Scientists have long suspected that some form of water ice survives inside deep craters near the lunar poles. 长期以来,科学家大都认为,月球两极附近深邃的陨石坑储存某种形式的水冰。
The images from Clementine also showed that some regions near the moon's poles appear to be in near-constant sunlight. 克莱门蒂号拍摄的影像同时显示,靠近月球两极的部份区域似乎处于永久日照的状态。
