The Invisible Horror of The Shining

Good stuff.
Can Spinlaunch throw rockets into space?
maestro156 says...Yeah, 20000ft is roughly 6km. The air density is about 1/2 but from what I can determine that doesn't equal 1/2 air resistance, but something more like 90-95% air resistance of sea level.
Having said that, I haven't studied aerospace engineering, so I might be getting the details wrong.
There are definitely some minor advantages to building on a mountainside, but I don't think they outweigh logistical difficulties under normal circumstances.
The idea has a good bit of scifi (and probably scientific) history behind it though. I believe Heinlein used a railgun cargo launcher from the moon in Moon is a Harsh Mistress and a mountainside sled rocket in one of his earlier books.
Project Rho is a great resource for hard scifi and rocketry research for writers. http://www.projectrho.com/public_html/rocket/surfaceorbit.php is the link to a page that discusses maglev, railguns and rocketsleds.
I’m thinking Mt Chimborazo in Ecuador…at over 20000 ft, it’s peak it the farthest from the center of the earth (while not being the highest above sea level thanks to the equatorial bulge).
Sure, it doesn’t remove air resistance or friction, but halving it, even cutting it by 1/3 is a massive leap in efficiency and negates much of the extreme engineering and materials needed to overcome the friction….plus, as you mentioned, there’s the rotational speed advantage from launching on the equator vs Florida.
Also, while extremely minor, there’s also a slight reduction in gravitational pull at those heights. A joule saved is a joule earned!

StukaFox says...Wait -- she has eyebrows?! I guess I never got that far north on her. Also, you have great taste in late-70s TV SciFi babes!
I always wondered....If she can metamorph into anything, why does she still have lines of warts for eyebrows?
I'm hoping we freeze à la Buck Rogers, then maybe I can have my own Colonel Wilma Deering.
