Abstract

In-Situ Resource Utilization (ISRU) technologies pave the way for a sustainable colony on the Moon. Above all, the construction of structures using only the available resources is an important factor in reducing costs and logistical effort. The MOONRISE project aims to melt lunar regolith using lasers on mobile platforms for the additive manufacturing of structures. This process is called Mobile Selective Laser Melting (M-SLM) and has the advantage that only electrical energy and a moving system are required. For a proof-of-principle experiment of M-SLM, which aims for creating 0D, 1D and 2D fused regolith structures on the lunar surface, we designed the MOONRISE payload. The MOONRISE payload can be accommodated on a rover or a robotic arm to ensure mobility for the melting experiments. An Engineering Model (EM) of the payload including a fiber coupled diode laser was developed and environmentally tested. The dimension of the payload is 1.5 U CubeSat. It has a mass of about 2.5 kg with further reduction potential towards flight model (FM) development. Verification tests with the EM were continued by attaching it to a robotic arm to create 2D regolith structures, i.e. flat rectangular specimens. Further tests with the EM were carried out under low gravity conditions in the large-scale research device Einstein-Elevator at the Hannover Institute of Technology (HITec), which allows experiments under zero gravity conditions for about four seconds. The Einstein-Elevator also enables adjustment of the gravity level from 0 to 5 g, a feature that was used to carry out melting experiments with the EM under lunar gravity conditions.
