Commander Hadfield is the most well known astronaut since Sally Ride -- and with this, he'll be right up there with Neil Armstrong. If this is viral marketing, then THAT IS EXACTLY WHAT THE SPACE PROGRAM NEEDS! Fun, excitement, exquisite beauty -- that's what Hadfield has been beaming back to Earth for the last five months. I've been following his facebook posts for the last couple months and I was genuinely concerned about the ammonia leak this week and his spacewalk, and so were millions of other people. How many "fans" will watch his live prime-time EDT re-entry tomorrow night after watching this video tonight? How many even bothered to watch the final Shuttle landing? This guy is a bona fide star and we who care about space exploration should be embracing him.
