So, we\u2019re really looking at the protection of the [zero] deck, to protect the mobile launcher and improve our imagery,\u201d said Sumner.<\/p>\n<p>The blast plates on the ML deck will also be replaced and the supports around them will be strengthened. \u201cThey\u2019re basically on the perimeter of the flame hole, and that\u2019s where we see the most blast pressures. And they\u2019re basically partly there to protect the [zero] deck structure and take the majority of that blast.\u201d<\/p>\n<p>\u201cWe did take some damage, they did warp some, so we had to go [with] new [plates],\u201d Sumner continued. \u201cThere\u2019s also what we call water dams, and it\u2019s basically plates that when the ignition overpressure flows, that it redirects some of the flow, again for imagery and to keep the water from going directly into the vehicle. We\u2019re reinstalling new plates, the water dams below, and we\u2019re also looking at adding upper water dams. And again, that is for imagery improvement.\u201d<\/p>\n<p>\u201cBest case we will be able to use these through Artemis II and Artemis III,\u201d Sumner explained. \u201cWorst case, they\u2019re sacrificial and the blast plates will have to be replaced again after Artemis II, so we\u2019ll have to see how that goes. But I do know they\u2019re trying to make some improvements based on what we saw during Artemis I.\u201d<\/p>\n<p><img fetchpriority=\"high\" decoding=\"async\" class=\"alignnone\" src=\"https:\/\/cdn.discordapp.com\/attachments\/1136391497537835059\/1138941645618958376\/L2_Membership_ShopBanner.png\" alt=\"\" width=\"2160\" height=\"720\">\u201cThose changes may include change in thickness, strength, and some other structural reinforcements that they are adding.\u201d<\/p>\n<p>The damage to the blast plates did not come as a surprise, and according to Sumner, \u201cI would say there was some risk known there that those [blast plates] may be sacrificial or that the warping may happen.\u201d<\/p>\n<p>\u201cSo we did know, we were prepared to refabricate those if needed, and it was needed. So we\u2019ve went right into that and those are being replaced right now and we\u2019re replacing those out at the pad. Schedule wise we\u2019re in good shape with the replacement of those,\u201d he added. \u201cThe teams are preparing for the first IOP flow test out at the pad here in the next few weeks. \u201d<\/p>\n<\/p>\n<p><iframe title=\"NASA Sound Suppression Water test for SLS Mobile Launcher - 12 Oct. 2019\" src=\"https:\/\/www.youtube.com\/embed\/wqhCP48XXP0?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" allowfullscreen=\"\" name=\"fitvid0\" data-gtm-yt-inspected-14=\"true\" data-gtm-yt-inspected-21=\"true\"><\/iframe><\/p>\n<p>Repairs on the ML<\/p>\n<p>It was previously noted in an earlier interview that modifications to improve the liquid hydrogen systems on the ML in response to issues faced during the various Wet Dress Rehearsals and launch counts could be required. \u201cWe have not done any major modification on liquid hydrogen,\u201d said Sumner.<\/p>\n<p>\u201cWe\u2019ve repaired anything that was damaged during launch and brought them back to what we had before. I know there were some lessons learned out of the Artemis I wet dress. I would say on the operation side of the house, they\u2019re working to correct those lessons learned.