NASA's Cassini probe has begun reshaping its orbit around Saturn in preparation for the spacecraft's "grand finale" at the ringed planet next year.

Cassini performed a 35-second engine burn on Saturday (Jan. 23) to set up an orbit-changing Feb. 1 flyby of Saturn's huge moon Titan. It was the second of five such burns Cassini will conduct, all of which will be followed by a close encounter with Titan.

"Titan does all the heavy lifting," Cassini project manager Earl Maize, of NASA's Jet Propulsion Laboratory (JPL) in Pasadena, California, said in a statement. "Our job is to get the spacecraft to a precise altitude and latitude above Titan, at a particular time, and these large propulsive maneuvers are what keep us on target to do that."
