As lunar exploration and commercial activities expand, the standard end of life disposal of derelict spacecraft by impact into the surface of the Moon raises concerns about environmental consequences. Understanding these impacts is crucial for assessing risks to both scientific and commercial lunar interests. The Open University’s All-Axis Two-stage Light Gas Gun within the HyperVelocity Impact Laboratory can simulate impacts of solid and buckshot projectiles up to 6 km/s at 0-90° impact angle. This can be utilised to study spacecraft collisions with loose lunar regolith. Our research focuses on analysing surface modifications and ejecta dispersal resulting from such impacts. We aim to quantify ejecta trajectories, assess the influence of impact angles, and evaluate potential contamination of adjacent regions. This research will inform guidelines for sustainable lunar operations, ensuring the preservation of the lunar environment amid increasing human activity.
