"Was the ""Apollo Lunar Module"" pressurized during the 6 moon landings between 1969 and 1972? If yes, then how did they open and then close the latch to get in and out of the LM while maintaining pressure? If no, then how did the astronauts survive inside the LM?"
What were the technology and the energy source used to cool the astronauts inside their suits and inside the lunar landing vehicle once Apollo 11 mission landed on the moon surface back in 1969?
