Asteroid sample Fetched by NASA Scientists reported on Wednesday, reported by scientists, not only have a lifelong builting block, but also have salty archeological sites in the ancient water world.
The survey results provide Still the most powerful evidence The asteroid planted the seeds of life on the earth, and these ingredients may have been mixed with almost correct water from the beginning.
“It’s an environment that was indispensable for the steps that lead from elements to life,” said Tim McCoy, one of the lead research authors of the Smithsonian Association.
NASA OSIRIS-REX SPACECRAFT Returned 122 grams of dust and pebbles from the nearby asteroid Benne, Sample canister In 2023, he died after another space lock toward the Utah Desert. It remains the biggest transportation of the universe over the moon. In the two previous asteroid sample missions by Japan, the materials have been considerably reduced.
The valuable black grains of a small amount of benzes have been kicked out by two separate research teams with research in the natural and natural astronomy of the journal. However, it was enough to confirm the existence of amino acids and nitrogen, even in the ammonia, and even a part of the genetic cords, with sodium rich minerals.
Similar to the dried lake bottom of the California Mohabe Desert and Africa’s Sahara, but not all of the delicate salt found in Benne, it is stripped of a drop MET stone.
“This discovery was possible only by analyzing samples collected directly from the asteroids and being carefully preserved on the earth,” said Yasuhito Sekine, a science and science research institute, which was not involved in research. I am telling the editor.
Combining the ingredients of life and a salted water, which is rich in sodium, or salt water environment, “It’s really the way to life,” said McCoy, a MET stone curator at the National Museum of Natural History. “These processes probably occurred much earlier and much wider than I thought before.”
NASA’s Daniel Gravin said that one of the biggest surprises was that the richness of nitrogen, including ammonia, is relatively high. All organic molecules found in the Bennu sample have been identified earlier with metal stones, but glavin stated that Bennu is effective.
Bennu -The tile RUB mountain, which is only one -third (half a kilometer of 1 km), was a much larger asteroid covered with other cosmic. The latest results suggest that this body has a wide range of underground networks of lakes and sea, evaporating water, leaving salty clues.
The 60 labs around the world are analyzing Benne’s bit as part of their first research, and the University of Dante Lawletta of Arizona is the chief scientist of the mission that participated in both research. 。
Most of the $ 1 billion mission cache is secured for future analysis. Scientists emphasize that more tests are needed to better understand Benne’s samples and to better understand the returns of many asteroids and comets. China will launch an asteroid sample return mission this year.
Many are seeking the mission of collecting rocks and dirt from the potentially flooded unemployed planet Ceres in the main asteroid belt. Jupiter’s moon Europe and Saturn’s Moon Enkelladus are also invited as an attractive water world. On the other hand, NASA has a core sample waiting for a pickup on Mars, but the delivery is stored while the space agency is studying the most quick and inexpensive way to get them here. 。
“Are we alone?” McCoy said. “That’s one of the question we are trying to answer.”
