Professor Joe Giacalone, Co-Investigator for the Integrated Science Investigation of the Sun (IS☉IS) instrument on Parker Solar Probe. The Parker Solar Probe will swoop to within 4 million miles of the sun's surface, facing heat and radiation like no spacecraft before it. Launching in 2018, Parker Solar Probe will provide new data on solar activity and make critical contributions to our ability to forecast major space-weather events that impact life on Earth.
