Blue Marble Week is a celebration of #earthsfirstselfie; it is humanity's first whole-earth image from space
It was a profound moment on Dec 7th, 1972 when we realized that we, humanity, had climbed from the trees, across the savannah, and over time, invented the technology to propel us to the stars! It is why this simple picture taken by the Apollo 17 mission matters because it shows both our vast history and our vast potential.
The Blue Marble image is often credited with sparking the global environmentalist movement as it viscerally portrayed the Earth's fragility and immediately elevated interest in climate change and climate science studies. All this is represented in #EarthsFirstSelfie!
