Analysis of Spacecraft Flight Trajectories to Venus with a Flyby of Asteroids

We have studied energy-low-cost ballistic trajectories of a spacecraft flight to Venus with asteroid flyby. It is shown that when using schemes including a gravitational maneuver required to deliver the lander to a given area on the surface of Venus, the passing of at least one asteroid is possible. A total of 39 asteroids were discovered, whose passage can occur when launching in 2029–2050. An analysis of the attainable landing areas during the flight of a spacecraft to Venus along trajectories of this type has been performed. It is shown that in each launch window in the period from 2029 to 2050, it is possible to find an asteroid whose passage is possible during the time period between two approaches of the spacecraft to Venus.
