SLS is a key component of <a href=\"https:\/\/www.theverge.com\/2022\/3\/17\/22978972\/nasa-sls-monster-rocket-roll-out-florida-history\">NASA\u2019s Artemis program<\/a>, which aims to send humans back to the Moon by 2025. The massive rocket will carry the Orion crew capsule, which aims to carry its first astronauts in 2024. <\/p>\n<div class=\"c-float-right\">\n<aside id=\"nNzJxu\"><q>NASA determined it could not successfully launch<\/q><\/aside>\n<\/div>\n<p id=\"xtAkGf\">\u201cLaunch controllers were continuing to evaluate why a bleed test to get the RS-25 engines on the bottom of the core stage to the proper temperature range for liftoff was not successful, and ran out of time in the two-hour launch window,\u201d the agency said in <a href=\"https:\/\/blogs.nasa.gov\/artemis\/2022\/08\/29\/launch-attempt-scrubbed\/\">a blog post<\/a>. <\/p>\n<p id=\"jZWTro\"><a href=\"https:\/\/www.theverge.com\/23321544\/nasa-artemis-sls-orion-explained\">The SLS was set to take off<\/a> at approximately 8:33AM ET but was scrubbed after NASA determined it could not successfully launch. NASA scientists determined that engine number three could not reach the appropriate temperature range to allow for a launch. The rocket remains in \u201cstable, safe condition,\u201d the agency said. <\/p>\n<p id=\"fonJ36\"><a href=\"https:\/\/blogs.nasa.gov\/artemis\/2022\/08\/29\/engineers-troubleshooting-engine-conditioning-issue\/\">NASA first reported<\/a> the engine issue at 6:33AM ET:<\/p>\n<blockquote readability=\"10\">\n<p id=\"vmZmyH\">While liquid oxygen loading into the interim cryogenic propulsion stage continues and core stage tanks continue to be replenished with propellants, engineers are troubleshooting an issue conditioning one of the RS-25 engines (engine 3) on the bottom of the core stage. Launch controllers condition the engines by increasing pressure on the core stage tanks to bleed some of the cryogenic propellant to the engines to get them to the proper temperature range to start them. Engine 3 is not properly being conditioned through the bleed process, and engineers are troubleshooting.<\/p>\n<\/blockquote>\n<p id=\"25TxQT\">The next attempt is scheduled for Friday, September 2nd, at approximately 12:48PM ET. If that launch is successful, the mission will last 39 days, with Orion splashing down in the ocean on October 11th. If it doesn\u2019t launch then, a third launch window will open on Monday, September 5th. <\/p>\n<figure class=\"e-image\">\n  <span class=\"e-image__inner\"><\/p>\n<p>    <span class=\"e-image__image \" data-original=\"https:\/\/cdn.vox-cdn.com\/uploads\/chorus_asset\/file\/23978271\/Screen_Shot_2022_08_29_at_8.21.12_AM.png\"><\/p>\n<picture class=\"c-picture\" data-cid=\"site\/picture_element-1661783704_6671_1249181\" data-cdata='{\"asset_id\":23978271,\"ratio\":\"*\"}'><source srcset=\"https:\/\/cdn.vox-cdn.com\/thumbor\/1KI-3QKXd9qz-F7X3lQuRDmN0es=\/0x0:2880x1622\/320x0\/filters:focal(0x0:2880x1622):format(webp):no_upscale()\/cdn.vox-cdn.com\/uploads\/chorus_asset\/file\/23978271\/Screen_Shot_2022_08_29_at_8.21.12_AM.png 320w, https:\/\/cdn.vox-cdn.com\/thumbor\/J7o1sosbeI_KTIGRxMbh2qNnws8=\/0x0:2880x1622\/520x0\/filters:focal(0x0:2880x1622):format(webp):no_upscale()\/cdn.vox-cdn.com\/uploads\/chorus_asset\/file\/23978271\/Screen_Shot_2022_08_29_at_8.21.12_AM.png 520w, https:\/\/cdn.vox-cdn.com\/thumbor\/I1HHfI-qWd7v1RzpULPX3WNs-xw=\/0x0:2880x1622\/720x0\/filters:focal(0x0:2880x1622):format(webp):no_upscale()\/cdn.vox-cdn.com\/uploads\/chorus_asset\/file\/23978271\/Screen_Shot_2022_08_29_at_8.21.12_AM.png 