To clarify my previous position. Though I most certainly like everything I have read about the new mechanics, I would like to again offer a few additional mechanics that I feel could make them even better.
SCIENCE MODULE: The biggest thing, for me, is to have a module that will allow players to use skill to solve various in-game mysteries without the need to leave the game, as well as allowing players to unlock certain types of salvage-like encrypted data, rebel transmissions or military plans-to either obtain valuable Intel or even unlock a mission.
In the context of exploration, however, I would allow players to feed lower order exploration data to obtain a crude form of the next level of data. For example, Emission & Gravity Well data could be fed in to get a crude version of the system map (that shows merely the number & relative size of stellar bodies.....but no details).
Another example is that if a player has gotten info on a planet using Emission/Gravity data, they could feed this info into the science module to get a crude estimate of the surface features on the planet & their locations.
In both cases, though, the data gained would be worth far less-in credits, ranking & first explored/mapped terms-than doing it via the methods described in the OP.
MANUAL PROBING: If players run out of probes-& cannot synthesise more-or just want to do the detailed scsn "by the seat of their pants", then they should be able to replicate the mechanics of probe scanning using their ship (minus the crashing part). This scanning approach should be fairly dangerous, & require skill, & wouldn't give the same amount of resolution of surface features (larger potential area that the surface features could be within) but at least provides alternatives to the probe only approach.
SURFACE FEATURE LOCATION: Even with probes, I *really* don't want the precise location of surface features to be revealed. Though eyeballing an entire planet for geysers is no tun, knowing precisely where they are & being able to fly straight to them, first time, is equally no fun. Just give us a 5km, 10km or 20km circle, for.example, within which the features are most likely to be......that way we still get the enjoyment of using our eyeballs and/or Wave Scanners to narrow down the precise location. This circle would be visible on the HUD & on the holographic pic of the planet, but would become a plottable point once fully discovered.
