The New Seismic Discovery Beneath the Surface of Mars
Nautilus · 2026-06-26
New analysis of data from NASA’s InSight seismometer, which operated on Mars from 2018 until 2022, reveals a surprisingly complex Martian crust. Scientists at the University of Oxford have determined that the composition of these subsurface layers indicates a rock recycling process similar to Earth's, despite Mars's "stagnant lid" tectonics. This process involved molten rock pooling underground, suggesting a more dynamic interior than previously assumed. These findings, published on June 26, 2026, carry significant implications for the potential habitability of other rocky bodies in the solar system. According to study co-author Jon Wade, if Mars can develop such a complex crust without plate tectonics, then conditions suitable for habitability might be present on a wider range of planets, including those that were previously overlooked due to their size or perceived lack of tectonic activity.
