What's the illustrious Chris Hadfield – former commander of the International Space Station – been up to since departing low-Earth orbit? Re-adapting to gravity, for one (Hadfield: "my body was quite happy in space without gravity") and participating in this fantastic press conference, his first since he returned to Earth.

Hadfield kicks off the interview by responding in French, but he goes on to field questions in both French and English, addressing everything from how his neck feels now that he has to hold his head up to the power of social media in space.
