More than you think, Japan's space development is ahead of the curve!
In 2018, in order to uncover the mystery of human origins, the Japanese exploration satellite "Hayabusa2" flew to the asteroid "Ryugu" 350 million kilometers away from the earth after a three-and-a-half-year flight, and successfully achieved ground landing and detection, and carried out live broadcast, with a landing accuracy error of only 60 centimeters.
And that's not all, after that, Hayabusa2 also collected samples from the surface of the Ryugu asteroid and brought them back to Earth.
Scientists have compared it to meteorites collected on Earth, suggesting that the Ryugu asteroid was heated in the past, perhaps when it broke away from its parent body.
And the water on Earth may have been brought by these asteroids billions of years ago.
The above content is from "Silent Talk of Japan", but in terms of the "craftsmanship spirit" that the Japanese have always had, there is a question mark anyway.
Even if it is really so powerful, why can't the manned launch technology break through until now?
