Mars’ Hidden Secrets Revealed: Scientists Unveil Groundbreaking Gravity Map

As scientists from around the world gathered at the Europlanet Science Congress 2024, a groundbreaking study revealed a comprehensive gravity map of Mars, painting a picture of a planet with ongoing internal processes. Led by Bart Root from Delft University of Technology, the research team combined data from multiple missions, including NASA’s InSIGHT and measurements of tiny orbital deviations from Mars-orbiting satellites.

Key Findings:

• A previously unknown mantle plume is rising beneath the Tharsis region, a region known for its massive shield volcanoes, including Olympus Mons, the largest volcano in the solar system.
• This finding challenges the established geological concept of flexural isostasy, which describes how a planet’s rigid outer layer responds to loading.
• In addition to the Tharsis region, the researchers identified mysterious dense structures beneath Mars’ northern polar plains, buried under thick, smooth sediment layers.
• These anomalies are approximately 300-400 kg/m³ denser than their surroundings and show no corresponding surface features.

The study, detailed in the forthcoming paper "The global gravity field of Mars reveals an active interior" in JGR: Planets, provides a significant advancement in our understanding of Mars’ internal structure and evolution. By challenging established geological concepts and revealing previously unknown features, it opens new avenues for research into the Red Planet’s past and potential future activity.

Mars’ Active Interior: A New Frontier for Research

The possibility of future volcanic activity on Mars cannot be ruled out, suggesting that the planet may still be evolving. The researchers propose the Martian Quantum Gravity (MaQuls) mission, which would employ technology similar to that used in the GRAIL and GRACE missions for mapping lunar and Earth gravity, respectively. MaQuls would feature two satellites connected by an optical link, allowing for precise gravity measurements.

As scientists continue to analyze these findings and push for missions like MaQuls, we may soon gain even deeper insights into the mysteries that lie beneath the Martian surface—perhaps revealing a planet that is still very much alive beneath its dusty red exterior.

Conclusion: The Future of Martian Research

The new gravity map represents a significant advancement in our understanding of Mars’ internal structure and evolution. As researchers continue to explore the Red Planet, we may uncover even more secrets about Mars’ past and potential future activity. With the Martian Quantum Gravity mission on the horizon, the possibilities for discovery are endless.
