The moon

On July 20, 1969, astronauts became the first humans to step onto the moon, a milestone that still stands as a high point in the story of spaceflight. Researchers have kept studying Earth's only natural satellite ever since.

The book describes what it feels like to move across the moon's surface and explains the part the moon plays within the solar system. It also traces how early observers began to study the moon and shows the ways scientists continue to explore it today.
