Wonder if something like the OP will be in the Q4 update.
First you must synthesise memory chips from elements acquired by shooting pebbles on a planet surface. The memory chips can then be used to store a coordinate of a surface waypoint. Once recalled, the memory chip will become degraded requiring resynthesis. The longitude and latitude are uploaded into a probe that is then fired at the planet surface. If, after passing a simple RNG test, the probe survives impact on the surface, it will start to emit a signal. The signal isn't strong enough to be ready by your ship scanners, though. However, if you orbit between 2km and 15km from the surface, you can pick up varying wavelengths of sound. The wavelengths can then be translated using a simple conversion map (only available out-of-game) into a series of colours. The colours, assuming you're not colour blind, form a pattern that will direct you to the probe which hopefully hit the precise waypoint location that you wanted. When you get close to the probe location, it will stop emitting... you know... for fun. When you finally find it you'll think to yourself what an awesome experience that was. While you're down there, don't forget to collect more pebbles to replace the memory chip.
