Reference News Network December 22nd reported that British media said, University of Oxford 
researchers believe that: when the surface of Mars is absorbed into the shell of Mars, Mars is 
not suitable for living.
According to the report of the independent website in December 20th, the latest research led by 
the Department of Earth Sciences, University of Oxford, provides insight into the subtle changes 
in the planet's environment. The planetary environment determines whether the planet is likely to 
have life.
Until 3 billion years ago, the surface of Mars was covered with water, almost the same as the 
earth. But now, Mars is barren and arid, so the Martians do not exist except in science fiction.
Researchers have long been thinking about what has happened to the water on Mars. Previous 
studies have shown that a portion of the water on Mars was absorbed into space after the Martian 
magnetic field collapsed.
However, a recent research carried out by University of Oxford researchers shows that water is 
still there, but it has been locked on the surface of Mars because of its chemical reaction with the 
Dr Wade, the leader of the study, said: "on Mars, water reacts with the lava that has just erupted to
form a basalt shell, producing a sponge effect. "The study was published in the journal Nature.
"The reaction between water and rock changes rock mineralogy, causing the surface of the planet 
to be dry, so it is not suitable for life," he said. "
The tiny difference between the earth and the other planets of the solar system, such as Mars, 
has created conditions for life on our planet, not other planets.
Dr. Wade said: "the biggest difference is that the surface rock of Mars contains more iron, 
because Mars is formed under more oxidizing conditions. "
Researchers found that the rocks on Mars lock up 25% more water than the earth's rock, and 
then the rocks transfer the water to the planet.
For a long time, it has been thought that Mars may have life, paying special attention to the water 
content of Mars.
Previous studies have found that the structure of Mars suggests that the surface of its surface 
might have had microbes at one time, perhaps in the once hot springs and intermittent fountain.
Professor Jim McElwain, a researcher at the Durham University, pointed out that although Mars 
does not have water like the earth, even today it has not completely dried up. Meckel Wayne 
studied the possible existence of water in Mars, but did not participate in the study.
"We know that Mars had had a lot of water before, billions of years ago," he said. But we also 
know that there's a lot of water now, in the ice. "
Professor McElwain said that although Mars rocks may absorb moisture, even if there is no such 
phenomenon, Mars probably will not have such an ocean like the earth, because its atmospheric 
conditions are different.
"Water is probably the most end to ice, or into space," he said. "
But Dr. Wade said it was important to explore the role of rock chemical components on other 
planets in locking water and changing the environment.
Small chemical changes in the planet may have a significant impact on their ability to maintain 
"These effects and their implications for other planets have not been explored," Dr. Wade said. "
