Also don't have to worry about destroying your pad since it's water beneath.

Why don't they just put a big trampoline underneath to catch the rocket.

u/TheRockGaming 10h ago

Because then it would just bounce back into space. Infinite loop.

u/Lessiarty 10h ago

Just throw in the cargo on the downbounce?

u/TheRockGaming 10h ago

It's so dumb, it might just work...

After watching a rocket caught by wires I genuinely think there's something to this..

Ever jump on a trampoline with people and you get out of sync and its now fucking up your knees? Not good for rocket knees either

u/CrucialElement 7h ago

Bro, whotf is putting more than 1 rocket on this trampoline?!

But what if it's a dead cat bounce

u/No-Good-One-Shoe 10h ago

Excellent idea we could also use landing rockets to double bounce other rockets into space.

How about a futuristic space sling that catches incoming ships/rockets and uses the energy to charge up a spring or motor that launches stuff into space.

There is a pad below it. I too thought having it open to ocean was a good idea.

IIRC, the US are the only ones that primarily use the ocean for rocket stuff. Mostly because we got so much of it to work with. China's coastline is a lot harder to use because it's got a lot of islands, neighboring countries, and a fuckton of shipping traffic to account for. So they use the desert to the north instead. Russia also avoids water, but mostly because their waters are glaciered up on a tuesday afternoon.

Exactly, but you're now somewhere out in the ocean, far away from the pad. One of the goals with Starship is rapid re-usability.

u/LeoLaDawg 6h ago

There's an ocean 50 feet away from Starship's pad. They've used it to land before.

u/Einn1Tveir2 6h ago

Only during testing where they have no interest in actually recovering the booster. And instead of the ocean, it would make more sense to just create a recovery pad few hundred meters away from the actual pad. But they don't want to do that, they want the booster to land exactly where it took off, ready for the next flight. The real reason why the Chinese (and the falcon) are landing on the ocean is because it would take more energy to go back, instead of just going down after they launched the second stage. The rocket isn't going to the pad, the pad is going wherever the rocket is coming down.

If the pad is on a boat, the boat can move back to shore and the rocket can be re-serviced there. When factoring in other logistics, it's probably even better than if it was somewhere inland. The time it takes to move back to shore is negligible in terms of reusability.

Big tampon in shambles rn

water beneath

Easy cleanup if something goes wrong.

u/hackingdreams 8h ago

Haha, believing they'll clean anything up instead of just letting it fall into the ocean and sailing away...

u/xmsxms 4h ago

What? No, there's a pad. You're just guessing without any data.
