Toronto plane crash.

Reuters: Plane flips over in Toronto

Maybe it will come out later, but where is the video of the plane flipping over?  Airports must have cameras all over the place.  I’ve flown on plenty of Bombardier CRJ jets on the feeder airlines.  I didn’t like it so much.  While landing, the runway looks like it’s swinging back and forth like a pendulum.  The pilot aspires to touch down at the bottom of the arc.  So far, the brisk wind is suggested as a cause.

In a way, this crash inspires confidence.  There were 80 people onboard, and no deaths or life-threatening injuries.  Just getting people out of the inverted seats could be the cause of several injuries.  That is a sturdy little jet.

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?
