Understanding the Stratosphere: What Makes It Special?
Before diving into the history and significance of the race to the stratosphere, it’s
important to understand what the stratosphere actually is. The Earth’s atmosphere is
divided into several layers, each with unique characteristics. The stratosphere lies above
the troposphere, where weather phenomena occur, and below the mesosphere.
The Unique Features of the Stratosphere
**Altitude Range:** Approximately 10 km (6 miles) to 50 km (31 miles) above the
Earth’s surface.
**Temperature Gradient:** Unlike the troposphere, the temperature in the
stratosphere increases with altitude due to the absorption of ultraviolet (UV)
radiation by the ozone layer.
