According to Wikipedia:
During 1985-1986 a popular science magazine Tekhnika Molodezhi published a science fiction story Way to Earth accompanied by programs for B3-34 that could be used to simulate a particular segment of Moon-Earth journey from the story.
For example, according to Google translate of Way to Earth (the translation explains the story and is already fascinating to read), there are subjects such as Lagrange, aerodynamic braking, mascons, and more.
I wonder whether any translations exist of this story: I would like to discover the space navigation math that was used in these stories.
I think this page is the first of the complete set, which would make 1985/6 the first magazine and 1986/8 the last.
As a (possible) side issue, "Lunolet" seems to be related, and could be some kind of lander software/game, search for a similar named SF project (a small C/console program). (I can't post more interesting links because "you need at least 10 reputation to post more than 2 links" ...)
(By the way, the graphic art in these TM magazines are gorgeous.)
