Turns out they're all archived on NASA's servers and are available to the public for view. Nathan Bergey combed through that archive and pulled the location for all of those 1,129,177 photos. He's created an incredible visual with this data:
|Each dot represents the location of a photo.|
After creating this visualization, he ended up dividing the dots by mission:
|Each color represents a different mission.|
If you're wondering why the purple dots seem to overwhelm the rest of the image, it's because Don Pettit took multiple time lapse sequences—each consisting of hundreds of images—on his mission. His images cause almost uninterrupted orbit lines while the rest of the dots seem to come in randomly. Fun fact: Don Pettit is solely responsible for almost half the images taken in orbit!
