The US space agency NASA has claimed to detect several marsquakes on Mars. The revelation was made by the agency’s InSight lander. NASA said the findings show the planet trembles more often than expected earlier. The trembles are more mildly in nature and appear deep beneath the surface. According to the data transmitted by InSight, it detected more than 450 seismic signals. The majority of the seismic signals are possibly quakes. The seismic events were recorded by the lander’s seismometer. The largest tremble was about magnitude 4.0 in size. The first result of the InSight mission was published in the Nature Geoscience and Nature Communications journal.

InSight principal investigators said the findings are interesting parts of the probe as they study the Red Planet’s inner structure. The mission landed in Elysium Planitia on Mars in November 2018. It is equipped with the latest tools that are a seismometer for detecting quakes. It aims to study the composition of the planet’s inner structure. It has sensors for measuring Martian wind and air pressure. Besides, it has a magnetometer to study its magnetic field. It is also designed to take the planet’s temperature. NASA said seismic waves are affected by the materials they move through. It added that the data will help scientists to understand how Mars and other rocky planets first formed.

The Red Planet doesn’t have tectonic plates like Earth. But it has volcanically active regions that cause rumbles. Scientists believe Mars had magnetic field billions of years ago. However, the magnetic field disappeared and is no longer present on the planet. NASA said before the magnetic field disappeared, it left magnetizing ancient rocks. The rocks are between 200 feet to several kilometers beneath the Martian surface. Mars is just next to Earth and the fourth planet in the solar system. Scientists claim that the results of past missions showed signs of life on the planet. NASA is now working to send a new rover before its ultimate goal to send humans by 2030.
