The Black Dinosaurs have always explored the past in their adventures, but now they're going into the future -- to Space Camp! They'll learn what weightlessness feels like, what astronauts eat, even how they go to the bathroom! Ziggy, of course, really wants to meet up with aliens -- purple, three-headed, fire-spitting Martians like the ones in his Mega Mighty Martian Blaster game.

Ziggy soon discovers that real-life space travel is just as exciting as anything even his active imagination can cook up. Still, he can't help wondering where the mysterious shiny stone he finds might have come from. . .
