The doodle shows Cassini, camera in hand, shooting away as it passes by the planet. And then-- because who could resist-- taking a quick selfie.
Cassini has been collecting data on Saturn and its moons for 13 years. Now it's starting its Grand Finale, which involves making those dives between the planet and its rings before taking a plunge on September 15, 2017. That's the closest to Saturn a spacecraft's ever gotten.
Cassini was first launched in 1997.
