Space Launch System (SLS) relies on four RS-25 engines (and two solid rocket boosters) to leave the planet for destinations like the Moon and beyond as part of NASA\u2019s Artemis program.<\/p>\n<p><span id=\"more-17087\"><\/span><\/p>\n<p class=\"wp-block-paragraph\">This is the sixth of seven planned RS-25 hot fire tests being conducted at Stennis Space Center.<\/p>\n<p class=\"wp-block-paragraph\">During the test, NASA fires off the RS-25 engine for 500 seconds (over 8 minutes) to match the duration of firing during an SLS launch. These tests are conducted with NASA\u2019s A-1 Test Stand.<\/p>\n<p class=\"wp-block-paragraph\">This particular test also validates a new manufacturing process for RS-25 engine components, as NASA explains:<\/p>\n<p>\t<span class=\"outbrain-ad-label\"><\/span><\/p>\n<p>\t\t<script type=\"text\/plain\">\n\t\t\twindow.adSlotsConfig = window.adSlotsConfig || [];<\/p>\n<p>\t\t\tadSlotsConfig.push( {\n\t\t\t\tslotID: '\/1049447\/Outbrain',\n\t\t\t\tslotName: 'div-gpt-ad-outbrain-ad-17087',\n\t\t\t\tsizes: [300, 250],\n\t\t\t\tslotPosition: 'mid_article'\n\t\t\t} );\n\t\t<\/script><\/p>\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p>Along with providing performance data to Aerojet Rocketdyne, lead contractor for the SLS engines, the Aug. 5 test enabled the team to evaluate new engine components manufactured with cutting-edge and cost-saving technologies, eliminate operating risks, and enhance engine production. <\/p>\n<p>In addition to operating the engine at 109% of its original power level for extended periods during the hot fire, NASA verified new manufacturing processes while evaluating the performance of the engine\u2019s low-pressure fuel turbopump. The pump significantly boosts the pressure of liquid hydrogen delivered to the high-pressure fuel turbopump to help prevent cavitating, the forming of \u201cbubbles\u201d or \u201cvoids\u201d, which can collapse or cause shock waves that may damage machinery.<\/p>\n<\/blockquote>\n<p class=\"wp-block-paragraph\">Watch the footage captured from the RS-25 hot fire test:<\/p>\n<figure class=\"wp-block-embed alignwide is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\">\n<iframe loading=\"lazy\" id=\"post-youtube-video-1\" class=\"youtube-player\" width=\"640\" height=\"360\" data-src=\"https:\/\/www.youtube.com\/embed\/-bmVbIlOc8k?version=3&amp;rel=0&amp;showsearch=0&amp;showinfo=1&amp;iv_load_policy=1&amp;fs=1&amp;hl=en-US&amp;autohide=2&amp;start=312&amp;wmode=transparent&amp;enablejsapi=1\" allowfullscreen=\"true\" style=\"border:0;\" sandbox=\"allow-scripts allow-same-origin allow-popups allow-presentation allow-popups-to-escape-sandbox\" src=\"https:\/\/www.youtube.com\/embed\/-bmVbIlOc8k?version=3&amp;rel=0&amp;showsearch=0&amp;showinfo=1&amp;iv_load_policy=1&amp;fs=1&amp;hl=en-US&amp;autohide=2&amp;start=312&amp;wmode=transparent&amp;enablejsapi=1\" title=\"NASA Stennis Live Stream\"><\/iframe><br \/>\n<\/figure>\n<p class=\"wp-block-paragraph\">Four of these RS-25 engines will be used to power NASA\u2019s SLS rocket.
