Parker Solar Probe Rollback for Launch

On Friday, Aug. 10, 2018, at Cape Canaveral Air Force Station in Florida, the Mobile Service Tower gantry begins to roll back at Space Launch Complex 37, where the United Launch Alliance Delta IV Heavy rocket now stands ready to boost NASA's Parker Solar Probe on a mission to study the Sun. Parker Solar Probe 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.
