The launch of a ULA #DeltaIVHeavy rocket carrying the #NROL68 mission for the @NatReconOfc has been delayed. During routine pre-launch processing the team discovered a flight valve that exhibited off-nominal behavior. A new launch date will be confirmed when available.

🥺 PENÚLTIMO DELTA IV HEAVY 🚀

▫️El 20 de Abril está previsto el lanzamiento del penúltimo #DeltaIVHeavy de @ulalaunch

▫️La misión #NROL68 pondrá en órbita un satélite de reconocimiento de Estados Unidos 🇺🇸

▫️Podría coincidir con el primer intento orbital de la #Starship 🙌

A #photograph of a #UnitedLaunchAlliance #ULA #DeltaIVHeavy #rocket at #CapeCanaveral’s LC-37B.
The #Delta IV #Heavy is a variant of the Delta IV with 3 #CommonBoosterCores #CBC’s mounted side-by-side with the #DeltaCryogenicSpperStage #DCSS mounted on the center CBC. The center CBC throttles its #Rocketdyne RS-68 #engine down to 55% rated #thrust while the “outboard” CBC’s remain at 100% until #burnout.
The center CBC then throttles up until it burns its fuel, then releases the DCSS and #spacecraft.

My #ULA #DeltaIV Heavy rocket model is complete. The #DeltaiVHeavy is my favorite rocket ever. I am so happy to have this big model of the rocket in my collection.

Décollage ce dimanche matin depuis #CapCanaveral en #Floride de la fusée #DeltaIVHeavy🚀 emportant la sonde #ParkerSolarProbe🛰️ en orbite héliocentrique. Et en présence d'#EugèneParker qui, à 91 ans, a tenu à y assister par deux fois alors que le lancement était programmé pour 03:30 heure locale. #kudos
