Aging

Over time, parts on your ship will age and become less reliable as their age increases. There are two ways for a part to accumulate age.

With time

Naturally, just by being in use a part is aging. Some parts will age continously (e.g, tanks, that are always in use when they are full), while others will only age when you are using them (e.g, engines, that age only when they are being fired).

With heat

High temperatures can ruin materials over time. This effect is simulated in the mod, too: the higher the temperature of the part, the faster it will age. The temperature will cause every part to age, even when it is not being used.
