Technical Abstract (Limit 2000 characters, approximately 200 words)

In-space welding is a valuable manufacturing technology for long duration, long endurance space missions. The Mobile End-effector Laser Device (MELD) is a groundbreaking laser welding system from Made In Space, Inc. (MIS). MELD autonomously welds aerospace-grade metals to assemble large, stable structures on-orbit or on the lunar or Martian surface. These include trusses, arrays, habitats, and pressure vessels. Almost as important, MELD repairs existing structures damaged by micrometeorites or orbital debris without human intervention. MELD offers the only welding and repair system capable of functioning in conditions such as reduced pressure, microgravity, and intense radiation.

MELD is a fully functional system containing a laser welding end effector and subsystems including power, cooling, communications, verification and validation, and a foreign object debris collection mechanism. In Phase I, the MELD end effector successfully welded aluminum, stainless steel, titanium, and Inconel alloys. In Phase II, MIS proposes to build a vacuum rated end effector, refine and build optimized subsystems for the relevant testing environment, and continue testing welding both at ambient and in vacuum. Success criteria is the fabrication of welds of correct geometry without cracking or voids. Ground testing includes tensile, hardness, and helium leak testing according to ASTM standards.

MIS has extensive experience in developing in-space manufacturing capabilities. MIS has operated multiple payloads on the International Space Station and is currently working on Archinaut, a NASA Tipping Point project, developing a satellite for autonomous in-space manufacturing and assembly. MELD with its welding ability fits well into Archinaut and other MIS efforts to revolutionize living and working in space.

Potential NASA Applications (Limit 1500 characters, approximately 150 words)

MELD is platform agnostic and benefits several NASA missions. Artemis is one direct mission set that MELD can be utilized upon. When developing the lunar gateway, future habitats on the surface, or exploration vehicles, MELD provides a means for manufacturing and assembling structural segments of each of these. MELD could also be used after the system has been completed to repair or augment the systems with additional supports, patching micrometeroid damage, or adding of functional structures such as antennas or solar array segments.

Potential Non-NASA Applications (Limit 1500 characters, approximately 150 words)

The welding ability of MELD is a valuable addition to the multitude of ongoing or upcoming satellite servicing and repair missions including the DARPA Robotic Servicing of Geosynchronous Satellites (RSGS) mission, and the Northrop Grumman Mission Robotic Vehicle (MRV). As part of these missions, MELD repairs structural damage or welds propulsion or power structures to a damaged vehicle.
