NASA's Cassini spacecraft has captured new detailed photos of Saturn's second largest moon Rhea.
The images were taken Saturday, March 10, as the craft flew by at an approximate distance of 26,000 miles.
The images revealed two large impact basins on the rocky moon's icy surface--the 300-mile-wide Mimaldi basin and the 200-mile Tirawa basin, United Press International reported.
The Cassini spacecraft was launched in October 1997 in a joint mission funded my NASA and the Europeans Space Agency, and has been gathering data on Saturn and its moons ever since.
