Learn about the fascinating features of Mars, from its canalis (water channels) to the giant Tharsis volcanoes and the unique characteristics of its two moons, Phobos and Deimos. Early Earth-based observations revealed the potential for ancient water flow, while the Viking and Pathfinder missions provided critical insights into the Martian surface. Despite its barren appearance, researchers are investigating the possibility of microbial life, spurred by controversial discoveries from meteorite samples. Join us on a journey through the wonders of the Red Planet!
