Flooded canyons on Titan NASA's Cassini spacecraft pinged the surface of Titan with microwaves, finding that some channels are deep, steep-sided canyons filled with liquid hydrocarbons. One such feature is Vid Flumina, the branching network of narrow lines in the upper-left quadrant of the image. The image was acquired on 26 September 2012, on Cassini's 87th close flyby of Titan.
