The Kármán line is a fascinating concept that defines the boundary between Earth and outer space. Located approximately 62 miles (100 kilometers) above the Earth’s surface, this imaginary line holds a significant role in aerospace engineering and exploration. Named after the Hungarian-American engineer Theodore von Kármán, it signifies the point at which the Earth’s atmosphere becomes too thin to provide enough lift for conventional aircraft to stay aloft. Beyond this threshold, the sky transitions into the vast expanse of space, where gravity and atmospheric conditions dramatically change. The Kármán line serves as a marker for human achievements, as reaching this boundary has become a notable milestone for space exploration. It symbolizes mankind’s relentless pursuit of knowledge and the boundless possibilities that lie beyond our planet.
