A traveling penguin from the South Pole and a funny polar bear from the North pole meet on arctic sea ice.  They become friends observing the night sky together and wondering why night is so long at the poles of the Earth. This mystery leads them on a scientific adventure by building an improvised spaceship to travel around the Earth to learn about seasons, visit Mars and Saturn to learn about ice in the solar system and how planets have similarities and differences which make them unique.
