The US team of the Insight Mars rover has published a symconference showing new discoveries that have been made more than a year after Insight landed on Mars. Mars is a planet full of “Mars earthquakes”, dust storms and magical electromagnetic pulses, according to the probe. The paper is published in the British journal Nature and the journal Nature Geoscience.
According to the paper, Insight’s preliminary findings suggest that there are “Mars earthquakes” from distant and mysterious sources on Mars, with strong magnetic signals on local surfaces, as well as special atmospheric motion.
According to reports, so far the mission team has been through the seismometer “listening” to the distance from “insight” hundreds to thousands of kilometers away from more than 450 vibration signals, the vast majority of which may be “Mars earthquake.” “Mars earthquakes” are more frequent and gentler than scientists had expected. Because the spread of Martian seismic waves is influenced by the medium, scientists can study the interior of Mars.
The first Mars magnetometer on board insight found that the magnetic signal in the Homestead Valley, the crater where Insight landed, was 10 times stronger than previously predicted by the Mars Orbiter’s research data on the region.
Catherine Johnson, a professor at the University of British Columbia in Canada and one of the authors of the paper, said that because most of the surface rocks on the Insight lander were too young to be magnetized by the Martian primary magnetic field, the region’s strong magnetic field must have originated from ancient rocks deep underground. The researchers will study the intensity of the magnetization layer deep in Mars, based on data from the dymeter and information from seismology and geology.
In addition, Insight’s weather sensors have detected thousands of cyclones, and have obtained far more data than any previous Mars rover. Based on this, the researchers believe that the dust storm slot at insight site is more frequent than the previous Landing Site of other Mars rovers, but so far Insight’s camera has not been able to capture the dust storm.
The mission team said Insight’s mission will be a Mars year (about 687 days), and that Insight will continue to explore the Martian “core” and that its “rotation and internal structure experimenter” will probe whether Mars’ “inner most” is liquid or solid by recording the Martian oscillation.
Insight successfully landed on The Ehrlich Plain on November 26, 2018, carrying out its first human mission to explore Mars’ “deep heart”, carrying scientific instruments including seismometers, temperature measurement devices, “rotational and internal structural experiments”, meteorological sensors and magnetometers.
