The World's Largest Copper Mines are Visible from Space
From orbit, the Earth often appears pristine, vast oceans, dense forests and sprawling cities. But in some places, human industry has left marks so large that they are clearly visible from space. Among the most striking examples are the world’s largest copper mines. Carved deep into the Earth through decades of large-scale extraction, these open-pit mines stretch across kilometres of land, forming enormous, stepped craters that can be identified even in satellite imagery. Their scale reflects both the global demand for copper and the remarkable hashtagengineering required to extract it.
One of the most striking examples is the Bingham Canyon Mine, located southwest of Salt Lake City, Utah, in the United States. Often referred to as the Kennecott Copper Mine, it is the largest human-made excavation on Earth and one of the deepest open-pit mines in the world. The pit measures roughly 2.48 miles (4 km) wide and more than 0.74 mile (1.2km) deep, which is taller than two Empire State buildings stacked on top of each other. Its enormous size makes it visible from space and even to astronauts orbiting the Earth. Satellite images captured by hashtagNASA clearly show the mine’s distinctive terraced structure carved into the mountains.
Another example is the Chuquicamata Mine in the northern Chile’s Atacama Desert, second only to Bingham Canyon in Utah. This site is one of the deepest open-pit copper mines in the world and has dramatically reshaped the surrounding landscape. Evidence of hashtagmining here dates as far back as the sixth century C.E., but the modern era of mining began in the 1910s. The pit reaches depths of nearly 1,000 metres (3,300 feet), and its terraced benches appear as concentric rings in satellite imagery captured by Landsat satellites. These visible “scars” on the hashtagEarth’s surface illustrate how decades of copper extraction have hollowed out the terrain.
Such hashtagmines demonstrate the immense engineering capabilities required to extract critical hashtagminerals that power modern technologies, from electrical wiring and renewable energy systems to smartphones. Their visibility from space is not only a testament to their scale but also a reminder of how deeply human industry can reshape the planet’s surface.
