Chamber Services for decompression sickness testing of CO2 countermeasures.

The National Aeronautics and Space Administration Shared Services Center is soliciting chamber services for decompression sickness testing of CO2 countermeasures through Request for Quotation (RFQ) Number 80NSSC26920246Q-1. The procurement requires a qualified vendor to provide hypobaric chamber services and specialized medical testing capabilities to support the development of the Aerospace Estimation Tool for Hypobaric Exposure Risk (AETHER), a decompression sickness risk estimation tool. Key requirements include maintaining a decompression chamber capable of continuous habitation, providing medical monitoring capabilities, conducting six-hour simulated extravehicular activity (EVA) exercises, performing ultrasound imaging with Doppler capability, and managing comprehensive physiological data collection on six research subjects across three test conditions. Offerors must demonstrate prior NASA-funded pilot or proficiency completion and possess integrated experience in prebreathe protocols, hardware integration with Gentex Phantom oxygen masks, and EVA execution across eight workstations. The Government will evaluate all offers on a lowest price technically acceptable (LPTA) basis, with quotes due by January 29, 2026, at 7:00 a.m. CT, and all contractual and technical questions must be submitted in writing by January 28, 2026, at 7:00 a.m. CT to the contracting officer.

This solicitation is set aside for small business concerns, and no current incumbent contractor is identified in the available documentation. While no specific award value is disclosed in the solicitation materials, the contract is structured on a firm fixed-price basis with payment milestones to be established by the vendor. The work encompasses testing of six subjects (aged 30-60 with VO2max greater than 27.5 ml/min/kg who pass Air Force Class III physical examinations) across three test conditions to be completed within one year, with an anticipated contract start date of February 2026. All offerors must be registered in SAM.gov, provide a CAGE/UEI code, and include two points of contact with contact information in their submissions, referencing tracking number 80NSSC26920246Q-1 in the email subject line. The place of performance is Houston, TX 77058, USA, with delivery on an FOB Destination basis, and vendors must note that NASA does not accept payment by credit card.
