Martian meteorites reveal secrets on the red planet!
Meteorites exploded on the surface of Mars when an asteroid hit the red planet 11 million years ago, revealing a flowing stream of water under the surface of Mars one day.
A group of these meteorites landed on Earth in 1911. The nakhlites were named after El Nakhla in Egypt, where the first fell.
Researchers from the Universities of Glasgow, Leeds, Uppsala, De Pisa, New South Wales, Curtin and the Oxford Center for Nanoscale Analysis examined two samples of nakhlites, one in the Miller Mountain Range in Antarctica in 2003. The second was found in the collection of rock samples from the University of Bordeaux. , 1931.
Today, planetary scientists at the University of Glasgow have used a new technique to analyze these nakhlites, claiming to have shed light on the process that generated liquid water on Mars.
"What we have seen is that the model of deformation in minerals exactly matches the distribution of spoilage veins, formed from Martian fluids," said Dr. Luc Daly, Associate Researcher in Solar System Science at the Faculty of Earth Sciences.
The analysis reveals that an asteroid hit Mars 633 million years ago and formed a massive crater in the volcanic rocks at the surface of the red planet, producing a significant effect sufficient to make Melt the ice below the surface and quickly cross modern cracks that are actually a temporary thermal system beneath the planet. Red, which changed the mineral composition in the rocks, according to Dr. Daly.
Another asteroid, which hit Mars hundreds of millions of years ago (11 million years ago), blew rocks on the surface of the planet to begin its long journey into the world. space towards the Earth.
The research team is convinced that the results provide new insights into the configuration of Mars' global landscape.
The regular effect of asteroids can have similar effects on the ice beneath the surface throughout the planet's history, creating temporary hydrothermal systems across the planet and significant water sources liquid.
The analysis also provides important clues that can help determine where nakhlites originate from Mars.
The study, funded by the Science and Technology Facilities Council (STFC), was published in the journal Science Advances.
