Looks like they've finished you're mom's dildo.

Well played!
I'm all for packing spacespergers onto these things and ejecting them from the planet. They can watch Star Trek reruns while departing orbit.

>possible?
Technically, probably yes.
There isn't a working prototype yet, but the tech behind is well understood.
Economically, probably no.

stick an Orion drive on the bottom, pack it full of Sabatier and Bosch reactors, add in some hydroponics gear and frozen seeds, baby, you got a stew going!

A failure in the launch of such a behemoth would level everything in many miles

The whole thing would obviously not be launched at once. It'll probably be something similar to the ISS.

Serious question:
What are the technological challenges for building these spaceships in orbit, assuming we could gather all the necessary materials.
It should be much more efficient to build ships that are not designed to land at all.
Is this all just so much more complicated than my simple mind thinks it is?

?
It is the reusable second stage to their rocket
thats why its so big

Actually that's not even the whole thing, it's gonna sit on top of a booster, and it will be launched at once (how would you even assemble that thing in space?).

I think the main problems are that that would require a big initial investment, and that we have no experience with building stuff in vacuum or in microgravity. There are plans for superconducting magnetic guns that can fire stuff into space though, which would make transporting the raw materials for building the ship into space much cheaper, so building ships in space may become an economically sound thing one day.
