NASA's Ames Research Center is seeking to procure extended mission operations for the Pathfinder Technology Demonstrator (PTD) Missions, specifically PTD-R and PTD-4. The procurement includes mission operations, flight product generation, fault management, and software support, with the goal of extending operations until spacecraft demise in January 2027 for PTD-R and for an additional two months for PTD-4. This initiative is critical for maintaining the operational integrity of the PTD missions, which are vital for advancing space research and technology. Interested organizations may submit their capabilities and qualifications to Tiffany N. Goodwin and Joshua D. Taggart via email within seven days of this notice, as the government intends to issue a sole source contract to Tyvak Nano-Satellite Systems, Inc. for these services.
