Titan is Saturn’s biggest moon—with a radius of approximately 1,six hundred miles, it is larger than planet Mercury—and is the second-biggest withinside the sun gadget. Scientists care approximately Titan due to the fact it is the handiest moon withinside the sun gadget recognized to have clouds, floor beverages, and a mysterious, thick ecosystem
. The bloodless ecosystem is on the whole nitrogen, like Earth’s, however methane on Titan acts the manner water vapor does on Earth, forming clouds and falling as rain and carving the floor with rivers. Organic chemicals, derived from methane, are found in Titan’s ecosystem, lakes and rivers, and might provide clues approximately the origins of life.

“Titan has a lot thrilling activity—like flowing beverages and shifting sand dunes—however to apprehend those tactics it is beneficial to recognize how the terrain slopes,” says Ralph Lorenz, of the Johns Hopkins University Applied Physics Laboratory
, who led the map-layout group. “It’s particularly beneficial to the ones analyzing hydrology and modeling Titan’s weather and climate, who want to recognize whether or not there’s excessive floor or low floor riding their models.”
Titan’s thick haze scatters mild in approaches that make it very difficult for far off cameras to
“see” panorama shapes and shadows, the standard technique to measuring topography on planetary bodies. Virtually all of the statistics we’ve on Titan come from NASA’s Saturn-orbiting Cassini spacecraft, which has flown beyond the moon almost a hundred instances during the last decade. On a lot of the ones flybys, Cassini has used a radar imager, that may peer thru the haze, and the radar statistics may be used to estimate the floor height.
“With this new topographic map, one of the maximum charming and dynamic worlds in our sun gadget now pops out in 3-D,” says Steve Wall, the deputy lead of Cassini’s radar group, primarily based totally at NASA’s Jet Propulsion Laboratory in Pasadena, Calif. “On Earth, rivers, volcanoes, or even climate are carefully associated with heights of surfaces—we are now keen to look what we will research from them on Titan.”
