Mars study has found evidence of severe flooding on Mars

The new image also reveals where the rover can collect new monsters.

Perseverance on Mars still haunts the canyon of Xero; Scientists believe that part of Mars was a crater lake that filled with water billions of years ago. The hole had long since dried, so the plow now crossed the cracked red bottom. With camera in hand. New films now reveal a new chapter in Jessero Greater’s fascinating history.

Kodiak
Perseverance took photos of the many rocks and boulders in the ancient delta region of Mars, including a boulder called “Kodiak”. In ancient times, Kodiak was on the southern edge of the delta. Before the advent of persistence, The Rock was only photographed from space. But thanks to Mars, scientists are now manipulating closer-up photos.

The new image reveals interesting details about the rock, namely the sequence of adjacent rock layers on the east side. It provides new information about when geological deposits occurred.

This confirms scientists’ suspicions that once rich water flowed through the Jessero Gorge. “Mars has never had such a well-preserved layer,” said researcher Nicholas Mangold. “This is a very important observation that once showed that there was once a lake and a river delta in the Jesero Valley.”

While this is certainly an impressive result, the researchers were surprised by the story the cliff images tell in the northeast delta. At the base of the steep slope, the researchers found layers of Kodiak-like rock. But above, the group saw large boulders and large boulders. “We saw several layers of steep cliffs with rocks up to 1.5 meters high and we knew there was no business there,” explains Mangold.

According to the panel, there is only one explanation for this. That was billions of years ago, when the fan-shaped Jessero Delta experienced a major flood. These stones and debris were carried from a height and then placed on steep slopes. Mangold and his team estimated that jets of water were needed to move the rock – about ten kilometers – at an astonishing speed of 6 to 30 kilometers per hour.

The new film also reveals where perseverance can gather new monsters. “In our search for organic compounds and biological signatures, we can now place our best bets on the best granular materials found at the bottom of the delta,” said researcher Sanjeev Gupta. In addition, the rocks above allow us to model ancient crystalline rock specimens. So, both are on the agenda. ”

Slowly but surely, scientists began to better understand Slideo Greater. Early in the history of the former lake, the water level was thought to be high enough to reach the eastern edge of the gorge, while earlier images revealed the remains of a flowing river canal. This study provides additional evidence for this and sheds light on the size of the lake undergoing significant changes. In this way, over time the water level rises and falls, eventually disappearing completely. While it is not known whether these fluctuations in water level were caused by floods or gradual changes in the environment, we now know that they occurred in the history of the Greater Jesuits, at least 100 meters below sea level. His level reached so far.

It won’t be long before scientists combine several pieces of the puzzle together. Delta will be the starting point for the next two diligent missions. “A good understanding of the Jessero Delta is important for understanding watershed changes in the region,” notes Gupta. “It can also provide valuable insight into why the entire planet is becoming dry.”
