In new research, researchers on the planetary Used Global and high -resolution orbital images to discover fresh 21.5 m (71 feet) impact craters that appeared at the same time as one of the Marsquakes detected by NASA's Insight Lander. This means that the seismometer detected a meteor strike, not a geological activity in the planet. In the related research, they scan Through a large number of orbital image data, the 123 shock crater was formed from December 2018 to December 2022.

NASA's Insight Lander set the first seismometer on Mars and detected more than 1,300 Marsquakes. This is generated by the shaking deep of the planet (caused by a rock broken under heat and pressure) and a cosmic rock that collides with the surface.
Scientists not only glimpse the inside of Mars, as science glimpses how the waves of the earthquake change from these earthquakes when passing through the earth's crust, mantle, and core. I understand how all the rocky world, including the month, is formed.
In the past, researchers shot new shock craters images and found seismic data that matched the date and location of the crater layer.
However, two new studies indicate that the shaking and the new effects detected in Cerberus Fossae, which are particularly prone to earthquakes of 1,640 km (1,019 miles) of 1,640 km (1,019 miles) from insights, are the first correlation. Masu.
The diameter of the shock crater is 21.5 m, which is far from the insight than the scientist expected, based on earthquake energy.
Mars crusts have unique characteristics that are considered to suppress seismic waves generated by impact. The new analysis of Cerberusfossae concluded that the generated waves take more direct routes than the planet mantle.
The Insight team needs to re -evaluate the internal configuration and structural models of Mars, and explain how to make the impact -generated earthquake signals so deep.
“We thought that the energy detected from most of the earthquake events was moving through the crust of Mars,” said Dr. Constantinoscharamanbus, a researcher of Imperial College London. Masu.
“This discovery shows a deeper and faster path -it is called an earthquake highway, so that the earthquake can reach the farthest of the earth through the mantle.”
Researchers also wanted to find a crater within the location of about 3,000 km (1,864 miles) and find something that was formed while the Lander seismometer was recorded.
By comparing images before and after the context camera mounted on NASA's Mars Reconnasance Orbiter (MRO), I found 123 fresh craters to interact with INSIGHT data. Of these, 49 was a potential agreement with the earthquake detected by the Lander seismometer.
“I thought that CERBERUS FOSSAE has generated many high -frequency earthquake signals related to internal generated earthquakes, which suggests that some activities are not born there, and actually from the impact. Dr. Charalambous said.
The results of the survey also emphasize how researchers use AI to improve planetary science by using all data collected by NASA and ESA missions.
“Now, we have a lot of images from the moon and Mars, so the struggle is to process and analyze data,” said Dr. Dr., a member of the Bern University researcher. I mentioned it.
“We have finally arrived in the big data era of planetary science.”
