I am toying with putting a science lab on Minmus but I have never done anything like this before. I am using TAC life support mod and thought about adding these to my life support section but I noticed that when added, they don't extend the number of days your resources last (at least not in the TAC window in the VAB). I assumed that if a large water and waste containers gave you X number of days worth of water and Y number of days worth of waste storage, that adding a purifier would give you X+ days worth of water and Y+ days worth of waste storage since you would be reclaiming some of that water instead of sending it to you waste tank. So how exactly do these things work? Also, I found my first anomaly today while landing at Minmus' Slopes biom. (was so excited when I realized what it was that I nearly crashed my lander lol) I put the lander down right next to it and sent Jeb on an EVA, but neither Jeb nor any of my equipment acknowledge it's presents. Is there a way to get science from them, or are they purely decorative?
