As NASA’s Cassini spacecraft moves toward its Grand Finale, it will conduct its final and closest flyby of Saturn’s moon Titan on April 22, 2017. This last visit is a targeted flyby, meaning Cassini will use either its rocket engine or thrusters to alter its course.
At 2:08 a.m. EDT (06:08 GMT) April 22, 2017, the probe will make its 127th flyby of the large moon. It will pass over Titan’s surface at just 608 miles (979 kilometers), where instruments will conduct closeup observations of the hydrocarbon lakes near the moon’s north pole and use radar to look through its atmospheric haze and image surface detail.
