Parker Solar Probe Solar Array Deployment

NASA's Parker Solar Probe solar arrays are deployed for testing at the Astrotech processing facility in Titusville, Florida, near NASA's Kennedy Space Center on Sunday, June 3, 2018. The Parker Solar Probe will launch on a United Launch Alliance Delta IV Heavy rocket from Space Launch Complex 37 at Cape Canaveral Air Force Station in Florida no earlier than Aug. 4, 2018. The mission will perform the closest-ever observations of a star when it travels through the Sun's atmosphere, called the corona. The probe will rely on measurements and imaging to revolutionize our understanding of the corona and the Sun-Earth connection.
