Mars’ poles contain millennia-old ice deposits. They also contain carbon dioxide, iron, aluminium, silicon and sulfur, which could be used to make glass, brick and plastic. Furthermore, the planet’s atmosphere contains enough hydrogen and methanol for fuel.
The tallest mountain on Mars and in the solar system is Olympus Mons, and it is two and a half times taller than Mt. Everest. A Martian canyon system, called Valles Marineris, is the length of the entire continental United States and three times deeper than the Grand Canyon.
Mars Colony: Location, Location, Location
The first step to building a colony is to figure out where the best chance of survival is. For Mars, some researchers have identified the planet’s poles, which contain millennia-old ice deposits. These are thought to contain large amounts of ice, which mars settlers could extract and turn into liquid water.
