NASA’s Cassini spacecraft, with an Iowa-made instrument aboard, is near the end of its 20 year voyage.
On this edition of River to River, Ben Kieffer talks with Bill Kurth, research scientist in the department of physics and astronomy at the University of Iowa, about the significance of the Cassini mission and spacecraft, currently in orbit around Saturn.
"Cassini is kind of a veteran. It arrived in orbit at Saturn in 2004, in the summer. That was about a seven year journey from the Earth," he says. "So we've been in orbit for almost 13 years."
