Saturn’s moon Titan has a thick atmosphere — the only moon in the solar system to have one — stable liquid on its surface, and a landscape of lakes, seas, and dunes. So it's no surprise that astronomers are keeping an eye on Saturn's largest satellite.

Scientists now say the Huygens probe that landed on Titan in 2005 did so with a bounce, slide, and wobble, yielding new clues about its Earthlike terrain.

Meanwhile, a Spanish team has proposed sending a boat-like probe that could paddle or propel itself across Ligeia Mare, a vast, liquid hydrocarbon lake near Titan's north pole. The inspiration for the probe's design includes Mississippi River paddle boats and an amphibious Soviet vehicle with screw-like propellers.
