live techno One of the fundamental questions astronauts can ask is, is it possible to see man-made objects from outside Earth’s atmosphere?
To answer that question, we need to determine where Earth’s atmosphere ends and outer space begins. This region, called the Karman Line, is considered the boundary between Earth and space and is located 100 kilometers (62 mi) above Earth’s surface.
In fact, there are many man-made places that can be seen from space, the site quoted spaceMonday, July 25, 2022.
For example, the Bingham Gorge mine, located about 20 miles (32 km) southeast of Salt Lake City, is the largest man-made excavation site ever built and is also the world’s deepest “open pit” mine.
The mine is so large that it is visible not only from the Karman Line, but also to astronauts aboard NASA spacecraft, which orbit between 190 and 330 miles (305 to 531 km) above sea level.
Second, the Three Gorges Dam, which runs along the Yangtze River in China. The dam is the largest electricity generating facility in the world and is considered the most expensive hydroelectric dam ever built.
Also in attendance is Dubai’s Palm Jumeirah, which can also be seen from the Carman Line. In addition, using an 800 mm (31 in) lens, the artificial islands can also be clearly seen from the International Space Station (ISS), which orbits at an average altitude of about 250 miles (400 km) above sea level.
