Space-Capable Laser for Mars/Lunar ISAM Robotic Vacuum Welding

Fibertek proposes developing a space-capable laser for Laser Beam Welding (LBW) on Mars, the Moon, and other planetary surfaces, as well as for on-orbit satellite-based NASA and commercial applications. This high-powered laser is crucial for automated robotic LBW manufacturing, which will be used to build communications towers, infrastructure, and habitats on Mars and the Moon initiatives and commercial space stations. Laser Welding might provide a significant cost saving and program accelerant for the US new Golden Dome initiative. The program aims to rapidly mature a minimal viable space welding laser product to TRL 6 by 2029-2030 for a potential space tech demo mission. The laser will be designed to meet space launch and lunar surface environmental requirements. The Phase II deliverable can be tested by NASA in a laboratory or during a parabolic aircraft flight testing program. This SBIR will initiate development towards a near-term tech demo and a roadmap for a high-reliability, 5–10-year space laser welding capability. Laser beam welding is essential for creating larger structures, repairing assets, and repurposing materials. It enables automated robotic manufacturing, which can build tall communications towers, infrastructure, and habitats. Laser welding in space reduces costs and produces stronger, more reliable joints than other methods. It also offers flexibility for real-time repairs, recycling, and re-purposing of materials.
