Q: 3.1 — Images of Earth from Space: Testimony of Ten Nations

Since 1946, when the first photographs of Earth were taken from the first rockets, up to today, where live direct images are broadcast from the International Space Station, Earth has appeared spherical in thousands of images.

These images came from dozens of countries: the United States, Russia, China, India, the European Union, Japan, and South Korea. Competing nations spy on each other, agreeing on a single image of a spherical Earth. If it were a conspiracy, how would nations in a cold war agree on it?
