Jakarta, CNN Indonesia –
The roar came from the equatorial region of Mars called Cerberus Fossae. The mysterious roar is called the same as the earthquake phenomenon on Earth. This phenomenon occurred on March 7 and March 18. The series of faults in Cerberus Fossae is one of the most geologically active places on the Red Planet today.
The researchers suspect, the phenomenon occurs because of the sudden release of energy from inside Mars. The phenomenon, called Marsquakes, is thought to have occurred before at Cerberus Fossae.
The Cerberus Fossae region is filled with a series of large basins that are almost connected to each other. The series was created when there was volcanic activity on the planet.
Quoted Sciencealert, the Cerberus Fossae region is one of the centers of seismic activity and is interesting to study because of its geological instability.
According to NASA experts, Marsquakes or earthquakes on Mars do not have the same tectonic mechanism as earthquakes on Earth. But strangely the incident was recorded exactly once a year on Mars, or every two years on Earth in the northern part of Mars.
Sky News preach, the surface of Mars is almost like the Moon which is much calmer than Earth. However, the surface of Mars can experience vibrations due to the process of contraction which causes pressure on the surface of Mars.
NASA scientists predict that this summer InSight will have the opportunity to listen to earthquakes because the winds on Mars are calmer.
NASA uses an InSight Seismometer called the Seismic Experiment for Interior Structure (SEIS) to detect rumbling sounds. This system will later record the movement of the Martian surface.
Because Mars is moving away from the Sun, currently InSight’s performance is decreasing, because it doesn’t get power from sunlight.
InSight is predicted to gain energy after Mars’ position is close to the Sun again in July.
Until now the team will turn off the InSight instruments one by one so they can hibernate to save power, and wake up periodically to check their own condition and send messages to Earth.
