Long-term observations

Definition

Long-term observations refer to the systematic collection of data over extended periods, often years or decades, to study changes, trends, and patterns in various phenomena. In the context of space exploration, these observations are crucial for understanding the dynamics of celestial bodies, environmental conditions, and the potential for life beyond Earth. They help scientists track the evolution of planetary atmospheres, surface conditions, and other critical factors that can influence habitability.
