NASA’s Parker Solar Probe Mated to Delta

Encapsulated in its payload fairing, NASA’s Parker Solar Probe is mated to a United Launch Alliance Delta IV Heavy rocket at Cape Canaveral Air Force Station’s Space Launch Complex 37 on Tuesday, July 31, 2018. The Parker Solar Probe is being prepared for a mission to 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.
