美国航天局有一位专家叫亚当·沃兰德,他在参加一次航空项目时,偶然看到俄罗斯勘察加半岛附近有一座活火山,火山表面覆盖着积雪,卫星影像酷似字母“V”。于是,他就想搜集到更多的“字母”。经过两年的努力,亚当在朋友的帮助下,集齐了26个字母。这些字母来自于自然水系、浮游植物繁殖群、海洋珊瑚礁以及其他各种自然现象的卫星影像。有人说,这可真无聊。其实,这也是一个发现地球、了解自然的有趣过程,不是吗?你认出这些字母了吗? NASA has an expert called Adam Worland, who participated in an aviation project when he accidentally saw an active volcano near the Russian Peninsula Kamchatka volcano covered with snow, the satellite image resembles the letter “V” .
