Planetary robotics involves the design and use of robotic systems to explore and study celestial bodies beyond Earth, such as Mars, the Moon, and asteroids. These robots can gather data, take images, and perform experiments in environments that are often too harsh or distant for human exploration. They play a crucial role in advancing our understanding of the solar system. Robots like the Mars rovers and lunar landers are equipped with various tools and instruments to analyze soil, rocks, and atmospheric conditions. They help scientists gather valuable information about the history and composition of these celestial bodies, paving the way for future human missions and potential colonization.
