MARS X-HOUSE is the first place winner in 100% Virtual Design within NASA’s Phase 3 3D-Printed Habitat Challenge. MARS X HOUSE employs an evidence-based design process to introduce the design and constructability of a future habitat for a crew of four to live and work on Mars for the duration of one Earth year. MARS X HOUSE is designed to exceed radiation standards in order to ensure human health, and vitally connects the crew to natural light and views of the Martian landscape.
