Another anomaly, how did the astronauts keep cool on the Moon?
They had backpacks which dissipated heat via the sublimation of
ice from a porous plate located inside their backpack which,

You got it right, first time. It has nothing to do with evaporation, and
everything to do with radiant heat transfer.
