Vacuum Chamber 1. 1 for LESTR 2- additional parts specified in SOW

The National Aeronautics and Space Administration Shared Services Center (NASA SSC) is seeking to procure a specialized Vacuum Chamber 1.1 for the Lunar Electric Spacecraft Test and Research (LESTR) 2 project. The solicitation requires a 16" cubic vacuum chamber with specific technical specifications, including a vacuum operating pressure of 1*10^-6 Torr or better, front swing-out door capabilities, and multiple conflat interfaces. The procurement will be awarded using a lowest-price technically acceptable methodology, with vendors required to provide comprehensive documentation including compliance certifications, detailed drawings, and inspection reports. Potential bidders must meet NASA-STD-8719.17D standards for ground-based pressure vessels and demonstrate technical capability to fabricate the chamber from 300 series stainless steel or 6061-T6 aluminum. The solicitation was posted on April 22, 2025, with quotes due by April 29, 2025 at 12 p.m. CT, giving potential contractors a short window to prepare and submit their proposals.

The contract is not set aside for any specific small business designation, opening competition to a broad range of manufacturers in the measuring and controlling device manufacturing sector (NAICS 334519). While specific award values are not disclosed, the procurement appears to be for a single, highly specialized vacuum chamber unit designed for NASA's space technology research infrastructure. The chamber must be capable of ambient temperature operation and integrate with mechanical test system components. The place of performance is not explicitly stated, but given NASA's involvement, it is likely to be at one of their research facilities involved with the LESTR 2 project. The technical complexity of the vacuum chamber, as detailed in the accompanying engineering drawings (document 120701-LESTR-2A), suggests this is a precise, mission-critical component for advanced spacecraft testing and research purposes.
