Question July 16, 2022 1:17 am RobVG

The surface temperature on the moon varies +- 200° F and even more depending on latitude. There’s no atmosphere on the moon so there’s no “air temperature”. As my HS physics teacher said, temperature in a vacuum is “undefined”

My question is, ignoring radiation, could someone survive on the moon sometime between sunrise and sunset with only a breathing apparatus and street clothes. Could radiant heat keep them alive? (Also ignoring that their blood would boil).

                  • That's a possibility. Fall away boosters with larger fins are commonplace. by RobVG 2022-07-24 19:49:35