720w, https:\/\/cdn.vox-cdn.com\/thumbor\/wvl9da1P-XMPyfUneEXoehrgEEc=\/0x0:2880x1622\/920x0\/filters:focal(0x0:2880x1622):format(webp):no_upscale()\/cdn.vox-cdn.com\/uploads\/chorus_asset\/file\/23978271\/Screen_Shot_2022_08_29_at_8.21.12_AM.png 920w, https:\/\/cdn.vox-cdn.com\/thumbor\/MWjGC1WbdaV_UBrmLjr0pKtPNf8=\/0x0:2880x1622\/1120x0\/filters:focal(0x0:2880x1622):format(webp):no_upscale()\/cdn.vox-cdn.com\/uploads\/chorus_asset\/file\/23978271\/Screen_Shot_2022_08_29_at_8.21.12_AM.png 1120w, https:\/\/cdn.vox-cdn.com\/thumbor\/qBT8asce8o4zMfWlk0-msNCkLQc=\/0x0:2880x1622\/1320x0\/filters:focal(0x0:2880x1622):format(webp):no_upscale()\/cdn.vox-cdn.com\/uploads\/chorus_asset\/file\/23978271\/Screen_Shot_2022_08_29_at_8.21.12_AM.png 1320w, https:\/\/cdn.vox-cdn.com\/thumbor\/7lA3r0804bJFLS3fjQkSZ86o5c8=\/0x0:2880x1622\/1520x0\/filters:focal(0x0:2880x1622):format(webp):no_upscale()\/cdn.vox-cdn.com\/uploads\/chorus_asset\/file\/23978271\/Screen_Shot_2022_08_29_at_8.21.12_AM.png 1520w, https:\/\/cdn.vox-cdn.com\/thumbor\/EVsT_EDEL8Fk2m1FBBiBj4mssrA=\/0x0:2880x1622\/1720x0\/filters:focal(0x0:2880x1622):format(webp):no_upscale()\/cdn.vox-cdn.com\/uploads\/chorus_asset\/file\/23978271\/Screen_Shot_2022_08_29_at_8.21.12_AM.png 1720w, https:\/\/cdn.vox-cdn.com\/thumbor\/XeSXNMbX-GKFUDWm7fWaBgD8tFU=\/0x0:2880x1622\/1920x0\/filters:focal(0x0:2880x1622):format(webp):no_upscale()\/cdn.vox-cdn.com\/uploads\/chorus_asset\/file\/23978271\/Screen_Shot_2022_08_29_at_8.21.12_AM.png 1920w\" sizes=\"(min-width: 1221px) 846px, (min-width: 880px) calc(100vw -

It\u2019s unclear what that means for the rocket before the agency attempts the next launch. <\/p>\n<p id=\"bEHhI7\">If all three launch dates prove unsuccessful, NASA will face an undesirable situation. Teams must fully test the flight termination system, which is used to destroy the rocket if something goes catastrophically wrong during the launch, before launch, and that work can only be done inside the Vehicle Assembly Building (VAB) at NASA\u2019s Kennedy Space Center. <\/p>\n<div class=\"c-float-right\">\n<aside id=\"y7Fxn0\"><q>If all three launch dates prove unsuccessful, NASA will face an undesirable situation<\/q><\/aside>\n<\/div>\n<p id=\"i2tQgl\">Once the SLS is rolled out from the VAB, there is a 20-day time limit for the flight termination system before it has to be tested again. That means the rocket has to launch within 20 days of its rollout, or it must be returned to the VAB so that the flight termination system can get checked out again. That testing takes time, so if SLS is forced to come back to the VAB after rolling out in August, chances are it wouldn\u2019t be ready to fly until late October. <\/p>\n<p id=\"MiRWGw\">When and if NASA is able to successfully launch, the next noteworthy flight is set for 2024, when the agency has said it will send a crew of astronauts around the Moon and back without landing. Then, in 2025, NASA plans to launch the first crewed Moon landings since the Apollo 17 mission in 1972. This landing will include the first woman to walk on the Moon. <\/p>\n<p id=\"1FlrTH\">One of the main goals of this flight is testing Orion\u2019s heat shield, which will have to endure temperatures of 2,800 degrees Celsius as it enters Earth\u2019s atmosphere.<\/p>\n<\/div>\n<p><code><br \/><\/br><\/code><\/p>\n<p>Source: <a href=\"https:\/\/www.theverge.com\/2022\/8\/29\/23326681\/nasa-artemis-sls-orion-rocket-moon-first-launch-delay-engine\">https:\/\/www.theverge.com\/2022\/8\/29\/23326681\/nasa-artemis-sls-orion-rocket-moon-first-launch-delay-engine<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Source: NASA delayed the launch of its colossal next-generation Space Launch System (SLS) rocket, as an engine bleed issue forced the agency to scrub its plans.
