NASA's programs focus on space exploration, scientific research, and technology development. Key initiatives include the Artemis program, which aims to return humans to the Moon, and the Mars Exploration Program, which sends rovers to study the Martian surface. These programs help expand our understanding of the universe and our place within it. In addition to exploration, NASA conducts Earth science research to monitor climate change and natural disasters. The agency also develops advanced technologies for aeronautics and space travel, such as the Space Launch System and the James Webb Space Telescope, enhancing our capabilities for future missions.
