Titan is Saturn’s largest and weirdest moon. In fact, it’s more like a planet: Titan is the only moon in the solar system with an atmosphere, and it has a gravity that is similar to Earth’s. It even has lakes and rivers—except on Titan, the “waterways” are actually liquid methane and ethane (liquid because the surface is very cold, minus-291 degrees Fahrenheit).
Perhaps the most interesting thing about Titan is that organic compounds like hydrocarbons exist there, which means the moon contains materials that could make up life. Any life-form that might exist on Titan, though, would likely look like nothing we can imagine. To date, only one spacecraft has ever been near this special moon, and that is NASA’s Cassini mission, which ended in September 2017.
In 2024, NASA will send a mission to Titan called Dragonfly. This dual quadcopter will descend onto the moon’s surface and fly around in search of evidence of habitability.
