I asked this in other boards but no one could give me answers.
So, can someone tell me:
Why can New Horizons (which is older than Dawn) take photos in a way higher resolution than Dawn can (NH: 70m/pixel at an altitude of 17.000km; Dawn: 140m/pixel at an altitude of 1400km)?
Why does a probe which should observe objects optical not take the latest camera technique along?
Why isn't there a minimum standard equipment on each probe that makes results and images of missions comparable to each other?
