Mars doesn't have a very strong magnetic field, which suggests that the core of the planet has stop being as active. It also means that some of the atmosphere of the planet has been stripped away! Mars has the biggest known volcano in the solar system called Olympus Mons (it is almost two and a half times bigger than Mount Everst!). It is one of the only bodies in the solar system that we have observed water on! In all these pictures you can see that Mars has a North Pole like we have here on Earth. Recently we have found evidence to show that there was probably once rivers and seas on Mars, does this mean in the past if could possibly have had life on it?!
