    SUMMARY: NASA's Cassini spacecraft took this image of Rhea, Saturn's second largest moon on June 2, 2004, when it was 990,000 km (615,000 miles) away. Rhea is 1528 km (950 miles) across, ancient, and cratered. More than 20 years ago, Voyager discovered that one of its hemispheres has bright, wispy streaks that might be deposits of water ice. Cassini is expected to fly only 500 km (311 miles) away from Rhea on November 26, 2005, so we've got a bit of a wait before getting the extreme close-up view.

    Hi,
    It's been such a long time since voyager 1 and 2 sent back pictures of these remote and beautiful satellites, but the results from cassini have been well worth the wait.
    This picture of Rhea, along with the pictures of Iapetus and the rest of the Moons during the spacecrafts visit, are going to teach us so much more about composition and origins than we have learnt in the 20 years since Voyager. As a student I, for one, am looking forward to the rest of this mission with great anticipation.
