One of the points the movie makes is how cold it was in the Lunar Module.
Both Lovell and Haise had heated spacesuits for their lunar excursion. Why didn’t they put them on to at least sleep warm?
I have worn a real spacesuit and they are hard to get on, hard to move in, as well as extremely warm. In fact, they probably would have been way too warm. I wore a spacesuit at Space Camp in Huntsville, AL when I was the satellite repair specialist during a shuttle simulation mission. I had to wear a light suit under it with many little pockets for ice packs. Despite the ice packs, I still got quite hot. The suits on real missions had an active refrigeration suit under the spacesuit. The astronauts on Apollo 13 didn’t have the power to spare to run the refrigeration from the ship and the battery packs would not have have lasted that long.
The lunar suits might have been too large to fit in the CM, perhaps even to get through the tunnel.
Perhaps IRL the cold wasn’t as severe as the movie made it out to be.
A quick Google says that the battery packs were good for about 7 hours, long enough for a nice warm nap.
If the old pressure suits were as warm as the ones you wore, couldn’t they have put them on until they got too hot and then taken them off or opened the closures?
Wasn’t the whole Apollo 13 incident faked by NASA anyway? If as many people insist that the moon landing was faked then surely all the other Apollo missions were also faked.
I really should know the answer to this off the top of my head, and I can’t find my copy of For All Mankind at the moment, so I’ll have to just stab at things. I’ve seen photos of the Apollo XIII crew looking haggard, inside the capsule, wearing spacesuit, so at least during part of the mission they wore them. It might simply have been that there wasn’t enough room in the LEM for 3 people in space suits. Remember, the LEM was designed for two people in spacesuits (neither it, nor the Apollo capsule had airlocks), so it would have been cramped with a third person in there, in or out of a spacesuit. Also, the suits tend to keep folks inside them pretty warm, so much so, that the astronauts have to wear water cooled undies. There might very well have been the danger that they’d overheat in the things without the undies, and they wouldn’t have wanted to risk draining the suit batteries (and only the two astronauts who would have been on the Moon would have had batteries for their suits, the CM pilot would have had to been hooked to an umbilical) for simple “comfort.”
Also, Lovell stated after the mission that it was his fault the LEM was so cold. He’d shut the window blinds to block out the sun to make it easier to sleep, and that’s what caused it to be so cold. He left them open the rest of the mission, but it didn’t help.
They took turns sleeping in the CM.
