpaceX has landed another previously-launched Falcon 9 first stage (it flew a resupply mission to ISS in February). It’s not there yet, but this sort of thing is becoming routine… which is fantastic.

Note that at about the 21 minute mark the grid fins begin to glow white-hot during entry. Which would certainly explain why they switched from aluminum to titanium for those fins.
