According to Wikipedia's article on JunoCam (and I have seen other corroborating sources):
JunoCam is not one of the probe's core scientific instruments; it was put on board primarily for public science and outreach, to increase public engagement, and to make all images available on NASA's website.
The article does go on to say essentially that researchers will get what science they can out of the images.
To me the images look quite good. What are some things about the camera that make it less valuable for science than earlier cameras that were among the core scientific instruments?
Possible answers might be:
- Images at fewer frequencies (Is that true? What particularly desirable frequencies are missing?)
- Less suitable lens or lenses (Again, is this true? If so, in what way?)
- Information about what you can't tell about Jupiter because of the weaknesses would be good too.
