NASA's Goddard Space Center awarded a $4.5 million definitive contract to the Regents of the University of Michigan for the SUNRISE (The Sun Radio Interferometer Space Experiment) Phase A concept study on February 12, 2018, with an ultimate completion date of December 31, 2026, under cost-no-fee pricing.

The originating solicitation, submitted in response to NASA's 2016 Heliophysics Small Explorer announcement, requires the University of Michigan to deliver a Phase A Concept Study Report encompassing principal investigator program office direction, instrument system engineering with mission assurance, design of a flight-qualified SUNRISE instrument meeting mission and science requirements, development of integration and test plans, field operations plans, launch and flight operations plans, and leadership of the science investigation team including resulting data product generation. The University of Michigan shall develop instrument and mission systems requirements documents, conduct detailed block diagrams and technical descriptions, perform instrument-level design reviews and trade studies, lead the science team, develop test planning, and prepare a detailed instrument development schedule. Place of performance is Ann Arbor, MI.

In FY2025, the contract invoiced $243 thousand across 1.1 FTEs with no subcontractor engagement; the prime self-performed all reported work. The California Institute of Technology is named as a subcontractor on this award.

The sun radio interferometer space experiment (sunrise) is proposed by university of michigan (UM) in response to NASA's 2016 heliophysics small explorer (smex) announcement of opportunity. This statement of work (SOW) describes the work to be conducted by UM during the phase a (sunrise) project. UM shall provide the necessary personnel, materials, equipment, and facilities to produce the sunrise phase a concept study report (CSR) that encompasses: 1. Principal investigator program office. 2. Instrument system engineering, including instrument mission assurance. 3. Design of a flight qualified sunrise instrument meeting mission and science requirements. 4. Develop plans in support of integration and test of the sunrise instrument flight system. 5. Develop plans in support of essential field operations 6. Develop plans in support of launch operations, flight operations. 7. Develop plans for and lead the sunrise science investigation, as well as the generation of resulting data products. UM shall provide a briefing on the sunrise science and science implementation plan at the phase a site visit. UM shall provide an organization chart defining UM roles and responsibilities, reporting procedures, and lines of authority. Participate in defining the relationships between the UM PI program office and the NASA explorers program office. UM shall develop a sunrise instrument systems requirements document and a sunrise mission systems requirements document. UM shall develop detailed block diagrams and technical descriptions of all instrument systems. UM shall conduct in-depth instrument-level reviews of the proposed instrument design. Conduct essential trade studies, analyses, modeling and simulations to assure compliance with instrument requirements. UM shall lead the science team. UM shall develop an instrument-level test plan and participate in planning for integration and test. UM shall prepare a detailed instrument development schedule covering all mission phases, listing major milestones and including a defined critical path and schedule reserves.
