Science of Aerostats

Aerostats are lighter-than-air craft, such as balloons and airships, that float by using gases like helium or hot air. These gases are less dense than the surrounding air, creating buoyancy. Aerostats can be used for various purposes, including observation, surveillance, advertising, and scientific research. They are tethered or free-flying, featuring large envelopes that capture and hold the lighter gas. The science behind aerostats lies in principles of buoyancy, gas laws, and aerodynamics, enabling them to rise, navigate, and remain stable in the atmosphere. Their ease of deployment and low operational costs make them valuable tools in numerous fields.
