Mars has been covered by water like Earth

Mars was once covered by water like ours today, according to research by scientists at Georgia Tech University (USA).

One of the reasons water cannot exist on Mars today is because the red planet's density is only 1% of Earth's. However, scientists at Georgia Tech University have discovered that the planet's atmosphere is 20 times thicker than it is today.

Professor Josef Dufek and colleagues conducted research on material samples on the surface during ancient volcanic eruptions on Mars, thanks to the help of Spirit probes launched by NASA on red planets in years. 2007.

Water may exist on Mars in the new era

Scientists analyzed rock fragments shot into the atmosphere when a volcano on Mars erupted about 3.5 billion years ago. With the help of the Spirit ship, the team was able to observe the remnant rock and measure the size, depth and subsidence of the surface at the location of the falling rocks.

Later, the team created a similar subsidence on Mars by firing particles the size of rock pieces found by the Spirit probe on the red planet. Scientists calculate that to recreate subsidence, molecules must fall in an atmosphere 20 times denser than today's Mars atmosphere.

This proves that Mars once had an atmosphere much thicker than it is today. This means that the surface of the red planet can contain water - one of the important factors for life to grow.

"Our research shows that early Mars was a world covered by water with a much thicker atmosphere than we know today," said Dr. Josef Dufek, head of the team. Research, said on the Telegraph.

An earlier study also found plaster on Mars - a sign that water once existed on the red planet. Because gypsum can only form when water is below 60 degrees C.
