    “Near” the surface, it’s apparently around -21C, but its one crazy trick is surface area for heat sync. Once we start pushing heat into it, we’d have to do it in a REALLY huge surface area. Moon trenching…

      If you read the chart on that Wikipedia article carefully, the estimated temperature profile is based on data from two Apollo missions.

      All of the Apollo missions spent all of their surface time during the lunar morning, relatively early into the 14-day lunar day. They did this partially because the cooling systems couldn’t cope with the full heat of the day, and partially to ensure good backlighting during the landings.

      So there is going to be some “diurnal” surface heating and cooling that is probably modeled but not measured.
