The famous traveler Petya Ryzhik and his friends, the dogs Mick and Muk, appeared on the pages of the Soviet children's magazine “Funny Pictures”. They were drawn by the magazine's editor-in-chief, artist Ivan Semyonov. Together with Petya Ryzhik, readers of the magazine from the late 50s to the mid-60s of the 20th century experienced extraordinary adventures, visiting not only various places on the globe, but also in space. The fourth story in this series is dedicated to this journey. For preschoolers and primary schoolchildren.

The text for the drawings was written by me specifically for the e-book and was absent in the printed edition, with the exception of the text on the drawings themselves. My authorship refers only to the text part. The division into chapters and their titles were also made by me.  — V_E.
