Abstract
NASA is soon to send astronauts to explore the Moon near the lunar South Pole, which is predominantly composed of lunar highlands regolith. Understanding the lunar ground is an essential aspect of this endeavor. This study presents the results of laboratory testing involving a 1:13 scale model of a vibrating drum roller compactor incorporating a lunar highland simulant. Surface settlements, earth pressures, and densities were measured to quantify the extent of improvement. The results demonstrate that the technique is effective in compacting the near-surface regolith simulant. Further studies are required to determine the most effective travel speed and frequency of vibration.