\u201d<\/p>\n<p>However, additional work is occurring to harden the Gaseous Nitrogen, GN2, system on the ML to avoid the challenges experienced during Artemis I. \u201cWe definitely looked into that one because that affected our fire suppression activity, if we needed activation or wash down,\u201d noted Sumner.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-95685\" class=\"size-full wp-image-95685\" src=\"https:\/\/www.nasaspaceflight.com\/wp-content\/uploads\/2023\/08\/DSC_1210-wmarked-scaled.jpg\" alt=\"\" width=\"2560\" height=\"1707\" srcset=\"https:\/\/www.nasaspaceflight.com\/wp-content\/uploads\/2023\/08\/DSC_1210-wmarked-scaled.jpg 2560w, https:\/\/www.nasaspaceflight.com\/wp-content\/uploads\/2023\/08\/DSC_1210-wmarked-350x233.jpg 350w, https:\/\/www.nasaspaceflight.com\/wp-content\/uploads\/2023\/08\/DSC_1210-wmarked-525x350.jpg 525w, https:\/\/www.nasaspaceflight.com\/wp-content\/uploads\/2023\/08\/DSC_1210-wmarked-768x512.jpg 768w, https:\/\/www.nasaspaceflight.com\/wp-content\/uploads\/2023\/08\/DSC_1210-wmarked-1920x1280.jpg 1920w, https:\/\/www.nasaspaceflight.com\/wp-content\/uploads\/2023\/08\/DSC_1210-wmarked-1170x780.jpg 1170w, https:\/\/www.nasaspaceflight.com\/wp-content\/uploads\/2023\/08\/DSC_1210-wmarked-585x390.jpg 585w, https:\/\/www.nasaspaceflight.com\/wp-content\/uploads\/2023\/08\/DSC_1210-wmarked-263x175.jpg 263w\" sizes=\"(max-width: 2560px) 100vw, 2560px\"><\/p>\n<p id=\"caption-attachment-95685\" class=\"wp-caption-text\">ML-2 rising out of the ground \u2013 via Julia Bergeron for NSF<\/p>\n<p>All damaged GN2 lines were replaced on the ML during its time at the West Park Site with some being hardened with additional shielding.&nbsp; Sumner added, \u201cWe saw some vibrations [at the base area] that were a little unexpected. Everything was hard piped, and so we\u2019re looking at ways if we can put some flex connections in there to give it a little bit more flexibility to move around.\u201d<\/p>\n<p>\u201cSo, there\u2019s a few different mitigations that we\u2019re doing there with the GN2 system, but it\u2019s coming along very well. We have a couple different contracts working on it right now and we will have the GN2 back up online here shortly, and we have [it] partially online now, but we\u2019re going to fully get through the system hopefully here by the end of August, and that\u2019ll put us back into fire suppression testing and some other GN2 testing that we have to do with that.\u201d<\/p>\n<p>Another noticeable area of damage was that of the elevators on the ML which required substantial refurbishment. \u201cThat design is still in work right now with our engineering teams, and it\u2019s basically a holistic design on hardening the elevator systems and the blast doors that get closed for launch,\u201d said Sumner.<\/p>\n<p>Inside the shaft, \u201cthe rails inside [that] the elevators ride on \u2026 we should be getting a design here in the next few weeks hopefully to start implementing and hardening that system so that we don\u2019t see the same damage and losses that we saw during Artemis I.