Sounds like a good start. Also, I appreciate that you remembered that exploration exists: I look forward to seeing more details on that later. Although I don't think it needs large adjustments, but who knows.
About the only larger change I'd suggest there would be to move more credits from the DSS mapping to first discovery scans (with the FSS) instead: players shouldn't be compelled to waste quite large amounts of time flying out to an unlandable body, just to get more credits (and a second tag), but nothing more to actually
explore.
For example, read
this account of a player new to exploration who thought that DSS-ing every planet was a must, and had gotten rapidly bored with exploration as a result.
Oh, and I'd recommend revisiting multicrew exploration, where currently crew members who help the host with exploring don't get
anything for their effort. In my opinion, those who join up as crew and scan bodies with the FSS should receive vouchers that can be turned in for credits, but not getting any tags on the bodies.
Also, on the subject of CQC and players potentially gaming the system: CQC should probably not be the highest-earning gameplay, so that folks who'll want to farm credits will flock there, but it still would be nice to earn something more than the tiny amounts we currently get. It's mostly just about the message said amounts send.
