Wow! Huygens Lands on Titan

History was made today when the European Space Agency's unmanned Huygens probe landed on Titan, a moon of Saturn that scientists hope hold some of the building blocks of organic life. Launched in 1997, Huygens rode piggy-back on NASA's Cassini probe for seven years on the trip to Saturn before deploying and landing on Titan earlier today. While the Voyager space probes launched in the 1970's have reached the edge of the solar system, the Huygens probe at Titan marks the farthest point from Earth where a human probe has landed.
