During the Apollo missions, astronauts collected rock and soil samples directly from the Moon surface. These samples helped scientists understand the Moon’s age, composition, and geological history. Astronauts carefully gathered lunar material using special tools designed for low gravity. The samples were brought back to Earth and are still studied today by scientists around the world. This scientific work proved that humans could explore another world and return valuable data safely. #space #sp
