It could be argued that someone or something is mining the moon.
Most people can understand new white impact craters.
The crater in the right center is called Clarkson and was formed later than the original Gassendi crater. 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. Gassendi is an interesting crater but not a mining camp. Talking to yourself like this will make anybody loony.
