The mission has been procured by the DoD Space Test Program in partnership with Defense Innovation Unit (DIU) as part of its Rapid Agile Launch Initiative .The payload consists of three satellites, SPARC-1, Falcon ODE and Harbinger, that will deployed in a precise sequence. The Space Plug and Play Architecture Research CubeSat-1 (SPARC-1) mission, sponsored by the Air Force Research Laboratory Space Vehicles Directorate (AFRL/RV), is a joint Swedish-United States experiment to explore technology developments in avionics miniaturization, software defined radio systems, and space situational awareness (SSA). The Falcon Orbital Debris Experiment (Falcon ODE), sponsored by the United States Air Force Academy, will evaluate ground-based tracking of space objects. Harbinger, a commercial small satellite built by York Space Systems and sponsored by the U.S Army, will demonstrate the ability of an experimental commercial system to meet DoD space capability requirements.
