Project and Engineering Support Services II (PESS II) Extension

The National Aeronautics and Space Administration (NASA) has issued a Justification and Approval (J&A) for a contract extension to Millennium Engineering and Integration Services (MEIS) under contract 80ARC021D0001. This action extends the Project and Engineering Support Services II (PESS II) contract, which was originally awarded in December 2020. The extension includes a twelve-month base period and two six-month option periods, totaling two years of additional performance from April 1, 2026, through March 31, 2028. This requirement is classified under NAICS 541715 for Research and Development in the Physical, Engineering, and Life Sciences (except Nanotechnology and Biotechnology) and PSC AR11 for Space R&D Services; Space Flight, Research and Supporting Activities; Basic Research.

The PESS II contract provides NASA Ames Research Center (ARC) with engineering support services necessary to design new mission concepts and develop cost-efficient engineering products. These services facilitate the operation of critical research facilities, including wind tunnels, arc jets, simulators, ballistic ranges, and aerospace hangars. Work also involves support for flight and mission operations, computer laboratories, and various fabrication facilities such as machine and model shops. The contract is structured as a cost-plus-fixed-fee (CPFF) hybrid, incorporating firm-fixed-price (FFP) elements for phase-in and CPFF components for core technical management and indefinite delivery/indefinite quantity (IDIQ) requirements.

This notification was published on April 6, 2026, by the National Aeronautics and Space Administration and includes one attachment: a redacted Justification for Other than Full and Open Competition (JOFOC) document. The primary point of contact for this action is Noor Khazendar. The extension ensures the continued availability of engineering expertise and the maintenance of state-of-the-art research laboratories and test chambers essential to meeting NASA mission goals.
