I am on a long term exploration voyage in my fleet carrier intending to explore and mine my way to a full hold. On my latest jump I found a planet with 25 geological signals and decided to take out my rather neglected SRV and check them out. I intended to check all of them, so far I have checked 7 and though I am getting a lot of good materials all the scans of the fumaroles are exactly the same type as the first one I scanned. If all of the planetary signals are of the same type then is it worth scanning them and should I just concentrate on gathering the materials instead?.
