EDGE OF SPACE Meaning and
Definition
-
The term "edge of space" refers to the boundary that separates the Earth's atmosphere from the vast expanse of outer space. It represents the highest altitude that can be reached by aircraft and serves as a demarcation between the realm of Earth's atmosphere and the vacuum of space. While there is no definitive scientific definition of where exactly the edge of space lies, it is commonly understood to be around 100 kilometers (62 miles) above the Earth's surface.
At this height, often referred to as the Kármán line, the atmosphere becomes extremely thin, with the air density being significantly lower compared to the lower altitudes. The thinning atmosphere is unable to provide sufficient lift to conventional airplanes, and therefore, reaching the edge of space typically requires specialized vehicles such as high-altitude balloons, rockets, or spaceplanes.
Reaching the edge of space holds great scientific importance as it allows researchers to conduct experiments, collect data, and study various phenomena that occur in this unique environment. These scientific endeavors focus on fields like astronomy, atmospheric studies, microgravity research, and technological advancements needed for space exploration. Moreover, the edge of space also serves as a symbolic milestone for human achievements, representing our desire to explore and understand the cosmos beyond our planet's boundaries.
