Other factors

-- The high altitude shots seem obscured by haze. It seems like until it got down to a certain altitude, all was haze, whereas I think the hope was there would be some clear layers, or in fact the first photos should have been high enough to be above much of the haze. Maybe it was hazier than expected most of the day way.

-- Many of the pics are duplicate surface images. I imagine on the surface they told it to take a picture every X seconds, but instead of that producing 5 or 10 images, it produced many dozens, since the probe lasted so long

-- I wonder if it wasn't spinning as much as expected. It seems like an awful lot of the pics are looking in one direction, or that the view direction changes very little from frame to frame. The ASU website did contain a note saying the "spin looked kind of erratic" but that they'd be working on putting together panoramas.
