Mankind has come close to solving the issue of interplanetary flights and the further colonization of extraterrestrial worlds. In the coming years, we are promised that the regular movement of spacecraft to Mars will begin. Space colonialists will need reliable and durable autonomous houses that can endure all the trials on the red planet. Since 2015, NASA launched the full-fledged 3D-Printed Habitat Challenge contest, which aimed to demonstrate the design, architecture and technical equipment of homes for Martian pioneers. As a result of the competition, three winners from the USA were identified who shared a joint prize of $ 100 thousand at the second stage of the competition. Next month, NASA will choose the final and only winner. The developers of SEArch + / Apis Cor preferred to settle the colonists in upright dwellings with sheltered windows that let in natural light. This will minimize the cost of lighting and save due to this energy. The design of the walls is universal, allowing constant improvement. It is planned to create houses from the Martian regolith. The Team Zopherus project focuses on local building materials, in particular Martian sand, which is the main component for special concrete. Earthlings will only have to “take” with themselves wire-frame metal structures, which, however, can also be made on site using 3D printing. Enthusiasts from Mars Incubator offer a design based on hexagonal modules open to create structures of various sizes and purposes. The main building material is also regolith.
