Are you a tralveing explorer or a "real" explorer?
Jump, Honk, Jump = Traveler
Jump, Honk, DSS scan everything = Die Hard Explorer
Jump, Honk, Jump = Works the same way now; probably a bit more money compared to prior.
Jump, Honk, DSS scan = Can now be done without actually having to travel 500K Ls in order to scan the planet; some people have DSS-scanned systems with over 150 boddies in less than 20 minutes with this new system. DSS-scanning, in the past, meant that you had to travel close enough to each body in order to DSS-scan it. In a system with 150+ bodies, that would have taken hours and hours to do with the old system.
This is what this new system is about.
Probing is a NEW layer... yes... this means that you have to travel to the planet to probe it.
However, during the DSS-scanning (that now can be done without having to travel to the planet) it will reveal the number of Surface POIs, such as 37 Geological structures, 15 Biological structures, 5 Guardian structures, 1 Thargoid Structure.
So, you only need to travel to bodies that show something you are interested in... once there, you probe it, and it will show POIs that you can land on.
If this, still, doesn't feel like an upgrade to exploration... I'm not sure what to say to you, to be honest.
