The only difference between RCS thrusters and ordinary thrusters is the control scheme, the forces they apply work the same way:ДЄny time a thruster is fired, it applies linear momentum to the ship (which is the same as translation or changing the ship speed). If you're playing on the 'survival' or higher difficulties, the functionality is the same as described earlier. This means even on Outpost, where on older versions you were obligated to use the teleporters to get back to your ship. If you are playing on the 'casual' difficulty, you can use the button to beam up to your ship anytime, except when you are in dungeons. Lastly, while you are onboard your ship, the same button will change to allow you to teleport back down to the surface at any time, without having to actually walk over to the teleporter. This means that, for example, in the following image, I am able to teleport:Д®ven though I'm underground, with ceilings and background everywhere, because I'm not too far down, and because I've punched out the one square of background where my head is, teleporting is possible. There is no background wall on the square your head is occupying.All you need to have teleporting available is that: Note that the definition of 'underground' is a bit crude.

Going underground will make it vanish, like this: Note that it will only be available while on the surface of the planet, outdoors. In the top-right of your screen, there is a button to teleport back to the ship.
