Dragon, SpaceX, go for launch.

Hello, I'm Luke Jones.

Welcome to the documentary from the BBC World Service.

In BBC OS conversations, we bring people together to share their experiences.

This time, we're heading out of this world to bring together astronauts.

If you were born after November 2000, for your entire life, there has always been someone living up in space.

So the first two of the International Space Station has reached their home.

That first crew arrived at the International Space Station 25 years ago.

And since then, almost 300 people from some 20 nations have visited the orbiting lab.

Later, as the United States begins its return to the moon for the first time in over 50 years,

we will discuss what the future holds for humans in space.

But first, two astronauts who have lived on the ISS have been sharing their experiences with my colleague James Reynolds.

British European Space Agency astronaut Tim Peake launched to the space station 10 years ago,

where he lived for six months, and NASA astronaut Nicole Stott has flown to space twice,

spending a total of 104 days in orbit.

It felt like I was coming to a second home when I got there almost immediately.

And of course you adapt, right?

You are floating and you're adapting to this new environment.

But there's something to getting used to moving in three dimensions and floating and flying

and having that extraordinary view out the window.

It's like nothing else.
