After planning for Jupiter's moon Europa in 2020, NASA like to explore another. The Saturn's largest moon Titan would be next target.

According to Phys, the text target of NASA for a planned exploration is the Saturn's largest moon Titan. Besides, Titan is the second largest moon next to Jupiter's Ganymede with a measurement of almost half the diameter of Earth.

NASA revealed that until the Cassini mission, years ago, little would be known about Titan. That last mission discovered the nitrogen-rich atmosphere of the moon, its size is almost the same as planet Mercury, seasons, seas, deserts and more. However, what might be beneath the atmosphere and smoggy clouds of Titan is still unknown.

Titan is a tidally locked moon to its planet, Saturn and orbiting every 15 hours and 22 days. Before it was first explored in 1980, Titan was thought to be the biggest moon that can be found in the solar system. Up until NASA Voyager had explored its thick atmosphere for the first mission that at the same time revealed its real size.

Compared to other moons, Titan grabs the most interest of astronomers for its different kind of atmosphere which is 1.45 times the atmospheric pressure on earth. Moreover, Titan has an incredibly different temperature of almost -180 degree Celsius. This temperature is twice colder than the lowest ground temperature recorded on Earth.

Additionally, Titan has a poisonous atmosphere that is filled with nitrogen with some amount of hydrogen and methane mixing out. On Earth, these atmospheric contents are deadly to human lives.

NASA Pioneer 11 first explored the Saturn's largest moon Titan in 1979 which was followed by NASA Voyager 1 and Voyager 2 in the next consecutive years. To record, the Voyager 1 had a closer look at the Titan and helped scientists in measuring its atmosphere, mass, and size. Last is the NASA Cassini spacecraft in 2004 which recorded most of Titan's incredible details.
