Trajectories treated are "swing-around" trajectories, requiring no additional propulsion near observation planet and "orbiting round-trip" trajectories, requiring propulsion to enter into planetocentric orbit and to leave it after specified waiting period; problems are attacked by new simple calculation procedure based on "Lambertian Mechanics" concept; method is adaptable to automatic digital computer.
