CommentsFun fact: @NASA spent hundreds of millions of dollars to make reusable shuttle engines disposable for @NASA_SLS. @SpaceX spent their money making one-use engines reusable. Falcon rockets fly (and re-fly) with regularity. SLS has not even gotten off the ground yet. Just sayin' pic.twitter.com/TRKrRT7aGf

Culberson urges NASA contractors to press forward, Houston Chronicle
"[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."
