The Gediz Vallis Canal, where they were found, is a key region in understanding Mars’ water history, as it is an ancient river bed. However, the discovery of pure sulfur here surprised scientists, as it was not consistent with the geological history of the area. “Finding a rock-covered area of pure sulfur is like finding an oasis in the desert. It shouldn’t be there, and now we have to explain it,” said the Curiosity project scientist Ashwin Vasavada of NASA’s Jet Propulsion Laboratory.
Sulfur is usually found as sulfate salts formed by drying minerals in contact with water. But pure sulfur only forms in very narrow conditions, and no evidence has ever been found in regions where such conditions occur on Mars. This discovery shows that important information about the geological history of Mars is still waiting to be discovered.
Sulfur is known as one of the essential elements for life. It is a building block of two essential amino acids that living organisms need to synthesize proteins. However, finding pure sulfur on Mars is currently not evidence of life. However, this discovery raises new questions about the chemical and geological evolution of Mars.
The stone that Curiosity accidentally broke during the search allowed scientists to do a deeper chemical study of the rocks in the Gediz Vallis Channel. The vehicle drilled a hole in one of these stones and collected a sample of powder for analysis. As the rover moves deeper into the canal, it is still working to see what other secrets will be revealed.
The Gediz Vallis Canal is a unique area that sheds light on the history of Mars, like a river bed where water flowed billions of years ago. The rocks here bear traces of the ancient river and provide important information about Mars’ water history. If pure sulfur is found in this region, scientists could reshape the geological evolution of Mars.
The unexpected discovery by Curiosity once again proved how full of amazing things have been found on Mars. Future studies could be an important step towards understanding how this sulfur formation occurs and the unknown geological processes of Mars.
