Heat shield took a decade to design & 18 months to build. Made of Reinforced Carbon-Carbon panels - same material that protected Space Shuttles' nose caps & Wing Leading Edges during atmospheric reentry for over 30 years. #ParkerSolarProbe #NASA @ulalaunch #DeltaIVHeavy

There will be 16-mins of round-trip light-time communications delay with Parker as it dives toward the sun and comm blackout periods when it dips behind the sun (as seen from Earth). #ParkerSolarProbe #NASA @ulalaunch #DeltaIVHeavy
