Temperatures on the Lunar surface vary widely on location. Although beyond the first few centimeters of the regolith the temperature is a nearly constant -35 C (at a depth of 1 meter), the surface is influenced widely by the day-night cycle. The average temperature on the surface is about 40-45 C lower than it is just below the surface.
In the day, the temperature of the Moon averages 107 C, although it rises as high as 123 C. The night cools the surface to an average of -153 C, or -233 C in the permanently shaded south polar basin. A typical non-polar minimum temperature is -181 C (at the Apollo 15 site).
The Lunar temperature increases about 280 C from just before dawn to Lunar noon. Average temperature also changes about 6 C betwen aphelion and perihelion.
So objects can be extremly hot and extremly cold.
To cope with the extremes of temperature, most spacesuits are heavily insulated with layers of fabric (Neoprene, Gore-Tex, Dacron) and covered with reflective outer layers (Mylar or white fabric) to reflect sunlight. The astronaut produces heat from his/her body, especially when doing strenuous activities. If this heat is not removed, the sweat produced by the astronaut will fog up the helmet and cause the astronaut to become severely dehydrated; astronaut Eugene Cernan lost several pounds during his spacewalk on Gemini 9. To remove this excess heat, spacesuits have used either fans/heat exchangers to blow cool air, as in the Mercury and Gemini programs, or water-cooled garments, which have been used from the Apollo program to the present.
Just a copy/paste..I think they recycled the sweat to cool or blew it off.
insulation and reflectors to minimize heat gain, great. cooling fans in the suit, great. after much sweating, inside the suit would be saturated and that would subsequently not allow further sweat evaporation for cooling. hopefully the suit is sealed to vacuum (!) so no vapor could escape.
so I gather they have circulating cold water. ok, so the water warms up eventually. heat flows from hotter to colder so how do they get the exchangers/radiators hotter than the 260 degree ambient? (for heat flow to occur) water at that temp becomes steam under pressure, right?
now maybe if they compressed the vapor and directed it to a condenser/radiator?...I guess fans are zilch in a vacuum, though. without circulating air as a fluid flowing over the fins and tubes, heat transfer would be pitiful. the radiators would have to be huge, short of a large delta T. which has its own problems. what am I missing here?
as an aside, I wonder what happens when they have to take a leak or drop a deuce?
Hollywood sound stage? aw, who knows? Part of it looked like the desert maybe area 51 hah.
That film by the Colliers "Was it Only a Paper Moon?" on whether the manned lunar missions were faked is thought-provoking.
The dust rooster-tails kicked up by the lunar dune buggy are showing up on some TV commercial I have seen a couple times lately. In a vacuum the the dust would trace out a symmetric parabola but in that film it drops almost straight down. Looks like the dust is hitting air and decelerating.
