An interesting simulation to have an orbiter and lander work to arrive at a comet nucleus and drop a lander in a scientifically interesting area, observe scientifically interesting things from the lander and the spacecraft, receive data from the lander, transmit orbiter and lander data to Earth, and keep Rosetta from crashing into large chunks of comet material that spew from the surface.
