Question
The surface gravity of Titan, the largest moon of Saturn, is 0.135 that of Earth. The atmospheric pressure on titan's surface is 1.6 bar; mostly composed of Nitrogen (N2). The solid ground surface is believed to be mostly water ice (the surface temperature is 95 Kelvin). The Huygens probe, part of the Cassini mission to the Saturn system is still active today, landed on titan in early 2005. The probe was approximately a cylinder 1.5 m in diameter and 0.5 m tall, with a mass of 320 kg.
It was suspected that there are bodies of liquid methane and ethane on Titan's surface; this liquid is likely to have a density of about 500 Kg/m3. The ability to survive landing in such a body of liquid had to be designed into the probe. (We know it did not land in liquid, because there was no "splash" recorded by the onboard accelerometer, but the pebbles in the image of the landing site are rounded, suggesting they have been shaped by erosion by running liquid, as in a stream or on a beach). Such "lakes" were found on the surface of Titan by the Cassini orbiter, though not near the landing site; those "lakes" vary seasonally.
