This should be pretty self explanatory and seems like a good coin/xp sink.
Atmospheric protection guild buffs with one buff machine for each type so if you wanted to protection from everything you need to run 3 buffs.
It could offer something like 1 point for the low 2 for the middle and 3 or 4 for the high protection so that even if you had full buffs you still needed some food or skills for T6+ planets.
