Rivers have flowed on two other worlds in the solar system besides Earth: Mars, where dry tracks and craters are all that’s left of ancient rivers and lakes, and Titan, Saturn’s largest moon, where rivers of liquid methane still flow today.

A new technique developed by MIT geologists allows scientists to see how intensely rivers used to flow on Mars, and how they currently flow on Titan. The method uses satellite observations to estimate the rate at which rivers move fluid and sediment downstream.

Applying their new technique, the MIT team calculated how fast and deep rivers were in certain regions on Mars more than 1 billion years ago...

What are the hydrocarbon seas on Titan really like? While the upcoming Dragonfly helicopter mission to Saturn’s hazy and frigid moon should arrive by 2034 to explore Titan’s atmosphere, the need remains for a mission that could study the moon’s mysterious seas and lakes, filled with liquid hydrocarbons.

But how about an aircraft that could study both the seas and skies of Titan?

A new mission concept that received funding from NASA’s Innovative Advanced Concepts (NIAC) Program is called “TitanAir,” and features a flying boat, known as a laker...

Lakes on Saturn’s moon Titan, composed of methane, ethane, and nitrogen rather than water, experience density driven stratification, forming layers similar to lakes on Earth. However, whereas lakes on Earth stratify in response to temperature, Titan’s lakes stratify solely due to the strange chemical interactions between its surface liquids and atmosphere, says a paper by Planetary Science Institute Research Scientist Jordan Steckloff.

Stratification occurs when different parts of a lake have different densities, with the less dense layer floating atop the denser layer...

Researchers report significant seasonal variation in Titan’s energy budget – that is the amount of solar energy absorbed by the celestial body and the thermal energy it emits. The findings, reported in the journal Geophysical Research Letters, could lead to new insights about climate on Earth.

Titan is the only body in the solar system, other than Earth, with a significant atmosphere and liquid surface lakes. “By studying Titan, we can learn a lot about Earth,” said Ellen C...
