Some views of the rock Cheyava Falls with spectroscopic results (d) from the examination of samples from the area

An article published in the journal “Nature” reports the results of the analysis of data collected by NASA’s Mars Rover Perseverance on the rock nicknamed Cheyava Falls. Perseverance found it in 2024 in the Neretva Valley during its journey within the Jezero Crater on Mars. The rock immediately attracted great interest because it contains chemical signatures and structures that could have been generated by ancient Martian life forms.

A team of researchers confirmed the exciting results presented last year and concluded that these are potential biosignatures. This means they provide clues to the possible presence of Martian life forms in the past, but further studies are needed to obtain definitive answers. In fact, the presence of organic compounds and iron minerals such as vivianite and greigite could also be due to abiotic reactions.
