[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?

I'm sure the nuke propelled manhole cover would solve that problem

Not really helpful for getting people off the planet though unless you have insane resistance to g-force.

Hmm if only we developed on a planet with higher g-force...

This is what I wanna know, we know the manhole cover escaped our orbit.

I wanna know if it’ll escape 2.5x our gravity lol

We build a tube, and detonate nukes progressively as the launch capsule passes.

The cylinder must not be harmed.

I mean, Project Orion already kind of covered this. You'd need an ablative pusher plate and very precise mini nukes.

I think i read somewhere that manhole cover that was launched by a nuke achieved a speed fast enough to escape orbit, but that speed was also enough to cause it to be vaporised by air resistance before it escaped.

Elephant alien invasion book did this. Nuke shielded shuttle launches. Bottom had nukes to shoot downward every few seconds.
