阿波罗9号机组人员回家
Fifty-five years ago today, NASA astronauts James A. McDivitt, David R. Scott, and Russell L. Schweickart splashed down 4.5 nautical miles from the USS Guadalcanal, concluding a successful 10-day Earth-orbital mission in space. In this image from March 13, 1969, a recovery helicopter hovers above the Apollo 9 spacecraft; the astronauts were still inside the command module.
Apollo 9 was the first crewed flight of the command/service module along with the lunar module. The mission’s three-person crew tested several aspects critical to landing on the Moon including the lunar module’s engines, backpack life support systems, navigation systems, and docking maneuvers.

55年前的今天，NASA的宇航员詹姆斯·麦克迪维特、大卫·R·斯科特和拉塞尔·施韦克特在距离瓜达尔卡纳尔号航母4.5海里的太空中溅落，完成了为期10天的太空地球轨道飞行任务。在1969年3月13日拍摄的这张照片中，一架回收直升机在阿波罗9号飞船上空盘旋；宇航员仍在指令舱中。
阿波罗9号是指挥/服务舱和登月舱的首次载人飞行。此次任务的三名机组人员测试了对登陆月球至关重要的几个方面，包括登月舱的发动机、背包生命支持系统、导航系统和对接操作。
