How Titan maintains its atmosphere

Scientists have uncovered how Saturn's moon Titan maintains its nitrogen-rich atmosphere. Experiments mimicking Titan's interior show that heating organic materials produces sufficient carbon gases to replenish the atmosphere. Titan's atmosphere is denser than Earth's, despite the moon's smaller size and lower gravity. It consists of 95% nitrogen and 5% methane, which would vanish without replenishment. NASA's Dragonfly mission, launching in 2028, will explore Titan and study its potential for supporting life.
