Maybe you can write Radiation and Pressure onto the background of the bars. E.g.: Where do I get Mercury? I assume to respawn instead, because higher tiers would protect me from radiation. I didn't have a chance to try it out, though, and Venus turned out to only mildly be too hot. OTOH I got a cyborg mod, and my implants are healing me, so I can't be sure. Maybe they do fill classic oxygen tanks, maybe they don't. Maybe some advanced oxygen tanks can be filled, maybe not. Maybe it's only a question of speed … I have it in the inventory while near my wireless charger. Then I searched JEI for "charger" … one charger for cyber implants, one for robots, one for generic items, one for GC vehicles, one for railcraft rails … Never having to use that, I didn't look for GC enery storage units, but now I automatically wrote "or I put it into a charging slot on my enderio capacitor which does not accept them". That might have been the clue, but with durability == 0 being my main concern, I tried that first. Then I disabled pressure damage and was protected by my regular armor. Before going to Venus, I selected peaceful. … to conquer the moon dungeon to get the plans to build the rocket to go to Venus. But once you got the shield, you're good and I now have full durability, and it's easier if that bug on Venus gives infinite durability and energy to the space suit. PS, the "h" key to add/remove modules from the space suit works while typing in JEI / the enderio inventory panel.
