Abstract:

The evidence for the existence of the so-called linear thermal anomaly recently reported on the western margin of Mare Humorum is examined critically and rejected. Whether the anomalous cooling of Mare Humorum considered as a whole can be caused by internal heating is also rejected on the basis of 1 the measured temperature differential compared to the environs observed during the lunar day, 2 the required temperature gradient, and 3 energy considerations compared to terrestrial heat flow. It is concluded that it is extremely doubtful that any of the observed hot spots are caused by internal heating. Author
