Scientists have considered Mars to be a dead planet. However, measurements of earthquakes on Mars indicate that there may still be movement of molten rocks beneath the planet’s solid crust.
The magnetic field of the earth is created by the movement of conductive materials in the planet’s core. The heat emitted from the solid inner core layer heats the base of the liquid outer core layer, which creates a circular flow pattern that creates the magnetic field.
Mars has no magnetic field and no internal circulation currents, indicating that its core and mantle are relatively cold and quiet.
NASA’s InSight lander measured 465 earthquakes on Mars. Many of them were caused by the two small moons of Mars tidally pulling on the surface and the sun heating it.
Researchers measured hundreds of earthquakes on Mars using the Insight lander’s seismometer. They found 47 previously undetected earthquakes, which occurred over a period of 350 Mars days, i.e., 359 Earth days.
The Researchers think Mars’ tremors are caused by a molten rock moving in the upper mantle. On the other hand, the loss of the magnetic field may be due to another factor.
Earthquakes on Mars
Mars may be more active than we thought, with molten rocks still moving beneath its solid surface.
Mars has a relatively cool and quiet core and mantle that does not lose significant heat into space and do not create any internal circulation currents.
Scientists have found that underneath the surface of Mars, a lot of activity is taking place. The tremors are being caused by the stretching and contracting of the surface and the warming of the surface by the Sun.
Measurements of earthquakes on Mars indicate that it is not a geologically dead planet, and that molten rocks are still moving beneath its solid crust.
The slow cooling of the planets creates a magnetic field, and the flow of heat from the solid inner core layer to the liquid outer core layer creates earthquakes.
Scientists have measured 465 earthquakes on Mars since the seismic sensors began to operate, and the vast majority of them were caused by the stretching and contraction processes of the surface.
The mantle around the core
The movement of conductive materials in the earth’s core and the mantle around the core creates the earth’s magnetic field. The movement of conductive materials in the core also creates the earth’s tectonic plates and earthquakes.
Mars has a relatively cold and quiet core and mantle, which do not lose significant heat to space and do not create internal circulation currents. However, researchers believe that the movement of molten rock in the upper part of the mantle is responsible for the tremors discovered on Mars.
NASA’s InSight Records the largest quake ever observed on another planet
InSight has detected 1,313 quakes on Mars since November 2018, including the largest quake ever observed on another planet.
InSight was sent to Mars with a highly sensitive seismometer to study the planet’s deep interior. The seismometer detected a magnitude 5 quake, and scientists are now analyzing the data to learn more about the structure of Mars.
The large earthquake comes as InSight faces new challenges with its solar panels. The mission may enter safe mode again as available power slowly decreases.
