Atmospheric Structure Investigation: Planetary in Situ Measurements of Atmospheric State Including Clouds/Aerosols.

The Atmospheric Structure Investigation (ASI) is a sensor suite designed for descent probes into planetary atmospheres, primarily aimed at Giant planets like Saturn and Uranus, and applicable to Venus, Titan, and Earth-specific missions. ASI aims to provide essential measurements of atmospheric structure, including probe acceleration, rotation, pressure, temperature, vertical winds, aerosol properties, and hydrogen and helium composition, crucial for contextualizing other probe data.
