What would it be like if you could travel to Mercury in a spaceship, land on its surface, and bounce around in the low gravity? This book takes you on a mission to Mercury. Fly over the second-largest impact crater in the solar system, explore the deep crack in Mercury's crust, and find out why a day last longer than a year on this tiny planet.
