Something interesting about Mars is that it is home to the highest known mountain in the entire Solar System which is Olympus Mons. This volcano is more than three times higher than the tallest mountain on the Earth which is Mount Everest, Olympus Mons is so tall that it nearly reaches the top of Mars’s thin atmosphere. There is no liquid water on Mars but there are two polar ice caps made of large amounts of frozen water and sometimes there are even clouds made of water vapour much like on Earth. A day on Mars is very close to the same length as day on Earth, Mars rotates in 24 hours and 37 minutes which is only about 2.7% longer than the Earth does. Because Mars is farther from the Sun however, Mars takes much longer to travel once around the Sun than the Earth does, Mars takes almost 687 Earth days. Because Mars is so close to the Earth and is so similar in some ways people have wondered for a very long time if life could survive there or if something lived on Mars already.
Modern astronomers have not found any signs that anyone or anything has ever lived on Mars, if there was ever life on Mars it was probably only small simple kinds of life like bacteria. Now people are wondering if Mars could be made into a good place for humans to live. More than 50 space missions have sent to or close to Mars to gather more information about this fascinating red planet, there are currently 5 orbitors circling Mars and 2 rovers exploring it’s surface namely Curiosity and Opportunity rovers all sending data back to Earth. People want to try to go to Mars someday and it may even happen in next few decades, until then there is always more to learn about this exciting planet.
