'Maddy and Jack are flying into space! If you come with them you can turn the countdown wheel from ten to zero and help the rocket "lift-off" by pulling the tab. Now travelling into the solar system, you can lift the flaps to let the planets reveal their secrets, make craters on Mercury with asteroids, spot the "happy face" on Mars, turn the disk to rotate Jupiter's moons, and twist Saturn's rings of ice and rock. Dodge asteroid belts and pull comets across the sky! Finally land safely back on Earth.
'Maddy and Jack tell us simple Did You Know facts, with more detailed information under the flaps.' (From the publisher's website.)
