Wonders of the Solar System of the Namib Desert is compared to what is known of the surface and depleted atmosphere of Mars, and is used to give an explanation of how the Earth maintains its temperature. Cox then explains how the damaging effect of the sun's solar wind is deflected by the Earth's magnetosphere. Next, he discusses the transformative effect of weather on a planet's surface, such as the global dust-storms on Mars or the electrical-storms of Jupiter. The episode continues with an in-depth comparison of Saturn's largest moon, Titan, using data gained from the Huygens probe's January 2005 descent down to the frigid
