As there is no way to get Promethium without space yet (requested here https://mods.factorio.com/mod/EverythingOnNauvis/discussion/67dc97eabfea2eb6c9efe6a8) , I copied my Space Age Promethium Hauler, but that requires a hell lot of time to startup when not moving to get more asteroids.
In Space Age it was easily possible to do a trip to one of the first three planets to increase amount of incoming asteroids, but with this mods I just lost my ship (was able to recover it thanks to auto save :D) as like 2 or 3 minutes after starting it got destroyed by a huge asteroid while my railgun was not yet ready (not enough asteroids to get ammo).
