Archaeologists are particularly interested in what Corona images reveal about areas of the near and Middle East that have undergone rapid development in recent decades, destroying archaeological sites and ancient roads and irrigation systems. [26] A salt plug in the base would dissolve after two days, allowing the capsule to sink if it was not picked up by the United States Navy. The contrast was 2-to-1. The Samos E-1 and E-2 satellite programs used this system, but they were not able to take very many pictures and then relay them to the ground stations each day. in.
