NASA will sample asteroid explore the solar system to find clues to life on earth – Science

NASA will sample the asteroid   explore the solar system to find clues to the earth’s life – Science and technology – People’s original title: NASA will sample the asteroid OSIRIS-Rex detector will collect samples from the planet. Photograph: NASA 12 years ago, the United States University of Arizona scientist Dante Lauretta meteorite is just emerging, a breakthrough on the heels. His team is mainly responsible for the analysis of carbon rich meteorites, and found a little bit of three phosphate, which provides energy for life. But because of the pollutants, the team can not be separated, for example, a septic tank from Australian meteorite. Lauretta needs something more pure. Soon, the tutor Michael Drake phone came. He said the company plans to Lockheed Martin? NASA (NASA) to build a detector, the detector will travel to the asteroid, and carrying the fresh samples back to earth. Drake asks Lauretta if he can work out a scientific plan for it? Lauretta’s answer is yes. "I’ve been doing this job for the next year." He recalls. In September 8th, at a cost of $1 billion for the OSRIS-Rex detector will be launched with the will of Lauretta flight to "Benu bird" asteroid surface sample collection. Although it is not the first asteroid dust returned to earth carrying aircraft — in early 2010 the Japanese Hayabusa 1 detectors had carried thousands of dust back to the ground, but scientists believe that OSRIS-Rex detector in 2023 will bring back the earth a gift: it carries the sample will provide a new perspective for other amino acids bring the structure and understanding of the solar system asteroids hit earth organic molecules. The NASA Goddard space flight center equipment scientist Dennis Reuter said the OSIRIS-Rex detector’s mission is to explore the solar system the original composition, and to the formation process of the solar system also announced, will collect the samples back to earth asteroid. "We will have a valuable scientific treasure." Lauretta says. In 2011, after Drake’s death, Lauretta became the main investigator of the project. Related samples come from the asteroid Benu bird. This "B" is the asteroid 700 thousand asteroids through the solar system in one, will it as a target survey since it is closest to the carbonaceous asteroids. Its orbit is sometimes as close to the earth as the moon, so astronomers have studied it very well. However, there are still many mysteries Benu bird asteroids. Johnson Space Center NASA scientist Mike Zolensky said the cosmic dust, for example, it can reflect a little blue, showed that organic molecules have occurred in the past the event may damage the desired. In order to collect samples from the asteroid’s surface, the probe will be circling in a particular area and very slowly相关的主题文章:
