Today, the notion of building a space launch system that uses solid rocket boosters is kinda… silly. Liquids have much higher performance and, as SpaceX has conclusively demonstrated, liquids are quite recoverable and reusable, far easier than solids. But fifty, sixty years ago, solids made a *lot* of sense. They worked, they were reliable, they did not require a whole lot of delicate , constant babying. And for military purposes, they were (and remain) fantastically useful; load them up, stick them in a tube, forget about them for a few years, fire them at a moments notice.

This piece of Aerojet artwork dates from 1961 at the latest and depicts a large solid rocket booster, presumably for space launch. The diameter was 288 inches… larger than the largest actually-tested solid rocket motor at 260″, smaller than the 396″ diameter of the Saturn V (also the diameter of the largest solid rocket motor design I can recall seeing). Note that it uses four nozzles. This is not uncommon on military solids such as the first and second stages of the Minuteman and some sea launched ballistic missiles; it’s costlier and weighs more than a single nozzle, but it give you the same performance at a shorter length. And when your missile is stuffed into a silo or, worse, a submarine, compactness is important. but those missiles all also constrain the maximum dimensions of the nozzle assemblies to be no greater than the motors they are attached to… again, so the missile can fit in a tube. THIS design went another way, with nozzles well outboard. This precludes silo launch. The advantage for a non-silo launched space booster to split up the nozzles like this is unclear. Some small reduction in total length, and some roll control authority.

Vaguely related: US Bomber Projects #17 has an article and diagrams of a somewhat smaller 260″ diameter solid rocket boosted ICBM from Thiokol.

Staircases in Space: Why Are Places in Science Fiction Not Wheelchair-Accessible?

Ho. Lee. She. It.

The author spends the entire article complaining that the Enterprise and the Millenium Falcon aren’t wheelchair accessible. You know, the Enterprise set in the universe where transporters can simply beam infectious diseases out of you. The Falcon from the universe where you can get a limb hacked off and get a fully functional robot replacement in an *hour.* Or even three limbs. The author, after noting that Star Trek is set in a future that is utopian, actually writes this:

Contrary to ableist opinion, a utopia is not a world where disability is a problem that’s been solved; rather, it’s an inevitable expression of genetic variance, and disabled humans are not just welcomed but fully included.

In *any* sort of substantially more advanced future, disabled humans would be accepted by being made ABLED.

Why don’t we see people trundling around the Enterprise in a wheelchair? Because Bones fixed their little problem, and now they’re strolling the hallways, not taking up space and being inefficient. heck look at Geordi Laforge: born blind, they didn’t rebuild the world to make it easier for him to navigate it as a blind man… they gave him new friggen eyes and now he can see better’n anybody.

I have been writing my own science fiction. I’ve been writing a *lot,* perhaps (from an rational economic standpoint) too much. In any event, most of my writing takes place in a world hundreds of years down the line. It’s by no means a utopia, but the technology is in may ways inconceivably advanced… to the point where there are a whole lot of present-day identitarians would be appalled to discovered that they simply wouldn’t exist there. You won’t find anyone with Downs Syndrome. People without limbs due to genetic flaws have their genes brought back up to code, generally before birth. People who lose limbs are given options… robolimbs, printed biolimbs which are simply plugged in, or regrowing limbs in-situ (each has advantages and disadvantages). The blind can see, the deaf can hear, the disabled made abled.

Some people in the present world are in wheelchairs because of problems they’ve had from birth. The author of the piece, for instance, seems to have a lifelong issue that eventually resulted in the need for the chair. Other people wind up in wheelchairs because of accidents. I suspect that very few people in the latter category are happier in the chair; most – perhaps, statistically, effectively all – would prefer to be brought back to factory fresh condition if possible. In most sci-fi futures, that would be possible, perhaps even trivially so. For the people in the former category, I guess I can kinda see where they come from if they’ve developed a “Disabled Identity:” they’ve lived with this their whole lives, it’s an integral part of who they are. But in that sci-fi future… that little quirk in who they are would have been corrected when they were a baby, a fetus, perhaps even during the process of artificial insemination.

