Una aventura espacial: el vuelo de Mariposa

The earth is in danger! Garbage pollutes seas and rivers. Smoke from factories and cars makes the air unbreathable. Nuclear waste takes up more and more space and endangers the existence of all living beings...
Until it's time to say enough is enough and find a solution to the problem. It is decided to assemble the group of the Thirty Thousand, made up of the thirty thousand wisest people on Earth. After more than two years of deliberations, they come to the conclusion that we must look for another planet where humanity can start anew.
With this mission, the wise Professor Mollete, Captain Irina, Fula, Karkin, Nari-Nari and little Ainu take off into space in the Mariposa ship, on a journey that will allow them to get to know the planets that make up the solar system.

After many dangerous adventures, they manage to return to Earth with a very clear message for humanity.
