This report describes the heat flow experiments. The principal components of the
experiment were probes, each with twelve thermometers that recorded temperature variations at
the surface and in the regolith down to 2.5 m. The Apollo 15 experiment and the Apollo 17 probes
recorded lunar surface and subsurface temperatures. These data provided a history of the
interaction of solar energy with lunar surface and the effects of heat flowing from the deep
interior out through the surface of the moon. The interpretation of these data resulted in a
clearer definition of the thermal and mechanical properties of the upper two meters of lunar
regolith, direct measurements of the gradient in mean temperature due to heat flow from the
interior and a determination of the heat flow at the Apollo 15 and Apollo 17 sites. This
document is in the public domain.
