Art Center’s David Doody moonlights running mission control for NASA’S Cassini Saturn exploration

“Right across the Arroyo, we’re making plans for a real close encounter,” says Dave Doody, whose Art Center At Night seminar, “Basics of Interplanetary Flight,” is currently recruiting participants for a class that’s literally out of this world. “My team has been piloting the gangly robot Cassini in wide orbits around Saturn since 2010. But in coming years we’re going to drop in for some up-close-and-personal visits. We’ll plunge the spacecraft between the rings and the planet 22 times before letting go of the spent machine so it can burn up in the gas giant’s atmosphere like a meteor.”

This 2016-2017 segment of Cassini’s 20 year mission has been temporarily dubbed the “Proximal Orbits” by mission planners at NASA’s Jet Propulsion Laboratory, where Doody works as a senior engineer, currently leading the Saturn-bound spacecraft’s flight operations controllers. But after acknowledging that some creative person somewhere could almost certainly conjure a more mission-worthy name, NASA launched the Cassini Name Game, hoping for some better ideas.

“One thing about these orbits will be their huge roller coaster speed,” says Doody. “The camera-laden craft will reach more than 120,000 kilometers an hour as it screams past the innermost ring particles just above the hazy atmosphere. Next, it’ll slow down for three and a quarter days, coasting ‘up’ to the top of its 1.2 million kilometer-high peak, before starting to drop back in again for its next pass. Wild.”
