An evening pause: Hat tip Jim Mallamace, who accurately describes this as “a mildly amusing short sci-fi film.”
My thought in watching this short film is that I have been watching and reading sci-fi movies and books about a oppressive future imposed by technology for almost sixty years. All were written as warnings of a future to avoid. Instead, it appears we have taken them all as instruction manuals.
The corruption of modern science and our intellectual class was well illustrated today by the following headline and article in the peer review journal Science:
Act now, wait for perfect evidence later, says ‘high priestess’ of U.K. COVID-19 masking campaign
From the article’s lead:
In May, when several prominent U.K. scientists pushed back against a Royal Society report recommending face masks to help control the spread of COVID-19, Trisha Greenhalgh was furious. The scientists argued there was insufficient support in the scientific literature for the efficacy of masks, and the U.K. government, following their lead, declined to mandate masks for the general public.
“The search for perfect evidence may be the enemy of good policy,” Greenhalgh, a physician and expert in health care delivery at the University of Oxford, fumed in the Boston Review. “As with parachutes for jumping out of airplanes, it is time to act without waiting for randomized controlled trial evidence.” [emphasis mine]
The highlighted words have been the typical argument of the global warming crowd for decades. “We can’t wait for evidence! We need to act now before it’s too late!”
Moreover, she — along with the writer of this Science article — also copies another global warming dishonest tactic, posing a false argument by claiming that the opposing scientists requried a “randomized controlled trial” to demonstrate the usefulness of masks. This is an absurd misstatement, as it ignores decades of research that already exists and was referenced by those opposing scientists, that showed that mandating widespread mask use was generally a bad idea, and would accomplish nothing good.

The new colonial movement: China’s Chang’e-4 lander and Yutu-2 rover have both been reactivated for their 23rd lunar day on far side of the Moon.
Yutu 2 is set to continue its journey northwest from the landing site and will target a roughly 12-inch (30 centimeters) rock on the rim of a nearby crater for analysis with a spectrometer. The rover has used that instrument to analyze a range of specimens in Von Kármán crater, notably causing a stir when it discovered an impact melt breccia initially described as “gel-like.”
It is the hope of the Chinese scientists that this rock will be ejected material from that crater and will have come from the lunar interior.
Also, though you need to read Chinese to understand how to access it, the project has released to the public another batch of data from both spacecraft.
Capitalism in space: ArianeGroup, the joint private partnership that is building Europe’s new Ariane 6 rocket, has successfully completed all testing of the three different engines the rocket will use.
The first stage has a core engine with side strap-on solid rocket motors, while the upper stage has a different engine entirely. All three have now passed qualification tests, allowing full design and construction of the rocket itself.
Capitalism in space: Apparently workers dismantling the old launch tower at Firefliy’s new launchpad at Vandenberg started a fire that burned the tower down.
A photo showing the former Delta II rocket’s Space Launch Complex-2 facility with flames and a huge column of black smoke rising from the distinctive blue tower began circulating on social media sites on Thursday night.
The launch site, most recently used for liftoffs of United Launch Alliance’s Delta II rockets, has been handed over to Texas-based Firefly Aerospace, which is developing a new family of rockets as an economical way to carry small- to medium-sized satellites into space.
The firm has a long-term lease to use the site with hopes of saving money by using some of the existing facilities. Firefly has plans to dismantle the historic tower, and a contractor armed with welding equipment reportedly sparked the blaze Thursday.
No word yet on whether this fire will delay Firefly’s planned first launch in the spring.
Not good news: According the Russian news source TASS, Russian astronauts have pinpointed the location of the slow leak on ISS to ” a fracture in the intersection compartment of the Russian Zvezda module.”
The astronaut also called it a “scratch,” which means the fracture is not yet confirmed. They will do more testing to find out if this is the leak source in the coming days.
If it is a fracture, the ramifications could be very serious. It appears the “intersection compartment” is the area where the aft docking port is located, which is also the area where many Progress freighters have docked in the twenty years since Zvezda was launched. Thus, this could be a stress fracture that can only get bigger with time. Its location might also preclude further dockings at this port, limiting arrivals of future Progress cargo ships.
Fun fact: They pinpointed this location using a floating tea bag.
The tea bag’s sway in zero gravity conditions towards the air leak overboard the space station was registered by cameras, the cosmonaut said. “We believe that we have really identified the probable leakage area. We have distributed a tea bag [in the Zvezda module] before closing the transfer chamber,” Ivanishin said.
The tea bag’s movement was recorded, the Russian cosmonaut said.

