These four horizontal panels show the view from the European Space Agency's Huygens probe at four different altitudes, as the probe parachuted to the Surface of Titan, Saturn's largest moon. The images were taken on Jan. 14, 2005. This was the first-ever landing on a world in the outer solar system.
The Huygens probe was delivered to Titan by NASA's Cassini spacecraft. NASA also supplied two instruments on the probe, the descent imager/spectral radiometer and the gas chromatograph mass spectrometer.
