Mars used to look like Earth with oceans, lakes, running rivers and rainfull, research suggests.

The US study concludes that the Red Planet’s surface was once far more watery than previously thought.

Experts said the study bolsters the idea that Mars once had a warmer climate, and recyled its water – evaporating it from the ocean and returning it to the surface as rainfall.

Scientists measured the volumes of Martian valleys and found the amount of water on the planet’s surface was 10 times greater than previously thought.

And researchers found the amount of water needed to carve the planet’s waterways was 4,000 times the volume of the valley cavities.

This suggests Mars recycled its water — evaporating it from an ancient ocean and returning it to the surface as rainfall.

  1. I find this an utter impossibility as mars does not have enough mass to hold down water through what we call gravity. Earth is twice the size of mars and the perfect mass such that it allows methane and ammonia weighi 16 and 17 atomic weights to escape to the upper atmosphere and away, while water weighing 18 is just heavy enough that it falls back down in the rain cycle – producing a ripe environment for life to exist. Mars is not massive enough to hold down or attract the rain to fall.
    The better explanation of the surface features on Mars has been explained by “the Electric Universe Theory” by Wallace Thornhill, a plasma physicist from Australia and the thunderbolts project. Please look into it for a Far better explanation of Mars surface features.

    • Mars’ lower mass doesn’t mean it never had water. Remember, they have already found water on Mars, albeit in small amounts. It could have had a lot from the early formation of the solar system, then slowly lost it over time, in part because of its lower mass.

      I think the EUH has interesting ideas and may be correct in some cases about the features on Mars, but it is certainly plausible that water is responsible for many of those features as well.
