The Sea Of Tranquility takes centre stage in this image. A small area in the lower portion of the sea was made famous by the Apollo 11 mission. It is here where the lunar module 'Eagle' landed and the immortal words were spoken by Neil Armstrong 'That's one small step for man, one giant leap for mankind'. There is debate about whether Armstrong said 'a man' or missed out the 'a' - does it really matter? It is a classic line whatever!
