missions around the solar system
"For thousands of years, mankind has looked up at the starry skies and dreamed about slipping the bonds of Earth. Today, humans have traveled into and lived in space, but we're still learning more about this solar system we call home, with its sun, planets, and many moons, asteroids, and comets. . . Young readers [will learn] details about the history of space travel in our solar system, from the earliest experiments and flights to plans for the future"--Provided by publisher.
