As a game mechanism, the DSS is almost pointless. Other than revealing the locations of Surface Features and HotSpots in Rings, using the DSS provides no additional details about a planet. Everything there is to know comes from the FSS so, other than additional Credits, what is the point of spending the time flying from planet to planet and firing probes at them?
I know this suggestion will not be popular but I think it would make a lot more sense if the FSS provided the basic information about a planet such as its location and type - Gas Giant, Icy, High Metal Content etc. The actual details, whether you can Land, whether it is suitable for Terraforming or is an Earth-like planet, etc should only be revealed by a Detailed Surface Scan. That would make Exploration a far more interesting exercise than just another Credit Grind.
