Mars exploration: NASA’s Curiosity searches for new clues about ancient water | Top Vip News


The presence of water on Mars, Earth’s neighbor, is not a foreign concept. Astronomers have been talking about the presence of water on the Red Planet for decades without evidence. However, a recent study by an international team has suggested that the solar system’s fourth planet from the Sun may have retained more water for a longer period than previously thought.

As the curiosity rover The National Aeronautics and Space Administration (NASA) has begun exploring a new region of Mars, namely the Gediz Vallis Canal, which appears to have been carved by an ancient river, and could reveal more about when it once disappeared. for all the liquid water of the Red Planet. surface.

The rover team is focusing on the Gediz Vallis channel and looking for evidence that confirms how the channel was carved into the underlying bedrock. The sides of the formation are steep enough that the team doesn’t believe the channel was created by wind.

The rover’s journey through this region aims to discover the formation process of the Gediz Vallis channel, whether debris flows (rapid, wet landslides) or a river carrying rocks and sediments could have formed the bedrock. . Scientists are also eager to know whether the debris was transported by water or dry avalanches.

Since 2014, Curiosity has been ascending the foothills of acute mount on the floor of Gale Crater to explore the assessment of climate change on Mars. Studying the layers formed over millions of years at the bottom of Mount Sharp may provide scientists with a clue about how the presence of both water and the chemical ingredients necessary for life changed over time. These layers present a chronological record of Mars’ environmental changes, crucial to understanding its potential for past life.

“If the channel or the rubble pile was formed with liquid water, that’s really interesting. It would mean that quite late in the history of Mount Sharp, after a long dry period, the water returned, and to a large extent,” said Curiosity project scientist Ashwin Vasavada of NASA’s Jet Propulsion Laboratory in southern Washington. California.

Last year, Curiosity made a challenging ascent to study the ridge, which covers the slopes of Mount Sharp and appears to grow from the end of the channel, suggesting the two are part of a geological system.

This Curiosity exploration contributes to a growing body of evidence suggesting that Mars experienced water in phases, with periods of aridity interspersed with significant watery intervals. Discoveries such as mud cracks, remains of shallow lakes and evidence of the complexity of Mars’ hydrological past. Massive debris flows underscore the complexity of Mars’ hydrological past.
