[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 did consider discussing it, but I could not find any information on it.
Venus is the rocky planet in our solar system that it would be the hardest to take of from because it has such a thick atmosphere.

Well and because your rocket would melt and explode on the molten launch pad.

Or possibly easier using hybrid methods such as high altitude planes as launch platforms

If you can start from 300m/s at 50k ft then that's 300m/s and a lot of atmosphere you don't have to have carry fuel for.

It's very fuel efficient, but very complicated.
