It’s interesting and I love seeing the “payload yeeter” start to actually get traction, but iirc there is downsides. It’s not like you can just launch any old thing, the payload needs to survive more Gs and it only replaces the first stage. So still need fuel and propulsion.

So many interesting “hype” things either get lost due to development, or not panning out. So it’s always great to see when they “succeed”.

Just this month they broke a 2 year silence.

That’s basically what spin launch did. They went and bought just consumer parts (not even the ones NASA could get/build) and put them into their centrifuge.

Cars get towed backwards all the time, it would detect that it’s traveling the same direction.

Modern soaps/detergents don’t contain lye, which is what ruins the seasoning. It’s the humid drying of a dishwasher that causes it to rust. Nothing to with the detergent.
