I brought this issue up in a earlier post some time ago. (Thread was something like: Galciv 2 features that should die)
I suggested these alternatives:
Scout Ships when set to scout would give the option of
1) Going to random locations in unexplored space, or just random locations is space was explored.
2) Going to random locations.
Also I suggested that Survey Ships would default to these if there were no anomalies in reach rather then just sitting there.
Anyway, someone from Star Dock said that it had been addressed but they didn't give any details.
