"Being off even a little bit represents hundreds or thousands of kilometers in distance on the surface of the Earth."
Mars, often called the Red Planet due to its distinctive rusty color from iron oxide on its surface, is Earth's neighboring planet and humanity's most likely next destination for exploration. It’s about half the size of Earth and takes nearly two years to complete one orbit around the Sun. Mars is home to the largest volcano in our solar system, Olympus Mons, as well as a massive canyon system called Valles Marineris. It continues to fascinate scientists who are searching for signs of past or present life while planning for the day humans pay a visit.
