Mars colony by Space is More & Project Scorpio for Mars Colony Prize contest

This year The Mars Society is holding Mars Colony Prize - a contest for "the best plan for a Mars colony of 1000 people. The colony should be self-supporting to the maximum extent possible - i.e. relying on a minimum mass of imports from Earth. The goal is to have the colony be able to produce all the food, clothing, shelter, power, common consumer products, vehicles, and machines for 1000 people, with only the minimum number of key components, such as advanced electronics needing to be imported from Earth." Submissions for the contest are now closed and the winners will be chosen at the International Mars Society convention in Los Angeles, California in September 2019.

Here are images from the submission by the Polish team of Space is More & Project Scorpio.
