Dynetics has a UAV designed to be launched from and recovered in flight by larger aircraft. The UAV looks like a cruise missile, but is meant to carry a variety of recoverable payloads such as recon, communications and targeting systems. The video below kinda buries the lede: it starts off with several minutes of “meh” computer graphics, and *then* goes to video showing that important portions of the actual systems have been built and flight tested. They don’t seem to have gone as far as in-flight recovery of powered vehicles as yet.

The recovery rate planned for 2019 seems kinda slow: 4 in-flight recoveries in 30 minutes. *Eventually* I bet AI will get good enough that the recovery system will be reduced to approximately nothing, just a net *inside* the cargo bay. The Advanced Gremlin will just fly itself right into the rear door of the C-130  and shut its engine down, perfectly timed so that it is gently snagged in a net, and then a roboarm will swiftly reach out, grab the vehicle and put it in a rack. One recovery every few seconds. A *really* advanced system would have the Uber gremlins fly themselves straight into a rack, no roboarm needed.

Clickbaity headlines like that usually disappoint. But, dayum, this’n looks kinda bad:

Ground Zero of Amphibian ‘Apocalypse’ Finally Found

Short form: in the 1950’s a fungus broke out of the Korean peninsula and began to spread around the world. This fungus attacks the thin skin of amphibians and turns it to mush; some places have seen their amphibian populations essentially wiped out. The fungus can apparently be effectively treated with a topical compound, but I doubt we’ll be seeing major efforts to send armies of people into swamps to give every frog and salamander a full body rub. Maybe we can hire migrants to do that job?

Well, this blows.

“The Expanse” to end on SyFy with Season 3, will be shopped elsewhere by Alcon

Apparently this has something to do with the distribution rights. The possibility exists that the show will be picked up by the likes of Amazon or Netflix.

Great. Just great. Lemme guess: it’ll be replaced with ghost hunters and rasslin’.

Fingers came into this house as an adult semi-wild rural farm cat, and as a result has never been what you’d call domesticated. She tolerates me well enough; on occasion she rubs up against me and even hops into my lap for *brief* scratchings, but she cannot abide any other human. She promptly hides if there’s a visitor or even a package left at the door, and when taken to the vet goes into a panicky frenzy. What she *did* like was Raedthinn.

I think I’ve made it pretty plain over the years that my cat Fingers *really* had a thing for Raedthinn. She was quite pushy with her physical affection for him… she wasn’t satisfied with laying next to him, she wanted to be on him, often kneading him. Many’s the time I was in the living room writing or CAD’ing when something would intrude into my consiousness and I’d come to and wonder “WTF is *that,*” then realize that it was the sound of Fingers purring at *extreme* volume several rooms away as Raedthinn deigned to give her attention, sometimes even licking her head. In those moments, she was joy personified. Something Fingers has never done is purr away from Raedthinn, except for a few rare instances when she hopped up on *me* and purred in response to head scratchings.

So I’ve been keeping a close eye on Fingers these past few days. I’ve been wondering just when it’ll hit her that Raethinn is gone, and what she’ll do when she figures out she’ll never see him again. Of course, does a cats mind even work that way? Does she remember him as a human would, or is Raedthinn only a vague concept in her little head? Does she understand the concept of “gone” and “never again?” It is of course impossible to say.

So… last night, it dawned on me that she was curled on on Raedthinns favorite corner of the bed. Purring.

She was in his spot, where he often hung out, which undoubtedly still carries his smell. Was she imagining that he was there? Was she purring in hopes that that would entice him to come back from wherever he’s hiding? Purring is often seen in badly injured cats; it’s thought that the action of purring releases dopamine to help ease pain. So perhaps she was purring as a way to grieve a loss she does not understand.

This is the first launch attempt of a Block 5 Falcon 9. Assuming SpaceX gets a few of these safely under their belt, they can use them to launch NASA crews to the ISS, finally putting the US back into the manned space launch business again. This launch is sending up the first Bangladeshi geosynchronous comsat. Launch is current scheduled for 3:47 PM, Mountain time, followed by a planned recovery of the first stage on a barge.

The Convair VL-3A was a 1966 concept for a space station logistics spacecraft. It was a sleek, flat-bottomed lifting body featuring a twin tail and flip-out wings that would deploy shortly before landing to reduce the landing speed. It would be fitted with flip-out turbofan engines for range extension, self-ferry and control during landing. General Dynamics released sizable “educational” cards with information and photos of models of the spaceplane showing how the wings would deploy from within the lower fuselage.

I have uploaded righ-rez scans of both sides of this poster-sized card to the 2018-05 APR Extras folder on Dropbox for APR Patrons at the $4 level and up.

I also wrote about and illustrated the VL-3A in US Spacecraft Projects #2, showing the general arrangement of the design along with the disposable propulsion stage and the launch configuration atop the Titan III.

USSP #02 can be downloaded as a PDF file for only $6:

If you are interested in thes VL-3A model images and a great many other “extras” and monthly aerospace history rewards, please sign up for the APR Patreon. What else are you going to spend $4 a month on?

Sometimes the jokes write themselves. And sometimes the thing itself is a joke, and no further commentary is necessary.

Practical Female Separatism for the Everywomon, in Easy Steps

Now, after saying that no commentary was necessary, I still wish to comment, because there are several obvious conclusions to draw from this… assuming that this nuttery gains *any* sort of traction and doesn’t remain the province of a wacky, irrelevant few:

  1. It would seem to be necessarily self-limited. It self-edits out of the gene pool; I don’t know how much of the nuttery involved here is genetic, but assuredly it has *some* basis, even if only tenuously. Do this long enough, and they will make themselves extinct along with the Angry Incels. Additionally, by separating out the wackos, those who remain in society will necessarily be those who *want* to remain in society, and they will reproduce more. Thus by both eugenics and culture, the non-nuts will outbreed the nuts.
  2. Where does this sort of thing come from? As recently mentioned in the comments hereabouts, there have long been stories about Devious Foreigners and Scary Space Aliens who wish to colonize America and/or Earth, but don’t want to got to the bother of wiping out the natives. So instead, the convince the natives – through propaganda, Social Justice screeching, chemicals in the air, water or food, or genetically modified retroviruses and the like – to stop breeding. Wait a few generations, and whoever is left will be few in numbers and old and infirm, easily toppled, while their infrastructure will remain in place. Are the Wimmin Separatists a truly modern creation? Are they the result of a long-dead Soviet effort? Some holdover from the Nazi era? Perhaps a devious scheme from the Han Dynasty?
  3. Don’t Date Robots!
  4. Who else gets the feeling that if you got a look at these “womon,” you wouldn’t *want* them to breed, particularly not with you?

Pointing and laughing at wackos like these does not erase the grief of losing Raedthinn. But at least it covers it up for a bit. He was a better human that any of these nutjobs, and was assuredly a better companion and conversationalist than any of them.
