Notice of Intent to Sole Source

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
