The Canadian astronaut Commander Chris Hadfield returned to Earth today. He was the first astronaut of the new internet age, in terms of the way he used his earthbound links. As someone born in the 1950’s (yes I know it is hard to believe) to me, the idea of someone circling the earth on a space station sending pictures and videos to his twitter followers is beyond belief. Yet it happened, His final video was a rendition of a David Bowie favourite, you may remember that David Bowie has already made an appearance on this blog, as Colm O’Donnell used a song title of his as the title of an article he wrote (Ch Ch Ch Changes…) http://www.guardian.co.uk/science/blog/2013/may/13/chris-hadfield-the-astronaut-s-best-tweets-photos-and-videos  During his months on the Space Station, Chris Hadfield sent many fabulous photos on his social media feeds, The Guardian page that the above link leads you to has many of his best.  This fragile Earth, seen from a new angle.
