Study reveals why Mars lost all its water while Earth retains it
Billions of years ago, the Red planet probably had a water cycle of its own. However, experts believe that it would have been very different from the one that operates on Earth.
Researchers at the Moscow Institute of Physics and Technology and the Max Planck Institute for Solar System Research have devised a gadget that depicts how water vapour moves through the Maritan atmosphere which is different from the Earth which involves evaporation followed by condensation and rainfall that complete the cycle.
Paul Hartogh of the Max Planck Institute for Solar System Research explained that the water on Mars has been lost over time and very small amount of frozen water remains on the surface and in the atmosphere in the form of water vapour. The middle layer of Mars is ice cold and allows water to transpire in certain areas at certain times of the year. This phenomenon reveals how the planet revolves around the Sun during different seasons. The study also reveals that the planet’s atmosphere is porous which gives enough explanation about how and why all the water on the Red planet got lost over time although the Earth has retained it.
