MARS

Mars, often called the "Red Planet," has a distinctive surface characterized by rugged terrain and a reddish appearance. It is a terrestrial planet, and its surface features include vast canyons, like Valles Marineris, and the towering Olympus Mons volcano, the largest volcano in the solar system. While it does have a surface that we can explore, it lacks the dense atmosphere and abundant liquid water found on Earth, making it a harsh and challenging environment for human exploration.
