The fact that the water on Mars had a salty taste rich in minerals was the fact that Keisuke Fukushi, an associate professor at the Center for Environmental Studies in Japan, Kanazawa University, Professor Yasuto Sekine of the Institute for Global Life Sciences, Tokyo Institute of Technology, and Robin of Harvard University, USA.・ It was found by the water quality restoration by the research group of Associate Professor Wordsworth and Senior Researcher Hiroshi Sakuma of the Materials and Materials Research Organization.
According to the Tokyo Institute of Technology, research on orbiting satellites and rover confirms that liquid water was present over a wide area in the ancient times about 40 to 35 billion years ago.NASA's Rover Curionty is a Gale Crater, which is said to have had a huge lake inside about 35 billion years ago. Discovered the minerals and organic matter produced in.
When the research group restored and analyzed the exploration data using a new technology developed in the field of radioactive waste treatment on the earth, the water that once existed on Mars was about one-third of the seawater on the earth. It was revealed that the pH is neutral and rich in minerals and energy.
Mars has been attracting attention as to whether it was the environment in which life was born, but until now, the salt content and pH of water were unknown.The results of this research confirmed that ancient Mars was a suitable environment for the birth and survival of life.
The research group believes that the results of this research will lead to the elucidation of new mysteries such as whether the environment suitable for life on Mars has spread over a wide area and when and how that environment ended.
