About this opportunity
NASA's Glenn Research Center announced on August 17, 2026, its intent to sole source a contract with Hamilton Sundstrand Space Systems International, Inc. (Collins Aerospace) for engineering services supporting high-temperature, space-qualified pumps developed for the Parker Solar Probe Solar Array Cooling System; interested organizations may submit capability statements by September 1, 2026, to challenge the sole-source determination. The pumps, NASA property currently held in HSSSI inventory, require engineering analyses for a new operational regime and hardware assembly completion. Flight hardware must be delivered by Fall 2027 to support system-level testing in late 2027, with ground test hardware required by H1 2027. NASA will acquire this work under FAR Part 12 (commercial products and services) on a firm fixed-price basis under FAR 6.103-1(b) authority, citing HSSSI as the only responsible source reasonably available. NAICS code 541330 applies. Capability statements submitted via email to the identified point of contact by 5:00 p.m. EST on September 1, 2026, will be evaluated solely to determine whether competitive acquisition is warranted; the Government reserves discretion to reject the sole-source justification and compete the effort.
Notice text
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
Interested organizations may submit their capabilities and qualifications to perform the effort electronically via email to the identified point of contact not later than 5:00 p.m. Eastern Standard Time on September 1, 2026. Such capabilities/qualifications will be evaluated solely for the purpose of determining whether or not to conduct this acquisition on a competitive basis. A determination by the Government not to compete this acquisition on a full and open competition basis, based upon responses to this notice, is solely within the discretion of the Government.
Oral communications are not acceptable in response to this notice.
NASA Clause 1852.215-84, Ombudsman, is applicable. The Center Ombudsman for this acquisition can be found at: https://www.hq.nasa.gov/office/procurement/regs/Procurement-Ombuds-Comp-Advocate-Listing.pdf
