Re:SpinLaunch completes first test flight with rocket-flingi... by neltnerb on Saturday November 13, 2021 @12:09AM (#29207570)
Yeah, I didn't see any explanation for that either. With that much kinetic energy around I wonder if it's designed to simultaneously launch a portion of the counterweight.

It's got a lower lever so the overall momentum might be low enough to make that recoverable. Maybe if it's 10% of the rocket's momentum, going into... yeah, it's hard to imagine that being recoverable but maybe it's just weights and that's good enough.

I'd love to see a real explanation.
