NASA’s Cassini spacecraft will whiz past Saturn’s smoggy moon Titan on April 7, sniffing the moon’s atmosphere as it makes the closest planned pass for the remainder of the mission. Cassini’s point of closest approach during the flyby, named “T-100” by mission planners, is targeted at a mere 598 miles (963 kilometers) above the moon’s haze-obscured surface.

The close flyby altitude enables Cassini’s Ion and Neutral Mass Spectrometer, or INMS, to sample the composition of Titan’s upper atmosphere as the spacecraft zooms past.
