Lunar Moon Måne

Moon – N. Henricson

It was almost full moon (-1 day) and I was in big hurry to get a few shots of the moon surface before fog and clouds would set an end to this observing session. The results of this session were not up to my expectations but I hope for a cloudless and clear night for next time. The individual exposures were quite good considering the fog and small clouds that passed before the moon from time to time.

On the southern hemisphere of the moon you clearly see the Tycho crater named after Tycho Brahe, a Danish astronomer from the mid 15th century. It got a high albedo and the impact resulted in a crater which is quite recent in astronomical terms (108 million years ago). Samples from this crater were collected during the Apollo 17 mission which was the last manned mission to the moon.

Apollo 17 was unique in its way, partly because the first scientist (Harrison Schmitt) was onboard on a mission to land on another celestial object and also because of the lengthy moon-walks. The goal was to gather as many samples from soil and stones as possible.

One of the questions that often arise is, how is it possible that the moon is battered by so many impact craters while the earth does not reveal such landscapes? Scientists have come to the conclusion that earth does not look the same due to erosion and atmospherical and geological activities.

Today it is known that the moon had volcanic activity and also that the existence of the moon was a result of a great impact by another large celestial body that crashed into the proto-earth. This is proven by the fact that the moon and the earth share the same basic geological structure according to the samples gathered from moon’s surface during the Apollo space missions!
