An illustration of the descent
While the Cassini probe has been taking the gorgeous pictures of Saturn we know and love
, its little buddy and traveling companion, the Huygens lander
, has been on the surface of the moon Titan. A just-published reconstruction
of what happened when Huygens hit Titan's surface eight years ago gives insight into what the ground on the methane-soaked body is like: something like damp sand, or perhaps crusty snow. According the scenario constructed from its sensor data and on-Earth experiments, when the lander plunked gently down on the moon's surface at a speed of about 10 mph, it sank into the ground about 5 inches before bouncing, sliding a little over a foot, and then rocking back and forth several times before coming to a halt. Earlier reconstructions seemed to indicate that the surface was soft. This version of events, though, suggests that the ...
