|Abstract||A mission to the sun originally called Solar Probe was first considered in 1958 and stayed in concept and feasibility studies for five decades until 2007, when a new mission design was created that changed the original mission architecture. The re-designed mission was named Solar Probe Plus due to significant advantages in technical implementation and science return, and it was renamed Parker Solar Probe (PSP) in 2017. PSP was launched on August 12, 2018 as the first mission to touch the Sun. This paper presents an overview of the mission design changes over the mission development phase and the final PSP mission design, including the launch, launch targets, and full set of mission trajectories over the 24-day 2018 launch period. Core to the PSP mission design is a unique V7GA mission trajectory that uses 7 Venus gravity-assists to spiral down to the Sun, as close as 9.86 solar radii from the Sun’s center, and offers 24 solar encounters in 7 years of the mission by visiting the Sun 3 to 4 times per year.|
