I'm out of town, but the final launch of the #ULA Delta IV Heavy is targeting 2:45 PM EDT, from #CCSFS Launch Complex 37. The ULA webcast should start on YouTube around 1:15 PM EDT.
After this launch, #SpaceX is looking at LC-37 for future #Starship launches, so this is the last time you'll ever see a launch from LC-37 in its current configuration.
