For the first time, scientists have mapped the whole surface of Titan, the largest moon around Saturn. The map confirms existing data showing that Titan has many Earth-like 1 that might be able to support life.
The data was collected by Cassini, a spacecraft operated by the U.S. space agency NASA.The spacecraft studied Saturn and its moons from 2004 to 2017. Astronomers used images and radar measurements from Cassini to create the 2 map of Titan.
The map shows Titan as a mixture of flat plains, hills and mountains, windblown sand areas, valleys and lakes. The mapping operation is 3 in a report published in Nature Astronomy.
Rosaly Lopes led the project. She is a planetary scientist at NASA's Jet Propulsion Laboratory in Pasadena, California. Lopes told the publication that the many similarities between Earth and Titan make the Saturn moon a great choice for 4 exploration.
“Titan has an atmosphere like Earth's. It has wind; it has rain; it has mountains,” Lopes said.
Titan is the only planet in our solar system besides Earth to have known 5 of liquid on its surface. But Titan's seas and lakes are filled with liquid methane (甲烷) rather than water.
At cold temperatures, methane goes through similar 6 as rain does on Earth. It falls to the surface across the planet to form rivers and lakes and can then evaporate (挥发) to form clouds again.
The map found that nearly two-thirds of Titan's surface is made up of flat plains, Nature reported. About 17 percent is covered in sandy hills 7 by the wind, mostly around the equator.
Unlike Earth, Titan'