There is a third category: not those born to disabilities, not those who get there via misfortune: those who *want* to be disabled. There are people who would rather be paralyzed or have a limb amputated, because in their minds eye, that’s who they really are. Well… in most sci-fi futures, they can fix crazy, too.

The author even complains about the ships from The Expanse as being wheelchair inaccessible. Well…on the one hand, they are pretty much Everybody Inaccessible during high-g burns: you sit there and take it. And on the other hand, in season 3 we actually see a character become disabled, her skeleton and internal organs squished by heavy machinery. And how did they respond? Did they make the ship Handicapped Accessible? Nope. Robolegs.

And doubtless in season 4 the character will be fixed good as new and won’t need the exoskeleton anymore.

Interestingly, I didn’t catch anything in the article about Fat Acceptance. Given how bloated Americans have become in the last few decades, if the trend continues Will Riker would be the size of Jabba the Hutt. but in most sci-fi, there are exceedingly few people who are Pleasingly Plump or Plus Sized; the vast majority are Standard Healthy, with the occasional Really Fat Guy there, generally as an alien or a bad guy. The reason for this is, again, perfectly cromulent: in the future, fatness can be dealt with relatively easily. I imagine there’ll be nanites that will give you liposuction from the inside. Food that you can eat by the ton with no calories or carbs. Muscles you can grow to order. There’ll be no need for fat, so the only folks who would be fat are those who *want* to be fat. Since most people ant to be attractive, the truly overweight will be a rarity; and the rarer they get, the more odd they will seem… and that will make them rarer still. Tere will doubtless be fads that come and go for body modifications… tails, pointed ears, blue skin, fur, extra limbs, you name it.But one thing that will very likely stay niche is a body that is broken and handicapped. In contrast, I expect something of an arms race to be hyper-capable. In a sci-fi future where genetic engineering and cybernetics can make any man Superman… who would choose a wheelchair?

I’m still debating whether or not to proceed with t-shirts. In part because I’m lazy, but mostly because I’m neither artistically inclined nor do I think I’m all that witty. Certainly not at this level.

slightlywrong

They specialize in pop culture references that are, as might be guessed, slightly wrong. Anyone who has known superfans knows that getting things *slightly* wrong will drive them/us bonkers.

 

Some years ago, for about thirty seconds a meme was popular that spliced together a photo of a pop culture character, together with a quote from another, and an attribution to a third. It was exactly the sort of thing that would cause the autistic/OCD aspects of nerddom to flip.

This is the generation that wants socialism.

‘Hot Water Challenge’ reportedly leaves teen with second-degree burns

Swallowing Tide Pods, snorting condoms, supporting Democratic Socialists, now they’re pouring boiling hot water on each other. Are aliens beaming bozo rays into kids heads or something, convincing them to do things that are *obviously* self-destructive and stupid, even to children, in order to wipe out the human species? Or just to weaken American civilization enough so that when hordes of “migrants” come swooping down from the stars we won’t have the wherewithal to keep them out?

Bernie Sanders’ ‘Medicare for all’ bill estimated to cost $32.6T, new study says

That’s $32.6 trillion dollars over ten years, or $3.26 trillion dollars per year. Estimated 2018 US Fed Guv revenues are $3.34 trillion. Estimated deficit is $833 Billion… *before* you tack on an extra $3.26 Trillion.

Current US population is about 326 million. That extra cost works out to $10,000 per person per year. But since something like 40% of the working population doesn’t pay federal income taxes, and a whole lot of people are children and the retired and such… well, I can’t be bothered to do the math, bit I’m thinking it works out to a wee bit more than $20K per taxpayer per year. On top of all the taxes *already* owed.

Update… Oh,FFS:

Clade X: A Mock, Yet Entirely Plausible, Pandemic

Seems I got snookered by 2018-level journalism.


