SPACE SCIENCE

Space science is a multidisciplinary field that studies the universe beyond Earth's atmosphere. It combines physics, chemistry, astronomy, biology, and engineering to explore celestial bodies, phenomena, and the broader cosmos. Space science encompasses both theoretical studies and practical applications like space exploration, satellite technology, and extraterrestrial life investigations.

Here’s an overview of key topics in space science:
