Many lessons learned during Cassini's mission are being applied to planning NASA's Europa Clipper
mission, planned for launch in the 2020s. Europa Clipper
will fly by the icy ocean moon dozens of times to investigate its potential habitability, using an orbital tour design derived from the way Cassini has explored Saturn. The Europa Clipper
mission will orbit the giant planet -- Jupiter in this case -- using gravitational assists from its large moons to maneuver the spacecraft into repeated close encounters with Europa. This is similar to the way Cassini's tour designers used the gravity of Saturn's moon Titan to continually shape their spacecraft's course.
