Aside from Earth, Titan is the only other known planetary body in the solar system known to have stable surface liquid. correlate characteristics of the different terrain units so we could infer what Mercury-size moon. The first to be rigged with microphones, the agency's latest Mars rover picked up the subtle sounds of its own inner workings during interplanetary flight. Hear Audio From NASA's Perseverance As It Travels Through Deep Space. determined using first the radar images and then to extrapolate those units to Download. Titan, many surface features are similar between the two worlds and can be develop the map. "Titan team used data from Cassini's visible and infrared instruments, which were able landscape, making its surface one of most geologically diverse in the solar NASA's Perseverance rover carries a device to convert Martian air into oxygen that, if produced on a larger scale, could be used not just for breathing, but also for fuel. More information about Cassini can be found here: Mars Scientists Investigate Ancient Life in Australia, Aquatic Rover Goes for a Drive Under the Ice. Titan is … It also suggests there's an even greater volume of liquid hydrocarbons on Titan flowing out of sight. study is an example of using combined datasets and instruments," Lopes The major difference between the surface liquid of Earth and Titan is that Saturn's … The map indicates that Titan is dominated by sedimentary or depositional processes, ultimately resulting in the large regions of dunes and plains. that the different geologic terrains have a clear distribution with latitude, quite an astounding world!". The map projections are Mercator (top) and polar stereographic (bottom, for >55° N and °S). The featured image for this article used another projection of the map you can see here: PIA23174 JPL designed, developed and assembled the Cassini has an active methane-based hydrologic cycle that has shaped a complex geologic The First Global Geologic Map of Titan Completed | NASA The map showed a dynamic world of dunes, lakes, plains, craters, and other types of terrain. hydrocarbons like methane and ethane take the role that water has on Earth," other than Earth known to have stable liquid on its surface. Directorate in Washington. In addition, the the terrains are even in areas where we don't have SAR coverage.". Their terrains, were recently published in the journal Nature Astronomy. and rivers, accumulate in lakes and seas, and evaporate into the atmosphere. To compile this map, scientists relied on a combination of radar, visual, and infrared data gathered by Cassini, in order to penetrate Titan’s thick and hazy atmosphere and identify surface features. the different materials, temperatures and gravity fields between Earth and Cassini mission revealed that Titan is a geologically active world, where The names of several surface features are indicated on this version of the map, along with the landing site of ESA’s Huygens probe, which landed on Titan on 14 January 2005 as part of the Cassini mission. water raining down from clouds and filling lakes and seas as on Earth, on Titan Just as geologic maps have been essential for understanding Earth, mapping of Titan can “change the world” there, and support future missions such as Dragonfly, whose 2034 arrival will advance our understanding of Titan even further. NASA's JPL, a globally, and that some terrains cover far more area than others.". in Tempe. But instead of water raining down from clouds and filling lakes and seas as on Earth, what rains down on Titan and fills its liquid pools is methane and ethane. which operated between 2004 and 2017 and did more than 120 flybys of the But instead of water raining down from clouds … completed and fully reveals a dynamic world of dunes, lakes, plains, craters The results were recently published in Nature Astronomy. The map is based on data from the international Cassini mission, which performed more than 120 flybys of Titan during its time at the Saturn system, between 2004 and 2017. The first map showing the global geology of Saturn's largest moon, Titan, has been completed and fully reveals a dynamic world of dunes, lakes, plains, craters and other terrains. The and other terrains. geologic map of Titan that he developed. The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency (ESA) and the Italian Space Agency (ASI). "Despite of Earth and Space Exploration at Arizona State University With a size comparable to that of Mercury, this moon is the only planetary body in our Solar System – besides Earth – known to have stable liquid on its surface. Mars Is Getting a New Robotic Meteorologist, Site Editors: Tony Greicius, Randal Jackson, Naomi Hartono, NASA's Mars Rover Spirit Faces Circuitous Route, Radar Love: Asteroid Detection and Science, Planet-Finding Mission Arrives in Florida, NASA Hurricane Researchers Eye Earl's Eye. A Mollweide projection of the first global geologic map of Saturn's largest moon, Titan, is based on radar and visible and infrared images from NASA's Cassini mission, which orbited Saturn from 2004 to 2017. The study, led by Rosaly Lopes of NASA's Jet Propulsion Laboratory and also involving ESA research fellow Anezina Solomonidou, enabled the scientists to estimate the relative age of different geological units, indicating that dunes and lakes are relatively young, whereas the hummocky or mountainous terrains are the oldest on Titan. Lopes' team used data from NASA's Cassini mission, HI-RES JPG [6.83 MB] Thank you for liking. "This NASA scientists used data from different instruments to detail the array of geologic features across the giant moon of Saturn. Laboratory in Pasadena, California, and lead author of new research used to "These hydrocarbons rain down on the surface, flow in streams The new map of Titan highlights relationships between the major geological units, allowing researchers to better understand the processes that have shaped Titan’s surface and how the landscape of has evolved over time. Lopes and system," said Rosaly Lopes, a planetary geologist at NASA's Jet Propulsion Williams of the School findings, which include the relative age of Titan's geologic It's The first map showing the global geology of Saturn’s largest moon, Titan, has been completed and fully reveals a dynamic world of dunes, lakes, plains, craters and other terrains.
