It is. On the other hand, I get a perverse satisfaction from the times I forget to wear the suit and almost suffocate on an airless moon somewhere before I remember to dress properly.

It doesn’t help that the “dying from no atmosphere” warning looks exactly the same as the one you always seem to get for too hot/too old/solar radiation/noxious fumes/high pollen count.

Of course, I’ve also been known to take the suit off on airless worlds just for screenshot purposes. Not generally without activating Personal Atmosphere though :)
