'300+ meteor strike every year': Scientists reveal the cause behind Mars' frequent quakes Produced by: Tarun Mishra Credit: NASA/JPL-Caltech/University of Arizona Research Breakthrough An international team, led by ETH Zurich and Imperial College London, has utilized seismic data to estimate the frequency of meteorite impacts on Mars, marking a significant advancement in planetary science. Credit: NASA/JPL-Caltech/University of Arizona Impact Frequency Researchers determined that Mars experiences between 280 to 360 meteorite strikes annually , forming craters larger than 8 meters across—a rate five times higher than previously estimated using orbital imagery alone. Seismic Detection Method Utilizing data from the NASA InSight Mission's seismometer , the team identified seismic signals associated with meteorite impacts, termed as very high frequency (VF) events. These signals differ from typical mars quakes due to their rapid onset and short duration.

Credit: NASA/JPL-Caltech/University of Arizona Scientific Insights Meteorite impacts on Mars are crucial for understanding the planet's geological history, as crater density provides insights into the age and evolution of Martian landscapes. Technological Application The precise detection of meteorite impacts aids in planning future Mars missions, ensuring safety protocols for robotic and potentially human explorations. Planetary Comparison Mars, with its thinner atmosphere and proximity to the asteroid belt, experiences more frequent and larger meteorite impacts compared to Earth, influencing its surface dynamics. Future Research Directions Researchers aim to enhance impact detection capabilities using machine learning algorithms for satellite imagery analysis and further refine seismic data interpretation. Mission Relevance This pioneering research aligns with Mars exploration goals, providing foundational data essential for future missions and expanding our understanding of planetary dynamics beyond Earth.
