- Titan’s origins are more like Mars than Earth, show river maps of the three planetary bodies
New York: The origins of surface topography or elevations on Saturn’s largest moon, Titan, may have more in common with the history of the war landscape than Earth, show an analysis of the river maps of the three bodies Planetary
The environment on Titan may seem surprisingly familiar. Clouds condense and rain on the surface, feeding rivers that flow into the oceans and lakes.
Off the ground, Titan is the only other planetary body in the solar system with active rivers, even though they are powered by liquid methane instead of water.
Long ago, Mars has also been home to rivers that traversed the valleys on its now barren surface.
In an article published in the journal Science, researchers reported that Titan, like Mars, but unlike Earth, has not undergone any active tectonic plates in its recent past.
The agitation of the mountain by plate tectonics diverts the paths that borrow rivers. The team found that this revealing firm lacks river networks on Mars and Titan.
“While the process that created the topography of Titan is still enigmatic, this excludes some of the mechanisms we are most familiar with on Earth,” said author Benjamin Black, an assistant professor at the University of New York City.
Instead, Titan topography can grow through processes such as changes in the thickness of the moon’s ice crust, because of Saturn’s tides, researchers say.
For the study, the team compiled for the first time a map of the river systems of Earth, Mars and Titan.
These cards have already been made by others to Earth and Mars. The researchers generated a map of the river to Titan using images taken by NASA’s Cassini spacecraft that has circled Saturn and sent Earth images of the planet’s rings and moons since 2004.
For all three letters, the researchers marked the direction each river seems to flow.
Then they compared the topographic maps of the three planetary bodies, with different degrees of resolution.
The study also highlights the evolution of the panorama on Mars, which was once a vast ocean of water and rivers.
The main features of Mars’ topography have formed very early in the planet’s history, influencing the trajectories of younger river systems, although volcanic eruptions and asteroid impacts have marked the surface of the planet, seekers said.
“It’s remarkable that there are three worlds in the solar system where streams flow into the landscape, either now or in the past,” said Taylor Perron, professor of geology at the Massachusetts Institute of Technology (MIT).
“There is an incredible opportunity to use the land forms rivers have created to learn the stories of these worlds are different,” Perron said.