Clade X virus can kill 900 million people across globe if not checked, says study

This bit is a little bit of a head-scratcher:

Clade X virus could be the next pandemic scare and the world is not prepared to face it, showed studies conducted by the Johns Hopkins Center for Health Security. With no vaccination and no drugs to cure it yet, Clade X can kill 900 million people across the globe covering about 10% of the world’s population.

Ummm… current planetary population is about 7.6 billion. If the disease covers 10% of the population – 760 million – and kills 900 million, that would seem to indicate it can kill people who don’t even have it. Woo.

But aside from the clumsy description, Clade X seems to be a fabulous little killer, spread by coughing. Woo.

In  rational world, there’s no way this cop gets out of this with his career intact. Or with his career, period.

Some colorful metaphors are energetically deployed in this video, in a manner that seems not at all inappropriate.

If you’ve looked into the front of a modern American police car anytime in the last 25 years or so, you’ll recognize that they are filled, nay, overfilled with technology. I’ve always thought it was kinda bugnuts that the driver of a police car had access to a fricken’ laptop while driving.  And even with all the electronical attention-destroying technojunk he already had, this guy thought it was  a good idea to be looking at his phone while not only driving but also while taking a corner. He has been suspended. Note that the police vehicle has a dashcam… that should prove to be interesting footage, with one very startled looking bicyclist.

Sooner or later self-driving cars will make it into the police force. It’ll be interesting to see how long it takes for self-driving police cars to be *better* at high speed pursuits than manual cars… freeing up the driver to shoot the bad guys while on the move.

Interestingly, take a look at the bikers YouTube videos… they are *filled* with prior vids of him seeing cars where the drivers are busy texting and whatnot.

Social justice warriors will try to ruin *everything* good in life. Behold:

Celebrate the 40th Anniversary of ‘Animal House’ by Tossing It in the Trash

Basically, “Animal House” is politically incorrect, problematic, insufficiently feminist and woke. Just wait until they remember “Revenge Of The Nerds.”

These people will be the death of civilization.

Here’s your fabulously ignint news article for today (yeah, yeah, it’s from more than a week ago. You want more timely blogging… gimme money):

Sen. Chuck Schumer warns of coming online blueprints for ‘ghost guns’

Media proves how good they are at their job:

As of Aug. 1, websites will be allowed to post blueprints explaining how to make so-called “ghost guns” — guns manufactured on 3-D printers, and able to pass through metal detectors unseen because they are made of plastic.

It’s good to know that the springs and firing pins and barrels and bullets and cartridges will all be made of special metal-detector defeating metals.

Senator Chuck Schumer proves how good he is at his job:

“I am sounding an alarm that come Aug. 1, America is going to get a lot less safe when it comes to the gut-wrenching epidemic of gun violence,” Schumer said. “Ghost guns are not only scary, they’re outright dangerous in the way they can mimic the look and the capacity of a hardened, fully semiautomatic weapon.”

Schumer says three stupid things:

1) August first, just a few days now, we’ll see a statistically meaningful increase in violent crime due to the sudden availability of 3D CAD models.

2) “Ghost guns are scary.” If you’re Scooby Doo, maybe. If you realize that a “ghost gun” is a more expensive and complex product for a criminal than simply *stealing* a gun, then, not so much.

3) Fully Semiautomatic Weapons. FULLY SEMIAUTOMATIC WEAPONS. FULLY SEMIAUTOMATIC WEAPONS.

Looking through ebay tonight I found a seller with a 1981 issue of a stamp issued in the island nation of Comoros, commemorating approach and landing tests of the Space Shuttle Enterprise. There have been a *lot* of spaceflight related stamps issued by dinky little nations; my assumption has always been that this is a reasonable and understandable way for these small countries to make a little scratch from foreign stamp collectors, rather than as a way to mail letter.

Anyway, this particular stamp comes still attached to a souvenir sheet. Additional artwork on the sheet includes the starship Enterprise (linking it to the Shuttle), a Boeing X-20 Dyna Soar, which I’m a little surprised they were even aware of, and a portrait of Austrian rocket engineer/scientist Eugen Sanger, who died in the 1960’s. An unusual bunch to see together.
