View of the NASA rocket factory floor, taken from a scissor lift
<ul><li>The Space Launch System intertank, shown here moving down the factory floor, finished structural assembly at NASA’s Michoud Assembly Facility in New Orleans. Technicians moved it to an area where it will be coated with a thermal protection system. The yellow object, left back, is the engine section of the core stage, which also completed structural assembly and is being outfitted with propulsion system hardware that will feed fuel to the four RS-25 engines on the first SLS mission.</li></ul>
