The discovery of organic molecules on Mars

 The presence of molecules containing organic matter and carbon on Mars has been known for several years by data from the Curiosity spacecraft. And now, Perseverance has discovered more organic molecule/compounds in JezeroCrater, adding a new dimension to the story.

• This molecule is “organic” in the chemical sense, containing carbon and hydrogen. There are many non-biological ways to make organic molecules.
• Looking for evidence of life on Mars has entered an interesting new development from the past to the present.
• Researchers working on data sent from NASA’s Curiosity spacecraft have discovered evidence of an organic molecule called thiophene.
• The researchers do not claim to be evidence of life, but there is no doubt that this discovery is intriguing. This discovery is “consistent with the early life on Mars.”Organic matter was identified with the help of one of the perseverance devices, the Raman & Luminescence scanning habitat for organic matter and chemicals, or SHERLOC.

This instrument uses Raman spectroscopy to measure rock contents. This technique investigates how a sample diffuses light by irradiating it with visible light or near-visible light.

• However, although organic matter in Martian rocks seems to have been spontaneously created without the help of living organisms, these compounds remain important for life exploration on Mars.
• Interestingly, Martian thiophenes is that sulfur must be nucleophilic for thiophenes to be produced by geological processes. However, most sulfur on Mars is non-nucleophilic. TSRs can reduce them to nucleophilic sulfides, but BSRs do the same.
• Currently, six of the maximum 43 tubes are filled and sealed. Four are the rock core, one is the Martian atmosphere, and one is the reference tube for judging the pollution from the rover.
