That's just stupid. Why send them all that way just to put them on a rock, in orbit around a planet, when you could leave them in a free solar orbit?
Not only that, but put them on opposite sides of the sun FFS, so you don't have to wait half an orbit (15 years, in Saturn's case) to get the other half of a measurement.
