Why not make the craft in such a way so that when it points in dish to earth, its camera can still point to pluto, heres a tip, how about install TWO cameras with 180deg fov, and then you will never miss your target.
Heres a clue, how about a motorized lens that can rotate the camera or lens or whatever.
Heres another clue, design an ultimate design thats fit for any planet/flyby, a generic all purpose best of all situations craft, with plugin addons for specific sensors.
Stop redesigning from scratch each craft for 700 million. NASA you need to learn from the PC industry, modular design. Reduce costs, send more probes, or always send up pairs, like the rovers.
Second, why are they still sending images in JPEG '94, they should use JPEG2000, to reduce the data by another 300% or send 3x more images.
JPEG'94 is junk.
