NASA records state the Hangar One restoration was finished in December 2025 under Planetary Ventures, the lessee operating Moffett Federal Airfield. (nasa.gov) The project removed decades-old contamination by sectionally encasing work areas with scaffolding, extracting contaminated siding and roofing materials for off-site disposal, then priming and repainting the steel frame before installing new siding, windows and doors. (nasa.gov) Officials say specific toxins identified during earlier testing included polychlorinated biphenyls (Aroclor 1260 and 1268), with Planetary Ventures removing the remaining toxic materials in 2022 as part of the cleanup. (nasa.gov) Restoration work also included structural reinforcements plus upgrades to mechanical, plumbing and electrical systems and to landscape and hardscape to ensure long-term operational integrity. (nasa.gov) Under the 2014 lease terms, Planetary Ventures committed to invest more than $200 million in capital improvements and agreed to a 60-year arrangement that NASA estimated would provide $1.16 billion in rent while saving the agency roughly $6.3 million a year in upkeep. (nasa.gov) Local leaders and Planetary Ventures representatives marked the recent unveiling at Moffett Field, with statements tying the completed rehabilitation to plans for public-facing educational programming and reuse of Hangars Two and Three under the lease commitments.
