Nasa’s Perseverance rover has discovered diverse organic matter that could be evidence of life in the Jezero crater on Mars. The findings imply that a more complicated system than previously assumed occurred on Earth in the past.

Researchers propose a variety of possibilities for the origins of biological stuff on Mars. Water-rock interactions and deposits by interplanetary dust or meteorites are examples, while biotic origins generated from live creatures have not been ruled out.
Understanding more about Martian organic matter, according to the study, could give light on the availability of carbon sources, with consequences for the search for potential evidence of life.

The rover’s Scanning Habitable Environments with Raman and Luminescence for Organics and Chemicals (Sherloc) instrument is the first on Mars to enable fine-scale mapping and analysis of organic compounds and minerals.

In February 2021, Perseverance landed within the Jezero crater, the site of an ancient lake basin with strong potential for previous habitability. Scientists have been examining the geological make-up of the crater floor since then, using an array of equipment on board the rover that can photograph and analyse the rocks.
