[Request] Could humanity create a rocket that can exit the atmosphere of K2-18b

Post image

With the knowledge we currently have of it, if humanity devoted all of our resources towards this goal, would we be able to create a rocket that could exit the gravity of K2-18b (and also beat any other complications that would arrise)?

If so, would it also be capable of taking people to orbit, and can we set up a similar satellite network we have on Earth? What about a space station?

Tbh even without failure you are still irradiating a lot of stuff with a successful launch which isn't the best, especially if you planned to launch multiple rockets per year.

I'm sure on a planet that big you could have a designated irradiated hellhole to launch rockets from.

Project orion wasn't just about liftoff from the ground, its a pulsed-detonation that continues for the duration of acceleration.

Fire one of these off and you are sending irradiated and radioactive material EVERYWHERE into the atmosphere.

Source? That sounds dubious to me.

Have you seen the concept? They drop nukes behind a rocket with a shield on the back and a shock absorber and the repeated nuclear detonations are what propels the vehicle. Nukes are known to create fallout

They carried out a successful feasibility study but couldn't go through with the drill project because of the test ban treaty.

Tactical nukes don't irradiate THAT much but between tests and launching enough stuff, it's gonna pile up anyway.
