Ask Our Astronaut: In space, how do you experience time?

We asked for your questions to Euronews space correspondent and European Space Agency (ESA) astronaut Luca Parmitano.

More than one hundred questions were sent in from around the internet – Facebook to Twitter, Instagram to Reddit. They ranged from the sublime – Juliette, aged 10, asked which of your five senses do you use the most in space – to the ridiculous: “How do you fart in space?”

Luca has chosen his favourites and will be answering in a weekly series called Ask Our Astronaut.

Here is a Reddit question from @drunkhussar:

In this episode, Luca Parmitano tells us more about time perception in the International Space Station.
