We need to design a score or so or these to explore the Kuiper Belt. With base-line interferometry and phased array radar feeding into a shared system of computer memory, they could do a survey of that vast area as autonomous robots.
Multi-spectral photography for large interesting bodies would build a database of places we could explore or exploit later on.
I would sign off on that plan immediately. These little, inexpensive scientific spacecraft should have been flying everywhere in the solar system years ago.
