The ''Samuel Oschin Air and Space Center'', a new building that is under construction, will serve as ''Endeavour's'' new permanent home. The Space Shuttle will be in a 20-story-tall display mounted on with the ET-94 tank, and solid rocket boosters. Once finished, it will be the only Space Shuttle mounted vertically in [[Launch pad|launch position]]. 

Originally slated to open in 2015, construction on the new building started on June 1, 2022.<ref>{{Cite news |last1=Lin II |first1=Rong-Gong |last2=Campa |first2=Andrew J. |date=June 1, 2022 |title=Space shuttle Endeavour is getting its own grand museum in L.A., displayed in launch position |url=https://www.latimes.com/california/story/2022-06-01/endeavour-space-shuttle-california-science-center-groundbreaking |access-date=June 4, 2022 |work=Los Angeles Times}}</ref><ref>{{Cite web |last=Wisdom |first=McKenzie |date=June 9, 2022 |title=Groundbreaking at California Science Center's Samuel Oschin Air and Space Center |url=https://www.mattconstruction.com/blog/non-profit/groundbreaking-at-california-science-centers-samuel-oschin-air-and-space-center/ |access-date=October 11, 2023 |website=MATT Construction |language=en-US}}</ref> Meanwhile, the ET-94 tank underwent some restoration after being used to analyze the foam on its sister tank, ET-93, which was a factor during the [[STS-107]] mission, which resulted in the [[Space Shuttle Columbia disaster|Columbia disaster]].<ref>{{Cite news |last=Branson-Potts |first=Hailey |date=April 10, 2016 |title=Last flight-qualified space shuttle fuel tank in existence begins its journey to L.A. |url=https://www.latimes.com/local/california/la-me-0411-space-shuttle-tank-20160411-story.html |access-date=April 20, 2019 |work=[[Los Angeles Times]]}}</ref>

On July 20, 2023, the assembly of the stack began with the aft skirts (bottom segments of the rocket boosters) being precisely positioned on a concrete slab supported by six [[Seismic base isolation|base isolators]] that will protect ''Endeavour'' from earthquakes.<ref>{{Cite news |date=July 20, 2023 |title=California Science Center starts complex process to display Space Shuttle Endeavour vertically |url=https://ktla.com/news/local-news/ap-california-science-center-starts-complex-process-to-display-space-shuttle-endeavour-vertically/ |access-date=July 21, 2023 |work=KTLA |language=en-US |agency=Associated Press}}</ref> The motors for the rocket boosters, which were in storage at the [[Mojave Air and Space Port]],  were installed on October 11, 2023.<ref>{{Cite web |last=Staff |first=KCAL News |date=2023-10-11 |title=Massive rocket motors arrive at California Science Center - CBS Los Angeles |url=https://www.cbsnews.com/losangeles/news/massive-rocket-motors-arrive-at-california-science-center/ |access-date=2024-10-09 |website=www.cbsnews.com |language=en-US}}</ref> The rocket boosters were fully assembled when the tops were added on December 5, 2023.<ref>{{Cite web |title=Endeavour's Final Move |url=https://californiasciencecenter.org/about-us/samuel-oschin-air-and-space-center/go-for-stack |website=California Science Center}}</ref>  

On January 3, 2024, ''Endeavour'' was protected in a shrink wrap, likely to stay on until construction is complete.<ref>{{Cite web |last=Pearlman |first=Robert |date=January 3, 2024 |title=Up next for Endeavour LA exhibit: Tank lift and shuttle shrink wrap |url=https://news.yahoo.com/next-endeavour-la-exhibit-tank-200043669.html |access-date=April 3, 2024 |website=Yahoo News |language=en-US}}</ref> The ET-94 tank was then moved into its position in January 16 and was mounted to the rocket boosters.<ref>{{Cite news |last=Lin II |first=Rong-Gong |date=January 2, 2024 |title=Space shuttle Endeavour's giant orange external tank begins final journey |url=https://www.latimes.com/california/story/2024-01-02/space-shuttle-endeavours-giant-orange-external-tank-begins-final-journey |access-date=January 3, 2024 |work=Los Angeles Times |language=en-US}}</ref><ref>{{Cite web |last1=Campa |first1=Andrew J. |last2=Lin II |first2=Rong-Gong |date=January 12, 2024 |title=Mission accomplished: Space shuttle Endeavour's giant orange fuel tank moved into viewing spot in L.A. |url=https://www.latimes.com/california/story/2024-01-12/shuttle-endeavours-giant-orange-fuel-tank-lifted-but-winds-delay-final-placement |access-date=January 16, 2024 |website=Los Angeles Times |language=en-US}}</ref> On January 30, the Space Shuttle was then moved into its position, thus completing the stack.

It will take several more years to install the artifacts and exhibits inside the building.<ref>{{Cite web |date=2024-10-10 |title=The Endeavour space shuttle's new home is inching closer to completion |url=https://laist.com/news/endeavour-space-shuttle-milestone-topping-out |access-date=2024-10-11 |website=LAist |language=en}}</ref> An official grand opening is not yet announced.
