The Magic School Bus Out Of This World: A Book About Space Rocks series by Joanna Cole (Author), Bruce Degen (Illustrator) by Jackie Posner and illustrated by Robbin Cuddly. TV script written by Libby Hinson and George Arthur Bloom

This is a TV show spin off. They hear an asteroid is about to crash into the school. They go to see it. In the process the melt a comet. Then they make their bus huge to get the asteroid into orbit, then shrink it to launch the asteroid to the sun. This went heavy on the fiction and low on the science.
