Taking the two body problem as the model to explore Mars from the earth, it is necessary to seek an unpowered Venus transit force on the way to find the optimal time window and time of flight (the minimum total velocity increment), and draw the contour map of the Pork-Chop emission energy of the earth to Venus. The total launch time window is from 2023 to 2033, and the total flight time is not more than 2 years.
