Deep Seismic Waves Reveal Secrets of Mars’ Interior
A recent breakthrough in our understanding of Mars’ interior stems from the analysis of seismic data recorded by the Insight lander. In two separate studies published in Geophysical Research Letters on February 3, 2024, scientists unveiled how seismic waves from meteoroid impacts travel deeper than previously thought, offering valuable insights into the planet’s structure.
Unveiling the ‘Seismic Highway’
The Insight lander, equipped wiht a highly sensitive seismometer, recorded over 1,300 Marsquakes during its four-year mission, which concluded in 2022. These quakes originated both from deep within the planet and from surface impacts. By analyzing the passage of seismic waves through mars’ crust, mantle, and core, researchers gained a glimpse into the planet’s internal structure.
Prior to these discoveries, scientists believed that most seismic energy from impacts remained trapped within the planet’s crust. Though, data from a specific impact event in Cerberus Fossae, a region known for its seismic activity, revealed a surprising phenomenon. the impact, which created a 21.5-meter diameter crater, generated seismic waves that propagated through the mantle in a more direct pathway, bypassing the crust.
“We thought the energy recorded from most seismic events remained captured at the passage of Mars’ bark,” says Constantinos Charalambous of Imperial college London, a member of the Insight mission team. “These discoveries show a deeper and faster way – say the seismic highway – through the cloak, allowing shocks to achieve more distant areas of the planet.”
Rethinking Mars’ Interior
This unexpected finding challenges existing models of Mars’ interior structure and composition.The scientists now need to reconsider how the crust behaves and how seismic energy travels through the planet’s mantle. This deeper understanding of Mars’ interior provides valuable clues about the formation and evolution of not just Mars, but rocky planets in general, including Earth and the Moon.
Moving Forward
these groundbreaking discoveries highlight the power of collaborative science and the amazing insights gained from robotic exploration. as future missions to Mars delve deeper into the planet’s mysteries, the data from Insight will continue to serve as a cornerstone for understanding our celestial neighbor.
A New Martian Crater Hints at a Seismic Mystery
A recent finding on Mars is reshaping our understanding of the planet’s seismic activity. Scientists have discovered a new impact crater in the Cerberus fossae region,a seismically active area,and linked it to seismic shocks recorded by NASA’s InSight lander.
This groundbreaking link was made possible through the use of advanced machine learning algorithms developed at NASA’s jet Propulsion Laboratory (JPL). These algorithms combed through tens of thousands of images from the Mars Reconnaissance Orbiter’s Context Camera,searching for signs of fresh impact craters.
“If we did it manually, it would be years of work,” says Valentin Bickel of the University of Bern, who led the research. “With this tool, we got down to a few days from tens of thousands of images. It’s not as good as a human,but it’s super fast.”
The team identified 123 fresh craters that could perhaps match seismic data recorded by InSight, narrowing the list down to 49 candidates after a thorough analysis. Through further analysis, they pinpointed a specific crater located in Cerberus fossae that aligned perfectly with a recorded seismic event.
“We thought Cerberus fossae produced many high-frequency seismic signals associated with internal Martian activity, but this suggests that part of the activity does not come from this area and that it might very well be caused by impacts,” said Charalambous, a seismologist involved in the study.This discovery highlights the power of AI in planetary science, allowing researchers to process vast amounts of data and uncover hidden patterns.
The discovery not only sheds light on the seismic activity on Mars but also demonstrates the impactful synergy between various space missions and AI technology. By integrating data from InSight, MRO, and advanced algorithms, scientists are gaining unprecedented insights into the Red Planet’s dynamic nature.

Recent advancements in artificial intelligence (AI) are revolutionizing planetary exploration, enabling scientists to delve deeper into the mysteries of celestial bodies like Mars. researchers are increasingly turning to AI algorithms to sift through vast amounts of data collected by spacecraft, uncovering hidden patterns and insights that would or else remain elusive.
“Now we have so many photos of the moon and Mars that there is a problem with thier processing data analysis,” said Dr.Bickel, highlighting the challenge of managing the exponential growth of planetary imagery. “We have finally reached the era of large data in a planetary survey.”
one groundbreaking request of AI in planetary science involves analyzing seismic data. NASA’s Insight lander, equipped with a sensitive seismometer, has recorded thousands of marsquakes, providing invaluable information about the planet’s internal structure. AI algorithms are being used to interpret these seismic waves, revealing the depth and composition of Mars’ core, mantle, and crust.
Furthermore, AI is proving instrumental in identifying geological features on Mars, such as craters, landslides, and slope stripes. These distinctive markings,often referred to as repeating slope lines,provide clues about the planet’s geological history,erosion patterns,and potential for past or present life.
The ability of AI to analyze vast datasets opens up exciting possibilities for future planetary missions. As we continue to explore our solar system, AI will play an increasingly vital role in uncovering the secrets hidden beneath the surface of celestial bodies, providing deeper insights into the formation and evolution of planets.
For researchers, embracing AI tools means embracing efficiency and accuracy. It allows them to sift through mountains of data, identify patterns, and formulate hypotheses faster than ever before. This accelerated pace of discovery drives progress in planetary science, pushing the boundaries of our understanding of the cosmos.
Embracing AI in planetary exploration is not just about technological advancement; it’s about expanding our scientific horizons. The insights gleaned from AI-powered analysis will continue to shape our understanding of Mars, Earth, and the universe beyond.
