With NASA’s boldest program since Apollo to return humans to the Moon, NASA is constructing the world’s most power rocket – the Space Launch System (SLS) – to bring personnel and materiel support to cislunar orbit and the surface below. SLS core engine stage testing is underway at the Stennis Space Center and this event will focus on the importance of this new space launch capability and will highlight the vision and workforce behind the design, manufacturing, and assembly of this massive vehicle.
