I am very familiar with quantity measurement in shuttle RCS and OMS and it involves using the pressure and temperate of the helium.
Let's make this into an Apollo Program Q&A thread.I'd like to know how the Atmosphere in teh Command module was composed and at what pressure it was mantained. I'd also like to know if it was different then what is used on Soyuz how this was handled during ATSP
My guess would be that with such an atmosphere you need less (no?) prebreath time when doing an EVA.
How came they adopted the idea of pure O2, that also lead to the Apollo 1 disaster? From a layman point of view it is so absurd. Carrying people in an Atmosphere alike the natural one on earth seems to be the only logical way to do it, but hey must have had reasons, what were they?My guess would be that with such an atmosphere you need less (no?) prebreath time when doing an EVA.

I would like to know how the Apollo 11, 12, 14 are similar to Apollo 15, and also how they differ from Apollo 15.

CM+SM?If you're looking to find out differences down to the plumbing, wiring, and subsystem details, that would require quite a bit of research beyond anyone's quick replies here.
Just simple easy stuff.. comparing and contrasting 11, 12, 14, to 15
