The NASA, Aerojet Rocketdyne, and Syncom Space Services team at Stennis Space Center in Mississippi have conducted a “make-up” hot-fire test of a development RS-25 engine (E0528) on Friday. The test was deemed to be for the full duration of 650 seconds, as required, following problems with the A-1 test stand facility that resulted in a mid-July test being cut short.
