My point is that you can't just conclude a prior that the capabilities could be matched by an orbiter. You need bigger and thus heavier optics to match the perf

My point is that you can't just conclude a prior that the capabilities could be matched by an orbiter. You need bigger and thus heavier optics to match the performance of a camera on the ground from orbit. The extra mass for the drone might be less than that needed for the larger optics.
