# Abundant Organic Molecules Found by Perseverance Rover on Mars
Written on
Chapter 1: Introduction to Mars Discoveries
NASA's Perseverance rover has made remarkable discoveries of organic molecules on virtually every target it examines, suggesting that Mars may have once been rich in life. Recent findings from the rover reinforce theories that life could have thrived on the planet billions of years ago. A press conference held last Thursday highlighted these groundbreaking results.
Perseverance has identified various organic compounds in the Jezero Crater, an ancient lakebed where it landed last year. According to NASA, these organic compounds were found in abundance across all scanned locations, indicating their widespread presence on the planet.
Section 1.1: Enhanced Detection with SHERLOC
While previous discoveries of organic molecules were made by NASA's Curiosity rover, Perseverance's findings are more detailed and precise. Equipped with the advanced Scanning Habitable Environments with Raman & Luminescence for Organics & Chemicals (SHERLOC) instrument, the rover can accurately identify and label different minerals and organic compounds.
SHERLOC detected aromatic compounds—ring-structured organic molecules—within a core sample taken from a rock at Wildcat Ridge in Jezero Crater. This core showcases a diverse sedimentary history that includes salts and sulfates, remnants from a time when water existed on Mars three billion years ago. It's astonishing, isn't it?
Perseverance extracts sample cores from various terrains throughout Jezero Crater, which features a river delta system that may have previously supported life. These samples are destined for future return to Earth by another rover on a different mission, where they can be analyzed in laboratories to identify specific microbial life.
Subsection 1.1.1: Insights from Sample Analysis
So far, twelve samples have been collected and analyzed, offering a glimpse into a nutrient-rich Martian past. Sunanda Sharma, a SHERLOC scientist at NASA's Jet Propulsion Laboratory, shared insights during the briefing, stating, "It’s clear that we are uncovering a bigger story unfolding in Jezero Crater." She emphasized, "We’ve detected potential signals from organic matter in every target we’ve observed, aligning with findings from Earth studies of Martian meteorites."
Section 1.2: The Significance of Resilient Organic Molecules
A particularly intriguing aspect is the discovery of these molecules in extreme environments, suggesting that Mars may be home to resilient, life-sustaining materials. While it does not confirm that life ever existed on the planet, it brings us closer to understanding whether we are alone in the universe.
Sharma expressed her excitement, saying, "I personally find these results incredibly moving because it feels like we are in the right place with the right tools at a crucial moment." While we await the return of these cores to Earth, the news is promising. Perhaps our long-held imaginations of Martians are not so far-fetched after all.
