NASA’s Osiris Rex probe will sample the surface of the asteroid Bennu and return to earth. Recently, scientists on the mission introduced new discoveries about the surface material, geological characteristics and dynamic history of the asteroid Bennu. < p > < p > a paper led by Amy Simon of the Goddard Space Flight Center shows that there are widespread carbon containing organic materials on the surface of asteroids, including major mission landing sites. The landing site is where Osiris Rex will conduct its first sample collection attempt on October 20. The results show that hydrated minerals and organic matter are expected to be present at the landing site. The researchers hope that the study of organic molecules will help answer questions about the origin of water and life on earth. < / P > < p > scientists are optimistic that the abundance of carbonaceous materials means that spacecraft will sample them and send them back to earth. The team also found that many of the giant rocks and rocks on the surface of the asteroid had bright veins that appeared to be carbonate. Some of these rocks are located near the Nightingale crater, suggesting that carbonate may be present in the returned samples. The presence of carbonates has led the team to believe that bainu’s parent asteroid probably had an extensive hydrothermal system in which water interacted with the parent rock and altered the parent rock. The veins in some of the asteroid’s boulders are feet long and inches thick, which scientists say confirm the hydrothermal system the size of the parent asteroid. < / P > < p > the team also found that rocks near the Osiris Rex landing site were exposed to harsh space conditions. This means that the & quot; bernu will collect and return the most primitive material on the asteroid. Another paper distinguishes two major types of boulders on asteroid surfaces, dark and rough, and bright and smooth. They believe that the two different types of rocks may have formed at different depths of the asteroid’s parent body. Dark and rough porous rocks will be destroyed when they enter the earth’s atmosphere and may not have been seen in meteorite samples collected on earth.
