The European Space Agency's Huygens probe descent sequence from the Cassini spacecraft to Saturn's moon Titan in January 2005. Scientists reconstructed the chain of events from the landing by analyzing data from a variety of instruments that were active during the impact and found that the spacecraft, bounced, slid and wobbled its way to rest in the 10 seconds after touching down on Titan.
