Acting NASA Administrator Robert Lightfoot and NASA managers observe construction of the core stage engine sections being built for Space Launch System structural tests and for the first flight of SLS and Orion. The engine section is where the four RS-25 engines will attach to the core stage. SLS construction is back underway in Building 103 in areas not affected by the tornado on Feb. 7, 2017.
