If an item is not use for a period of time, it could be slowly covered by dust (or ice). The effect : power panels works bad and finally do not work at all. Beacon could work less. It means a approximate signal, difficulties to read the beacon's name. (when beacon will have names).
You just have to touch once or several times the soiled items to clean it.
More a planet is hostile, more the stuff will be dirty faslty and strongly.
It could be ice on ice planet.
I know it is just a detail, a visual aspect and not a priority but it could be a little extra for the player game'
