AI Contract Overview
NASA's Glenn Research Center intends to award a sole source, firm fixed-price contract to Hamilton Sundstrand Space Systems International, Inc. for engineering services related to high-temperature, space-qualified pumps. These pumps, which are NASA property but utilize a proprietary HSSSI design, were originally developed for the Parker Solar Probe Solar Array Cooling System. The scope of work involves performing analyses for a new operational regime and completing hardware assembly to ensure the pumps meet specific project needs. The project follows a strict timeline, requiring ground test hardware by the first half of 2027 and flight hardware delivery by Fall 2027 to support system level testing. This procurement is conducted under FAR Part 12 and NAICS code 541330. While NASA intends to proceed with HSSSI as the only responsible source, interested organizations were invited to submit capabilities and qualifications by September 1, 2026, to determine if the acquisition should be conducted on a competitive basis.

Full Description
NASA’s Glenn Research Center (GRC) intends to negotiate a sole source contract with Hamilton Sundstrand Space Systems International, Inc. (HSSSI, Collins Aerospace) for engineering services for the high-temperature, space-qualified pumps owned by NASA and previously developed for the Parker Solar Probe (PSP) Solar Array Cooling System. The pumps are a proprietary design from HSSSI.
The PSP pumps are currently located in HSSSI inventory but are NASA property. This includes multiple pump assemblies and controllers, both flight and ground test units. The engineering services being solicited enable the use of these existing pumps by performing analyses related to the new operational regime and completion of hardware assembly. The pumps have been identified to fit the project needs and the schedule to meet these needs requires delivery of flight hardware by Fall-2027 (~12 months), to support system level testing near the end-2027. Ground test hardware must be available in H1 2027.
This procurement is being conducted in accordance with FAR Part 12 – Acquisition of Commercial Products and Commercial Services. NASA GRC anticipates awarding a firm fixed-price contract to HSSSI, Inc. as the only responsible source reasonably available to satisfy the agency requirements under the authority of FAR 6.103-1(b).
The applicable NAICS Code is 541330 - Engineering Services
