   The mission of the Io Orbiter and its lander is study Jupiter's moon Io, both from orbit, and from the surface itself. To get to Io, the orbiter along with its massive booster stage needs to do a fly-by of Venus, followed by two fly-bys of Earth. Upon arriving in Io Orbit, the booster is detached, and the orbiter deploys its instruments. The Io Lander then detaches, and begins its decent onto the surface of Io. Once the lander is safely on the surface, and its instruments deployed, the spent booster stage burns the last of its fuel and crashes into the surface, yielding valuable seismic information for the lander. Following the de-orbiting of the booster stage, the Io Orbiter changes its inclination up to 95 degrees to place itself into its final science orbit.
   This mission is not for the faint-hearted, you need a a good knowledge of how to do multiple flybys, and a lot of patience.
