The clickbaity headline:

Star on collision course with solar system to bring MILLIONS of asteroids towards Earth

The less clickbaity details: the star in question, Gliese 710, is currently 64 lightyears away and won;t make its closest approach for another 1.35 million years. But here’s the interesting bit: closest approach will be 77 light *days,* with a possibility of 38 light days. The authors estimate that the passage of Gliese 710 through the Oort cloud will send a shower of comets into the inner solar system at a rate of about ten per year over a span of about 3 to 4 million years.

Sounds like it’ll be a hell of a show. Pity about the wait.

“We’re not in favor of the peaceful transition of power.”

 

Simply taking these people at their word would, in a rational world, squash the flawed stereotype that it is the Trumpists who are the violent ones. Sadly, this is a world where people actually give a damn about the Kardashians, so a rational world this ain’t.

Something I was surprised I didn’t see during the last election cycle: videos of these sort of people as part of major TV ad campaigns for the *pro* Trump side. Imagine the more unhinged elements of the Left spend the next four years throwing tantrums and firebombs, beating Trump supporters on the streets, torturing Trump supporters live on Facebook. What *better* advertisement could the Campaign to Re-Elect Trump possibly have?

The Aerospace Projects Review Patreon rewards for January will include a reasonably massive Douglas report on the Saturn V-launched pre-Skylab “Early Orbital Space Station” and a scan of a reasonably gigantic diagram of the Boeing 2707-300 SST. These will be released before the end of January and will be available to all then-current Patrons. So if these items interest you, and/or if you are interested in helping the effort to find and preserve this sort of aerospace history, be sure to check out the APR Patreon.

U.S. Navy F/A-18 Hornets released a swarm of 103 Perdix semi-autonomous drones in flight.

The Perdix drone is an itty-bitty thing with only 20 minutes duration, but it seems to be capable of some interesting things when released as a semi-autonomous swarm. The swarm of drones starts off as a line, but they end up orbiting a single target at a radius of about 100 meters. Beyond the direct military applications of data gathering, this sort of thing would likely be *seriously* disturbing to enemy forces. The end of the video is shot from that central point as a hundred screaming things circle it like a school of hungry piranha-banshee.

I caught “Hidden Figures” at the theater last Friday. Put simply: it’s a damn fine movie. Entertaining, well acted and uplifting. I understand some people see subtle hints of messages about race and gender in it, but what I saw was a fact-based story about three women who improve their own lots in life *and* make valuable contributions to society by not only hard work, but smart work in STEM fields. One is a mathematician, one an engineer, one a computer programmer (this was in an era when a “computer” was a person, someone who spent their days computing); all dedicated and skilled, and all working to put American astronauts into orbit.

The majority of the movie is set circa 1961 at NASA-Langley. It is thus *filled* with early 1960’s aerospace stuff… wind tunnels, adding machines, an early IBM computer that fills a room and requires boxloads of punch cards to program. Also included: lots of maps and plots and blueprints tacked to the wall of the Space Task Group room. Such as seen here:

See the two blueprints on the wall behind Kevin Costner? Those are Mercury capsule cyanotype blueprints I provided to the movies art department. Yay! This is, I think, the fourth time I’ve provided blueprints and diagrams to a movie or TV show to serve as props or set dressing; this is the first time where the scene didn’t get cut. So… huzzah! A few more of my blueprints appear in the flick, but these two were the standouts.

Now, if’n you’re like me, you’re an aerospace history nerd. Which means you pick movies apart like any other nerd, looking for the nitpicky continuity flaws (“Sulu wouldn’t push *that* button, he’d push *that* button!”). So, yeah, there are a few things that made the nitpicky nerd in me go “Heyyy…” A TV news reporter describing Alan Shepards first flight mentions that the sub-orbital Redstone rocket will go to “116 miles… per hour.” Shoulda stopped two words sooner, Ace. Though to be fair, it’s entirely possible that a reporter would flub their units like that. And in Al Harrisons (Kevin Costners) office, there are a number of bits of art, including a wooden display model of the C-5 Galaxy. Which would be a neat trick in 1961, given that the Galaxy wouldn’t be designed for another three years. Some stock footage of non-Redstone ballistic missiles going FOOM during testing, standing in for Redstone testing failures. And there’s a scene where Sheldon Cooper explains just what orbits are… to a room of NASA engineers who have been working on Mercury for a few years. Pretty sure they know what an orbit is. Of course, this scene was included not because it’s historically accurate, but because the *audience* might need to have the concept of an orbit explained to them (a damning indictment of the American edumacational system if ever there was one). But it still yoinked me right out of the moment.

But on the whole I found the movie to be terribly entertaining. The main characters are all well written and well acted, behaving with professionalism and dignity even when  faced with some serious dumbassery by their co-workers and their segregated environment. It’s the first non-Star Wars/Avengers/Lord of the Rings movie that I can recall where a sizable fraction of the audience applauded at the end. The special effects are relatively few; the movie doesn’t focus on the astronauts or the space flights, but on the people almost always forgotten in these stories: the engineers and mathematicians back on the ground whose work actually made the flight possible. But the effects that are included are pretty good and serve the movie well.

“By Dawn’s Early Light” was a made-for-HBO movie filmed and set just before the fall of the Soviet Union. In short, some PO’ed Soviet military jerks steal a Russian nuclear missile, sneak it into Turkey and launch it into Ukraine, sparking a limited nuclear war between Russia and NATO. Due to misunderstandings, mistakes, arrogance and bad leadership, a situation that’s already bad gets worse. While some of the effects are clearly dated, it remains an effectively creepy movie.

One scene that always freaks me right the hell out: the carrier (USS Midway) getting torpedoed and sinking. You don’t see it; it’s just radio messages. This shows an effective example of “less is more.” As there’s no chance that an HBO TV movie budget in 1990 would have been able to show the sinking of an aircraft carrier well, doing it off screen was the right choice.

Cities get nuked. Airplanes brought down. Presidents blinded. There is no happy ending. But at least James Earl Jones gets a real cigarette.

In short: a contact binary star system (KIC 9832227) 1800 lightyears away in Cygnus has been found to have a possible end-date. The period of the two stars in their mutual orbit has been decreasing (currently about 11 hours), meaning that the stars are spiraling in on each other. If the trend holds, in 2022 they’ll merge, and BLAMMO. This will produce a “red nova” which will be naked-eye visible, perhaps one of the brightest stars in the sky.
