Harrison wants to go to space, but first he’ll have to learn how to float in zero gravity, sleep “standing up,” and figure out how a rocket works. Fortunately, he knows some real astronauts who can help him out. “Can kids go into space?” Challengers in a “zero gravity” rig compete to see who can fix a broken satellite the fastest. At the Canadian Space Agency, Harrison samples astronaut food and learns how to “catch” a delivery of space groceries with the Canadarm2 robotic arm.
