I would like to see a special ship class you select like you do tanker.
Call it 'Survey'.
It would classify a ship as a survey vessel that would then get special conditional orders to allow it to have a survey team assigned (loaded, multiple teams?) and take them around and let them team survey objects (moons, planets, and asteroids).
Maybe as a limitation is should have to be a certain tonnage (HS) like 500 - 600 tons or something.
