I think there's some interesting things you can do with Venus to help with Earth/Mars trips.

# Orbitally convenient Mars-to-Earth transit times?

(Asked by: username_0 on 2020-01-07)

Are there any peculiar solar system layouts that would result in highly efficient transits between Mars-to-Earth? I am aware of a Hohmann transfer orbit, but can other planets be used to "sling-shot" large quantities of cargo from Mars to Earth in an efficient manner?

If these cannot be answered directly, what would be the best way to go about calculating interesting orbital positions within the next 1000 years?
