50年前，阿波罗17号宇航员拍摄到了标志性的蓝色大理石
This classic photograph of the Earth was taken on Dec. 7, 1972, by the crew of the final Apollo mission, Apollo 17, as they traveled toward the moon on their lunar landing mission. For the first time, the Apollo trajectory made it possible to photograph the south polar ice cap, shown here along with heavy cloud cover in the Southern Hemisphere.
The Apollo 17 crew consisted of astronauts Eugene A. Cernan, mission commander; Ronald E. Evans, command module pilot; and Harrison H. Schmitt, lunar module pilot. While astronauts Cernan and Schmitt descended in the lunar module to explore the moon, astronaut Evans remained with the command and service modules in lunar orbit.

这张经典的地球照片拍摄于1972年12月7日，由最后一次阿波罗任务阿波罗17号的宇航员拍摄，当时他们正在执行登月任务，前往月球。阿波罗的轨道第一次使拍摄南极冰盖成为可能，如图所示的是南半球厚厚的云层。
阿波罗17号机组成员包括宇航员尤金·A·塞尔南，任务指挥官；罗纳德·埃文斯，指挥舱飞行员；和登月舱飞行员哈里森·H·施密特。当宇航员塞尔南和施密特登上登月舱探索月球时，宇航员埃文斯留在月球轨道上的指挥舱和服务舱。
