A United Launch Alliance Delta IV Heavy common booster core arrives at the Horizontal Integration Facility at Cape Canaveral Air Force Station for preflight processing. The Delta IV Heavy will launch NASA's upcoming Parker Solar Probe mission. 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. Liftoff atop the Delta IV Heavy rocket is scheduled to take place from Cape Canaveral's Space Launch Complex 37 in summer 2018.

Inside the United Launch Alliance (ULA) Horizontal Integration Facility at Cape Canaveral Air Force Station in Florida, the Interim Cryogenic Propulsion Stage (ICPS) for NASA's Space Launch System rocket was removed from its shipping container and then lowered and secured onto a movable transport stand. The ICPS is the first integrated piece of flight hardware to arrive for the SLS. The ICPS arrived from the ULA facility in Decatur, Alabama. The ICPS is the in-space stage that is located toward the top of the rocket, between the Launch Vehicle Stage Adapter and the Orion Spacecraft Adapter. It will provide some of the in-space propulsion during Orion's first flight test atop the SLS on Exploration Mission 1.

A United Launch Alliance Delta IV Heavy second stage, packaged in its shipping container, arrives at the Horizontal Integration Facility at Cape Canaveral Air Force Station for preflight processing.
