NASA InSight detects meteorite hitting Mars
on December 24, 2021, NASA's "Insight" lander detected a "Marsquake" in the Amazonis Planitia region of Mars At the time, researchers thought it was a "Marsquake", but new research has found that it was actually caused by a meteorite impact. Comparing the before and after photos, the researchers found that a 492-foot (about 150 meters) long crater appeared on the surface of Mars.
According to estimates, the length of the meteoroids is between 16-39 feet (about 4.9-11.9 meters), and if they were Earth, they would be burned by the atmosphere, but the thin atmosphere of Mars allows them to "survive". The consequences of the impact were severe. A 70-foot-deep crater appeared on the surface, and debris was thrown up to 23 miles (37 kilometers) from the crater. We can also see surface ice, which appears very close to the Martian equator.
So far, InSight has detected about 1,300 marsquakes, of which experts believe 20 may be magmatic activity. Analyzing the spectral signature of Marsquakes, the crust in the Cerberus Fossae region of Mars may be relatively soft, which, combined with the dark dust analysis, may indicate that Mars has been volcanic for the past 50,000 years. Whether there are still active volcanoes on Mars, scientists debate whether it is in the right place, and there is no unanimous conclusion. The softer crust means that there is still magma inside Mars.
