Earth Observation

iss069e033759 (July 17, 2023) -- As the International Space Station orbited 260 miles above Turkey, NASA astronaut Woody Hoburg captured this image of Lake Tuz—a disappearing lake that was once the second-largest in the country. During some summers, the salt lake completely dries up, leaving the off-white appearance of higher concentrations of salt and minerals. What's left of the lake experiences seasonal color changes due to algae blooms, like the deep red shown near the bottom center of the image.
