When Chris Hadfield was nine years old, he watched Apollo 11 land on the moon and decided he wanted to become an astronaut.

That was in 1969, and about half a billion people around the world watched the same grainy images of the moon landing on TV.

It seems incredible, but with today’s technology and social media websites, people can see and hear what the astronauts are doing on the International Space Station every day.

We can watch videos of them, check out the view of Earth from the space station, and even have casual “conversations” with the astronauts.
