Lunar Infrastructure Could Be Protected By Autonomously Building A Rock Wall

Lunar exploration equipment at any future lunar base is in danger from debris blasted toward it by subsequent lunar landers. This danger isn’t just theoretical – Surveyor III was a lander during the Apollo era that was damaged by Apollo 12’s descent rocket and returned to Earth for closer examination. Plenty of ideas have been put forward to limit this risk, and we’ve reported on many of them, from constructing landing pads out of melted regolith to 3D printing a blast shield out of available materials. But a new paper from researchers in Switzerland suggests a much simpler idea – why not just build a blast wall by stacking a bunch of rocks together?

Japan has embarked on an exciting new lunar program that will test automated remote construction machinery for the Moon. In 2021, representatives from the Kajima Corporation, the National Research and Development Agency, the Japan Aerospace Exploration Agency (JAXA), and the Shibaura Institute of Technology announced they would be working with the Ministry of Land, Infrastructure, Transport, and Tourism (MLIT) to develop a next-generation construction system (A4CSEL®) that will enable the creation of lunar infrastructure.

This new collaborative venture, known as the Space Unmanned Construction Innovative Technology Development Promotion Project, will create an A4CSEL system capable of operating in the harsh lunar environment. In a recent statement, Kajima announced that it would connect the approximately 20-square kilometer (7.72 mi2) Kashima Seisho Experimental Field with JAXA’s Sagamihara Campus. Here, they are conducting experiments to validate automated remote construction machinery in a simulated lunar environment, which could lead to the creation of a lunar base!
