NASA/GSFC intends to issue a sole source contract modification to increase the ceiling by $75.6 million and extend the period of performance for Electrical Systems Engineering Services. The extension includes a base period of 4 months and two 4-month options, potentially extending the contract through December 8, 2025, to allow for the continuation of mission-critical services. The work involves engineering support for space flight, airborne, and ground system hardware and software for the Engineering and Technology Directorate. The modification is intended for the current contractor, Science Systems and Applications, Inc. (SSAI), pending a competitive follow-on procurement.
