Planetary settlements refer to human habitats established on other celestial bodies, such as the Moon or Mars. These settlements aim to support human life by providing essential resources like air, water, and food. They are designed to facilitate scientific research, exploration, and potentially long-term habitation. To create these settlements, advanced technologies are needed, including life support systems and sustainable energy sources. NASA and private companies like SpaceX are actively researching and developing plans for future planetary colonization. The goal is to ensure that humans can live and thrive beyond Earth, expanding our presence in the solar system.
