NASA’s Cassini spacecraft deployed a lander called Huygens to Titan’s moon on December 25, 2004, a European spacecraft that moved on a trip to the Saturn system with the Cassini spacecraft. Huygens was off during the seven-year trip, but its internal timer told it that It begins its work before entering Titan’s atmosphere.
According to the “Space” website, following Huygens separated from the Cassini vehicle, it took three weeks to descend to the surface of Titan, one of Saturn’s moons, and it landed on January 14, 2005.
The spacecraft spent two and a half hours skydiving through Titan’s atmosphere and transmitting data to Cassini, which transmitted that data back to Earth.
Huygens sent back the data following it landed, and for another hour and a half before its batteries ran out, the data and images from Huygens revealed that Titan is one of the most Earth-like places in the solar system.
The moon has a thick atmosphere made of nitrogen and methane, and is covered in lakes of liquid methane. Huygens even found organic molecules on Titan.
Scientists now believe that Titan may be the best place to search for life in the solar system.
