The National Aeronautics and Space Administration (NASA) is seeking information from potential sources for the development of a cost-effective technology demonstration mission spacecraft bus, with the goal of enabling the operation of multiple integrated technologies to collect performance data. The spacecraft is expected to launch between 2030 and 2032, with a mission duration of 8 to 12 months, and will require capabilities such as a 500 km sun-synchronous orbit, a payload capacity of approximately 1000 kg, and advanced communication and power generation systems. Interested parties must submit a capability statement by April 30, 2025, to Kathy Cooper at kathy.cooper@nasa.gov, and R. Jeremy Kenny at robert.j.kenny@nasa.gov, detailing their qualifications and ability to meet the specified requirements.
