This is a tough one to come up with a correct translated title. Could also be:
"Still far from Earth"
"Until the earth is still far"
So I will go with my made-up one:
Lyashenko, Mikhail and Svirin, Alexander. Illustrated by B. Markiewicz and Grishin. Until the Earth is Far. Moscow: .100p. 30 cm. (part of "Books of Knowledge" series, Book 1.)
This was part of an "encyclopedia" for children which too a fictional story and filled it with scientific facts. Other topics in the series were "On this planet can live", "Operation Ocean", "Big Hunt", and "expedition to the ancestors."
These are widely known children's classics in Russia and have bee reprinted in both 2010 and 2016.
Having no russian language I speculate we once again have a group of children traveling with a scientist uncle or friend as they explore the solar system in their space craft.
The illustration are wonderfully fanciful and suggest how fantasy and reality can be shown together.
I have encountered these "wings" in some other russian children's books. I don't know if this was a concept developed earlier than this but it seems interesting.
I will continue with illustrations from this book with my next post.
