A new study has revealed that water on Mars was formed billions of years ago. According to a team of Japanese researchers, water is believed to have originated on the Red Plant at least 4.4 billion years ago. Researchers said that they arrived at this conclusion after analyzing meteorites that came from Mars. The dark meteorites were discovered in the Sahara desert in 2012. The meteorites are called NWA 7533 and NWA 7034. After studying these meteorites, the team got an idea of composition. They said that these meteorites are mixtures of a variety of rock fragments.
An international team of researchers recently acquired samples of NWA 7533 for study. The sample weighed 50 grams. The team drew some exciting conclusions during the study. The mineral composition revealed that water was present on the planet earlier than thought. The composition showed chemical signatures of oxidation. This would have occurred as the water was formed. The said meteorite is very small. It weighs 84 grams. It is believed to be a remnant of a larger meteorite. The rocks would have broken up after entering the Earth’s atmosphere. Researchers said that the Martian rocks are rare. They said that the rock can fetch up to USD 10,000 per gram.
According to several scientific studies, it has been established that water is present on Mars for at least 3.7 billion years. But the latest findings suggest that water on the Red Plant formed around 4.4 billion years ago. The Martian atmosphere was once thicker. But the planet lost its atmosphere to space. The Martian atmosphere is currently very thin. This prohibits liquid water’s existence on the surface of the planet. Researchers said that the latest findings could help answer many crucial questions about Mars and the origins of life beyond Earth. Only four space agencies — NASA, Roscosmos, ESA, and ISRO have got success in putting put spacecraft in Martian orbit. NASA has over the years sent four robotic vehicles to the planet. The agency is planning for human missions to the planet in the 2030
