SpaceX Starship at NASA Artemis Base Camp by ICON

NASA has announced it is working with Texas-based 3D printed construction startup ICON "on early research and development of a space-based construction system that could support future exploration of the Moon and Mars. The company has 3D printed communities of homes and structures on Earth and participated in NASA’s 3D-Printed Habitat Challenge, demonstrating a construction method and technologies that may be adaptable for applications beyond our home planet." Both NASA and US Air Force have invested in company's technologies via Small Business Innovation Research (SBIR) contract.

NASA is working, via its Artemis program, to establish a long-term human presence on and around the Moon by the end of the 2020s. Construction and expansion of Artemis Base Camp will require extensive use of lunar resources, including water ice (for life support and rocket fuel) and moon dirt (for building materials).

To accomplish goals of the SBIR contract ICON has teamed up with space design studio SEArch+ and Danish architecture firm BIG in Project Olympus to develop robotic construction concept for NASA's Artemis Base Camp. Here are several conceptual illustrations from the project.

Mars Ice Home concept by NASA, SEArch+ & Clouds AO

Mars Ice Home is a feasibility study conducted at NASA Langley Research Center in 2016 in collaboration with human-centered space design studio SEArch+ and architects from CloudsAO. Responding to the problem of galactic cosmic radiation being the most significant issue for human health on long duration Mars surface missions, the concept incorporates in situ resource utilization derived water-ice for radiation shielding and as a structural component.

Water, a hydrogen-rich material, is an excellent shielding material for galactic cosmic rays – and many areas of Mars have abundant water ice just below the surface. The Ice Home concept balances the need to provide protection from radiation, without the drawbacks of an underground habitat. The design maximizes the thickness of ice above the crew quarters to reduce radiation exposure while also still allowing light to pass through ice and surrounding materials. The water-ice fills and freezes within cellular pockets of the precision-manufactured inflatable membrane. The interior of the habitat would be insulated from the ice with a cellular layer of carbon dioxide, which can easily be extracted from the Martian atmosphere.
