The desire of mankind to explore space is unlimited. As long as the opportunity is suitable and well prepared, we will make bold attempts. Through adventure after adventure, our understanding of the universe has become clearer and clearer. One day human beings can step out of the earth and enter the interstellar age through their own efforts. According to a foreign media report on October 23, the US National Aeronautics and Space Administration NASA has once again completed an amazing feat, successfully working together A stone sample was taken on the flying asteroid.

NASA said, This is the first time that mankind has successfully taken a stone sample of an asteroid, which will help us understand the origin of the universe. Scientists point out that every asteroid has its own story. How it formed and how it evolved is worth studying. The asteroid selected by NASA this time is called”Benu“, which is carefully selected by NASA from 500,000 asteroids The main reason for choosing”Bennu” is that its orbit is close to the orbit of the earth orbiting the sun, and its size is also very suitable for scientific research.

I want to It is not an easy task for the”Benu” star to collect samples. The distance control is very strict. It cannot be taken if it is far away, and it may be directly destroyed if it is close. If you want to successfully collect samples, you must do”one touch Li”, complete all work in ten seconds. According to NASA, in order to complete this plan, they have prepared a full 12 years. The”Osiris” unmanned probe can successfully complete the task, and has made unimaginable efforts.

at a distance from the earth At a distance of 330 million kilometers, NASA used the”Osiris” unmanned probe to approach and briefly touch the”Benu” star, staying on the”Benu” star for 16 seconds. In these 16 seconds, the”Osiris” unmanned probe quickly launched operations and collected approximately 60 grams of surface material. It is estimated that in 3 years, these tens of grams of samples will be sent to the earth and enter the scientist’s laboratory. Through these dozens of grams of samples, humans may discover many secrets of the universe, thus opening a new chapter in human exploration of the universe.

When the management center heard the sound of”successfully landed and sampling”, the scientific researchers present burst into cheers . This is really not easy. If this mission fails, I don’t know how many more 12 years it will take to perform another mission. For scientists in certain related fields, the significance of this”touch and leave” mission is no less than an Apollo moon landing.
