"Cassini has yet to have an extremely close flyby of one of Saturn's small, irregularly shaped satellites. No such flyby is scheduled for Cassini's primary mission, so should one ever take place it would have to be during a possible extended mission. This rendering shows a fictional flyby of Calypso, one of Saturn's small satellites. In reality, Calypso's surface probably appears smoother than in this rendering. To better show instruments and individual components, the spacecraft is rendered without most of it thermal protection blanket."
