阿波罗11号升空
55 years ago on July 16, 1969, NASA’s Apollo 11 spacecraft launched from the agency’s Kennedy Space Center in Florida, as seen in this photo. Astronauts Neil Armstrong, Michael Collins, and Buzz Aldrin were aboard.
Apollo 11’s primary mission objective was to fulfill a national goal set by President John F. Kennedy on May 25, 1961: perform a crewed lunar landing and return safely to Earth before the decade ended. Additional flight objectives included scientific exploration by the lunar module (LM) crew, deployment of a television camera to transmit signals to Earth, and deployment of a solar wind composition experiment, seismic experiment package, and a Laser Ranging Retroreflector. During the exploration, Armstrong and Aldrin were to gather samples of lunar-surface materials for return to Earth. They also were to extensively photograph the lunar terrain, the deployed scientific equipment, the LM spacecraft, and each other, both with still and motion picture cameras.

55年前的1969年7月16日，NASA的阿波罗11号宇宙飞船从佛罗里达州肯尼迪航天中心发射，如图所示。宇航员尼尔·阿姆斯特朗（Neil Armstrong）、迈克尔·柯林斯（Michael Collins）和巴兹·奥尔德林（Buzz Aldrin）登上了飞船。
阿波罗11号的主要任务目标是实现约翰·肯尼迪总统在1961年5月25日制定的国家目标：在十年内完成载人登月并安全返回地球。其他飞行目标包括登月舱（LM）机组人员进行科学探索，部署一台电视摄像机向地球传输信号，以及部署太阳风成分实验、地震实验包和激光测距逆反射器。在探索期间，阿姆斯特朗和奥尔德林将采集月球表面物质的样本返回地球。他们还将广泛拍摄月球地形，部署的科学设备，登月舱飞船，以及彼此，使用静态和动态摄像机。
