Never, in all my life, did I expect to see OPEC as the good guys. Yet here they are, trying to keep us from destroying the world economy through our obsession with carbon. Obviously they're doing it from self-interest, but that's okay. If more nations acted from enlightened self-interest instead of principle, the world would be a better place.

In the end, what's so incredibly frustrating about the 'global warming' people is their insistence on a prescriptive solution. Their goal *must* be accomplished through sacrifice, and no other way. They've borked suggestions for increasing global albedo through manipulating cloud cover, for using orbital reflectors (my personal favourite), and now for carbon capture.

https://www.researchgate.net/publication/351252619_Fungi_on_Mars_Evidence_of_Growth_and_Behavior_From_Sequential_Images

There comes a time (and I think it was reached back in 1976, honestly) when you have to invoke Occam's Razor. It's somewhat disconcerting to have one's image of a clean, dry Mars, lifeless for a million years, replaced by that of a mouldy, stinky Mars where puffballs grow on everything, but that seems to be what we have.

A few times a year of late, it seems, we have another indication that free water is much more common on Mars than we'd expected. While increased amounts of water favour solubility-based mineral processes, life is, in general, more efficient at scavenging and conserving water than is abiotic mineral growth. Something else I'd very much like to hear the abiotic faction address (or if they have, I've not heard of it) is how iron peroxide, which was positted as a rather remarkable explanation for Viking's rather remarkable tagged oxygen results, could exist in an environment wet enough to grow mineral excrescences?

Absolutely amazing numbers of local automobile accidents these past few weeks, to the point where I'm starting to be consciously cautious about the decisions I make while driving. Increasing numbers of people seem to be ignoring speed limits and traffic rules.

Watching the Crew Dragon launch. It's fascinating to me that everyone: astronauts, ground crew, etc, seems to have a personal tablet, large or small. It's a sign of the times. Those things were new just ten years ago, and now they're ubiquitious.

*****

I watched the Turkish GP this morning. I felt greatly sorry for Lance Stroll. It's pretty hard to avoid the conclusion that his crew chief cost him a podium, if not an actual win. I can understand the team's reasoning for wanting a second tire change at that point, but when there's dissent, I'd almost always rather see the driver get his way. I'm sure some discussions took place afterward. Stroll had driven a masterful race up to that point, and was holding his own against men with vastly more experience.

I now know, by association, my second person to have Covid-19: My mother's hairdresser's son. He's asymptomatic. I have yet to know anyone, other than by reputation, who's had it. I don't doubt that the situation is all serious and terrible and a public health emergency, etc., but it's very difficult to be much excited about it when it just doesn't seem to really affect anyone.

I've shaken hands with more men who've stood on the moon than I have met Covid-19 sufferers.

I've had a beer (and a sit-down chat) with more men who've held the one-lap speed record at Indianapolis than I have met Covid-19 sufferers.

I've met more people who've stood face-to-face with Adolf Hitler than I have Covid-19 sufferers.

The astronauts have capacitative fingers on their gloves, so they can use touch screens. At least one is using a tablet. The capsule looks way open and roomy. Everything is on the screens - no switches or dials. I tend to wonder what happens if the onboard computer locks up.

The Dragon has red and green navigation lights. You get a wonderful view from the ISS cameras as it backs away, with the little thrusters stuttering. All of the maneuver burns seem to be broken up into a series of bursts.

The Warsaw FD's new fire truck is orange and black. It's odd-looking, but quite attention-getting. Like most emergency vehicles these days, it's pretty much encrusted with LED flashers anyway. You can't overlook it.

The road repair crew all have LED bands surrounding their hardhats, which looks absolutely surreal at night, especially the first time you see it.

Geez Louise, Boris Johnson won in a landslide. 66/34. I was predicting 55/45, maybe 60/40 at the very outside. Hunt pretty well doomed himself by saying he was open to a Brexit delay, I think. You have no chance of getting a good deal without being ready to walk away from a bad one.

It's Ohio State Fair time already! The summer has flown past!

The online guide, such as it is, is slightly less useless than it's been for the past few years. They seem to be using some sort of canned scheduling software, which is awful.

