NASA's National Aeronautics and Space Administration (NASA) is seeking to procure wide masks and hardshells to support decompression sickness testing, with the intention of awarding a sole source contract to ECI Defense Group, Inc., the sole provider of these specialized items. The procurement will be managed by NASA's Shared Services Center and will take place at the NASA Johnson Space Center in Houston, Texas. These items are critical for ensuring the safety and effectiveness of testing protocols related to decompression sickness, which is vital for astronaut health and mission success. Interested organizations may submit their capabilities by 1 p.m. CST on December 5, 2025, to Cara Craft at cara.s.craft@nasa.gov for consideration, although the decision to pursue a competitive basis remains at the government's discretion.
