India’s Near-Space Ambition Takes Shape as Red Balloon Aerospace Tests Super-Pressure Balloon
A super-pressure balloon is not an ordinary weather balloon. It is a specialised high-altitude platform designed to maintain internal pressure greater than the surrounding atmosphere, allowing it to remain stable at high altitudes for longer periods. Such balloons operate in the stratospheric or “near-space” layer, roughly between conventional aircraft altitudes and satellite orbits. This makes them useful for missions where satellites may be expensive and drones may lack endurance.
