I have been successful in making an off-main base mining outpost. It originally consisted of one life support room with an oxygen recycler, a matter smelter (with a food replicator too), and an airlock of course. The astronauts would come into the airlock to smelt ore, and then they would go back out to mine. I built it right next to a large asteroid chunk so they could mine it faster and easier. 98.219.173.28 02:15, 29 March 2014 (UTC)
I agree with the fact this being possible since Alpha 3 with the ability to claim and unclaim rooms. So this should be added to this page. 86.5.61.244 17:59, 28 April 2014 (UTC)
