Huygens descending with parachute
The Huygens probe descending onto Titan on 14 January 2005 with the first of its three parachutes open. During the descent, the probe encountered winds of different speed.

Global map of temperature and surface pressure during Huygens de

These panels are the result of a simulation run with a Global Circulation Model and based on data gathered by Huygens. The panels provide an instantaneous global map of temperature (first three rows) and surface pressure (last row) for the time of the probe’s descent onto Titan.

The temperature maps were simulated for different altitudes: 4.5 kilometres, 300 metres, and ground, respectively. The pressure is simulated for the ground level. The left column shows the results taking into account Saturn’s tidal force, the right column the results without Saturn’s tide

Simulation of temperature maps of Titan at different seasons

These panels are the result of a simulation run with a Global Circulation Model and based on data gathered by Huygens. They show a vertical cross-section of temperatures in the meridional lower atmosphere (at different altitudes) of Titan, during day time. ‘Ls’ (on the image) is the solar longitude describing the season. The temperatures are expressed in Kelvin (0 K= - 273.15 °C)
