From the box: Designed by Helmut Wimmer one of the world's leading astronomical illustrators, and resident artist at New York's Hayden Planetarium, Space Hop teaches players about the sun and its planets, moons, comets and asteroids. Each participant selects a space craft, and draws a "Mission" card. The "Mission" card indicates the player's objective by describing various aspects of his destination without naming it. There are rules for space travel, hops through hyperspace, "space bumps" and various other maneuvers which make the game exciting to play and highly educational. While a great game to play in the 70's and 80's, much of the information is out of date and the game play is truly child-oriented.
