That's not entirely accurate... I developed a recipe* for the purposes of using any planet lander to start a base in space above each planet without having to gather any resources on the planet other than from the lander. It is even possible to do it with the lander still in the hover at it's maximum stable height and let the lander eventually fall or despawn. You only need to have the reactor and assembler fully functional at first, then assemble the remaining parts for the medbay (which are disassembled first before abandoning the lander). Add the gas generator and survival is achieved. Only an arc furnace is initially needed, this will refine the additional metals to complete the refinery. If 'spawn with tools' is disabled you can omit one of the gas bottles and replace it with hand drill, but in that case it all becomes more risky at first Here's the recipe : * For game/server with the common 10x inventory multiplier.
