Four decades after the last astronauts landed on the moon and planted an American flag in lunar soil, scientists wondered: 'Does that star spangled banner yet wave?'
在最后一名宇航员登陆月球并在地面插上美国国旗四十年之后，科学家在想：“星条旗依然舞动着吗？”
The most recent photos of the moon taken by NASA's Lunar Reconnaissance Orbiter Camera show that the flags still exist - except the one planted by Neil Armstrong and Buzz Aldrin after they became the first humans to touch the lunar surface July 20, 1969.
美国航天局月球勘测轨道飞行器照相机最新照片显示，国旗仍然矗立着——除了尼尔·阿姆斯特朗和巴兹·奥尔德林插下的那面国旗不见了，他们于1969年7月20日成为第一个登上月球的人类。
The conditions on the surface of the moon are harsh. Temperatures swing between 250 and -280 degrees Fahrenheit.
月球表面条件恶劣。温度早晨可达到242华氏度，晚间可达零下280华氏度。
It was feared the flags would be lost due to the rough lunar environment.
有人担心恶劣的月球环境会致使国旗丢失。
