Titan Flyby - Feb. 27, 2006
Cassini’s Feb. 27 flyby of Titan is the first of four coordinated
Radio Science flybys that explore the interior of Titan. T22, T33,
and T38 are the others. This flyby occurs when Titan is near the
furthest away it gets from Saturn in its orbit, and the spacecraft
flyby is at a low inclination.
