Cassini’s Final Breathtaking Close Views of Dione
A pockmarked, icy landscape looms beneath NASA’s Cassini spacecraft in new images of Saturn’s moon Dione taken during the mission’s last close approach to the small, icy world. Two of the new images show the surface of Dione at the best resolution ever.
Cassini passed 295 miles (474 kilometers) above Dione’s surface at 11:33 a.m. PDT (2:33 p.m. EDT) on Aug. 17. This was the fifth close encounter with Dione during Cassini’s long tour at Saturn. The mission’s closest-ever flyby of Dione was in Dec. 2011, at a distance of 60 miles (100 kilometers).

“I am moved, as I know everyone else is, looking at these exquisite images of Dione’s surface and crescent, and knowing that they are the last we will see of this far-off world for a very long time to come,” said Carolyn Porco, Cassini imaging team lead at the Space Science Institute, Boulder, Colorado. “Right down to the last, Cassini has faithfully delivered another extraordinary set of riches. How lucky we have been.”

This view shows the region as a contrast-enhanced image in which features in shadow are illuminated by reflected light from Saturn.

Editor’s note: Carolyn Porco and the rest of us are moved by these final Cassini images of Dione and beyond that, it is sad knowing the end is in sight of a journey that has repeatedly amazed us all with discoveries and incredibly awesome views for over a decade. ~ JN Ph7.5
