Cassini's 'Last Dance': A final portrait at Saturn

October 10, 2017

In the early afternoon of September 13, 2017, the venerable and much-loved Cassini probe captured this final portrait of Saturn and its main ring system, before plummeting to fiery destruction in the planet's hazy atmosphere just 48 hours later.

Using its Wide-Angle Camera (part of the Imaging Science Subsystem), Cassini snapped 75 photos: these images can be grouped into a grid of 6 by 2. Each footprint in that grid was covered with both long and short exposures via the red, green, and blue filters, plus a longer exposure shuttered through the clear filter.

The veteran spacecraft took nearly two hours to collect these data: starting at 1:09 PM and concluding at 3:17 PM (all times are UTC). Only three moons—Enceladus, Janus and Mimas—can be picked out in the uncalibrated and compressed data.

Saturn and its rings

September 10, 2017

This global view of Saturn and its complete ring system was captured by Cassini on February 20, 2007, and is composed of 15 separate frames. It was assembled from the raw JPEG images by Ian Regan. The view is from the south, so the rings are fully lit by the Sun. It contains nearly all of Saturn's moons from Mimas inward. Clockwise from bottom center: Mimas, Epimetheus (near the left ansa), Pandora, Janus (near the top), and Prometheus (near the right ansa).
