Aerostats

Aerostats are lighter-than-air structures that float in the atmosphere, typically using gases like helium or hot air to achieve buoyancy. Commonly found in applications such as surveillance, weather monitoring, and telecommunications, they are often tethered to the ground to remain stable. Unlike airplanes, which rely on wings and engines to fly, aerostats maintain their position by being filled with a gas that is less dense than the air around them. Their ability to hover at low altitudes makes them valuable tools for various industries, providing a stable platform for observation and communication.
