Journey of Parker Solar Probe

The plot below shows Parker Solar Probe's location and speed (relative to the Sun) as it conducts its science operations. The spacecraft is in a highly elliptical orbit around the Sun (the yellow dot at the center of the plot), reaching its aphelion during the course of the mission initially at Earth and eventually closing to the orbit of Venus. Parker Solar Probe will perform seven Venus flybys in order to more precisely set its trajectory toward the Sun; these flybys will slow the spacecraft down, instead of speeding it up, which is a more common use for planetary flybys.
