If you look on your right UI, and scroll through your accomplishments, at the very bottom, under exploration (I think, I am at work, so I do not have it in front of me) there is the number of systems you visited, plus Level 2 Scans and Level 3 Scans. Now I have a Advanced Discovery Scanner (finds all astronomical objects within a system) and a Detailed Surface Scanner (allows you to scan planets/stars/asteroid fields) once you get close enough. My question is: How do you do a Level 2 scan or a Level 3 scan? Am I missing something?
