Mars Cold Lake Two Detective, with a new thing, what is it?

The "cold lake" in the two -level Mars may be just frozen

A new study found that the frozen soil adjacent to the Antarctic point of Mars has caused radar reflex signal snowflake screens.

In December 2012, the European Airlines Agency Mars Express found that this picture was white, which showed that the ice crown of Mars Antarctic point consists of ice and dry ice.

A new study found that the radar shows that the highlights of the Mars Antarctic's highlights may not be the groundwater that was originally expected but frozen soil.

For decades, scientists have been suspected of having water hidden under the Martian polar ice cover, like the earth. Since 2018, the researchers searched for the dark lake adjacent to the Mars Antarctic ice cover with the sound of Marsis on the Marsis low -frequency radar on the Mars Express. By 2020, they found some signals of brine marks. Water relics. These traces may have a life body, and it is still possible now, scientists wrote.

Currently at the University of York, Toronto, planetary scientist Azetus Smith and his colleagues are studying a project: how much calories and halogen need for liquid water for the formation of liquid water in Mars.

The York University team believes that if it was not for the search for Mars Lake, the pottery on Mars would not explain the radar snowflake screen. Smith told Space.com: In the Mars research circle, there has always been doubt about the media of Mars, but no one can give an exact answer. Therefore, when the radar snowflake can be explained, that material should be there, which is exciting. I love puzzles, and Mars is the mystery in the mystery.

The pile of substances that scientists are concerned are called Mongolian Basilica, a compound that is closer to pottery than volcanic rocks. It is made of erosion and water from volcanic rocks. Their team mentioned.

Mongolian Shishi is a rich thing in Mars and is distributed in the south. "It can be mainly distributed on the earth in Central America or Alaska, and there are no other continents." Smith said.

In the laboratory, the researchers cool the soapstone at minus 45 (-43 degrees Celsius), maybe there are similar cooling materials on Mars. The moisturizing mask stones can make the Marsis radar (superficial layer and ionizing layer exploration radar pension simplified version). Even if other substances are mixed, the focal length can be brighter.

Smith and colleagues analyzed the visual infrared analysis of Mars Antarctic point, and they found the Monomo Stone. They speculate that the Monoval Stone at the Antarctic point of Mars is formed in the mild period. This area was covered by water, and the trace pit was later hidden behind the water.

The color point has always been covered with the snowflake screen of the Antarctic point area. It has always been believed that it is the liquid water on the superficial layer, but now its extensive distribution is considered to have something on the cold surface.

If time goes back, Mars may become more humid, and the existing evidence shows that there is a large area of ​​liquid water outside that area. Smith said that the mask stones adjacent to the Antarctic point of Mars may have enough time and temperature to support liquid objects.

In summary, the researchers believe that the place where the radar display is white, soap stone is more common than brine traces.

Science is a process, and scientists often get closer to the truth. Smith said that radar shows other substances of non -liquid water, which does not mean that the results of the initial publishing research in 2018 were ineffective. It gives people new research methods, model data and observation results. These useful things are inclusive in Mars research team.

In the future, I am willing to experiment with different clay at a lower temperature. I suspect that other clay has different reactions, so that we can find them better.

Mars is the fourth -closure planet from the sun, and is also the second small planet after Mercury in the solar system. It is one of the four planets in the solar system. Western is called Mars in the West, and is the God of War in Roman mythology, so in English, Mars is the meaning of the Roman God of War, which is usually called "red planet"; in ancient Chinese, it was like fire, and the position and brightness were often. The change makes people elusive and calls it confused.
