Successfully mine! NASA probe succeeded in sampling Bennu asteroid and returned to Earth three years later

There are many asteroids in the solar system. For us humans, they are all rich mineral deposits that can be used in the future. In the future, humans can mine on asteroids, emigrate asteroids, or transform asteroids into interstellar. Spacecraft, but at this stage, we can only make observations and measurements on asteroids. We are in the stage of scientific research and exploration. At most, we are sampling from asteroids and returning to determine the matter on it.
