Mars is known for its barren desert landscape and dry climate. But two recent studies in the journals <a href="https://www.nature.com/articles/s41586-025-09361-9"target="_blank" >Nature</a> and <a href="https://www.science.org/doi/10.1126/science.adk4292"target="_blank" >Science</a> go beneath the surface, exploring the interior of the red planet using seismic data from NASA’s <a href="https://science.nasa.gov/mission/insight/"target="_blank" >InSight mission.</a> And now, this data is also giving scientists a glimpse into the planet’s history – to see how Mars evolved over billions of years and how its inner structure compares to that of Earth. Interested in more science news?
