Landing on Titan's surface, another view

In this artist rendition, the Huygens probe is about to reach the surface of Titan, Saturn's largest moon.

Because it's in a deep freeze state, Titan's atmosphere is thought to contain chemicals similar to those found on Earth's early days. Data from the Huygens probe combined with Cassini's measurements may offer clues about how life began on Earth.
