The concept of expansive human colonies on celestial bodies such as the Moon and Mars has long been confined to the realm of science fiction. However, the advancement of space exploration technologies has transformed these fantastical ideas into viable plans. As a part of this seismic shift, the Artemis program, backed by NASA and international partners, aims to land humans on the lunar surface once again within the decade.
Moon or Mars: Pioneering a Path in Space
The recently held Humans to Mars Summit (H2M) 2023 in Washington DC gathered experts from multiple space-related fields. While primarily focused on Martian exploration, discussions regarding future human settlements on the Moon were also in full swing. This is primarily due to the consensus that the Moon could potentially act as a stepping stone towards more distant destinations in space.
While government-led initiatives continue to be at the forefront of lunar exploration, private space companies are becoming increasingly proactive. A key highlight of the H2M conference was the panel discussion on “Civil Engineering and Construction on the Moon and Mars,” which unveiled ambitious plans from companies such as ICON and Astroport.
Bringing 3D Printing to Lunar Infrastructure
Melodie Yasher, the vice president of building design and performance at ICON, unveiled a vision for lunar construction rooted in 3D-printing and additive manufacturing. ICON has been successful in creating various structures on Earth using these technologies and now aspires to do the same on the Moon, backed by NASA’s support.
Shiftdelete.netAccording to Yasher, the initial focus would be on horizontal construction elements like landing pads and roadways, gradually moving towards vertical construction elements such as unpressurized structures and eventually human habitable structures. ICON plans to utilize lunar regolith (lunar soil) as a construction material, using robotic 3D-printing technology to create infrastructure on the lunar surface.
Astroport: Turning Lunar Soil into Building Blocks
Astroport, a subsidiary of XArc Exploration Architecture Corporation, is developing a unique approach to lunar construction. Sam Ximenes, founder and CEO of XArc, provided a sneak peek of their plan to convert lunar regolith into bricks suitable for constructing landing pads as part of their “Lunatron” project.
Astroport, in collaboration with the University of Texas, is developing an induction furnace nozzle capable of heating lunar regolith to create bricks. This material would then be used to construct landing pads for both robotic and crewed lunar missions.

The companies’ concepts for extraterrestrial infrastructure have been elegantly visualized in artwork and videos. However, the reality of these ambitious projects is still some way off, possibly taking decades to materialize, if they ever do. Nevertheless, the innovative solutions presented at the H2M conference offer an exciting peek into a potential future where humans make their home on the Moon and, eventually, Mars.
