qqp question1: "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?" question2: How would have abort mode worked on the Apollo LM spacecraft? Would it have still used the descent engine?
