NASA discovered organic molecules on the surface of Mars

An important discovery was made by NASA, as the Perseverance spacecraft found in an ancient crater evidence that life once existed on the planet Mars.

The research vehicle detected on the surface of Mars organic molecules, which are considered bio-signatures, as they are chemical compounds that are usually found in ecosystems where life exists.

NASA's rover was exploring Jezero Crater, a 28-mile-wide impact basin located north of Mars' equator. There he collected many rock samples, some of which contained signatures of organic molecules.

In some of the rocks collected by Perseverance, scientists have detected traces of organic molecules, which are composed of carbon, hydrogen, oxygen and nitrogen, among other elements. These chemical compounds, also known as bio-signatures, are commonly found in living systems.

The findings, presented recently in the journal Nature , provide new clues that suggest life may once have existed on Mars. The first impression excited the researchers, but in contrast researchers from MIT in California noted that the existence of biosignatures alone does not conclusively indicate the existence of life on Mars.

Όπως ανέφερε ο Razzell Hollis (Ράζελ Χόλις): “Ει σημαντικό ότι τα οργανικά μόρια μπορούν να δημιουργηθούν και από διαδικασίες που δεν σχετίζονται με τη ζωή, όπως τη γνωρίζουμε, και έτσι τα οργανικά μόρια δεν αποτελούν στοιχεία ζωής από μόνα τους χωρίς επαρκή επιπλέον στοιχεία που δεν μπορούν να εξηγηθούν με μη βιολογικές ή αβιοτικές διαδικασίες”.

For example, the organic molecule methane can be released from many non-biological sources. This includes the eruption of volcanoes, hydrothermal vents, and comet or asteroid impacts.

Nevertheless, Razzell Hollis noted that the discovery of the compounds is still exciting "because they highlight the diversity of organic matter that may have survived on Mars, even after billions of years of degradation."

In addition, the findings help astrobiologists gain more insight into Mars' complex past and future.

Και τέλος πρόσθεσε ότι: «Αν και δεν μπορούμε ακόμα να πούμε με βεβαιότητα εάν ο θα μπορούσε να ήταν κατοικήσιμος κάποτε, οι αστροβιολόγοι πιστεύουν ότι η παρουσία ποικίλων οργανικών ουσιών είναι απίστευτα σημαντική για τη δυνατότητα ενός πλανήτη ή ενός περιβάλλοντος να φιλοξενήσει ζωή».

This is not the first time that Perseverance has detected organic compounds on Mars. And last year, the rover detected signs of biosignatures around the Wildcat Ridge region of Mars using the SHERLOC (Scanning Habitable Environments with Raman and Luminescence for Organics and Chemicals) system.
