Delta IV Parker Solar Probe


Delta IV Heavy to Launch Parker Solar Probe

Rocket: Delta IV Heavy
Mission: Parker Solar Probe
Launch Date: No Earlier Than Monday, Aug. 6, 2018
Launch Broadcast: Details to come
Launch Location: Space Launch Complex-37, Cape Canaveral Air Force Station, Florida

Mission Information: Parker Solar Probe is humanity’s first mission to the sun. After launch, it will orbit directly through the solar atmosphere – the corona – closer to the surface than any human-made object has ever gone. While facing brutal heat and radiation, the mission will reveal fundamental science behind what drives the solar wind, the constant outpouring of material from the sun that shapes planetary atmospheres and affects space weather near Earth.

Parker Solar Probe is part of NASA’s Living With a Star Program to explore aspects of the connected sun-Earth system that directly affect life and society.

Launch Notes: Due to the extremely high energy required for this mission, the Delta IV Heavy’s capability will be augmented by a powerful third stage provided by Northrop Grumman Innovation Systems.

Go Delta! Go Parker Solar Probe!


United Launch Alliance’s Delta IV Heavy is the nation’s proven heavy lifter, delivering high-priority mission for the U.S. Air Force, National Reconnaissance Office and NASA. The Delta IV Heavy also launched NASA’s Orion spacecraft on its historic Exploration Flight Test (EFT-1) in 2014.


Space Launch Complex 37

Space Launch Complex 37, the East Coast home of the Delta IV rocket at Cape Canaveral Air Force Station in Florida, is a classic launch pad design with a Fixed Umbilical Tower (FUT) and a Mobile Service Tower (MST). The core stages of the rocket are assembled in the nearby Horizontal Integration Facility, then rolled to the pad for attachment of the payload, final testing and the countdown. The mobile gantry is retracted to unveil the rocket several hours before liftoff.

NASA constructed SLC-37 in the 1960s for uncrewed test flights in the Apollo-Saturn program. The pad was rejuvenated in an extensive overhaul to support the Delta IV starting in the late 1990s. Parker Solar Probe will be the 38th launch from this complex and the 30th by a Delta IV.
