Speaking of treasures, you might think of graves buried deep underground or shipwrecks submerged in the deep sea, but if we look away from the earth, you will find that the universe is simply a place where treasures fly. Countless asteroids travel through the universe. At present, humans have observed more than 20,000 asteroids around the earth. There may be precious precious metals on asteroids, such as gold and diamonds, or collection of the deepest secrets of the universe, and it is of great value for humans to understand the universe.

Exploitation of asteroids has become an ongoing matter in countries such as the United States.

Today we are going to introduce you to an asteroid that has been”dusted” for 4.5 billion years. It has the first secrets of the solar system’s birth and is known as being able to Uncover the”treasure” of the mystery of the birth of the solar system. It is the Benu asteroid.

The first discovery of the Benu asteroid by humans was in 1999. The discovery of this asteroid made earth scientists worry. Because according to scientists’ predictions, the Benu asteroid will approach the Earth at the end of the 22nd century, with a probability of 1/2, 700 collisions with the Earth. Its diameter is about 500 meters. If it collides with the earth, it will bring disaster to the people on the earth. Every six years, the Benu asteroid passes through the earth’s orbit, and people can find its traces in the night sky, which is very mysterious.

With the scientists’ research on the Benu asteroid, we found that this asteroid actually formed in the early stage of the solar system, so the research value is huge. In order to prevent possible dangers and study it, NASA launched the asteroid sampling spacecraft”Osiris-REx” in 2016. Osiris is the”Pluto” in ancient Egyptian mythology. Planetary concerns.

After more than two years of flight, the Osiris-REx” finally arrived at the Benu asteroid in December 2018. Scientists soon discovered that There are traces of water on the asteroid Nu. According to NASA’s plan, the”Osiris-REx” will sample Benu asteroid in the second half of 2020, and is currently looking for a suitable sampling location.

If all goes well, we will receive a cosmic express weighing approximately 46 kg in 2023, which will uncover the mystery of the asteroid Benu for us.
