When we meet people who are astronauts or deal in astronomy, it's always really fascinating.
Throughout spaceflight history 18 astronauts have lost their lives during four tragic space flights. 11 other people have lost their lives training for spaceflight.
The ISS has been visited by astronauts and cosmonauts from 15 different nations. There has been a total of 352 flights to the ISS, by 211 individual people, 31 of these were women, and 7 were 'space tourists' (as of 2013).
The ISS comprises pressurised modules for astronauts to live in, external trusses for propulsion, solar arrays for power and many other amazing components.
Sometimes astronauts feel a little ill or get minor scrapes. I trained as a crew medical officer to do basic treatment.
So most astronauts are astronauts for a couple of years before they are assigned to a flight.
Rumours that astronauts can see the Great Wall of China from the Moon with the naked eye are untrue.
Once selected, NASA astronauts spend 20 months training in a variety of areas. To simulate spacewalks and test equipment astronauts often have to train underwater in swimming pools here on Earth.
No, I think most astronauts recognize that the space shuttle program is very high-risk, and are prepared for accidents.
No, ancient astronauts did not build the pyramids - human beings built them, because they're clever and they work hard.
