An ancient collision with a massive asteroid can explain the topography of Mars
The origin and nature of Mars remain a great mystery to us. The surface of the Red Planet is distinctly divided into two hemispheres with different types of terrain: smooth plains in the north and strewn with craters of the highlands in the south. In addition, Mars is accompanied by two small moons having very unusual shapes - Phobos and Deimos. In a new study conducted by a research team headed by Professor of Colorado University in Boulder, USA, Stephen Mojzsis, it is assumed that all these features of the Red Planet can be explained by the hypothesis of an ancient giant collision with an asteroid.
