Some before, and many after the accident criticized the use of old engines for the Antares. Many references were made to the long storage time with some mention of them as antiques. The refurbishment of these engines didn’t seem to slow down the slings, arrows and insults much.
My question is, at what point do the old Shuttle engines for the SLS reach the same category as the failed ones on Antares? After all, at the probable flight rate, the used SLS engines will be in the same general age range at some point as the failed ones at Wallops.
Eventually there might be new engines, but how far down the road?
