Planetary surfaces is a research area that focuses on studying the physical characteristics, geology, and surface processes of planets, moons, and other celestial bodies within our solar system and beyond. This field involves using a variety of observational and analytical techniques, such as remote sensing, geological mapping, and numerical modeling, to understand the formation, evolution, and composition of planetary surfaces. Researchers in this area also investigate the presence of water, minerals, and other resources on planetary surfaces, as well as potential habitats for microbial life. By studying planetary surfaces, scientists aim to gain insights into the history and geology of other worlds, as well as the potential for human exploration and colonization.
