I want to know some information about astronauts

發問:

I want to know the number of people that went to Earth, and the number of people that came back unharmed.

最佳解答:

I am not sure what you are asking, hope the following information hope you. As of 2006, a total of 450 astronauts, cosmonauts, and taikonauts who have flown above the internationally recognized 100 km boundary of space. Space disasters, either during operations or training, have killed 18 astronauts and 4 cosmonauts (5% of all people who have been in space, 2% per flight), and a much larger number of ground crew. Only 428 astronuts came back safely. More, however, fatal accidents in which ground personnel were killed were greatly more than that astronuts killed in space disasters. There were more than 230 ground personnel killed.

其他解答:

People are born in Earth. So no one really went to Earth. Number of people came back to Earth from Earth = Error8758B59A7FA1EEA7
