As far as has been made public, all astronauts of any country have been trained on earth, began their space missions on earth, and returned to earth at the conclusion of their missions. Astronauts have died during launch or re-entry. None have been lost or died in space. So the answer to the question is: Yes, 100%, every known astronaut has been to earth.
In fact, if you want to round things off, every astronaut has spent approximately 100% of his life on the earth, and approximately zero in space.
Astronauts.
None They have only been to Moon of Earth
No astronauts have ever been to Mars, and no rock samples have ever been sent to Earth.
The only planet astronauts have visited is earth. The moon, a satellite, has also been visited.
At the moment, Astronauts cannot go to any planet but Earth.
No. Astronauts have never been anywhere near any astronomical bodies except Earth and the Moon.
The only planet humans have ever been on is Earth.
When the Apollo astronauts were in orbit around the moon they were the furthest any human had been from the earth.
As astronaut travels into outer space and some have been killed doing so. Most astronomers stay on the planet Earth and look up into space. There have been astronauts who are astronomers, but, most astronomers are not astronauts. There have been tens of millions of astronomers looking up at outer space, but, only a few hundred astronauts. No, they are not the same.
No. Astronauts have orbited over the far side of the moon, but have never landed on it. The main reason is that they would be unable to communicate with Earth.
All the astronauts used by N.A.s.A have walked on the surface of the earth.
The only place astronauts have been other than Earth, is on the moon. When they were there, they did some exploring to see what it was like. They took samples of the soil and rocks to bring back to Earth. They tried to learn as much as they could while they were there. If astronauts get to visit other planets, they would do the same kinds of things.
