However, while in the belt, one of the bus's tail lights is damaged by an asteroid and the Friz flies out to fix the tail light with a tether line connecting her to the bus. Frizzle then takes them to the Sun and then Mercury, Venus and Mars before flying into the asteroid belt. Once in outer space, the bus flies to Earth's Moon, where the kids make the most of the lesser gravity. Frizzle pushes a button that makes the bus transform into a rocket and blast off into outer space. But once they get there, they find the planetarium is closed for repairs. The Friz decides to take the kids on a field trip to the planetarium. Frizzle's class is learning about the Solar System and Arnold's unpleasant cousin Janet, who constantly raves about herself, has joined them.
