As part of scientific work for a competition organized by the Mars Society, an American non-profit dedicated to exploring the Red Planet, architecture firm Abiboo has unveiled design concepts for a sustainable city on Mars. The project, called Nüwa, ranked as a finalist among 175 projects submitted from around the world for the 2020 competition. Abiboo presented the Nüwa proposal at the Mars Society convention in October, which was attended by Elon Musk from Space X, George Whitesides from Virgin Galactic and Jim Bridenstine from NASA.
