RS-25 hot fire opens 2018 testing for SLS engines
The RS-25 test team conducted their first hot-fire test of the year in the A-1 test stand at the Stennis Space Center in Mississippi. The Tuesday afternoon test continued development work started with Development Engine 0528 (E0528) in last month’s hot-fire. The six-minute long firing put the new, “3D printed” pogo accumulator assembly through a…
