Water on Mars. The lowland areas of Mars are covered in a blue sea. Mars' two moons, Phobos and Deimos, are seem crossing the planet in that order. It is thought that liquid water did exist on Mars millions of years ago, but it is now too cold and has too little atmospheric pressure to possess liquid water. It has been suggested that the planet could be erraformed"", made more Earth-like, for human habitation by centuries of climatic engineering." | |
