SLS and Orion: May 2018 Archives

Contamination found in SLS engine tubing, SpaceNews

"At a May 17 meeting of the Aerospace Safety Advisory Panel (ASAP) at NASA's Kennedy Space Center, panel member Don McErlean said the committee had been briefed on a "late development" with the core stage, being constructed at the Michoud Assembly Facility in New Orleans. A "routine quality assurance inspection" of the core stage, he said, discovered contamination in tubing in the engine section of the core stage, which hosts the vehicle's four RS-25 main engines and associated systems. That contamination turned out to be paraffin wax, which is used to keep the tubes from crimping while being manufactured but is supposed to be cleaned out before shipment."

"[Rep. John] Culberson also queried Orbital ATK on whether the SLS rocket boosters are reusable. Both Elon Musk's SpaceX and Jeff Bezos' Blue Origin are developing reusable rocket components, with Blue Origin's latest test flight occurring Sunday in West Texas. It flew the New Shepard, being designed for space tourism, for its eighth test. Both the spacecraft and booster had flown before. "If Elon Musk and Jeff Bezos are successful in launching rocket bodies and engines four to 10 times, at least, that changes the whole equation," Culberson said. The SLS engines are not designed to be reused, said Brian Duffy, Orbital ATK vice president for NASA Programs."
