NASA, AS17-148-2272, taken from Apollo 17 mission on December 7, 1972, at 5:39 a.m. ESTWe live on a beautiful, fragile yet amazingly resilient world, which we celebrate on April 22.  It’s the third planet from our star, the sun, formed over four and half billion  years ago from accreting stellar matter, along with the rest of our system.  Life developed rapidly on the new planet, taking merely half a billion year or so, maybe a little more, but took another two billion before jumping to a multicellular arrangement.  All the time, it has branched and multiplied, trying all sorts of crazy strategies to get the edge in survival.  The whole system is an intricately interconnected web stretched around a lovely blue marble.

To the right is the most famous photo ever taken of our world, NASA’s image no. AS17-148-2272, taken from the Apollo 17 mission on December 7, 1972, at 5:39 a.m. EST.  We’re more used to see it reversed, with the South Pole at the bottom.   It was the the first clear image of an illuminated face of Earth we ever received — this was a new trajectory never used before by an Apollo mission — and is sometimes described as the most reproduced image of all times.  (That’s an unverifiable claim, but it’s true that this is a widely known, iconic image.  I posted the South-Pole-up version rather than the more familiar reversed version to remind myself that up and down, north and south, are entirely relative to our frame of reference.

I think I’m going to go listen to Vangelis’ Albedo 0.39 now.
