I definitely could get onboard with alot of these Ideas

(but please no misjumps straight into death - at the very max. an emergency stop please... but some variation due to Mass not fully accounted for is perfectly fine)
I sure wish I could purchase actual Exploration Map Data (or at least coarse Data - visited/unvisited - for entire Sectors).
When it comes to Map Data purchases inside civilization, I'm still extremely annoyed I often get lousy, incomplete Data for the Credits spent - yet all Systems are clearly 100% explored since a long time of course. I hate that.
Dirty little Secret #1:
Your data is not shared with any other player, period.
Universal Cartographics should be named Personal Cartographics to avoid confusion. Not publicised anywhere because it would make exploration feel as hollow and superficial as it really is.
Dirty little Secret #2:
The Galaxy can never be mapped.
Sag A runs prove this as anyone of the thousands of folks who make this run will still earrn millions mapping already mapped systems (see DLS #1 above); good for longevity of the game I suppose but kindof sucky in every other way.
Dirty little Secret #3:
Most Explorers jump in , disco horn while starring at a Star and jump out.
Why dont they explore? ADS takes seonds and importantly doesn't create wear on the ship; DSSs create wear and limit explorers.
ADS gives you a nametag on unexplored systems, and the majority of the earning potential of the system. DSS does nothing, I've done 5.5k DSSs in human space, netting ~17m for 4000 systems...had I just jumped randomly into the black for the same number of scans I'd have made 30-60m, just using the disco horn alone. In the same time it has taken me to do 5.5k DSSs I could have visited 12K systems with the disco horn and earned x3 the money and thus rank.
There are many more DLSs from the "Explorer" experiance, but naming any more would lead to inflammatory replies.....Exploration is totally cart before horse mechanics, and unfortunately no real change to this poor mechanic, rewarding people for starring at stars while honking their horns is planned AFAIK.
What would I suggest to fix this boring gameplay?
1: ADS and DSS are reversed in their rewardss; so ADS functionality stays the same, but if you want the lions share of a discovery then you have to travel to and surface scan a body.
2: ADS and DSS rewards are diminshing returns the further from human space you travel to. Nothing more immersion breaking than getting millions for mapping neutron stars/black holes many 1000s of lys out from human space, no-one in reality would pay you for such data, it's of no use to anyone....in the lore man has been in space for 1000 years, and in that time settled a bubble up to 300ly from Sol...so your data from a neutron star field 7000ly away should just be for the tourism, not for the millions.
