Manufactured Gearbox for the Urine Distillate Separator in Uncrewed Dormancy

The National Aeronautics and Space Administration Shared Services Center (NASA/NSSC) has issued a Special Notice for a sole source procurement of a Manufactured Gearbox for the Urine Distillate Separator in Uncrewed Dormancy. This procurement is set aside for Total Small Business and involves manufacturing eight specific gearbox components for NASA's Environmental Control and Life Support Systems (ECLSS). The components include titanium and aluminum housings, gear assembly, Inconel shafts, bearings and shims, all with precise specifications and tolerances. NASA intends to award this contract to Machine-Tech under FAR 13.106-1(b)(1)(i), having determined that Machine-Tech is the sole provider of this specialized gearbox. The procurement falls under NAICS Code 334516 for Analytical Laboratory Instrument Manufacturing and PSC Code 6640 for Laboratory Equipment and Supplies.

The primary purpose of this procurement is to create functionally identical components to those currently aboard the International Space Station (ISS) for use in a dormancy test stand to evaluate the impact of system dormancy on critical life support equipment. Manufacturing must be completed at the vendor's facility prior to October 31, 2025, with performance taking place at NASA Marshall Space Flight Center. Interested organizations may submit their capabilities and qualifications in writing to the designated point of contact by 4:00 p.m. Central Standard Time on July 11, 2025. The government will evaluate these submissions solely to determine whether to conduct the procurement on a competitive basis, though oral communications are not acceptable. Key requirements include using correct stock material series and grades, validating dimensions and tolerances according to drawing instructions, and completing manufacturing in a timely manner to support NASA's ECLSS dormancy evaluation program.
