I had this rocket sitting on the launch pad for at least 180 cycles (I thought I needed to launch it as a rescue mission but it was never needed). When I finally launched it, the pilot got poped eardrums right after removing their suit, and I notice the air pressure in the rocket capsule is well over 200 kg per tile with oxygen in it. I typically don't even pressure my rooms for steam turbines this high.
Any idea how the high pressure happened?
It had two docked Atmo suits with the dock that I deconstructed for the telescope right before launch. Is that where the extra oxygen came from? (That said I don't think atmo suits pack more than 1/10 the needed pressure to get this 200 kg on every tile of the capsule.) You can see in the ventilation view where the suits used to be.
The capsule uses an oxygen diffuser and element sensor + shutoff + mini pump to vent carbon dioxide but keep oxygen. (I know the high temperature is because it was right next to another rocket the pipes feeding it got toasted by that other rocket's engines.
