This work is at the intersection of and integrates two broad considerations in the space industry, namely the emergence of the hosted payload paradigm on the one hand, and the increased emphasis for the acquisition of space systems to be value-driven on the other hand. Spacecraft, and hosted payloads, are value delivery artifacts; their value derives from the flow of service they provide to different stakeholders. Their design and acquisition should be value-centric or at a minimum value-informed.
