Descent to Titan
Explanation: Today's descent to the surface of Titan by the European Space Agency's Huygens probe was the most distant landing ever by a spacecraft from Earth. At 10:13 UT (5:13am EST, 11:13 CET), Huygens entered the atmosphere of Saturn's large mystery moon at an altitude of 180 kilometers. Radio astronomers reported detecting signals from the probe indicating that that Huygens began to deployed a series of parachutes to control its 2 hour descent through Titan's dense atmosphere. Huygens' anticipated landing point is marked by a yellow dot in this near-infrared image from the Cassini spacecraft ... but it is not known if a solid or liquid surface awaited it . The outermost of the nested octagons is about 1,120 kilometers across. The outlines are labeled by altitude and indicate areas of coverage by Huygens' imaging instruments during the descent.
