Abstract

On January 2023, NASA's Parker Solar Probe (PSP) mission had completed 14 of its scheduled 24 orbits around the Sun, with the closest approach (i.e., perihelion) of 13.28 solar radii from the Sun's center. PSP's primary science goal is to determine the structure and dynamics of the Sun's coronal magnetic field, understand how the solar corona and wind are heated and accelerated, and determine what processes accelerate energetic particles. The science data returned by PSP led to significant discoveries and potential breakthroughs, yielding more than 700 peer-reviewed publications. The first four years of the prime mission were mainly during the solar cycle minimum. With the rise of solar activity, PSP will explore solar wind variability as the cycle progress to its maximum. I will present an overview of the major scientific discoveries by PSP and the mission's outlook.
