The core stage has the same diameter as the shuttle fuel tank and was built in the same factory in east New Orleans.<\/p>\n<p>The huge first stage of NASA\u2019s Saturn 5 moon rocket was also manufactured at Michoud.<\/p>\n<p>Another piece of technology borrowed from the space shuttle for the SLS core stage is its use of RS-25 main engines. Four Aerojet Rocketdyne-built RS-25 engines, each a veteran of multiple space shuttle launches, are affixed to the chrome-colored aft end of the SLS core stage.<\/p>\n<p>Those four engines are upgraded with modernized electronics and rated for slightly higher throttle settings than they were in the shuttle program. The RS-25 engines will be ignited later this year on a test stand at the Stennis Space Center in southern Mississippi during a \u201cgreen run\u201d test series designed to confirm the rocket works as designed when loaded with more than 700,000 gallons of super-cold liquid hydrogen and liquid oxygen propellants.<\/p>\n<p>The four RS-25 engines will power up to full throttle to generate nearly 2 million pounds of thrust during the hotfire test.<\/p>\n<figure id=\"attachment_42766\" aria-describedby=\"caption-attachment-42766\" style=\"width: 1400px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-42766\" src=\"http:\/\/spaceflightnow.com\/wp-content\/uploads\/2020\/01\/IMG_7514-copy.jpg\" alt=\"\" width=\"1400\" height=\"933\" srcset=\"https:\/\/spaceflightnow.com\/wp-content\/uploads\/2020\/01\/IMG_7514-copy.jpg 1400w, https:\/\/spaceflightnow.com\/wp-content\/uploads\/2020\/01\/IMG_7514-copy-300x200.jpg 300w, https:\/\/spaceflightnow.com\/wp-content\/uploads\/2020\/01\/IMG_7514-copy-768x512.jpg 768w, https:\/\/spaceflightnow.com\/wp-content\/uploads\/2020\/01\/IMG_7514-copy-678x452.jpg 678w\" sizes=\"(max-width: 1400px) 100vw, 1400px\"><figcaption id=\"caption-attachment-42766\" class=\"wp-caption-text\">The first SLS core stage emerges from the factory at the Michoud Assembly Facility in New Orleans on Jan. 8, 2020.

A target launch date is still under review after a series of delays have pushed back the SLS\u2019s inaugural test flight from its original schedule in 2017.<\/p>\n<p>The first launch, designated Artemis 1, will carry NASA\u2019s Orion crew capsule on an unpiloted flight into lunar orbit and back to Earth. Boeing teams at Michoud are building a second SLS core stage for the Artemis 2 mission, which could blast off in 2022 or 2023 to carry another Orion vehicle with four astronauts around the moon and back.<\/p>\n<p>The Artemis program\u2019s third mission, planned for 2024, could include an attempt to land astronauts on the moon, a five-year goal set by the Trump administration last year.<\/p>\n<p>Read our earlier story for the details on completion of manufacturing on the SLS core stage.<\/p>\n<p>More photos from Wednesday\u2019s rollout of the SLS core stage in Louisiana are posted below.<\/p>\n<figure id=\"attachment_42767\" aria-describedby=\"caption-attachment-42767\" style=\"width: 1400px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-42767\" src=\"http:\/\/spaceflightnow.com\/wp-content\/uploads\/2020\/01\/IMG_7489-copy.jpg\" alt=\"\" width=\"1400\" height=\"933\" srcset=\"https:\/\/spaceflightnow.com\/wp-content\/uploads\/2020\/01\/IMG_7489-copy.jpg 1400w, https:\/\/spaceflightnow.com\/wp-content\/uploads\/2020\/01\/IMG_7489-copy-300x200.jpg 300w, https:\/\/spaceflightnow.com\/wp-content\/uploads\/2020\/01\/IMG_7489-copy-768x512.jpg 768w, https:\/\/spaceflightnow.com\/wp-content\/uploads\/2020\/01\/IMG_7489-copy-678x452.jpg 678w\" sizes=\"(max-width: 1400px) 100vw, 1400px\"><figcaption id=\"caption-attachment-42767\" class=\"wp-caption-text\">The SLS core stage emerges from the factory in New Orleans.
