The Martian crater Jezero was definitely a lake full of organic matter

In the first 208 days of Perseverance’s stay on Mars, NASA was able to obtain an enormous amount of information about Jezero Crater, the exact location where the rover landed, in February 2021. Today we can say, with certainty, that the aforementioned crater was a An ancient lake containing organic molecules.

Be careful to assume that the presence of organic molecules definitively means that there is life on the Red Planet; However, locate them It makes the possibility more likely. From the data obtained, it was found that the Jezero crater has an embankment contaminated with igneous rocks, that is, formed by magma, which in turn could be related to volcanoes or meteorite impacts. Experts say that the properties of rock materials have passed of water changes.

It appears that Jezero Crater is indeed what we suspected based on orbital imaging. she was Lake about three and a half billion years ago. And that’s really exciting for us, because at the time of liquid water on Mars, life on Earth was evolvingSo says A IFLScience Dr. Joseph Raziel Hollis, Del Natural History Museum from London.

Now it remains only to understand whether you are The basic building blocks of life.

Scientists were able to analyze the mineral composition of the Jezero pier thanks to Scanning Habitable Environments with Raman and Luminescence for Organics and Chemicals, or simply SHERLOC. It’s a tool that’s included in the rover perseverance able to discover fluorescence from specific compounds organic In rocks rich in olives.

It is possible that these are the building blocks of life, but we won’t know for sure until we can analyze these samples in more detail.Dr. Hollis explained.

test tube samples It will be returned to Earth from the mission Mars sample returnto study it in more detail. Only then can we say with certainty that Mars once harbored life. Evidence that the Jezero crater was a lake with its own organic particles led to further observation: sedimentary rocks were also identified in the large Gale cavity, very far from the first. This strongly indicates that the molecules are organic It was popular on the planet.
