The strongest recorded earthquake shook the Red Planet

NASA's Insight probe has just recorded three strong earthquakes on Mars, giving scientists a much clearer picture of the Red Planet's inner space. Earthquakes break records set by Insight, including most powerful earthquake quake. And has recorded a magnitude of 4.1. Another earthquake occurred on September 18 (September 27) that lasted about 90 minutes. The previous record set by Insight for Martian earthquakes was in 2019, when a 3.7 magnitude earthquake was almost 5 times less powerful than recent earthquakes.

Insight , Geological and heat transfer) landed near the equator of Mars in November 2018 and is tasked with exploring the inner space of the planet in a different way. The main scientific instruments of this surface include a thermal probe and a very sensitive set of seismometers. The mission team also uses Insight communication tools to pinpoint its location on Mars. This information shows how much the planet moves around its axis, thus revealing its internal structure. . The tool was never able to reach great depths on Mars because the Martian soil was an unexpectedly unsuitable location for drilling. But Martian seismometers have been very successful in recording hundreds of earthquakes to date. The first earthquake recorded by the Insight Surface

Analysis of these tremors allows the Insight team to map the interior of Mars in detail. For example, surface observations show that the Red Planet has a very large nucleus and a relatively thin crust.

Powerful recent earthquakes on the planet could make this image clearer Help the internal structure of Mars. The Insight team is still studying the September 18 earthquake, but the study of previous earthquakes is somewhat complete. For example, the data show that the 4.2-magnitude earthquake struck about 8,500 km from Insight. Many earthquakes are strong and far away. A place called the "Cerberus Fossae" about 1,600 km from Insight, where volcanic lava flowed until millions of years ago.

"It is very likely Valles Marineris," he said. A collection of very long valleys that stretch along the equator of Mars. The approximate center of the complex is about 9,700 km from Insight. The quake was fast and high frequency, while the 4.2 magnitude quake had a lower frequency. "Even after two years of recording various data, these two earthquakes seem to have given us new information and unique features," said Bruce Banerdt, Insight lead researcher at NASA's Jet Propulsion Laboratory on the Earthquake.

Insight and its controllers have worked hard to record and report these new earthquakes. A lot of dust has accumulated on the surface since landing, which greatly reduces the output power. This problem has recently been exacerbated by the movement of Mars in its orbit away from the Sun. The Red Planet reached the farthest point from Earth on July 12.

So the mission team temporarily turned off several energy-saving devices and enabled the spacecraft's internal heaters, and cleared some of the dust on the solar panels. . This was done using a surface-mounted robotic arm to remove sand from the solar panels.

According to team members, these efforts kept Insight at a relatively stable level of performance at peak orbits. "If we had not acted quickly earlier this year, we might have lost some important scientific tools," Banrandt said.

The Insight team is currently considering whether to do more dust removal Or not? However, this activity must be done after the solar collision of Mars. Because at this time the sun is between Earth and Mars and disrupts communication with the probe, so there may be a problem with the commands.

It will be suspended for two weeks and will end on October 14, according to NASA.
