Cassini Completes Tethys and Titan Flybys
This week, Cassini successfully completed flybys of Saturn's moons Tethys (June 27) and Titan (June 29).
On June 27, Cassini got a close-up look at Tethys' Ithaca Chasma, a canyon that is four times as long as Earth's Grand Canyon. Scientists are studying how this canyon formed and whether Tethys was active in the past. Two days later, on June 29, Cassini flew by Titan. The goal was to map Titan's shape in order to seek clues for the presence of a subsurface ocean, and to probe the atmosphere.
