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:
"How do you experience time?"
In this episode, Luca Parmitano tells us more about time perception in the International Space Station.
