Surface
In space and astronautical engineering, surface refers to the outermost layer of a celestial body, such as a planet, moon, asteroid, or comet. The study of surfaces is important for understanding the geological and physical properties of these bodies, as well as for planning and executing missions to explore them. Surface features can include mountains, craters, valleys, plains, and other formations, which can provide clues about the body's history and composition. Surface exploration can be done through remote sensing techniques, such as imaging and spectroscopy, or through direct contact with the surface, such as with rovers or landers. Understanding the surface of celestial bodies is crucial for advancing our knowledge of the solar system and for preparing for future human exploration missions.
