Chris Hadfield speaks to 820 students live from space

On January 17, 2013, Chris Hadfield took part in a space to ground connection with some 820 students gathered at the Chris Hadfield Public School in Milton, ON, his hometown. With the help of fellow Canadian astronaut Jeremy Hansen hosting the event on the ground, Hadfield answered student questions and even played a little guitar while floating some 380 km above the Earth aboard the International Space Station.
