The Gassendi View

or Why are these dudes digging up the moon?

Download gif.

It could be argued that someone or something is mining the moon. Most people can understand new white impact craters. See.... there are two of them right there in that large, old, almost submerged crater, named Gassendi. The crater in the right center is called Clarkson and was formed later than the original Gassendi crater.

Question: So what are the white angular raised objects in the center of the crater plain?

Answer: Impact shock lift, right?

Question: Then why aren't they the same shade of dark gray as the boulders on the left side of the crater?

Answer: Well, maybe there was a subsequent impact that turned them bright from ejecta.

Hum, that is possible from the closer of the two craters in the lower left quadrant.

Question: But where are the ejecta rays from those new craters?

Gassendi is an interesting crater but not a mining camp. However, I personally, would like to get some closeup shots of the complex of "pathways", assumed to be cracks in the crater floor.

Talking to yourself like this will make anybody loony.
