Mars is the planet that is half the size of the Earth, has two moons, and has an atmosphere of mostly carbon dioxide. It is also the planet that many scientists have made space explorations with next to the moon.This is because they believe that this closest planet has reserves of water and can be cultivated to become a habitable planet as well.
