Are we only interested in mapping impact craters? (ie. not interested in mapping volcanic craters.)
The relatively new impact craters are lots easier to spot. Are the scientific goals here interested more in the newer ones, or are the goals to look at the more ancient ones too?
I've noticed that it takes me quite a while longer to define the outlines of the 'flat floor' craters. Those whose rims are deteroriated or broken by another impacts may be important. Just how much time should I be taking on these elder craters?
BTW...enjoying my experiences here very much. Thanks
