NASA资助的科学家利用NASA月球勘测轨道飞行器（LRO）航天器的数据和计算机建模，发现了月球坑内阴暗的地方，这些位置始终徘徊在舒适的63℉（约17℃）左右。 与月球表面白天加热到260℉（约127℃），晚上冷却到零下280℉（约173℃）的区域相比，这些坑洞和洞穴可能会成为月球探测的热稳定场所。月球探索是NASA探索和了解太空中未知事物的目标的一部分，以启发和造福人类。 NASA的月球勘测轨道飞行器相机已经三次拍摄了马里乌斯山深坑的图像，每一次的光线都非常不同。中间的图像里，太阳高悬，科学家们可以看到马里乌斯山深坑底部的美景。马里乌斯山深坑深约34米（约111英尺），宽约65×90米（约2
