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)

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.

The video helped..thanks.

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?

For people? Yeah. No.
Here's a few numbers...

Yeah, roughly 1000 times what the human body can tolerate.

You would turn to mush before you ever got launched.

Just imagine the mess when there's an issue with the release and the projectile does not go out the exit.

:D a bit.

^^^ 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.:)

Didn’t David use one of those things on Goliath?

^^^ He was years ahead of his time!
He's the ceo of SpinLaunch now.

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

He didn't specify alive.

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.

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.

This vid addresses that question...(at about the 8 min. mark)

it was in the Cool Science Story Of The Day [Continuing Thread]

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