Over the past month, Cassini has been dipping into the very top of the Saturn’s atmosphere on its last few passes by the planet. It has measured the particles, radiation and magnetic field there. Now, it’s diving right in and capturing data deeper in Saturn’s atmosphere than any spacecraft has ever ventured.

“We’ll be about 2000 kilometres lower than we’ve ever been, and then the atmosphere will eventually swamp us and overcome us and the spacecraft will melt,” says Julie Webster, Cassini’s manager of spacecraft operations at NASA’s Jet Propulsion Laboratory.
