The map was originally intended to be a Blitz Survival Games map for the Hypixel Network, so the project itself is around 400x400, with the height of about 200. The map was supposed to be seen from the ground, there for the surface of the map is actually within the crater where the rocket is. the rest above the crater/around it is just terraforming :)
Hopefully we'll be placing it on the creative server at some point very soon, so everyone will be able to run around it and explore for themselves!
