WAUKESHA, Wis. — NASA’s Cassini spacecraft has spent the past 4 years at Saturn. In its short lifetime, the spacecraft has discovered methane on Titan, icy plumes on Enceladus, and a vast amount of details in the planet’s rings and atmospheres.
In “Saturn revolution,” Linda Spilker, deputy project scientist for the Cassini mission, explains what Cassini teaches us about our solar system’s ringed planet and what astronomers will discover from all the new images and data.
“If Cassini’s first 4 years are any guide,” writes Spilker, “planetary scientists should expect the unexpected.”
Pick up the October issue of Astronomy to read all about Cassini and to see the stunning images the spacecraft has returned.
