Humans have long been fascinated with our closest rocky neighbor. Christiaan Huygens was the first person to draw detailed maps of Mars in the 1600s using a telescope of his own design. H.G Wells wrote a groundbreaking novel in 1898 featuring visitors from Mars called War of the Worlds. Both the former Soviet Union and the United States have landed probes on its red, rocky surface. Our search for life outside Earth draws us to Mars and despite the lack of evidence of life so far, humans are determined to set foot on the planet itself.
