According to foreign media CNET reports, the asteroid Bennu is the theme of NASA’s Osiris Rex mission, and it seems to have found some unusual “souvenirs”. In a cosmic “CSI” case, < / P > < p > Osiris Rex is currently orbiting the asteroid Bennu in preparation for a bold sample collection operation in October. The spacecraft has sent back a large number of images and data from the debris pile asteroid, which was formed by a large number of collision debris. < / P > < p > the boulders range in size from 5 to 14 feet (1.5 to 4.3 meters) and look significantly different from the dark material surrounding them. After careful investigation of these strange rocks, the researchers found signs of mineral pyroxene on Vesta. After ruling out other possible ways to form pyroxene, the team thinks Vesta is likely to be the culprit. It’s like tracking fingerprints found at a crime scene. < / P > < p > “our main assumption is that Bennu inherited this material from the parent asteroid after a Vesta (debris from Vesta) hit the parent asteroid,” NASA’s Hannah Kaplan said in a statement on Monday. “Then, when the parent asteroid was catastrophically destroyed, part of its debris accumulated in Bennu under its own gravity, including some pyroxenes from Vesta.” < / P > < p > a NASA video gives a lovely animated version of the study, which was published in the journal Nature astronomy on Monday. “Observations show that it’s not uncommon for one asteroid to have material from another,” NASA said. Vesta is a famous asteroid, which was visited by NASA’s Dawn spacecraft in 2011. It is located in the main asteroid belt between the orbits of Mars and Jupiter. Bennu and Vesta are ancient relics of the early solar system. If it goes well, Osiris Rex’s samples could give scientists more clues about the mysterious objects and their origins.
