Mining in pre-Prospected (Mapped) Rings... How to find Hotspots again ?

[Deleted member 38366]

Took the time to check a few Metallic Rings around Gas Giants and found me some nice hotspots.

Now, having sold all Data and returning in a Mining Ship : all the Data is gone, the Hotspots don't show anymore (?)

- Analysis Mode set : nothing
- Honked Discovery Scanner : nothing (as expected)

So how does one make previously Mapped Data (Hotspots, presumably also Geological Sites etc.) visible again without carrying a Detailed Surface Scanner and Re-Mapping it all over?

Found the problem :

Without a DSS fitted, Hotspots (or presumably anything else Mapping related) apparently don't show up.

Only with DSS onboard, Mining Ships can return to places that were previously Mapped (Mining Hotspots). So that's 1 Internal less for Miners it seems.
(at least it doesn't need to be assigned to a Fire Group, presence of the DSS onboard is sufficient to make everything previously mapped visible again)
