NASANASA 将于 9 月 8 日发射小行星采样任务探测器

OSIRIS-REx observations could help scientists to redefine the threat may cause the Earth Bernoulli, studies have shown that in the late 22 century, there is a small probability of the asteroid will hit Earth

NASA officials said, NASA had planned to launch in the first week of the asteroid and sampling task will not be September 1 SpaceX's Falcon 9 rocket explosion. According to the plan, NASA's OSIRIS-REx will probe launched September 8th from Florida Cape Canaveral Air Force Base, near-Earth asteroids Bernoulli (Bennu) observed for two years. Atlas V rocket carrying the probe will be at 7:05 pm EST on the 8th minute launch as originally planned, and not because of an explosion yesterday SpaceX's Falcon 9 rocket postponed.

NASA officials yesterday after an explosion on Twitter said a preliminary examination showed that the rocket and the detector are still intact, SpaceX company is still investigating the cause of the explosion. Meanwhile, the launch service provider United Launch Alliance is preparing its own Atlas V booster for the OSIRIS-Rex detectors. If all goes well, OSIRIS-REx will probe in July 2018 with a 500-meter-wide asteroid Bernoulli meet, and its sampling, followed in September 2023 samples returned to Earth. The cost of about $ 800 million mission, the main purpose is to further study such as Bernoulli carbon-rich asteroids in the transmission element basic building blocks of life to Earth during the module What role.

The mission scientist Daniel Scheeres said that we believe that the presence of Bernoulli is one of the most primitive celestial rich in organic matter in the solar system. We think it is formed early in the solar system, distilled from the raw gas. This is the main reason for the decision to carry out the task. OSIRIS-REx observations could help scientists to redefine the threat may cause the Earth Bernoulli, studies have shown that in the late 22 century, there is a small probability of the asteroid will hit the Earth. Scientists Scheeres said that through close study of Bernoulli, we can accurately determine their orbits and found that its impact on the physical effects, in order to more accurately predict the next few hundred years of its location.

At that time we should know if you need to build a huge detector. NASA officials said the mission will investigate Bernoulli have the resources to investigate further the possibility of future asteroid mining. OSIRIS-REx mission is NASA's first asteroid sample task, but it is not the first time in history for such tasks. In 2010, Japan & ldquo; Hayabusa & rdquo; number (Hayabusa) task back to the asteroid Itokawa (Itokawa) of small samples and launch Hayabusa II from a different space rocks in December 2014 on sampling.

NASA collected many of the tasks in the past, back to Earth samples of other types, for example, begins with Apollo astronauts on the moon rocks brought back a lot, as well as the origin of the Stardust spacecraft and probe the solar wind were taken grain samples and samples of comet particles.
