Titan is the only moon in our solar system with a significant atmosphere. Now we have a very good idea of how this dense atmosphere formed.
Southwest Research Institute has partnered with the Carnegie Institution for Science to perform laboratory experiments that recreate the conditions of Saturn’s moon Titan in a tiny vial.The experiments corroborate an existing theory regarding the way Titan maintains its dense atmosphere.
The scientific community has taken a particular interest in Titan due to the fact it may have once harbored microbial extraterrestrial life. It is also the only moon in our solar system that has a significant atmosphere.Titan’s mysterious atmosphereFor the SwRI and Carnegie experiments, the scientists set out to better understand how Titan maintains its thick nitrogen-rich atmosphere. The team published their findings in a paper in the journal Geochimica et Cosmochimica Acta.Titan, the second-largest moon in our solar system after Jupiter’s Ganymede, has a denser atmosphere than Earth. Ever since it was first discovered in 1944, scientists have pondered and investigated the evolution of Titan’s atmosphere.“While just 40 percent the diameter of the Earth, Titan has an atmosphere 1.5 times as dense as the Earth’s, even with a lower gravity,” SwRI’s Dr. Kelly Miller, lead author of the paper, explained in a press statement. “Walking on the surface of Titan would feel a bit like scuba diving.”Unsurprisingly, humans wouldn’t be able to survive on the surface of Titan, despite the fact it has an atmosphere. That dense lunar atmosphere is made up of approximately 95 percent nitrogen and 5 percent methane.“The presence of methane is critical to the existence of Titan’s atmosphere,” Miller continued. “The methane is removed by reactions caused by sunlight and would disappear in about 30 million years after which the atmosphere would freeze onto the surface. Scientists think an internal source must replenish the methane, or else the atmosphere has a geologically short lifetime.”Corroborating the replenishment theoryMiller was also lead author for a 2019 paper published in the Astrophysical Journal that proposed a theoretical model for the replenishment of Titan’s atmosphere. In it, Miller and a team of scientists theorized that organic materials are heated up in Titan’s rocky interior. These would then release nitrogen and methane, which seeps out at the surface, forming the moon’s thick atmosphere.A diagram visualizing the organic materials atmospheric reservoir theory.

To do this, they heated organic materials within the vials to temperatures of 482 to 932 degree Fahrenheit at pressures of up to 10 kilobars.As expected, these experiments produced carbon gases like carbon dioxide and methane. They did so in sufficient quantities to be able to supply Titan’s atmospheric reservoir.An artist’s impression of NASA’s Dragonfly quadcopter.

NASA will send a probe called Dragonfly to the Saturn moon in the year 2028. The Dragonfly mission will include a quadcopter influenced by the US space agency’s Ingenuity Mars helicopter. The chopper will explore and investigate Titan’s atmosphere, beaming a wealth of new data back to Earth. Scientists hope they will be able to use this new information to determine whether Saturn’s moon once had habitable conditions.
