On ultimately the most highly inclined, the most concise solar polar trajectory with practically the shortest period

This paper presents the extended orbital synthesis results from the author’s work in 2009 to achieve ballistic and short period out-of-ecliptic trajectories which possess ultimately the most highly and most concise solar polar properties. Those are realized through almost ballistic flight instead of using electric propulsion or solar sail acceleration. The strategy developed utilizes a Jovian gravity assist first, followed by very high speed synchronized multiple polar gravity assists by Earth or Venus. While the author’s work in 2009 presented the trajectories down to almost one year period, this paper will present the further sequences that make the semi-major axis lower than one AU and lower the perihelion distance closer to the Sun for close-up observation of the Sun.
