Billions of years ago, water on Mars dried up, leaving behind various sulfate minerals, including gypsum. sellam explained, Gypsum has been widely detected on the Martian surface and is known for its exceptional fossilization potential. It forms rapidly, trapping microorganisms before decomposition occurs, and preserves biological structures and chemical biosignatures.
To simulate Martian conditions, the scientists collected gypsum samples from the Sidi boutbal quarry in Algeria. These samples were then analyzed using a mass spectrometer and an optical microscope.The scientists followed specific criteria designed to distinguish between potential microbial fossils and naturally occurring rock formations,ensuring a rigorous and accurate analysis.
The focus on gypsum is due to its unique properties. As water evaporated on Mars, gypsum and other sulfates formed, potentially trapping and preserving any microorganisms present. Gypsum’s rapid formation is crucial, as it can encapsulate microorganisms before decomposition occurs, preserving their biological structures and chemical biosignatures for billions of years.
The scientists are optimistic that this new laser technology, combined with the ongoing exploration efforts of NASA’s rovers, will bring them closer to answering the essential question of whether life once existed on Mars.The ability to analyze the chemical composition of samples in detail, down to the micrometre, offers a powerful tool for detecting even the faintest traces of past life.
The progress of this new laser technology represents a significant advancement in the search for life on Mars.
