Ah! neat!Yes there are asteroids bases (32) since version 2.2. Most of them are in nebulaes around bubble.
Each of them is dockable with refuel, repair restock service. Some have also outfitting, and some have shipyard.
The DSN Luxury Tour aims to visit most of them.
You are more than welcome. Feel free to join us anywhere.I just found out about this from the Frontier's newsletter. Unfortunately I'm working tonight, but I'll refit my Orca and join you on the first waypoint. Time to get that pesky elite on exploring!
