That is one mega Moon rocket 🤩 The Artemis I Space Launch System rocket is seen atop the mobile launcher inside High Bay 3 of the Vehicle Assembly Building at NASAKennedy Space Center in Florida on Sept. 20, 2021. All 10 levels of work platforms were extended and retracted as part of an umbilical test. Next month, NASA will conduct a “wet dress rehearsal” in which the fully stacked rocket will be rolled out to the launch pad for a simulation that includes launch control at Kennedy, Mission Control at NASAJohnson Space Center, and a full operational checkout and countdown to launch. The simulation includes loading the large, central core stage of the rocket with liquid oxygen and liquid hydrogen – that’s the “wet” part. Following a successful wet dress rehearsal, NASA will set a specific launch date for the Artemis I mission. Credit: NASA/Frank Michaux #MegaMoonRocket #Rocket #MoonRocket #SLS #Launch
