Finally got my SSTO to Minmus, where i have a mining train to refuel. And there is one more miner at Ike, so i can fly even further. Now i am at Duna. I only have enough fuel for DeltaV 2000m/s so i am collecting fuel from scraps (my outpost crashlanding) so i can get at least back to orbit where can my miner come for me to refuel again. I could probably place a miner at Duna as well, but im not planning to go there any more once i save the Kerbals from the outpost. Thats why the miner is at Ike, im planning to get this to Laythe and back. the SSTO costs about 230k so far.
