Observation of NASA will be launched in September 8th OSIRIS-REx asteroid mission detector sampling results will help scientists to determine Benu may cause a threat to earth, studies have shown that the probability at the end of the twenty-second Century the asteroid has smaller will hit the earth with 400km simulation asteroid Tencent space news according to foreign media reports, NASA officials said that the first effect an asteroid NASA originally planned to launch the sampling task within a week and is not affected by the September 1st SpaceX Falcon 9 rocket explosion. According to the plan, the OSIRIS-REx detector NASA will in September 8th from Florida to Cape Canaveral Air Force Base launch, the Benu near Earth Asteroids (Bennu) were observed for a period of two years. The Atlas V will be equipped with rocket detector according to the original plan 8 EDT 7:05 pm on the launch, and will not be delayed because yesterday SpaceX’s Falcon 9 rocket explosion. NASA officials said yesterday after the explosion on twitter, preliminary checks show that rockets and detectors are still intact, SpaceX is still investigating the cause of the explosion. At the same time, the launch service provider joint launch alliance is preparing its own Atlas V booster for the OSIRIS-Rex detector. If all goes well, the OSIRIS-REx probe will be in July 2018 with a 500 meter wide asteroid Benu meet, and its sampling, and then in September 2023 the sample sent back to earth. This cost about $800 million of the task, the main purpose is to further study as berua such carbon rich asteroids in transmitted to earth life basic component module has played a role in what. The task of scientist Daniel Scheeres said, we believe that Benu is one of the most primitive are rich in organic matter bodies in the solar system. We believe that it is in the early stages of the formation of the solar system, from the original gas distillation. This is also the main reason for the decision. OSIRIS-REx’s observations could help scientists to re evaluate Benu’s possible threats to the earth, and studies have shown that the asteroid at the end of the twenty-second Century had less chance of hitting the earth. Scientist Scheeres said, through close study we can accurately determine the Benu, its orbit, the physical effects of its impact, in order to more accurately predict in the next hundred years of its location. Then we should know if we need to build a huge detector. NASA officials said the mission will survey Benu resources to further investigate the possibility of future asteroid mining. The OSIRIS-REx mission is NASA’s first asteroid sampling mission, but it’s not the first time in history to do such a task. In 2010, Japan’s "Hayabusa" (Hayabusa) task back to the asteroid Itokawa (Itokawa) of the small sample, and launched in December 2014 two, Hayabusa from another space rock sample.
