Cassini: A History In Interviews

For 20 years, Cassini’s scientists have shared their discoveries with Science Friday listeners. Here are some of the most memorable moments.

This article is part of our special coverage of Cassini. Listen to one of the interviews Science Friday conducted with the Cassini team and marvel at the astounding images the orbiter took of Saturn and its moons. Plus, did you know the Cassini team has their own choir? 

Cassini’s descent into Saturn, ending its 20-year journey through our solar system, represents an uncommonly poignant moment for the scientists who have worked on the craft. And those of us who have followed Cassini’s path and marveled at the breathtaking images it sent back are affected as well.

Part of the reason that losing Cassini feels like losing an old friend is because we’ve been talking about its voyage for 20 years. Cassini helped us better understand Saturn and its moons, from the planet’s giant storms to the hidden surface of Titan. Along the way, the Cassini team appeared regularly on Science Friday, sharing with our listeners the amazing new discoveries the craft made.

So, as Cassini makes its final plunge into the depths of Saturn, we invite you to take a walk back into the SciFri archives and enjoy some of Cassini’s greatest hits.

December 2, 2016

The Cassini mission to Saturn has brought us visions of the gas giant’s icy satellites, a new understanding of where life may be possible, and gorgeous photos of Saturn’s storm systems and rings. Now, running out of fuel, the orbiter will spend its last months getting its closest-ever look at the rings, then dive between them and the planet to “taste” the atmosphere. NASA scientist James Green discusses Cassini’s final voyage.
