The four RS-25 engines for the first launch of NASA’s Space Launch System (SLS) have all arrived at the factory where their Core Stage is being completed. The engines were trucked one by one from Aerojet Rocketdyne’s final assembly facility at the Stennis Space Center in Mississippi to the Michoud Assembly Facility (MAF) in New Orleans, with the last engine arriving on June 27.
The engines are now back together next door to the final assembly area at MAF, where the elements of Core Stage-1 are being put together. Core Stage-1 is the first flight article in the SLS Program, and before the engines can be installed, prime contractor Boeing is working to finish functional testing of the engine section/boattail and then attach it to the rest of the stage.
Four of the five major stage elements were recently joined and outfitting of that section of the stage continues in parallel with testing and checkout of the engine section. NASA and Boeing are still targeting completion of the stage in December.
