It was built in 1965 at a cost of $3.5 million and is now called the Impact Dynamics Research Facility.","why_significant":"It trained Apollo astronauts to pilot a lunar landing vehicle in a simulated lunar gravity environment. Neil Armstrong and Edwin Aldrin trained there before NASA approved their first Moon landing in July 1969. The nomination calls it an indispensable tool that enabled NASA to land a man on the Moon by 1969.","narrative":"Rising 230 feet above Langley Research Center in Hampton, Virginia, this steel A-frame gantry was completed in 1965 for $3.5 million. It was built to train Apollo astronauts for the final phase of a lunar landing. An overhead cable and crane system, working through a full-scale Lunar Excursion Module, cancelled all but one-sixth of Earth's gravity, so pilots could feel the vehicle's handling as it would behave near the Moon. The base was shaped with fill dirt into a cratered lunar surface, and a separate inclined walkway let astronauts practice lunar walking. Neil Armstrong and Edwin Aldrin trained here for many hours, and NASA approved their July 1969 landing only after they mastered the vehicle. The structure survives largely intact. It is now used for aircraft crash testing, with an impact runway replacing the simulated moonscape.","period_of_significance":"1965-1972","architect_builder":"NASA","architectural_style":null,"criteria":[],"status_note":"Intact and retaining almost all of its design integrity. It is now used by NASA Langley for aircraft crash impact studies, with the lunar surface and walkway removed and the Lunar Excursion Module still on site.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:51:56.911325-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/opastorage/live/47/6790/41679047/content/electronic-records/rg-079/NPS_VA/85002808_NHL.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/85002808/cc8e8a5e7b-800.webp","url_1600":"https://nationalhistoricalregister.com/media/85002808/cc8e8a5e7b-1600.webp","licence":"Public domain","author":"NASA Bob Nye","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Drop_Test_at_Lunar_Landing_Research_Facility_-_GPN-2000-001287.jpg\" rel=\"noopener\">NASA Bob Nye</a>, Public domain, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Drop_Test_at_Lunar_Landing_Research_Facility_-_GPN-2000-001287.jpg"},"district":{"nrhp_refnum":"12000374","name":"NASA Langley Research Center (LaRC) Historic District","url":"https://nationalhistoricalregister.com/districts/virginia/nasa-langley-research-center-larc-historic-district-12000374/"},"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/41679047","wikipedia":"https://en.wikipedia.org/wiki/Lunar_Landing_Research_Facility","wikidata":"https://www.wikidata.org/wiki/Q1877358"},"indexable":true,"url":"https://nationalhistoricalregister.com/virginia/hampton/lunar-landing-research-facility-85002808/"}
