Scientists at the University of Florida are pioneering a method to bend materials using lasers, enabling astronauts to build structures on the moon with resources already present there. The research, recently published in Lasers in Manufacturing and Materials Processing, demonstrates how concentrated light can shape lunar soil glass into functional components, potentially eliminating the need to transport heavy construction materials from Earth.
A New Era of Space Manufacturing
Traditional manufacturing on Earth relies on massive machines and molds to shape materials, but these tools are impractical for off-world construction. Laser forming, the technique at the center of this research, uses focused heat to bend and mold materials without physical contact. The process can be precisely controlled by adjusting laser power, scanning speed, and total passes, allowing astronauts to shape components exactly as needed.
Victoria M. Miller, Ph.D., who leads the project, explains the broader implications: “It is also for Earth applications. We’re focused on flexible manufacturing for defense applications.” Beyond space, the technology could transform how specialized components are made on demand in remote or high-security environments.
Reducing Cargo Costs And Expanding Possibilities
Transporting construction materials and tools to space is extraordinarily costly and logistically challenging. Miller highlights the problem: “When something breaks in space, you don’t want to have to carry, you know, three spares of every part. It would be really convenient if you could just make a spare part on demand.”
Laser forming offers a lightweight, versatile alternative. Unlike heavy Earth machinery, it requires minimal volume and mass, making it ideal for space missions where every pound counts.
“So when we build things on Earth, we have machinery,” Miller said. “And just massive amounts of machinery and weight and volume are not really constraints when we’re doing conventional manufacturing on Earth.”
Adapting To Lunar Conditions
The University of Florida team tested how lasers interact with different atmospheric conditions, a crucial step for using the technique in the vacuum of space. Experiments with lunar regolith simulant revealed that the material can be transformed into glass and precisely bent using laser heat.
“One of the experiments that we did, was having a collaborator make a piece of glass out of lunar soil simulant,” Miller said. “And then we used our laser bending technology to bend the lunar glass.”
These findings, detailed in Lasers in Manufacturing and Materials Processing, suggest astronauts could construct essential structures, shelters, tools, and replacement parts, directly from the moon’s surface materials. This approach could radically reduce payload weight and mission costs.
