No astronauts have ever been to Mars, and no rock samples have ever been sent to 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.
When astronauts go on missions they come back with a few specs of stardust.

The lunar module that carried Neil Armstrong and Buzz Aldrin to the surface of the moon and back to the command module was called 'Eagle". The command module that remained in orbit around the moon and eventually carried all three astronauts back to earth was called "Columbia".
Astronauts returned to the earth in the main spacecraft called Apollo11.

The word that describes Jesus coming to earth is called the rapture. Rapture means, "to transport (a believer) from earth to heaven at the second coming of christ." I hope this helps!
No... they went to the moon, didn't undergo a lobotomy. There is no reason for astronauts to loose their memories when they returned to earth.
they used a module that carried them back
Astronauts cannot shower and use the bathroom the way that we do on earth. Astronauts have to reuse the water.
The Apollo 13 astronauts used the lunar module to return to earth.
They brought back moon rocks to earth.
Astronauts eject their poop out of their spaceship. It doesn't pollute space so it's better than bringing it back to Earth.
No astronauts have ever been to Mars, and no rock samples have ever been sent to Earth.
No
Yes apollo 13 did make it safely to earth with all the three astronauts.
