Huygens Probe landed on Saturn’s moon Titan in 2005. The successful landing indicated Titan’s surface is covered with a powdery substance. Scientists are still analyzing the data the probe sent back to earth. The Cassini-Huygens mission is a joint venture of the European Space Agency, the Italian Space Agency, and NASA. The mission left earth in 1997. The Cassini portion continued to send back data about Saturn and remained active until September 15, 2017. Children can see drawings and more at: Cassini-Huygens.
