Airless Enviroments without pressure aka space[]
To survive space you need to get a medical mask or a Gas mask and most importantly get a space suit to protect you from the low pressure and the cold and a jetpack which works just like a oxygen bottle exept you can move around in space with it if you right click on it and click "toggle".
