Lunar lava tube has been confirmed.

WaPo: First lunar lava cave has been found.

WaPo: First lunar lava cave has been found.

My prior post about China looking at lunar lava caves referenced an article that didn’t have any new information about lunar lava caves.  This recent WaPo article announces the first direct evidence of a lunar lava cave.  There are a few similar news reports all based on this Radar evidence of cave conduit science article.  This science article has less fluff and more interesting information.  That link may not remain active, so I will post an interesting diagram from the article.

China is going to the Moon.

SpaceNews: China interested in lava tubes.

China, and anyone interested in a Moon base, should be interested in lava tubes.  If NASA does wake up, it’s likely to roll over and go back to sleep.  Fortunately, Elon Musk needs a Moon base to get to Mars.

The movie, 2001:  A Space Odyssey, got a lot right.  The surface of the Moon is an obnoxious place to live.  The surface temperature goes from about  -200o F to 200o F.   Gamma rays bombard the surface, but cosmic rays are a bigger problem.  Cosmic rays hitting the Earth produce the Northern Lights as their energy dissipates in the atmosphere and are deflected by our magnetic field.  Those subatomic particles moving at nearly the speed of light, are not easily screened

Consumer-grade exoskeleton.

Tech Crunch: Exoskeleton

The tech, called MO/GO, short for “mountain goat,” is a hybrid soft/rigid system designed to assist wearer mobility and boost the wearer while walking.

Pretty sure they came up with MO/GO first, then came up with the “mountain goat” explanation.  Still, it would help a lot of people if it works.

The launch cost of $4,500 will almost certainly restrict its use for the non-mobility limited.

Depending on the performance specifications of the actual product, this could be big.  It’s certainly cheaper than a knee replacement and is in the price range of mobility scooters.  The military would be interested, along with people who aren’t impaired, just not up t the challenge.
MO/GO isn’t a great name, I’d go with “kicking pants”.

Disney’s Star Wars hotel was never going to work.

Disney spent a quarter billion dollars to build, Star Wars:  Galactic Starcruiser hotel, and it only remained open for a year and a half.  This girl spent $6000 to be immersed in the experience.  Fortunately, she’s cute and made an engaging 4-hour video about her Star Wars adventure that’s been viewed by 7 million people.  She should recoup her expenses.

Disney is a big company, with a net profit of 1.7 billion dollars last year.  They can’t keep making big mistakes like this.  How did they screw this up so bad?

City Journal: Green Tech is a Fantasy.

City Journal: Politics and Physics Collide

The legislature and unelected regulators enjoy magical thinking because the time frames are long, they will never be held responsible and perhaps engineers can meet the goals.  Automakers have long been burdened with fleet economy standards that must be met.  The Laws of Thermodynamics are problems for engineers, not legislators.  Cars became lighter and less safe while also becoming more complex and expensive.

The idea that the United States can quickly “transition” away from hydrocarbons—the energy sources primarily used today—to a future dominated by so-called green technologies has become one of the central political divides of our time.

WSJ: Why Does Elon Musk Keep Talking About Merit?

WSJ: Elon Musk on Woke Mind Virus

WSJ: Elon Musk on Woke Mind Virus

For months and months, the world’s richest man has been talking about the “woke mind virus”—let’s call it WMV for short. He describes it as a threat to “modern civilization” and says those concerns motivated his decision more than a year ago to buy the social-media platform now known as X.

Musk is the richest person in the world and with Tesla and SpaceX, owns two companies that dominate their highly technical market sectors.  He also owns companies that may be critical to the future in the fields of boring tunnels, artificial intelligence and a brain/computer interface.  Since Musk is bringing us the future more than anyone else on Earth, it may be worth trying to comprehend his message.

When it comes to how he defines that threat, however, he has been vague in public—painting a picture of something akin to hysterical groupthink by liberals against merit-based achievement and free speech, a catchall for what he expresses disagreement with.

That seem pretty clear.  While a few large investment companies, corporate media and politicians are banging on about diversity, inclusion and equity, it may be worth asking where they see DIE taking Western democracies.

With recent congressional testimony and charges of plagiarism against the current president of Harvard, it seems obvious that she is a diversity hire with scant accomplishments to be account for her lofty position.  How much of the rest of our institutions are led by unqualified people who are above accountability?

Musk is arguing for merit in judging applicants and with his obvious success, it’s worth considering his opinion.
