Parker solar probe is on the journey

Magnetic switchbacks was a surprise from solar wind and they don’t know the cause.
Earth view smooth solar wind, sun view dynamic system.
Interesting the probes picture of solar wind looks like wind tunnel or an eye depending on tunnel vision or wide angling.

The Parker Solar Probe mission design uses repeated gravity assists at Venus to incrementally decrease its orbital perihelion to achieve a final altitude (above the surface) of approximately 8.5 solar radii, or about 6×106 km (3.7×106 mi; 0.040 AU).[30] The spacecraft trajectory will include seven Venus flybys over nearly seven years to gradually shrink its elliptical orbit around the Sun, for a total of 24 orbits.[1] The near Sun radiation environment is predicted to cause spacecraft charging effects, radiation damage in materials and electronics, and communication interruptions, so the orbit will be highly elliptical with short times spent near the Sun.[29]
