Keith's note: There is no mention of this amazing photo (or many other stunning photos) to be found at this NASA.gov ISS gallery page or at Scott Kelly's Flickr, NASA2Explore Flickr, NASA_JSC_Photo Flickr, NASA Earth Observatory Flickr, etc. No higher resolution version, no mention of what part of Earth's surface is shown, when it was taken, etc. To be certain having crew members tweet things from orbit to 13.5 million people is great - but so many chances to vastly enhance this reach are missed every day.
Yes, I am complaining about the way NASA sends pictures from space (more or less directly) to my iPhone many times a day. NASA could be spreading this magic elsewhere so very easily.
