阿波罗15号在月球地平线上拍摄地球
This view of the crescent Earth over the Moon’s horizon was taken during the Apollo 15 lunar landing mission. Apollo 15 launched from the Kennedy Space Center on July 26, 1971 via a Saturn V launch vehicle. Aboard was a crew of three astronauts: David R. Scott, mission commander; James B. Irwin, lunar module pilot; and Alfred M. Worden, command module pilot.
Designed to explore the Moon over longer periods, greater ranges, and with more instruments for the collection of scientific data than before, Apollo 15 included the introduction of a $40 million lunar roving vehicle (LRV) that reached a top speed of 16 kph (10 mph) across the Moon’s surface.
The successful Apollo 15 lunar landing mission was the first in a series of three advanced missions planned for the Apollo program. The primary scientific objectives were to observe the lunar surface, survey and sample material and surface features in a preselected area of the Hadley-Apennine region, setup and activate surface experiments, and conduct in-flight experiments and photographic tasks from lunar orbit. Apollo 15 televised the first lunar liftoff and recorded a walk in deep space by Worden. Both the Saturn V rocket and the LRV were developed at the Marshall Space Flight Center.

这张月牙形地球在月球地平线上的照片是阿波罗15号登月任务中所拍摄。1971年7月26日,阿波罗15号通过土星5号运载火箭从肯尼迪航天中心发射升空。船上有三名宇航员:任务指挥官大卫·R·斯科特;登月舱飞行员詹姆斯·欧文;还有指挥舱飞行员阿尔弗雷德·沃登。
阿波罗15号旨在更长时间、更大范围内探索月球,并配备更多用于收集科学数据的仪器,其中包括引入了价值4,000万美元的月球漫游车(LRV),该月球车在月球表面的最高速度为16kph(10mph)。
阿波罗15号登月任务的成功是阿波罗计划一系列三个高级任务中的第一个。主要的科学目标是观察月球表面,在哈德利-亚平宁地区的一个预先选定的区域对材料和表面特征进行调查和取样,设置和启动表面实验,并在月球轨道上进行飞行实验和摄影任务。阿波罗15号在电视上播放了第一次月球发射,并记录了沃登在深空的行走。土星五号火箭和LRV都是在马歇尔太空飞行中心研发的。
