Meteorite Reveals Clues Regarding How Mars Lost its Atmosphere
A meteorite discloses hints regarding the loss of atmosphere on Mars. Mars has lost its thick, carbon dioxide-rich atmosphere and has turned into a cold, rocky and desert planet, revealed researchers.
They say that the Lafayette meteorite gave indications of carbonation. In the process, minerals take away CO2 while reacting with water. Mars lost its shielding blanket about 4 billion years ago. This may have happened due to loss of its magnetic field, space impacts or chemical processes. The main reason behind this can be Carbonation.
The same phenomenon occurs naturally on Earth and this technique has been proposed for mitigating climate change. This can be done by capturing CO2 present in the atmosphere.
The 4.5cm Lafayette meteorite was discovered in Indiana, US in the year 1931. This fell on the Earth about 3,000 years back. It was formed in the crust of the Red planet for about 1.3 billion years ago. It came out from the surface by a massive collision.
Microscopic examination on a part of the rock was done by a team from the Scottish Universities Environmental Research Centre (SUERC). This rock was borrowed from the Natural History Museum in London. A Scotland-based team of researchers examined a meteorite from Mars. They were hoping that they would learn how to deal with changing climate on Earth.
