I still stand by that the current DSS is punishing explorers for doing exploration. We should get rewarded a lot more for selling detailed information about a planet's composition and features, not less. I haven't done the real timing, but I'm sure you'd lose less revenue by simply FSS HMC's and not fly out to DSS them, because of how close we have to get inside the gravity well. I mean, we're selling data to corporations to save them time to find profitable planets to exploit.
It would be easy for the DSS to have a binocular so we could launch probes at a greater distance. I previously said up to 5 Ls away, maybe even more, to give us a chance to cover some ground on a long trip. As it is now, it's an unrewarding time sink to explore.
Another thing that could improve gathering exploration data is how the data is sold. Make different economies and states determine what the want to buy, how much and how distant. Only a huge economy ought to be interested in buying data from the other side of the galaxy. Mining economies should be more interested in buying data about mining prospects, expanding economies should be more interested in terraformable stuff and so on. Maybe for the next season, there could be more signs for alien life to sell for factions interested in that, paying depending on them having sinister or friendly intentions.
But, first, fix the tools we have now to make exploration great again. \o/
