Abstract

The study explores the integration of high-fidelity Virtual Reality (VR) into astronaut training for lunar analog missions. A realistic VR simulation was developed to represent lunar terrain, allowing participants to perform critical tasks under simulated lunar conditions. Specifically, participants navigated from a compromised lunar habitat (ILMAH) facing a pressure breach, to a secure facility, testing their ability to respond effectively to emergency scenarios. Participants underwent three sequential trials to assess how VR and physical constraints influence gait and performance: (1) a baseline trial measuring natural gait without equipment; (2) a trial incorporating a real spacesuit and lunar gravity simulated through an offloading system; and (3) a trial combining the spacesuit, offloading system, and immersive VR. Participant feedback on realism, mobility, task efficiency, and psychological readiness was gathered via post-trial questionnaires, while gait and movement data were recorded using motion capture technology. This research addresses significant gaps in lunar analog training, evaluating the effectiveness of VR under lunar-simulated gravity in enhancing physical performance, spatial orientation, and psychological preparedness. Findings from this study aim to contribute to the development of cost-effective and high-fidelity VR training methods, supporting the advancement of future lunar exploration missions.
