Thanks to NPR’s Science Friday host Ira Flatow and multimedia editor Flora Lichtman for a fascinating look at how those inspiring and iconic images of the earth as seen from space are made. The segment discussed the history of these images since the first “earth rise” photo in 1968; there’s technical information about how the modern images are compiled from datasets, not photographs; and there are even little secrets about how the gaps are filled in. That will appeal to my designer friends! My favorite is the “pale blue dot” segment in the video, in which my hero, Carl Sagan, identified the earth as a “mote of dust in a sunbeam.”
