  Ligeia Mare, shown here in a false-color image from NASA's Cassini mission, is the second largest known body of liquid on Saturn's moon Titan. It is filled with liquid hydrocarbons, such as ethane and methane, and is one of the many seas and lakes that bejewel Titan's north polar region.

T-93: Monitoring the Lakes

At just before the closest point during this flyby, the visible and infrared mapping spectrometer (VIMS) instrument will acquire images of Ligeia Mare and Punga Mare, the second and third largest known bodies of liquid on Titan respectively. Monitoring the Titan lakes is important for looking at how they evolve over time and seasons. Are they evaporating and getting smaller, or staying the same, or getting larger?

Earlier in this flyby, observations of specular reflection will be possible if liquid bodies are present in the area near Ara Fluctus (57.3 N, 131.2 W) and (58.4 N, 151.7 W). After closest approach, ISS will acquire high-resolution images of Ontario Lacus on the terminator as the Sun sets for southern winter.
