You may be thinking “This launch pad looks familiar!” That’s because SLC-41 has been modified to support both #VulcanRocket and #AtlasV.

RT @ulalaunch
While it looks like the #AtlasV Mobile Launch Platform, the Vulcan Launch Platform (VLP) is built to accommodate #VulcanCentaur's much larger diameter and its use of liquefied natural gas as propellant. It stands 183 feet tall and weighs 1.3 million pounds!

❤️ SLC-41, we 🫶 you ❤️

Love,
#VulcanRocket & #AtlasV

RT @ulalaunch
#VulcanRocket combines the best of today's #AtlasV and #DeltaIVHeavy with the latest technology advancements to produce a single launch system that provides higher performance and greater affordability while continuing to deliver ULA's unmatched reliability and precision.

Eyes to the skies, California early birds! If you spot #JPSS2/#LOFTID aboard their #AtlasV rocket, share photos and videos so we can see. Liftoff is now expected 1:49am PT (4:49am ET, 0949 UTC). nasa.gov/live twitter.com/ulalaunch/stat… https://twitter.com/NASA/status/1590639797491879936

Also hitching a ride aboard this @ulalaunch #AtlasV is LOFTID – an innovative reentry vehicle. Once in low-Earth orbit, LOFTID's aeroshell or heat shield will inflate and descend back to Earth to demo how this tech can slow down a spacecraft for reentry: go.nasa.gov/3Co4IRN twitter.com/NASA_LSP/statu… pic.twitter.com/MIeZuRrMLT https://twitter.com/NASA_Technology/status/1575880428036112384

#ICYMI @ulalaunch unveiled its #AtlasV rocket art, which was hand-painted due to the fairing's ribbed surface. A payload on the upcoming #JPSS2 satellite mission, #LOFTID will demonstrate an inflatable heat shield for atmospheric re-entry.

We have indication of @ULALaunch #AtlasV Centaur Main Engine Cutoff 2 (MECO2). The #LucyMission Centaur and Spacecraft will now coast for approximately 11 minutes before spacecraft separation.

RT from NASA's Launch Services Program (@NASA_LSP)

We have indication of @ULALaunch #AtlasV Centaur Second Main Engine Start (MES2). This will be an ~ 6 minute burn. #LucyMission

RT from NASA's Launch Services Program (@NASA_LSP)

We have indication of Centaur First Main Engine Cutoff (MECO1). The @ULALaunch #AtlasV Centaur will now be in an approximately 27 minute coast before a second and final Centaur burn. #LucyMission

RT from NASA's Launch Services Program (@NASA_LSP)

We have indication of #LucyMission @ULALaunch #AtlasV Booster Engine Cutoff (BECO), Core Booster Separation, Centaur First Main Engine Start (MES1) and Payload Fairing Jettison! This will be an ~ 9 minute burn.

RT from ULA (@ulalaunch)

Wondering if you will see the #AtlasV near you? Our visibility graphic shows when the rocket will rise into view.

RT from ULA (@ulalaunch)

We are counting down to today's launch at 11:12amPDT (2:12pmEDT; 1812 UTC), and all systems are "go" here at #Vandenberg's Remote Launch Control Center and the pad. The #AtlasV guidance system test has started, the next major milestone in the count. http://bit.ly/av_landsat9

RT from Boeing Space (@BoeingSpace)

This morning, after the @ulalaunch team completes #AtlasV operations our teams will roll the rocket and #Starliner back to the Vertical Integration Facility for inspection and testing to inform next steps for our OFT-2 mission.

More updates as information becomes available.
