CALIFORNIA, iNews.id Mars Rover 2020 will be launched by NASA later this year. The Rover is on the way to the Red planet to search for traces of life.

Scientists do not believe that there is extraterrestrial life on Mars to the present day. But, you think that life exists on the Red planet billions of years ago.

A current study, the observed site-to-site-meteorites ancient earth give us information about how life can thrive there.

“The question that drives our interest is not whether there is life on Mars today. We are driven to ask whether it was life on Mars billions of years ago, which seemed far more likely,” Professor of biogeochemistry leading to the University of California-Riverside-Team Lyons quoted from the Digital Trends Tuesday (3/3/2020).

Lyons and his team want to know how the Mars with water on the surface first, because it is further from the sun than the earth. At this time, the sun does not generate the heat that much.

“The planet is warm enough for the surface of the water, the atmosphere requires a large amount of greenhouse gases, especially carbon dioxide,” says graduate students from the UCR and the author of the companion first paper of this Chris Tino.

There is no way to measure the amount of carbon dioxide, which has always been in the atmosphere of Mars. So, the team is looking for an analog on earth. The team found in the crater of the North linger Ries in Germany, created when a meteorite hit the earth 15 million years ago.

The team explored the crater of the North linger Ries and find the water they contain, the pH-value and the alkalinity is high, a combination that can allow microorganisms to survive,.

“Samples of the rocks of the crater Ries has a ratio of the isotopes of nitrogen can be explained by the material due to the high pH-value. What’s more, the minerals in ancient sediments tell us that the alkalinity is also very high,” said co-author Eva Stüeken, a lecturer at the University of St. Andrews in Scotland.

Recent findings indicate that Mars-like conditions when the concentration of carbon dioxide is very high in the atmosphere. Carbon dioxide high to isolate the planet from the beginning and make it warm enough to have water on its surface.

“Maybe 10-20 years before the samples back to earth for brought. But, to know I’m glad, maybe we have helped define one of the first questions after, these samples are distributed to laboratories in the United States and around the world,” said Lyons.
