Abstract : The article discusses problems associated with sending Zond 5 and Zond 6 to the moon, as well as the American spaceship Apollo 8. Certain criteria must be met to put the space vehicles on the right course to the moon. Corrections in flight trajectory were successfully made during flights of Zond 5 and Zond 6. The first correction of Zond 5 was made at 325,000 km from earth. The moon's attraction also has considerable effect on the trajectory of flight around the moon. The problem of getting back on course to the earth and then soft landing is considered. The original article has five figures.
