Ever since I was a little boy, I've dreamed of what it would be like to visit space and look down at the Earth below. Sadly, I'll probably never have that experience, but I can live vicariously through astronaut Chris Hadfield, who talked about what it's like on the science video blog Veritasium.
In the clip, Hadfield talks about his very first space walk, where he was on the dark side of the world over the Indian Ocean. There, he got a birds-eye view of the Aurora Australis (aka the Southern Lights) as the ISS basically soared through them. Hadfield said that space gives people a unique perspective, and looking down at the Earth it becomes instantly apparent the effects we're having on our planet.
For example, Hadfield mentions that if you come across cities like Mexico City or Beijing, the pollution from those cities is visible to the naked eye from space. Similarly, the Aral Sea, which was once one of the biggest seas in the world, has virtually dried up over the last few decades, in large part because of agricultural and irrigation policies put in place.
So strap on your virtual spacesuits and take a space walk with Commander Hadfield in the interview at the top of this post. It will probably be the closest you and I ever get to deep space.
