Recent study by the scientists in London has revealed that rocks formed in lake beds may prove the existence of life on Mars a billions of years ago.
Mars has always been a subject of curiosity for scientists all around the world and so has the presence of primitive life forms on it been a subject of debate but a new study could prove helpful in tracing the tiny life form known as microbes.
According to Sean McMahon, a Researcher from the University of Edinburg in Britain, Mars is full of interesting rocks and minerals and the sedimentary rocks made of compacted mud or clay are the most likely to contain fossils. These iron rich rocks help preserve the fossils. Mars in the Noachian and Hesperian Periods between three and four billion years ago was covered with water, which could have supported life.Mars as a planet is not affected by tectonic movements. As a result the fossils are better preserved than those on Earth.
The team of scientists studied the fossils found on earth and compared them with the lab results replicating Martian conditions and found out bankable locations on the Red Planet to look for signs of ancient life. The outcome could help NASA’s next rover mission to the Red Planet, which will focus on searching for evidence of past life.The US space agency’s Mars 2020 rover will collect rock samples for upcoming research. The European Space Agency is also planning a similar mission in coming years.
The recent study of Martian rocks could help the both missions and the identification of the best places to gather rock samples.
