Tanja discussed on NASACast Audio - International Space Station


We can launch air just like we can launch water you can lodge a tank of super pressurized air usually in a liquid form and then feet it into the atmosphere but the main way we get it is from water we use the system called the oxygen generation system that actually takes water splits the atom split the atom but uh splits at the or water molecule into oxygenhydrogen and then we could take that oxygen and pump it into the atmosphere then they are in the pure oxygen atmosphere so there's other stuff in there there's a lot nitrogen share so very sanita earth's atmosphere right yes airbase cleaning act same composition atmosphere that we have on earth and actually the same pressure to so there's there's no big difference there uh that feeds into some of the stuff that do for spacewalks but that's completely different tanja and go on it so we we we split the water molecules so then you have your oxygen which you just feed directly back into the cabin and then you have hydrogen which you can vent overboard if he just bill up a bunch of excess hydrogen or there's of process in a in a payload up there it's it's used as more of a technology demonstration so it's not really in the in the critical path so it's not a critical piece that we have to have run at all times but it's called the sobotta uses this abbadi a process where you can take that hydrogen the ad left over from your water.