\u201d<\/p>\n<p>Emergency Crew Escape System<\/p>\n<p>In order to support crew missions, ML-1 has been modified with the Emergency Crew Escape System. In the event of an on pad emergency, Wiseman, Glover, Koch, and Hansen would be required to evacuate the ML and pad via slide wire baskets immediately.<\/p>\n<p>Sumner explained that \u201cjust before going to the pad, we made quite a bit of progress as all the platforms were installed. We had the four pipeline hoists for the baskets and the cable themselves. Those are installed on level 325.\u201d<\/p>\n<p>\u201cOnce we get to the pad, we do have equipment being shipped here. The basket fabrication is coming along very well. We\u2019ve gone through probably about a little more than half or 75 percent of our factory acceptance testing. That\u2019ll prep us to be ready to ship those baskets out here to KSC in the next few weeks, and then we\u2019ll start getting the whole system set up.\u201d<\/p>\n<p>\u201cSo we\u2019re making really good progress on some big equipment that is finally starting to show up\u201d Sumner added. \u201cAt the same time, we\u2019re preparing all of our test plans, and we\u2019ll begin integrating the whole system and pulling it together. There is a lot to go and a short period of time though as well. Right now we\u2019re looking at trying to get everything tested in the next 90 days or so.\u201d<\/p>\n<p><iframe id=\"twitter-widget-2\" scrolling=\"no\" frameborder=\"0\" allowtransparency=\"true\" allowfullscreen=\"true\" class=\"\" style=\"position: static; visibility: visible; width: 0px; height: 0px; display: block; flex-grow: 1;\" title=\"X Post\" src=\"https:\/\/platform.twitter.com\/embed\/Tweet.html?creatorScreenName=NASASpaceflight&amp;dnt=true&amp;embedId=twitter-widget-2&amp;features=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%3D%3D&amp;frame=false&amp;hideCard=false&amp;hideThread=false&amp;id=1681365958567378945&amp;lang=en&amp;origin=https%3A%2F%2Fwww.nasaspaceflight.com%2F2023%2F09%2Fnasa-ml-1-artemis-ii-ml-2-construction%2F&amp;sessionId=fd4f006fca0a3ca043e43ab83115839b49301563&amp;siteScreenName=NASASpaceflight&amp;theme=light&amp;widgetsVersion=6a3ad42b224df%3A1778106238597&amp;width=550px\" data-gtm-yt-inspected-14=\"true\" data-gtm-yt-inspected-21=\"true\" data-tweet-id=\"1681365958567378945\"><\/iframe><\/p>\n<blockquote class=\"twitter-tweet\" data-width=\"550\" data-dnt=\"true\" data-twitter-extracted-i1783496297733243587=\"true\">\n<p lang=\"en\" dir=\"ltr\"><img decoding=\"async\" draggable=\"false\" role=\"img\" class=\"emoji\" alt=\"\ud83c\udfd7\" src=\"https:\/\/s.w.org\/images\/core\/emoji\/16.0.1\/svg\/1f3d7.svg\"> Mobile Launcher 1 Upgrades for Artemis<\/p>\n<p>This weekend, teams at the west park site at @NASAKennedy worked to lift a platform that will be used for mobile launcher 1&#8217;s emergency egress system. <\/p>\n<p>This platform will be where the emergency egress system baskets interface with the\u2026 pic.twitter.com\/9H9RUBcnM0<\/p>\n<p>\u2014 NASA&#8217;s Exploration Ground Systems (@NASAGroundSys) July 18, 2023<\/p>\n<\/blockquote>\n<p>Once the final installation is complete, integrated testing of the baskets will occur. \u201cDifferent scenarios are required \u2013 fairly extensive as far as the varying weight conditions, wind conditions, wind direction, and wind speed.

