OSIRIS-REx Bennu sample
After finally opening the stuck lid of the sample tank, NASA can finally display the samples collected by the OSIRIS-REx probe from the asteroid Bennu. NASA’s original mission goal was to collect at least 60 grams of soil and rocks from Bennu, but in fact, the “included” samples outside the jar already amounted to 70 grams, and combined with these in the jar, it can be said to be a bumper harvest.
NASA’s plan is to spend the next two years analyzing “small parts” of these samples. From large to small, it will first analyze the appearance and material of individual soil clods, and then gradually break them into pieces to see Minerals crystallize until finally analyzed at the atomic level. Since the composition of Bennu comes from the most primitive materials of the solar system, it is expected that this will allow us to further understand the distribution of various elements and compounds when the solar system was just born, especially the ratio of carbon elements and water molecules, the cornerstone of life, and even more analysis the key of.
Part of the remaining material will be shared with other scientific teams. Among them, Japan’s JAXA’s Hayabusa 2 detector obtained material samples from another asteroid “Ryuugu” at about the same time, and scientists from the two parties have exchanged information. Sample agreement. Most of the remaining ones will be properly collected for continued research by future scientists.
