We all like to get a fresh haircut and it's no different for astronauts living in space.
But it's a bit more tricky to do in zero-gravity.
Samantha got a haircut on the ISS by her Nasa colleague Terry Virts while cosmonaut Anton Shkaplerov had to hold a vacuum cleaner, making sure that no hair cuttings float off.
Samantha posted updates on social media saying: "New Year, time for a haircut. Setting up shop at 'Chez Terry'".