Those are going to start on a daily cycle hopefully here in the next two or three weeks.\u201d Teams plan to put the access arm through its series of swing tests and complete certification before the ML is needed back in the VAB for stacking.<\/p>\n<p><iframe id=\"twitter-widget-3\" scrolling=\"no\" frameborder=\"0\" allowtransparency=\"true\" allowfullscreen=\"true\" class=\"\" style=\"position: static; visibility: visible; width: 0px; height: 0px; display: block; flex-grow: 1;\" title=\"X Post\" src=\"https:\/\/platform.twitter.com\/embed\/Tweet.html?creatorScreenName=NASASpaceflight&amp;dnt=true&amp;embedId=twitter-widget-3&amp;features=eyJ0ZndfdGltZWxpbmVfbGlzdCI6eyJidWNrZXQiOltdLCJ2ZXJzaW9uIjpudWxsfSwidGZ3X2ZvbGxvd2VyX2NvdW50X3N1bnNldCI6eyJidWNrZXQiOnRydWUsInZlcnNpb24iOm51bGx9LCJ0ZndfdHdlZXRfZWRpdF9iYWNrZW5kIjp7ImJ1Y2tldCI6Im9uIiwidmVyc2lvbiI6bnVsbH0sInRmd19yZWZzcmNfc2Vzc2lvbiI6eyJidWNrZXQiOiJvbiIsInZlcnNpb24iOm51bGx9LCJ0ZndfZm9zbnJfc29mdF9pbnRlcnZlbnRpb25zX2VuYWJsZWQiOnsiYnVja2V0Ijoib24iLCJ2ZXJzaW9uIjpudWxsfSwidGZ3X21peGVkX21lZGlhXzE1ODk3Ijp7ImJ1Y2tldCI6InRyZWF0bWVudCIsInZlcnNpb24iOm51bGx9LCJ0ZndfZXhwZXJpbWVudHNfY29va2llX2V4cGlyYXRpb24iOnsiYnVja2V0IjoxMjA5NjAwLCJ2ZXJzaW9uIjpudWxsfSwidGZ3X3Nob3dfYmlyZHdhdGNoX3Bpdm90c19lbmFibGVkIjp7ImJ1Y2tldCI6Im9uIiwidmVyc2lvbiI6bnVsbH0sInRmd19kdXBsaWNhdGVfc2NyaWJlc190b19zZXR0aW5ncyI6eyJidWNrZXQiOiJvbiIsInZlcnNpb24iOm51bGx9LCJ0ZndfdXNlX3Byb2ZpbGVfaW1hZ2Vfc2hhcGVfZW5hYmxlZCI6eyJidWNrZXQiOiJvbiIsInZlcnNpb24iOm51bGx9LCJ0ZndfdmlkZW9faGxzX2R5bmFtaWNfbWFuaWZlc3RzXzE1MDgyIjp7ImJ1Y2tldCI6InRydWVfYml0cmF0ZSIsInZlcnNpb24iOm51bGx9LCJ0ZndfbGVnYWN5X3RpbWVsaW5lX3N1bnNldCI6eyJidWNrZXQiOnRydWUsInZlcnNpb24iOm51bGx9LCJ0ZndfdHdlZXRfZWRpdF9mcm9udGVuZCI6eyJidWNrZXQiOiJvbiIsInZlcnNpb24iOm51bGx9fQ%3D%3D&amp;frame=false&amp;hideCard=false&amp;hideThread=false&amp;id=1677063959881424897&amp;lang=en&amp;origin=https%3A%2F%2Fwww.nasaspaceflight.com%2F2023%2F09%2Fnasa-ml-1-artemis-ii-ml-2-construction%2F&amp;sessionId=fd4f006fca0a3ca043e43ab83115839b49301563&amp;siteScreenName=NASASpaceflight&amp;theme=light&amp;widgetsVersion=6a3ad42b224df%3A1778106238597&amp;width=550px\" data-gtm-yt-inspected-14=\"true\" data-gtm-yt-inspected-21=\"true\" data-tweet-id=\"1677063959881424897\"><\/iframe><\/p>\n<blockquote class=\"twitter-tweet\" data-width=\"550\" data-dnt=\"true\" data-twitter-extracted-i1783496297733243587=\"true\">\n<p lang=\"en\" dir=\"ltr\"><img decoding=\"async\" draggable=\"false\" role=\"img\" class=\"emoji\" alt=\"\ud83c\udfd7\ufe0f\" src=\"https:\/\/s.w.org\/images\/core\/emoji\/16.0.1\/svg\/1f3d7.svg\"> Mobile Launcher 1 Upgrades for Artemis<\/p>\n<p>This time-lapse from today shows the mobile launcher&#8217;s crew access arm in motion as teams from Exploration Ground Systems conduct a functional test at @NASAKennedy&#8217;s west park site.<\/p>\n<p>This test of the 92k-pound arm and hinges, in addition\u2026 pic.twitter.com\/5pK9xdAdWk<\/p>\n<p>\u2014 NASA&#8217;s Exploration Ground Systems (@NASAGroundSys) July 6, 2023<\/p>\n<\/blockquote>\n<p>While the majority of testing is scheduled to be completed in November, crews at 39B will be kept busy completing additional work that will take them into the December-January timeframe.
