Whats the different between a argeted flyby and a on-targeted flyby?
A “targeted flyby” (as opposed to “non-targeted flyby”) refers to the times when the navigation team is anchoring its trajectory design to the flyby — tweaking the spacecraft’s path to take full advantage of the opportunity. Usually targeted flybys are closer, and are therefore of more scientific interest (and have more scientific opportunity) than non-targeted flybys. Targeted flybys include maneuvers to achieve a specific altitude that will allow scientists to gather as much science as possible. Typically, these flybys are within 3,000 kilometers (1,864 miles) from a moon’s surface. A non-targeted flyby is one that occurs without any maneuvers. Whenever a moon happens to be relatively close to the spacecraft’s path, Cassini simply points the instruments most likely to gather scientifically valid results and keeps going to its next destination. The distance between Cassini and a given moon in non-targeted flybys is usually more than 3,000 kilometers (1,864 miles).
