It was in the year 2005 when a probe tried to land on Titan. The atmosphere of Titan is known to be murky. The surface of Titan has a thin, hard surface but if other items will be placed on top of the surface, the item will sink. This is one of the main concerns that a spacecraft may have if it reaches the moon of Saturn.
If the spacecraft is too heavy, it will surely be absorbed by the moon’s surface. Titan is still considered as a unique moon. More and more scientists are trying to find as many details as they can about it.
