Super Pressure Balloon (SPB)

A Super Pressure Balloon (SPB) is a specially designed high-altitude balloon that maintains a consistent size and shape by controlling internal pressure. Unlike traditional balloons, which expand and contract with temperature changes, SPBs use a robust, pressure-stable envelope to resist these fluctuations. This allows them to stay at near-constant altitude for long durations, making them ideal for scientific research, atmospheric monitoring, and technology testing. Their ability to maintain stable flight levels in the stratosphere enhances data collection and mission reliability.
