The National Aeronautics and Space Administration (NASA) is seeking to modify Contract No. NNA17BF41C for the Pathfinder Technology Demonstrator (PTD) Project, currently held by Tyvak Nano-Satellite Systems, Inc., on a sole-source basis. The modification aims to enhance Mission Operations Support for the PTD-R and PTD-4 missions and to incorporate an additional energy experiment into PTD-4, addressing delays that have impacted previous launch opportunities. This project is critical for testing novel satellite technologies in low Earth orbit, which will significantly improve the performance of small spacecraft. Interested organizations are invited to submit their capabilities and qualifications to the Contracting Officer, Tiffany Goodwin, via email by 12 PM PDT on November 29, 2024, to determine the potential for competitive acquisition.
