Subsea Habitat Operations and Saturation Diving Support

The contract requires the provision and operation of a subsea habitat equipped with comprehensive life support systems to sustain two to four participants under saturation diving conditions for a minimum of five consecutive days. The habitat must maintain a stable, pressurized environment identical to the depth at which operations occur, ensuring the physiological safety and operational readiness of the crew throughout the mission duration. All systems including air supply, CO2 scrubbing, temperature control, communication, emergency protocols, and waste management must function reliably under extreme underwater conditions without external intervention. This subcontract, issued by NASA Johnson Space Center, is intended to support advanced human performance and systems testing relevant to deep-sea and space exploration analogs. The place of performance is specified as a location with a zip code of 77058, consistent with the Houston, Texas area, where NASA JSC is based, suggesting the habitat may be tested in a controlled marine facility nearby. The solicitation was posted on June 22, 2026, with responses due by July 6, 2026, and falls under the NAICS code 238990 for other specialty trade contractors, indicating the work involves specialized non-standard construction and operational support. No set-aside provisions are specified, and the contract is open to all qualified offerors capable of delivering a fully functional, crew-rated subsea habitat under demanding saturation diving parameters.
