Titan's river maps may advise Dragonfly's sedimental journey

With future space exploration in mind, a Cornell-led team of astronomers has published the final maps of Titan's liquid methane rivers and tributaries—as seen by NASA's late Cassini mission—so that may help provide context for Dragonfly's upcoming 2030s expedition.
The fluvial maps and details of their accuracy were published in the Planetary Science Journal. In addition to the maps, the work examined what could be learned by analyzing Earth's rivers by using degraded radar data—similar to what Cassini saw.
Like water on Earth, liquid methane and ethane fill Titan's lakes, rivers and streams. But understanding those channels—including their twists and branch-like turns—is key to knowing how that moon's sediment transport system works and the underlying geology.
"The channel systems are the heart of Titan's sediment transport pathways," said Alex Hayes, associate professor of astronomy in the College of Arts and Sciences.
