According to foreign media reports, Venus may now be the focus of the spotlight, but Mars will not be forgotten in the search for evidence of life outside our planet. NASA’s curiosity rover has finally had a chance to perform a long-awaited experiment aimed at finding organic molecules. Now curiosity is busy on Mars looking for signs that might once have been suitable for microbes. The recent Sam TMAH experiment of the detector marks a new milestone in this research. < / P > < p > it is understood that the subject of the experiment was a piece of powdered rock drilled from a site named Mary Anning, named after a pioneering British paleontologist in the 19th century. < / P > < p > Rovers use their Mars Sample Analysis (SAM) instruments to detect elements such as nitrogen, oxygen, and carbon necessary for life in Martian rock samples. It uses small cups to analyze powder samples. Some of the cups are known to heat rocks to collect gas, while others contain chemical solvents. The TMAH part of the experiment was tetramethylammonium hydroxide. Curiosity has only two tmahs, which makes it extremely valuable on the red planet. < p > < p > NASA atmospheric scientist Scott guzewich wrote on curiosity blog last week: “TMAH will help our scientific team determine which organic material fragments exist in Mary Anning’s clay rich rocks.” After 12 years, “world class Super project” Shantou Bay Tunnel ushers in a historic breakthrough today
