The engine is one of four new RS-25s that will help power the core stage of the heavy-lift exploration rocket during the Artemis V mission. The first four Artemis missions are launching on SLS rockets equipped with repurposed engines from NASA\u2019s Space Shuttle Program.<\/p>\n<p>\u201cThis milestone marks the newly built RS-25 engine\u2019s transition from a development program to a production program,\u201d said <strong>Mike Lauer, RS-25 program director, Aerojet Rocketdyne, L3Harris<\/strong>. \u201cBeginning with Artemis V, the SLS core stage will be powered by brand new engines built using modern techniques that have reduced production costs while maintaining the engine\u2019s legendary reliability and performance.\u201d<\/p>\n<p>The next step for E20001 is acceptance testing, where the engine will undergo a static hot-fire test on the Fred Haise Test Stand (formerly A-1 Test Stand) at NASA Stennis for 500 seconds to demonstrate the performance characteristics required for SLS missions. During the test, the engine will run at full thrust \u2013 111 percent of the shuttle engine\u2019s rated thrust \u2013 dip down to 80 percent, and then throttle back up.<\/p>\n<div class=\"widget-layout related-content-also-read-box my-3\">\n<h4 class=\"mb-0\">Also Read: NASA&#8217;s Artemis Space Mission<\/h4>\n<\/div>\n<p>\u201cWe take a \u2018test like you fly\u2019 approach when validating engine performance, and this test is roughly representative of the RS-25\u2019s in-flight operating profile,\u201d added Lauer. \u201cDuring actual missions, for example, the SLS core stage engines throttle back briefly when the vehicle\u2019s solid rocket boosters are jettisoned.\u201d<\/p>\n<p>The new RS-25 engines for Artemis V and beyond feature 3D-printed parts and major structural components that were redesigned to take advantage of modern manufacturing techniques to reduce cost and lead time. For example, the main combustion chamber, nozzle, and powerhead \u2013 the latter serving as the structural backbone of the engine \u2013 have fewer parts, significantly reducing the number of steps, including welds, required for assembly.<\/p>\n<p>\u201cWe\u2019ve maintained all of the flow passages and performance aspects of earlier RS-25 engines, but modernized the way we build different components,\u201d continued Lauer. \u201cThe team is currently assembling the three remaining Artemis V engines, and as production gathers momentum, we expect to incorporate lessons learned to further boost production efficiency.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Preparations are underway for NASA\u2019s Artemis V mission, with the first RS-25 engine for the SLS (Space Launch System) rocket now fully assembled at NASA\u2019s Stennis Space Center in Mississippi.
