New Iapetus Image: Details in the Dark

CICLOPS has released this new, low-resolution view of Saturn's outer moon Iapetus. This view of Iapetus was taken on March 19, one Iapetus-day after the first, relatively decent encounter with this satellite. Compare this view with one taken during that encounter. This image shows the prominent equatorial ridge, which rises to a height of 20 km in some places. Elsewhere on the satellite, two large impact basins can be seen, one along the day-night terminator at the 3 o'clock position and another near the transition between dark Cassini Region and bright Roncevaux Terra at the 10 o'clock position.

This image has a resolution of 8 km/pixel and was taken from a distance of 1.4 million kilometers.