An update today on the mole digging tool on the Mars lander InSight has revealed that the mole appears to finally be completely buried, though it remains unclear whether its most recent digging effort had succeeded in digging downward.
We found that during the first two rounds of hammering and during the first half of the third round of hammering, the scoop went further into the sand. Since the Mole was hidden under the scoop, the penetration of the probe itself could not be observed directly.
During the hammering, the flat tether running to the probe moved considerably, but these could only be clearly identified as forward movements during the hammering on 22 August. Overall, we could estimate from the movements of the scoop that the Mole moved at most one centimetre further into the ground. It was interesting to observe that during the second half of the round of 250 hammer blows on 19 September, the scoop did not go any further, probably because it encountered duricrust. This was certainly a desired outcome, as it allowed a second Free Mole Test to be conducted. In fact, the probe continued to move according to the movements of the tether, but it could not be clearly determined that these movements brought the Mole deeper into the ground.
The image shows InSight’s arm above the filled hole, with the mole’s flat tether coming out of the ground.
They are now going to fill the hole more, and then press down with the scoop during later drilling efforts to see if this allows the mole to proceed downward. If it fails I’m not sure if there is anything else they will be able to do to get the mole to work.
Follow-up observations of the two big pieces of space junk, a Soviet-era defunct satellite and a Chinese upper stage, that had a high chance of colliding yesterday has confirmed that no collision occurred.
Shortly after the time of probable collision, the CZ-4C stage passed over the Kiwi Space radar tracking station in New Zealand. According to LeoLabs, “Shortly after [time of probable collision], we will have a direct pass of CZ-4C R/B over our Kiwi Space Radar in New Zealand. We have scheduled a search mode scan during this time to ensure we only see two objects as expected and hopefully confirm that no new debris is detected.”
This is exactly what happened, with the only observed object being the single CZ-4C stage — indicating no collision had occurred.
It is fortunate nothing happened. Though the collision point was about 360 miles higher than the orbit of ISS, the debris from a collision would have been flung in all directions, some of which might have crossed the space station’s path.
An evening pause: For the younger audiences, Ryan played Granny Clampett on the silly 1960s TV show, The Beverly Hillbillies.
The song is fun, but I just can’t get that vision of her incompatibility with her boyfriend out of my head.

New research into the air filtration systems on commercial passenger jets has found that it is almost impossible to contract COVID-19 while on an airplane.
A new military-led study unveiled Thursday shows there is a low risk for passengers traveling aboard large commercial aircraft to contract an airborne virus such as COVID-19 — and it doesn’t matter where they sit on the airplane.
Researchers concluded that because of sophisticated air particle filtration and ventilation systems on board the Boeing 767-300 and 777-200 aircraft — the planes tested for the study — airborne particles within the cabin have a very short lifespan, according to defense officials with U.S. Transportation Command, the Defense Advanced Research Project Agency (DARPA) and Air Mobility Command, which spearheaded the study.
You can read the report [pdf] here. I especially like this quote from their conclusions:
For the 777 and 767, at 100% seating capacity transmission model calculations with a 4,000 viruses/hour shedding rate and 1,000 virus infectious dose show a minimum 54 flight hours required to produce inflight infection from aerosol transmission.
In other words, you can fly around the world more than twice on the same plane, without stopping, without any real risk of getting infected.
Need I add that the use of a mask will likely make no difference either, while probably increasing your chances of catching some disease simply because the long term use of any single mask is unsanitary and almost guarantees it will be carrying pathogens on your face where you breathe?

No, today’s cool image is not a variation of the absurd “face on Mars” that our alien-obssessed fantasy culture focused on for more than twenty years that turned out to be nothing more than a mesa whose shadows in one image made it look very vaguely like a face.
Instead, today’s cool image is of a very weird Martian geological feature that strongly resembles the whorls and curls seen in all fingerprints, and is thus apply named “Fingerprint Terrain.”
The photo to the right, rotated, cropped, reduced, and annotated to post here, was taken by the high resolution camera on Mars Reconnaissance Orbiter on August 26, 2020. It shows part of the surface of Mars’ south pole residual icecap, about 130 miles from the south pole, at a place where the temporary thin dry ice mantle that arrives every winter with the bulk of it sublimating away with the coming of spring.
The fingerprint in this image shows that sublimation process, with the gaps in dry ice mantle getting wider and larger as you move north, until the ridges between disappear altogether.
But why does it look as it does, like a fingerprint? In other places this sublimation process does not look like this at all. Sometimes we get spiderlike formations. Sometimes we get splatters that suggest geysers. Sometimes the surface sublimates to produce swiss cheese shapes. But why a fingerprint here?
I asked this question of Shane Byrne of the Lunar and Planetary Lab University of Arizona, who had requested this particular image, hoping he and other planetary scientists had investigated this geology and come up with an explanation. His answer illustrates how little we yet know about Mars.
It’s almost definitely some sort of sublimation process, but it hasn’t been well investigated. There are some papers that talk about sublimation landforms on the cap in general and map out where different types are, but nothing that I know that’s specific to the fingerprint terrain.
In other words, why the dry ice cap sublimates away in this manner, at this and other locations, remains unexplained.
I’ll say it again: Mars is strange, Mars is alien, and Mars is therefore a place humans must go.
An event happened yesterday in our home that I think illustrates forcefully why no one can trust any poll being conducted during this election season.
The phone rings. As I now do on all calls, I pick it up, say “Hello?” and wait to see if it is a live person on the other end. If it is a recording of any kind, spam, political, poll, whatever, I immediately hang up. My life is too short to waste on robots or crooks. (I should add that if Diane picks up she does the same, though she doesn’t even offer them a “Hello.” She also often screens calls with caller ID, and thus often does not even bother to pick up.)
Sadly, a large majority of all in-coming phone calls now are from these robots, with the political and pollster robocalls coming more and more frequently, sometimes ten to twenty times a day.
If it is a live person, I listen to find out what they are calling about. If the call is for a commercial product or a scam, I tell them to stop calling us and hang up.
If it is a from a political campaign office or a survey I also say I am not interested in talking, and say good-bye. If the call is from a survey but specifically asks for my wife, I tell her about the call so she can decide what to do.
This happened yesterday. Her answer: “Please tell them to go away.” I then told the guy on the line her exact words, adding that I agree entirely with her. He laughed, and said good-bye, ending the call.
A lot of political experts have wondered whether the refusal of shy Trump voters to answer poll questions might be skewing the poll totals in favor of Biden and the Democrats. This may be so, but I think something more fundamental is happening that makes all poll results untrustworthy.