It looks as though the new Cardinal Center has been renamed after that asshat Kasich :(

Someone with a sense of humour has renamed the old Machinery Building (an open-sided machinery shed, basically, which is always populated with people selling weird junk that're too cheap to get a stall in the Commercial Building) to be "The Shoppes at North Commercial".

There's only one wild bird show (Eagles, Hawks, Owls, and stuff) per day now. Or not - it varies by day, from as many as three, to as few as none. Weird.

India's gonna launch a lunar lander/orbiter pair tonight! The whole thing looks very much like a Titan/Centaur clone to me. If you look closely, they've even got those roll modifier tanks, one on each strap-on, and then apparently two on the core stage. There's even a shroud around the core engine mounts, and an openwork adapter between the main and the sustainer. I wonder if that's what those two little tanks on the core really are? That makes less sense the more I consider it. And, I wondered then if those were some sort of humongous ullage motors, but the Indian's core motors start a few seconds before SRB burnout just like a Titan/Centaur, so you'd not need that. Some kind of trajectory modifier to keep the used stage from falling on land? It's a mystery to me.

Good luck to them!

Woohoo! Mars lander made it down safely! For whatever reason, I have a strong tendency to anthropomorphize autonomous space equipment. In my mind, it's a brave little device, risking itself to gather information for Man, more Instrumentality than instrument.

That is an astonishing amount of dirt stuck to the lens protector, and some of it pretty big chunks too. You generally associate that with wet dirt. That's presumably what got kicked up by the engines at landing. Those are hydrazine monopropellant engines , with the fuel decomposing over a catalytic bed (rhodium? platinum?) instead of burning with an oxidizer, so there's no water in the exhaust - just nitrogen and ammonia.

One supposes that if the Viking science team's theory about iron peroxide existing at the surface of the Martian soil is correct (and I have honestly always considered it unlikely), then the hot ammonia is probably burning off to form water. The exhaust would have to be hot enough to start the reaction, yet not so hot that all the water gasses away. I can't find any data on the exhaust temperature of those thrusters, and I'm disinclined to try to do the enthalpic calculations myself, as someone will undoubtedly think all this out in far more detail than I, and post the numbers online in a day or two.

So, for the moment, the sticky dirt remains a fun anomaly that invites speculation.

*****

And, CubeSats on their way to deep space!


Edit: And, as someone pointed out in conversation elsewhere, if the lens protector dome is plastic, then dry dirt heated and kicked up by the exhaust might stick like that also.

UK is going to build a launch facility in northern Scotland That seems a questionable choice of locale to me, that far north, where you can't much benefit from the planet's rotation. Even Baikonur isn't that far off the equator. Still, Lockheed/Martin are involved, so...

They finally caught the guy that murdered April Tinsley those 30 years ago! They caught him the same way that the guy who killed Arlis Perry was caught a few weeks back - by comparing DNA samples to an online database. I don't know how big of a case this was outside of the upper midwest, but here it was huge. He not only raped and murdered the little girl, but made it abundantly clear that he had enjoyed it, and wasn't the least bit sorry. He amused himself by sending obscene messages to little girls (and I think perhaps a few boys too) about what he'd like to do to them. One can only imagine the effect upon one's psyche at that age. I think the only real doubt about the outcome here is whether he'll survive prison long enough to stand trial. I personally won't be too upset if someone saves Indiana the expense of a trial.

I keep expecting some lawyer to claim that it's unconstitutional to use DNA, since that wasn't an available technology at the time of the murder. The sad thing is that I can kind of see the 5th amendment applying there.

Just about time for someone to get clobbered by the Celestial Palace! The impact window seems to have pretty much stabilized on a median date of April 2nd or 3rd. It orbits between 42.7° north and south, and I'm at about 40° north, so that puts me in roughly the 1% impact band. London, ON is at the top of the orbital track, in about the 3% band, with Buffalo NY not much lower.

*****

Enormous coronal hole too! I'd not been aware of that. It's unlikely to heat the upper atmosphere enough to affect the impact date, though. If you're in Canada or the extreme northern US, it'll probably be a good few nights to see the aurora.

