This partnership opportunity is being issued to select teaming partner(s) to serve as the satellite integrator for an individual mission; provide flight-qualified Class C spacecraft bus (our mission is not compatible with a CubeSat platform), instrument to spacecraft integration support, environmental testing, integration support for the spacecraft to launch vehicle, and initial mission operations (launch and early orbit operations). GSFC intends to maintain an essential degree of insight into satellite integration and will exercise essential oversight to ensure that the implementation is responsive to NASA requirements and constraints as will be defined in upcoming AO.
