NASA’s InSight lander discovered a mysterious rumble, called an “earthquake,” which provided further clues to the volcanic activity on the surface of the “red planet.”
Tremor It originated in an area called Cerberus Fossae-NASA scientists have conducted important seismic activities in the area in the past, and even landslides have occurred.
they It is believed that the tremor may be caused by the sudden release of energy below the planet’s surface, bSince Mars does not have tectonic plates like the Earth, the exact cause and origin of the rumble is still unknown.
The earthquake is collected by the InSight seismograph, which is a vehicle-mounted device specially used to capture earthquakes.
InSight uses a robotic arm to partially bury the seismograph to protect it from strong seasonal winds and obtain more accurate readings.
NASA’s InSight has discovered two major earthquakes in the Cerberus Fossae area on Mars, further confirming the idea that the location is active in earthquakes.

Three major missions to Mars in 2021: the United States, the United Arab Emirates and China on the red asteroid or on the red asteroid
So far, 2021 has been the “Year of Mars”, and three spacecraft from the Earth have reached the Red Planet.
The first visitor from the earth was also the first visitor to the Arab world-the “Hope” probe in the United Arab Emirates.
This spacecraft will monitor the weather on Mars for a whole year.
The second spacecraft is from China-Tiantian-1 will operate on Mars until May, when it will deploy a rover.
If successful, this will make China the second country to roam on Mars after the United States.
NASA’s perseverance is the last of the three stars to reach the orbit of Mars, but also the first star to land on the red planet.
Cerberus Fossae is the area where the earthquake was detected-a steep area cut into the volcanic plain, and active landslides were photographed in 2019.
Interestingly, after two previous earthquakes in the same area, the earthquake almost happened in one Martian year or two Earth years.
NASA said in its statement announcing the earthquake that InSight has recorded more than 500 earthquakes so far, but due to the clear signal, these four are the best seismic records for detecting the interior of the planet.
Taichi Kawamura of the Institute of Geophysics in Paris, France, provided support for the mission of the National Aeronautics and Space Administration (NASA).
He said: “During the mission, we have seen two different types of earthquakes: one is more like the “moon” and the other is more like the “earth”.
Kawamura said that seismic waves travel more directly through the earth, while seismic waves are very scattered.
The earthquake is somewhere in between.
Interestingly, these four major earthquakes came from Hellhounds, and they are all earth-like.
InSight launched from Vandenberg Air Force Base in California in May 2018 and landed on Mars in November of that year. Its mission was to conduct a comprehensive inspection of the planet for the first time since its formation 4.5 billion years ago.
It works with multiple missions orbiting Mars and wandering around the Earth’s surface: including the “Curiosity” rover.
InSight can adapt to the extremely harsh conditions on the earth, thereby obtaining more accurate data.
It usually faces extreme temperature fluctuations-from minus 148 degrees Fahrenheit to 32 degrees Fahrenheit at night-and severe seasonal winds.
It hopes that Martian summer will bring calmer weather and make it easier to spot other earthquakes.
In order to record more accurate data, the InSight lander has begun using shovel on its robotic arm to place soil on the cable connecting the seismograph (called the Seismic Experiment for Internal Structure (SEIS)) and the spacecraft.
“This keeps the soil as close as possible to the shielding layer without disturbing the sealing of the shielding layer to the ground.”
Scientists hope that isolating it from the wind will make it easier to detect earthquakes.
The new earthquake is smaller than the 3.6 and 3.5 earthquakes of the two previous earthquakes detected in the same area.
InSight has recorded more than 500 earthquakes so far, but due to the clear signal, these are the four best seismic records for exploring the interior of the planet.
Since arriving in November 2018, the InSight lander has completed several missions orbiting Mars and wandering around the surface of the Earth: including the Curiosity Rover
In 2019, the National Aeronautics and Space Administration (Nasa) found evidence of an active landslide on Cerberus Fossae, a trough cut into a volcanic plain on Mars
The “Curiosity” rover also took a pair of panoramic photos using its Mastcam camera
Earlier this week, NASAThe Curiosity Mars rover took a selfie of himself with the 20-foot-tall “Monmogu” rock formation.
The selfie shows a rock formation named “Mont Mercou” next to the rover, the nickname taken from a mountain in France.
Although the picture itself is impressive, it was actually taken to celebrate Curiosity’s 30th sample to date.
On March 4, Curiosity also used its Mastcam to take a pair of panoramic photos.
NASA explained: “By taking a panorama at a position about 130 feet (40 meters) from the outcrop, then rolling to the side and taking another shot from the same distance, the rover produced a view similar to that seen in a 3D viewfinder To the three-dimensional effect.
“Studying outcrops from multiple angles helps scientists better understand the 3D geometry of the sedimentary layers of Mount Merkur.”
Curiosity is the largest and most capable rover ever sent to Mars and is part of NASA’s Mars Science Laboratory mission.
It was launched from Earth on November 26, 2011, and landed on Mars on August 5, 2012, a year later.
The main task of the Wanderers is to uncover their mystery about whether Mars has the right conditions for sustaining life.
NASA added: “The scientific tools of Curiosity discovered chemical and mineral evidence of the habitable environment on Mars early in the mission.
“From the time when microbes could have lived on Mars, it has continued to explore the rock record.”