Blofeld's hollow volcano is erupting! You Only Live Twice, despite it's absolutely goofy-ass plot with logical holes you could drive a truck through, remains nonetheless one of my three favourite James Bond movies, with the other two being the much more logical Goldfinger, and Thunderball. You Only Live Twice has the best of the opening sequences, I think, with a catchy song (although it can't hold a candle to Shirley Bassey's snarling performance in Goldfinger) and the Japanese parasol motif. It just works very well for me. The conceit of the villain having his HQ inside a hollowed-out volcano is absolutely breathtaking (and I know by all the times it's been parodied I'm not the only one who reacted to that), plus the sequences where SPECTRE's spaceship engulfed the two capsules, and especially the Russian one with the cosmonaut on his tether, were absolutely haunting. It's all like something from 1940s radio drama. The whole thing is so engaging that I'm willing to completely overlook all the reasons this won't work.

*****

You know, were I a politician, and did I desire to be loved by all, Democrat and Republican alike, I'd propose the abolition of Daylight Savings Time.

And, on review, I find that it was the American astronaut whose tether (technically an umbilical, since it was a Gemini) was severed by the SPECTRE ship.

The Soviet capsule, while looking nothing like an actual one, was, IIRC, reasonably close to speculative picture of a Voshkod that was current at the time.

Interestingly, to me, is that my first reference for the word "umbilical" was to a Gemini spacewalker's umbilical. I didn't know it was a biological term until several years later

My kitchen sink clogged. I took myself to Meijer's, thinking to buy a plunger. Well, Meijer's had at least three different brands of plungers, in five different models, but each and every one of them was a toilet plunger, the sort with the cone-shaped bottom, which is useless for a sink, where you need the flat-bottomed design. Wal-Mart had two models only, but they carried both kinds - a toilet plunger and a sink plunger.

I wonder now if Meijer's is letting their suppliers decide what to put on the shelf. That used to always be a problem at this tiny little grocery store in Mentone (a tiny farm town where I used to live). They would have, say, three different brands of pizza, but because the store was tiny, they had only room for one variety of each brand. They had some sort of deal where the salesmen decided what to put out, and inevitably, they each put out something that was as close as possible to what their competitor was displaying, so that you had a "choice" among three different brands of rising-crust pepperoni pizza, say. It's hard to believe that it was being done from sheer perversoty since they wanted to sell stuff, but it certainly looked like it from a consumer standpoint.

Woohoo, Falcon Heavy! After decades, we have, finally, a true heavy-lifter once again! Twenty-seven engines all at once, though - that looks like something the Russians would do. I was half-expecting it to explode on the pad.

And now I wonder - if you can gang-launch three of those cores like that, why not seven?

And I love the Falcon logo too!

Voyager One's ACS thrusters finally wore out. So, they used the Trajectory Correction thrusters instead. The thing is, those hadn't been fired since 1980. They worked perfectly.

I have friends that weren't even born when those motors were last used.

That probe is nineteen and a half light hours out now. I remember when it crossed the heliopause, and you could dial a number and listen on the phone to the carrier tone from the little spaceship as it left the solar system.

So, now I'm back home from Memorial Day. I got to see Takuma Sato, one of my favourite drivers, win the Indianapolis Five Hundred, and hang out with mom for a few days as well.

*****

It's probably safe to say that Takuma Satop isn't one of this fellow's favourites. I think that on the one hand, it's sad that anyone would still feel resentful three-quarters of a century after the war*, but on the other hand, firing the man was IMHO an over-reaction.

* A war, moreover, in which we administered one of history's most comprehensive beatdowns since Carthage pissed off Rome, then completed our victory by rebuilding their society to be pro-American.

*****

At 5'5", Sato is apparently the shortest man to ever win the Five Hundred. Surprisingly, he's one of about six or so who won their first Five Hundred when they were over 40 years of age.

Delicious cherries and cold milk! Now we'll see if I'm harder to kill than Ol' Zachary Taylor.

When regarding the hundreds of thousands at the Speedway, I'm always reminded of Hannibal's statement before the battle of Cannae, as true today as it was then: "In all that vast host of men, there is not one named Gizgo".

Space-X static fires a Falcon Heavy core unit. I love Elon Musk's attitude: "One way or another, launch is guaranteed to be exciting".

I am disappointed in the Smithsonian. When you're converting the thrust to rotary motion, it's no longer a "jet". It's a turbine engine.
