The NASA Parker Solar Probe mission is a mission designed to help humanity better understand the Sun, where changing conditions can propagate out into the solar system, affecting Earth and other worlds. As such, the primary goals are to examine the acceleration of solar wind through the movement of heat and energy in the Sun’s corona in addition to study solar energetic particles.

The probe was launched on Delta IV on Aug. 12, 2018, and faces temperatures that reach approximately 2,500 F (1,377 C). Goddard Space Flight Center’s Living with a Star Program flight program encapsulates the Parker Solar Probe.
