MILAN - A few weeks ago, half a million people watched him brush his teeth. Two million people discovered that tears don’t run down his face. Four million watched him squeeze a soaking-wet dishtowel.

Meet Colonel Chris Hadfield. He’s Canadian, 53, and very proud of his mustache. Yet something differentiates him from all other people on earth – he’s not on earth. Hadfield is living on the International Space Station (ISS). It’s from there that he has become a huge star on the Internet, through videos, interviews, tweets -- and even songs.

The former Royal Canadian Air Force pilot is now a regular up in orbit. His first missions were back in the Shuttle-era – 1995 and 2001. In March he took over command of the ISS – and it is the first time a Canadian is in charge. This long-duration Expedition 35 mission is being documented by the commander on the Canadian Space Agency’s YouTube account, as well as on Hadfield’s personal Twitter account – turning him into the “Internet’s favorite astronaut.” 

The themes that Hadfield deals with are a mix between science and everyday life. The videos taken on the ISS tell us about life in zero gravity, but always keep a scientific tone. How do astronauts sleep? How do they shave? How do they make a sandwich? Each question is answered on YouTube, and he has even taken part in a Reddit Ask Me Anything.

 

Music is Hadfield’s hobby and in February he became the first person to partake in a live earth-space duet, singing and playing with his compatriot Ed Robertston of the Barenaked Ladies and a children’s choir down in Toronto. The song was called ISS – Is Someone Singing? 

 

And then, there are all the photographs. Published daily, and punctually, via Twitter, they form an incredible diary-in-progress. The photos vary from a colleague going on a space walk to a view high above Berlin. This multimedia documentary will continue on until the end of May, when the astronauts from Expedition 36 take over. 

But, before then, maybe there will be enough time for a new “twittersation” between Hadfield and William Shatner, who played Captain Kirk in the Star Trek series. “Are you tweeting from space?” inquired Shatner at the beginning of January. Respectful of fantasy hierarchy, Hadfield immediately tweeted back, “Yes, Standard Orbit, Captain. And we're detecting signs of life on the surface,” confirming that even without gravity, a joke on Twitter is irresistible.
