3 mysterious craters found on Mars, presumably 4 billion years old: ookezone techno


PLANET Mars actually suffered collisions from asteroids and comets launched 4.6 billion years ago. As a result, the surface of the Red Planet is covered by approximately 43,000 craters.

Astronomers recently saw three mysterious whammy craters made up of three overlapping basins. This is estimated to have been the result of an impact about 4 billion years ago in the region of Noachis Terra, Mars.

This basin is not as large as the other Noachis Terra craters. Some of them can stretch for almost 140 kilometers and the smaller craters are 28 km wide. The overlap that occurs in the crater adds another 45 km to its width.

Researchers are unsure whether the crater was formed by one or more collisions. However, there are allegations that the object that hit him split into three parts before hitting mainland Mars.

This kind of thing isn’t the first time it’s been discovered. In early 2015, astronomers found triple craters similar to Elysium Planitia or near the equator of Mars.

Then, in 2017, the Mars Reconnaissance Orbiter saw a depression extending from three craters that astronomers say came from three flying parts in close formation.

“At three different times, three different impactors could hit the surface of Mars in this position, creating a completely random overlap of the crater,” explained the European Space Agency (ESA). Science notice, Monday (16/11/2020).

Considering how large the asteroid-bombed planet Mars is, it is very likely that it could be the cause.

Similar to other nearby craters, these three overlapping basins show flat edges and shallow floors due to the wear and tear of time.

Some other markings, such as glaciers, can help soften the ground and fill reservoirs as the ice melts.
