Note: This question refers to content found only in Starbound beta. As of the 1.0 stable version of the game, there is no radioactive ore in the game anymore. Ships are now fueled with liquid or crystaline Echirus fuel which is found on moons.
I am at the beginning of the game quest. I finished the No Place Like Home quest by finally getting Core Fragment ores to repair my thrusters. Now my thrusters are repaired and S.A.I.L suggests that I check out a "strange gate". I'm trying to get off my first planet to get to the gate but I don't know how to simply put fuel in my ship.
I know what to get but not what buttons to press. Also I don't know how to get radioactive ore. (Suggested on wiki) Where can I find radioactive ore? How?
