‘Taking Flight’ (nearly). Our beautiful Artemis III Space Launch System (SLS) Core Stage left the surface of the earth (briefly) today as it ‘flew over the hump’ via a giant crane in the Vehicle Assembly Building to be mated between our 2 already assembled Solid Rocket Boosters on the Mobile Launcher. Spectacular job by our SLS, Exploration Ground Systems,and @NASAKennedy team! Go @NASAArtemis III!
