Why is Mars not qualified to host life on its surface?

A new study has suggested that Mars may not be qualified to accommodate life on its surface, due to its small size, which does not qualify it to accommodate large amounts of water.
And a new study published last Monday in the journal said that Mars lost more water and other volatile substances during its formation than its large neighbor Earth, while retaining more vital molecules than bodies. smaller and drier, like the moon or the asteroid. Vesta.
According to “Sputnik”, Professor Kun Wang, the author of the study, and his colleagues studied the amount of potassium isotopes present in Martian meteorites and used the element as a kind of tracer of the most molecules. volatiles, including water.
They found that Mars lost more potassium and other volatiles than Earth when it was formed, while retaining more vital molecules than smaller, drier bodies, such as the moon or the asteroid Vesta. .
“The fate of Mars will likely be determined from the start, and there may be a limit to the size of rocky planets to hold enough water to support life and plate tectonics, with a mass exceeding the mass of Mars.” Kun Wang said.
“There is no doubt that there is liquid water on the surface of Mars, but it is difficult to determine how much water is available on Mars, solely through remote sensing studies and rovers,” he said. added Wang.
And Wang suggests, “Scientists looking for extraterrestrial life in the future should use the size of the planet as a larger benchmark than previously thought.
Last month, astronomers revealed that regional dust storms play a surprisingly large role in losing water to Mars, warming the cold Martian atmosphere at high altitudes, and preventing water vapor from freeze.
