SpinLaunch
I had never heard of this before now.
I wonder if it could be used for launching a human? (it doesn't seem possible) https://techcrunch.com/2021/11/09/spinlaunch-completes-first-prototype-flight-using-kinetic-launch-system/

I suspect that might be a bit much stress for humans.

It would surely make satellite launches less expensive.

Some of the first Science Fiction stories had man going to the moon, launched from a canon.
If the energy needed to slingshot or "spin" it into orbit is less than using a rocket, lots of thinks can be put in orbit. It will still take a lot of energy to get it spinning fast enough to be orbital.

Ahh! This explains it better. I wasn't picturing that type of launch.

What?
|
Sure doesn't seem feasible. Could this possibly be scaled up enough to launch a craft like the James Webb telescope, a Volkswagen sized rover?

^^^ Yeah, if the timing on the release was wrong....could cost big bucks at that speed.
The spinner even has a tractor rain-cap on it.

One more vid from youtube.....Almost like a science fiction movie!
And to think they could do a few each day would be amazing.

Question, so this uses a counter weight so it doesn't get out of balance. What happens when it let the cargo loose? Counterbalance go away too, or does it stop real quick?

Every time I look at that thing all I can think of is this.
https://people.com/travel/worlds-most-dangerous-waterparks-grisly-secrets-revealed-in-new-documentary/ And yes, if you've seen the documentary and were not fortunate enough to be a teen in the area during its heyday every bit of it is true. It's amazing more people didn't die but we loved it.

I like Spinlaunch. All sorts of interesting issues to overcome but seems feasible.
