Mars Had Once Water on Its Surface

Researchers recently found out that there were two unique reservoirs of ancient water that once existed on the surface of Mars. We know that it is hard to believe, we did not believe it at first, either, but the Red Planet was once wet. Can you believe that?

Jessica Barnes, from the University of Arizona, stated: “A lot of people have been trying to figure out Mars’ water history, like, where did the water come from? How long was it in the crust of Mars? Where did Mars’ interior water come from? What can water tell us about how Mars formed and evolved?”

They studied samples

These are some essential questions to answer. Barnes, together with her colleagues, has taken a look at the isotopes of hydrogen, which were locked inside the rocks found on Mars. Isotopes are some variants on an element that has different numbers of neutrons in their composition. They studied all the samples they got, which they knew originated from the crust of the Red Planet, such as Allan Hills and Black Beauty meteorites.

So, where did all the water come from?

There are two different types of Martian volcanic rocks that contain water, which is enriched shergottites and depleted shergottites, that have various hydrogen isotope ratios. Their results show that Mars got the water from two large sources in its early history. They found out that the variability suggested that Mars, which we know that it differs quite a lot if we are to compare it to Planet Earth and the Moon, did not really have an ocean of magma surrounding the entire planet.
