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?'

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.

The conditions on the surface of the moon are harsh. Temperatures swing between 250 and -280 degrees Fahrenheit.

It was feared the flags would be lost due to the rough lunar environment.
