The forward skirt for #Artemis IV's @NASA_SLS rocket is moving on to the next stage of production at #NASAMichoud . 🚀The hardware houses flight computers, cameras, and avionics systems for the SLS rocket.Learn more HERE>> https://www.nasa.gov/exploration/systems/sls/index.html
Considering that ML2 had been significantly delayed what are the chances that this rocket will be completed years ahead of time and just sit dormant in a warehouse to gather dust? Do they have a shelf life before it needs a deep teardown for inspection?

You would have to completely ditch the VAB and crawlers to do a TEL. It's not a simple matter.

The pieces may sit in a warehouse, but the mobile launcher must be complete before they can actually build (stack) the rocket. In effect, it's already in a "deep teardown" state until it begins stacking.

It's not a simple matter.The Mobile Launcher used for the SLS is indeed the slowest-ever mobile launch platform for an SLV, reaching a top speed of 1 mile per hour. The unsuccessful N1 rocket was transported to its launch pad by a railroad-based vehicle.

Dan is stating that the ML must be completed before ANY stacking ops can begin. You are the only person I've read about thinking a TE(Transporter Erector) is a viable solution over Crawler Transporter(CT).
The Artemis 4 schedule will also depend on the readiness of the I-Hab module, being developed by Europe and Japan, and the SLS Block 1B itself.
Transport time!🚚The pressure vessel for #Artemis IV is ready to ship from Michoud Assembly Facility to @NASAKennedy, where it will become the third Orion spacecraft to carry crew to the Moon

Surprising to see the pressure vessel for the Orion spacecraft earmarked for Artemis IV getting ready for shipment to Kennedy Space Center regardless of that mission being a long way off.
Just goes to show that if they really wanted to they could speed up construction significantly. Most of the delays is all due to mismanagement, funding and bureaucratic red tape

#Artemis IV @NASA_Orion crew module pressure vessel arrives at @NASA_Kennedy. Our spacecraft factory is in full swing with 3 Orion vehicles being prepared to carry humans to the Moon.
Development, integration, and operation of NASA space flight systems will become more complex and expensive beginning with the fourth #Artemis mission. Today we are announcing an audit examining NASA’s management of these missions beginning with Artemis IV.
NASA_SLS@NASA_SLSThe universal stage adapter will debut during #Artemis IV and will connect @NASA_Orion to the exploration upper stage on future SLS rockets in the Block 1B configuration.Read more about the test version of the adapter that was recently moved>>https://go.nasa.gov/4cc785I
Apr 16, 2024 #Artemis #NASA #SLSTeams at NASA’s Marshall Space Flight Center in Huntsville, Alabama, completed a new payload adapter test article and readied it for structural testing, set to begin later this spring. This marks a critical milestone on the journey to the hardware’s debut on the upgraded Block 1B configuration of NASA’s SLS (Space Launch System) rocket with Artemis IV. The composite payload adapter is an evolution from the Orion stage adapter used in the Block 1 configuration of the first three Artemis missions.
Sep 8, 2024The arrival this past week of new Orion and SLS flight hardware at Kennedy Space Center for Artemis II, III, and IV is a reminder of the uncertain launch schedule. This video covers those deliveries, of the Artemis II SLS Launch Vehicle Stage Adapter, Artemis II Orion European Service Module, and SLS Core Stage engine section hardware for Artemis III and IV.Artemis II is scheduled for launch only one year from this month, and most of the SLS hardware for Artemis II is now in and around the Vehicle Assembly Building. In this video, we also cover plans and preparations for the launch campaign in the second part of an interview with Exploration Ground Systems senior vehicle operations manager Cliff Lanham.Meanwhile, the next milestones for that newly-delivery hardware are known in general, but when those and other Artemis III milestones will happen is harder to see. We go over the cloudy forecast and other Artemis III takeaways from the late August NASA Advisory Council meeting here, too.Imagery is courtesy of NASA, except where noted.00:00 Intro02:13 A week of Orion and SLS flight hardware deliveries to KSC03:00 ESM-3 arrives in Orion final assembly at KSC04:21 Core Stage engine section hardware packaged for shipment at MAF06:45 Offloading SLS triple shipment from Pegasus at KSC09:12 EGS senior manager Cliff Lanham talks to the podcast about Artemis II launch plans10:13 Improving launch availability with contingency pad access capability18:36 Artemis II pad flow from rollout to launch20:35 Integrating the astronaut crew ingress of Orion into the launch countdown24:05 Artemis III takeaways from NASA Exploration public report in NASA Advisory Council meeting25:12 "At least" one uncrewed HLS lunar landing demonstration?25:53 Outlook for the future remains cloudy only two years from Artemis III launch date27:55 Thanks for watching!Chapters
This image shows teams at NASA’s Michoud Assembly Facility in New Orleans lifting a forward skirt out of its vertical assembly center on Jan. 31, 2025. The forward skirt, which will be used on the core stage for the agency’s SLS (Space Launch System) rocket for its Artemis IV mission, houses flight computers, cameras, and avionics. While inside the vertical assembly center, technicians attached the forward skirt’s forward and aft rings, which serve as attachments points to the launch vehicle stage adapter and the liquid oxygen tank, respectively.
