Space Elevator, Kepler-22

Finished off another abandoned project - this one I originally started (so the Finder tells me) in July 2014.

As I have discussed elsewhere here and on dA, I grew up on the works of Arthur C Clarke, and so first encountered Space Elevators in The Fountains of Paradise (still have my copy!). Of course the concept was not even remotely new when ACC wrote about it; Konstantin Tsiolkovsky had beaten him to it by over 80 years. Space Elevators have become a common plot device - Iain M Banks ‘Feersum Endjinn’ is set in a crumbling, enormous State-sized city structure that includes a space elevator (referred to as the Tower or Fass(t) Tower). Ken Macleod’s ‘The Night Sessions’ has climactic scenes that take place on a space elevator (trying to avoid plot spoilers!).

At the end of Banks’ Feersum Edjinn there are descriptions of the top of space elevator - it features hotels, museums, sports facilities just like a modern airport… And that was the picture I had in my mind when I came design the space elevator. In particular, how like today’s airports, do you manage thousands of travellers? So, here are hotels, parks and so on. My design has an internal dock for small (inter-system?) ships, but larger interstellar ships dock at one of the four arms at the top of the elevator.

My space elevator - like Bank’s - is a compression structure; that is, a structure but from the ground up (as opposed to the cables-plus-counterweight structure generally now proposed). Why did I put it on Kepler-22? Kepler-22 is larger than Earth and therefore a greater gravitational mass, requiring a greater escape velocity (and therefore fuel) to get in to space. Using space elevators therefore makes sense.

The mesh is a bit of a kit-bash; the central components are the base mesh I used in Cities in The Sky and Colony Station. The “environmental supply & control systems” on some the arms were also used in Colony Station.

The living quarters - the discs around the central column - are a little in-joke… They started off looking a lot more like one of the famous 1950 UFO pictures that you find around the Internet… .

I borrowed quite a lot from other people for this too: the large circular frame is from “Low Earth Depot S1” by Ignus Fast, available at Foundation3D. The girdered arms and also “power generators” (the rectangular boxes) are from a sort of spaceship building kit called “Truss Pack” which is (I think) by Kenny Mitchell.

…and, of course, everything is greebled to death!

Texturing is extremely simple, being basically the hull and the girder textures, which are both mine - the hull colour is available in my resources gallery here on dA. The textures used in the hanger entrance at the top of the space elevator are by Dosch. FYI, the texture under the dome at the top of the space elevator is actually the architects impression of the recently cancelled Japanese Olympic Stadium ☺

The planet - Kepler-22 - was created using Michael Welters Atmosphere plug-in for C4D. It uses my own “Water World” texture (I know, there is a big continent there - in fact the texture has 3 Australia sized continents and lots of island chains). I used this mask from my DeviantArt Resources gallery here to create it.
