The FSS scan reveals planet details such as possible Geological and Biological locations. The Surface scan reveals the precise locations and the Composition scan reveals the contents.
However once the FSS has revealed planets with possible locations this is not recorded anywhere else so it is tricky to go back to review a previous scan. Ideally the System map information for each planet would display the number of geological and biological locations after the initial FSS scan.
Even better, the 3-D individual planet views in the System map would keep a recored of the locations and even display the Composition scan results.
