If Galileo Galilei had sat in mission control for the Cassini spacecraft when it entered Saturn's orbit, he would have been astonished. When he discovered the planet in 1610, looking through a primitive telescope, he perceived Saturn's rings as two large moons flanking the planet. Cassini is now helping to answer fundamental questions about the rings and capturing stunning close-up imagery that Galileo could never have imagined.
