This study examines the impact of vacuum conditions on the angle of repose of a mare-type lunar soil simulant. Two measurement methods were used: a rotating drum for dynamic angles and a fixed funnel for static angles, both in a high-vacuum chamber. Vacuum exposure significantly altered both static and dynamic angles, with static angles decreasing likely due to moisture removal and interparticle cohesion changes. Platform geometry influenced static angles. Results highlight the need for vacuum testing in lunar simulations. cept=%2A%2F%2A https://api.elsevier.com/content/object/eid/ https://api.elsevier.com/content/object/eid/ https://api.elsevier.com/content/object/eid/ https://api.elsevier.com/content/object/eid/ https://api.elsevier.com/content/object/eid/ https://api.elsevier.com/content/object/eid/ https://api.elsevier.com/content/object/eid/ https://api.elsevier.com/content/object/eid/ https://api.elsevier.com/content/object/eid/ https://api.elsevier.com/content/object/eid/ https://api.elsevier.com/content/object/eid/ https://api.elsevier.com/content/object/eid/ https://api.elsevier.com/content/object/eid/ https://api.elsevier.com/content/object/eid/ https://api.elsevier.com/c
