RS-25 rocket engine tested

STENNIS SPACE CENTER, Miss. - NASA conducted a full-power, full-duration 650-second RS-25 engine test on the A-1 Test Stand at Stennis Space Center today. Operators fired development engine No. 0525 to a 113 percent thrust level for 60 seconds during the test, the second time they have achieved the highest RS-25 power level. Engineers first fired development engine No. 0528 to that level during a February test at Stennis. Four RS-25 engines will help power NASA's Space Launch System, supplying a combined 2 million pounds of thrust and working in conjunction with a pair of solid rocket boosters to provide more than 8 million pounds of thrust. RS-25 tests at Stennis are conducted by a combined team of NASA, Aerojet Rocketdyne and Syncom Space Services operators. Aerojet Rocketdyne is the RS-25 prime contractor. Syncom Space Services is the prime contractor for Stennis facilities and operations.(Source: NASA, 11/15/18) Previous
