Saturn’s moon Titan is one of the stops with the highest life expectancy in our solar system. To explore this possibility, NASA is running a project called Dragonfly to visit in 2027. Titan is quite remarkable with its thick atmosphere and rivers.
Titan hosts lakes of liquid methane and ethane on its surface. Beneath the planet’s icy surface is thought to be an ocean. New research suggests that Titan may have more in common with Earth than previously thought, at least in terms of seasonal cycles.
Titan looks more like Earth than expected!
Titan is considered potentially habitable. That’s why scientists from Stanford University and NASA’s Jet Propulsion Laboratory continue to research the satellite. Research has focused on how surface features on Saturn’s moon, such as sand dunes and plains, are formed.
In addition to being the only satellite in the solar system known to have a significant atmosphere, Titan also has a seasonal fluid cycle similar to Earth’s water cycle, where liquid flows from the surface and turns into clouds. However, this cycle, which occurs with water on Earth, takes place on Titan with liquid methane and ethane.
This seasonal cycle also explains how sand dunes formed from hydrocarbons are formed. But while the sands on Earth are composed of solid silicate grains, the sands on Titan often have soft components that are easily eroded. How these components turn into the structures that make up the sand dunes has been an unanswered question until now.
The researchers found the answer in a process called sintering, where particles come together into a solid mass due to heat or pressure. This process is thought to keep the particles at a certain size by balancing the wear and tear.
This process, combined with the seasonal cycle on the satellite, also explains the sand dunes that form around Titan’s equator, the plains around the mid-latitudes, and the complex terrains called labyrinths near the poles. Different terrains are made up of different amounts of wind, precipitation, and the flow of rivers that carry the sediment around them. Despite all this and the different components, Titan appears to have a seasonal system quite similar to Earth’s.
