So, the idea is to use a presurized Cybertruck as a, I assume manned, rover on mars in 2025. So there will be a manned mission to mars in 2025 supposedly conducted by SpaceX. Otherwise the economics of using something as large and heavy as a Cybertruck is just not feasible.
With Tesla's work on autodriving capabilities, I'm kind of hoping this might be Musk's personal R/C car on Mars as an unmanned rover concept before humans get there.
One thing that puzzles me, and that is also a big reason for me being sceptical towards Musk, is that almost of his ideas are stuff I phantasized about in my teens because they were "cool". But with all cool things from your teens, they turn ridiculous when you grow up. And unprofessional in the industries SpaceX and Tesla are in. A remote controlled Cybertruck on Mars? Technically already now feasible but expensive and pointless to get there. Not sure what Musk being able to finance all that is good thing.
If something is both immaturely "cool", and immensely practical/ecofriendly/a good choice, we can all fulfill our childhood dreams while being responsible adults. Fart mode in the Tesla is a good example. Hilarious, stupid, and in some of the best and eco-friendliest cars ever.
And stuff like that just so kills Tesla for me. All that late stuff that came after, say, Model S or at least Model 3 looks more like Musks version of buying a Porsche convertible aged 45.
And you're probably the wrong demographic. I'm 18 and taking delivery of my Model S on Monday, because I can't afford the roadster and it's not out yet. Tesla is simply the future, and it's on a roll right now.
> The Marree Man geoglyph depicts a man holding either a woomera (a throwing stick once used to disperse small flocks of birds) or a boomerang (but see Plaque section below).
That's not exactly the description I would go with for a woomera. The woomera is not thrown, and acts as an extension of the arm when throwing a spear. A boomerang is more likely to be used for flocks of birds, so the definitions may have been mixed up.
People might know it better as an _atlatl_. Generically, it’s a “spear-thrower”. It’s amazing how much difference they make - good fun to make in the backyard!

I am not a mechanical engineer.
My understanding is that some composite materials used in modern aircraft manufacturing can fail in ways unlike classic aircraft aluminum (i.e. suddenly, without prior visible signs of stress/wear).
I am a mechanical engineer, and yes it is. The composites are simply too new to have all their properties adequately modelled yet. And they are a moving target.
