RS-25 tested at open house

STENNIS SPACE CENTER, Miss. – More than 1,500 people watched a verification test of an RS-25 rocket engine during an open house at NASA’s Stennis Space Center in South Mississippi Thursday. The engine that was tested, engine E2063, is one of the engines that will power the Space Launch System (SLS). The test was 500 seconds, the same duration the engine will power during an actual launch. Engine E2063 is scheduled for use on NASA’s second mission of SLS and Orion, known as Exploration Mission-2 (EM-2). The first integrated flight test of SLS and Orion, Exploration Mission-1 (EM-1), will be an uncrewed final test of the rocket and its systems. The EM-2 flight will be the first to carry astronauts aboard the Orion spacecraft. (Source: NASA, 10/19/17) Previous
