According to the report of the British "Daily Mail" website on July 6, the latest research shows that the American "Cursic" Mars rover, which is good at drilling, can discover complex organic molecules only by digging several inches on the surface of Mars and prove it on Mars. There was life. Some scientists, including Jeremy Merosh, a scientist at Purdue University in the United States, believe that Earth's life originates from Mars and it is equipped with an asteroid to come to Earth.
The size of the car's curious Mars, launched by NASA on November 26, 2011, will arrive on Mars on August 6 this year. The rover equipped with drilling technology can dig down to about 4 inches (about 10.16 centimeters) underground, enough to discover the basic material that builds life.
Complex organic molecules can be more powerful to indicate that there was life on Mars. These molecules usually consist of 10 or more carbon atoms and are comparable to the raw materials that make life, such as the amino acids that make up proteins.
Alexander Pavlov, head of Mars Life Detection at NASA’s Goddard Space Flight Center, said: “The biggest problem is that the previous Mars probe did not find any form of organic matter, and we determined that there must be organic matter on Mars. But it cannot be found in its surface soil."
Compared to the previous Mars Rover, the "Curious" Mars, although not equipped with shovels, possesses drilling technology capable of collecting samples of earth and rock below 3 inches (about 7.62 centimeters) of the surface of Mars, processing and classifying the samples and sending them separately. To vehicle test chamber with analytical instrument. In the past, the rover could only collect loose soil on the surface. Because the soil is directly exposed to cosmic radiation, it is difficult to detect organic molecules in such surface samples.
The mission of the “Curious†Rover is to investigate whether the conditions of Mars are suitable for the survival of micro-life, and to collect clues to life that may exist on Earth from Mars. (Xinlian)
