Parker Solar Probe: A Mission to Touch the Sun
Dr. Jim Kinnison, PSP Mission System Engineer, The Johns Hopkins University Applied
Physics Laboratory

Sixty years in preparation, Parker Solar Probe launched on August 12, 2018 and a short three months later, reached the innermost regions of the heliosphere to sample the Sun’s corona at 0.17 AU. Traveling through a region of space never before explored, this innovative mission must  survive solar illumination about 450 times that seen in Earth orbit, an energetic and dynamic solar plasma, and hypervelocity dust impacts at speeds up to 300 km/s. Parker Solar Probe will continue deeper into the corona over the next seven years to make in situ measurements of the Sun’s corona and solar wind to push the boundaries of our understanding of the Sun and its effect on the Earth. Jim will discuss the science of Parker Solar Probe, the engineering that allows the spacecraft to survive this extreme environment, and the first results from the mission.

Throughout his career, Jim Kinnison has focused on the intersection of space systems engineering and the practical aspects of surviving extreme environments. Beginning in 1987 at The Johns Hopkins University Applied Physics Laboratory, Jim became a leader in space radiation effects, working on a number of spacecraft such as MESSENGER, NEAR, and New Horizons to develop robust systems to accomplish cutting edge science. In 2007, while completing his PhD from Clemson University, he began an 11-year journey leading the Parker Solar Probe technical team as Mission System Engineer from initial concept, through design and build of the spacecraft, to launch and early operations.
