🔎 NASA’s InSight Lander Discovers New Secrets About the Red Planet
Since its arrival on Mars in 2018, NASA’s InSight lander has been recording seismic activity, providing unprecedented data on the planet’s internal structure. Scientists have now analyzed this data and uncovered crucial information about Mars’ core, mantle, and crust, bringing us one step closer to understanding the planet’s formation and evolution.
🏜️ A Dynamic and Active Planet
Before the InSight mission, much of what we knew about Mars’ structure came from meteorite analysis and theoretical models. However, the lander’s seismometers have detected hundreds of "marsquakes," allowing scientists to measure how seismic waves travel through the planet’s different layers.
The latest findings reveal that Mars has a smaller, less dense liquid metal core than previously thought. Researchers have also discovered that its mantle extends deeper than expected and that its crust is thicker than assumed. These insights suggest that Mars' geological evolution has been vastly different from Earth’s.
🛰️ What Does This Discovery Mean?
Understanding Mars’ internal structure not only helps reconstruct its history but also provides clues about the evolution of other rocky planets, including Earth. Moreover, this knowledge is crucial for future crewed missions, as knowing the planet’s geological stability is essential for human exploration.
NASA’s team continues analyzing seismic data, hoping to uncover more details about Mars’ composition. With each new discovery, we move closer to answering one of humanity’s greatest questions: Was Mars ever habitable?
