The Cassini spacecraft has captured spectacular footage of gigantic methane clouds swirling over Titan, Saturn’s largest moon.
Cassini is on the final stage of its 20-year long spacefaring mission to the farther reaches of the Solar System. The probe captured the footage during its final orbit of Saturn and Titan.
Saturn’s largest moon is an inhospitable world, about 50% larger than Earth’s own satellite, and the second largest in the Solar System. It orbits Saturn once every 15 days and 22 hours. Scientists believe that Titan holds massive amounts of liquid hydrocarbons, amounting to more than the known oil and natural gas reserves here on Earth. During an earlier fly-by in 2013, Cassini beamed data back to Earth that enabled astronomers to elucidate that Titan’s deep canyons were carved by liquid methane.
Titan and Earth are similar in many ways, in fact. Both worlds have seas and rivers, and a rain-producing atmosphere. The major difference is that while liquid water flows through our planet’s river systems, Titan’s are filled with a dark fluid that scientists believe to be liquid methane.
Cassini’s final journey will take place on September 15 this year. The craft will fly straight into Saturn’s atmosphere, where it will burn up in a blaze of glory. By then, Cassini will have completed an epic voyage of some 2.2bn miles across known space.
