Mars
מצב מפורטאודות Mars
Mars is a world of ancient mysteries and future possibilities. Known as the Red Planet due to iron oxide on its surface, Mars has the largest volcano in the solar system (Olympus Mons) and a canyon system (Valles Marineris) that stretches across the entire planet. Evidence suggests Mars once had flowing water and a thicker atmosphere, making it a prime target in the search for past or present life. Today, Mars has polar ice caps and experiences seasons similar to Earth.
