land the first woman, first person of color, and first international partner astronaut on the lunar surface; and prepare for human expeditions to Mars for the benefit of all.<\/p>\n\n\n\n<p>Contributing to that effort, the NASA Stennis test team conducted a full-duration, 500-second hot fire to complete the 12-test series on developmental engine E0525, providing critical performance data for the final RS-25 design certification review. The April 3 hot fire completed a test series that began in October 2023.<\/p>\n\n\n\n<p>RS-25 engines are evolved space shuttle main engines, upgraded with new components to produce the additional power needed to help launch NASA\u2019s SLS rocket. The first four Artemis missions are using modified space shuttle main engines also tested at NASA Stennis. For each Artemis mission, four RS-25 engines, along with a pair of solid rocket boosters, power the SLS rocket, producing more than 8.8 million pounds of total combined thrust at liftoff.<\/p>\n\n\n\n<p>\u201cThis was a critical test series, and credit goes to the entire test team for their dedication and unique skills that allowed us to meet the schedule and provide the needed performance data,\u201d said Chip Ellis, project manager for RS-25 testing at NASA Stennis. \u201cThe tests conducted at NASA Stennis help ensure the safety of our astronauts and their future mission success. We are proud to be part of the Artemis mission.\u201d<\/p>\n\n\n\n<p>The E0525 developmental engine featured new key components \u2013 including a nozzle, hydraulic actuators, flex ducts, and turbopumps \u2013 that matched design features of those used during an initial certification test series completed at NASA Stennis last summer.<\/p>\n\n\n\n<p>The two certification test series helped verify the new engine components meet all Artemis flight requirements moving forward. Aerojet Rocketdyne is using techniques such as 3D printing to produce new RS-25 engines more efficiently, while maintaining high performance and reliability. NASA has awarded the company contracts to provide 24 new engines, supporting SLS launches for Artemis V through Artemis IX.<\/p>\n\n\n\n<p>\u201cSuccessfully completing this rigorous test series is a testament to the outstanding work done by the team to design, implement and test this upgraded version of the RS-25 that reduces the cost by 30% from the space shuttle program,\u201d said Mike Lauer, RS-25 program director at Aerojet Rocketdyne. \u201cWe tested the new RS-25 engines to the extreme limits of operation to ensure the engines can operate at a higher power level needed for SLS and complete the mission with margin.\u201d<\/p>\n\n\n<div id=\"\" class=\"nasa-gb-align-center nasa-button-link padding-y-1 padding-x-0 hds-module wp-block-nasa-blocks-related-link\">\n\t<a href=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2024\/04\/s24-016-rs-25-certification-series-sidebar.pdf?emrc=2cf871\" target=\"_self\" class=\"button-primary button-primary-md link-external-true\" aria-label=\"RS-25 Final Certification Test Series by the Numbers\">\n\t\t<span class=\"line-height-alt-1\">RS-25 Final Certification Test Series by the Numbers<\/span>\n\t\t<svg viewBox=\"0 0 32 32\" fill=\"none\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\"><circle class=\"button-primary-circle\" cx=\"16\" cy=\"16\" r=\"16\"><\/circle><path d=\"M8 16.956h12.604l-3.844 4.106 1.252 1.338L24 16l-5.988-6.4-1.252 1.338 3.844 4.106H8v1.912z\" class=\"color-spacesuit-white\"><\/path><\/svg>\n\t<\/a>\n\n\t<\/div>\n\n\n<p>All RS-25 engines are tested and proven flightworthy at NASA Stennis prior to use on Artemis missions.
