Sky Balloon

A Sky Balloon is a large, usually helium-filled balloon designed to ascend to high altitudes, often used for scientific research, weather monitoring, or atmospheric data collection. It can carry instruments and sensors to gather information about the upper atmosphere, space environment, or weather phenomena. As it rises, the balloon expands with decreasing atmospheric pressure, allowing scientists to study conditions at various heights. Once its mission is complete, the balloon typically descends back to Earth, sometimes with a parachute, to retrieve the collected data or equipment.
