Jakarta –
For the first time, scientists have mapped the internal structure of a planet other than Earth. They also dismantle the nature of the core Mars, through seismic waves.
These are elastic waves generated by the earthquake and propagate to the surface. Data was also collected by NASA Insight (Interior Exploration using Seismic investigations, Geodesy and Heat Transport), where more information was obtained than before.
The period starts from the first half of the time of landing on Mars. For now, its mission has been extended to 2022, where InSight first docked in 2018 and started recording earthquakes in February 2019, reported detikINET from Vice, Monday (26/7/2021).
NASA also uploaded a recording of the earthquake that occurred, to the sound distribution platform, SoundCloud. If you are curious, you can listen to it directly via the following link: Quake Question 173.
A seismologist, Simon Stahler, said that the earthquake that occurred was indeed very small. However, it is estimated to occur two to 10 times in one day.
One study also revealed that the Martian core has a depth of up to 969 miles. Meanwhile, its density is quite low compared to Earth, estimated to be around 5.7 to 6.3 cubic centimeters, where the iron and nickel alloy has a low sulfur content.
The researchers also found that Mars has a relatively thin Mantle, where it lacks a layer of bridgmanite like Earth. This can cause the planet’s core to cool faster.
The data also revealed that Mars initially had a very strong magnetic field, like the third planet from the Sun.
Another study, led by the head of the University of Cologne seismological observatory, Dr Brigitte Knapmeyer-Endrun, concluded that beneath the InSight landing site, the crust was 20 km or 39 km thick.
Although this is a breakthrough, in the understanding of planetary structure. The InSight landers, however, still have many limitations and they are the only seismometers on Mars.
Thus, its ability to measure seismic throughout planet very limited. Plus, there are several factors that interfere with the research, such as strong winds and cold temperatures.
