Did the ocean on Mars get into the rock?

Mars has always been the most noted planet since humans discovered it. It is believed that up to 3,000m deep. But where have they gone now?

The great migration from Earth to the red planet will only be a remote prospect if water and air , two important elements for human life, do not appear on Mars as it is now.

3 billion years ago, Mars was once a warm planet with rivers and oceans. There is no scientific consensus that there is so much water on Mars, but popular belief is very much.

The question is, where has that huge amount of water gone after all this time?

Scientists from Oxford University (UK) recently proposed a new, more shocking hypothesis: sucked into stone.

Two hypotheses

Dehydration is one of the main reasons why Mars can't live, regardless of its atmosphere and temperature, says Professor Jon Wade, the lead researcher.

Water has appeared and appeared on Earth about 4.4 billion years when our planet began to cool down, based on scientific evidence found from minerals called zircon , Mr. Wade solved. prefer.

But Mars seems to have lost water quite quickly, only about 1.5 billion years after it was formed.

Some scientists believe that water on the red planet has been sucked into space when the magnetic field of Mars collapsed.

According to Prof. Wade, Mars is about 50% smaller than Earth so it will cool faster, both on its surface and its metal core. A planet with active magnetic fields thanks to the high temperature core. But because Mars' core cools so quickly, the magnetic field finally disappears and the planet begins to be influenced by solar super typhoons, the atmosphere is "swallowed".

Other scientists believe that Mars's water is actually located beneath the surface of the planet. The loss of magnetic fields caused Mars's atmosphere to thin, thus losing its ability to retain heat, thus freezing.

The magnetic field helped the Earth escape the attack of the Sun storms - (Screenshot).

World of water in the rock

In 2015, the US Aeronautics and Space Administration (NASA) proudly announced that the country is still present on Mars. While NASA could not prove it true, the agency confirmed that its Mars Reconnaissance Orbiter, orbiting around Mars, had found signs of a liquid leak in a way. Cycle along the cracks of Mars volcano.

NASA claims these fluids appear only at warm temperatures, equivalent to spring and summer on Earth. The detection of salt in the above fluid lines confirmed the existence of salt water.

In other words, there used to be a sea on Mars, but where did they go?

The Oxford University team believes that the answer lies in the mineral composition of Mars , using models commonly used to analyze rock specimens on Earth, Professor Wade's group concludes the basalt rock above. Mars can absorb 25% more water than Earth's basalt.

"Martian chemical rocks have reacted with water on the surface, forming hydrophilic minerals. Over time, the water gradually recedes into these minerals, leaving a barren surface with only rocks. That means the water is still on Mars, deep inside the rocks, " said Wade.

Prof. Wade's group, though not refuting the previous two hypotheses, believes that mineral water is the main reason why most of the water on Mars disappears.

Has life ever appeared on Mars?

Theoretically, Mars had enough favorable conditions for life. Existing surface marks have shown that the planet also had rivers flowing into the sea and warm temperatures for a certain period of time.

This also means that Mars once had a thick atmosphere before it was swept away by solar storms after the planet's magnetic field collapsed.

In fact, the red planet still has a few magnetic fields left, not because of its core, but in iron-containing minerals. But oddly enough, these minerals can only be found in the southernmost part of Mars.

The universe is always a mystery and there are billions of questions that have never been answered or multiplied by what people do not know. Even the Earth, where people are proud that has dominated and discovered almost everything, there are still things we have not fully understood about it.

The first life appeared on Earth probably about 3.5 billion years ago or earlier. The minerals found in Australia have recently shattered people's popular beliefs and popular knowledge. Not one but several original life forms of the original bacteria.

"I believe there have been life forms, of course, miserable on Mars for three or four billion years. If there is still life on Mars today, it certainly won't be on the surface. but in a place that's hard to find: inside the ground! " , Professor Wade said.

Artificial magnetic shield for Mars

Because the magnetic field collapses, dragging the atmosphere and water into space, Mars becomes a planet that cannot support life. But if one day from the school appeared again, what would it be like?

That is the question that motivated NASA to propose a proposal in March 2017: create a magnetic shield for the red planet!

When the artificial magnetic field appears, Mars's atmosphere will be enhanced, helping to protect the planet from solar storms. Once the atmosphere has been enhanced, the temperature and pressure of Mars will change enough to create and store water on the surface.
