NASA has selected the five winning designs in the latest stage of its 3D-printed habitat competition, including a pod inspired by the anatomy of a spider and vertical egg-like container. teams were challenged to come up with a solution that tackled the issues of transporting materials to mars, considering differences in atmosphere and landscape on the red planet. nasa-mars-3d-habitat-competition-winners-centennial-challenge-07-30-2018
The multi-phase competition challenged designers and engineers to use construction techniques enabled by 3D printing technology. the shelter had to include a thousand square feet of space, enough to accommodate four astronauts on a mission to mars as well as a room to store the necessary machinery. each team was required to create digital representations of the physical and functional characteristics of a house on mars using specialised software tools.
AI spacefactory came in second place, presenting an egg-shaped structure, designed with a double shell to combat the aggressive thermal effects of mars. like the zopherus habitat, the team envisions the marsha design to use materials sourced from mars including basalt fibre, extracted from martian rock, and renewable bioplastic (polylactic acid) derived from plants that could be grown on the planet. to read more see here.
