Episode 18: Cassini Countdown

When the Cassini spacecraft blasted into space on October 15, 1997, even the most optimistic scientists would have had a hard time predicting the mission’s success. One of Cassini’s biggest legacies will be how she gave us a clearer picture of Saturn’s 62 moons, including two worlds that scientists now think could potentially host life.

Dr. Michelle Thaller speaks with the Cassini mission’s Project Scientist Linda Spilker and with Julie Webster, a longtime Cassini engineer. Cassini will crash-land into Saturn’s atmosphere this September, ending nearly 20 years of exploration of our own solar system.

Orbital Path is produced by Justin O’Neill and editor Andrea Mustain. Production oversight by John Barth and Genevieve Sponsler. Hosted by Michelle Thaller.
