Ground Control to Major Tom - Planet Earth is Blue, and there's nothing left to do...

Today. the day after astronauts detected and repaired a "serious but not life-threatening" ammonia leak on the space station, Commander Chris Hadfield has passed over command of the space station. Planet earth is blue and there's nothing left to do ... except to release this video. Sorry, Tilda Swinton does not make an appearance. Video is suitable for all audiences.
