... Mission selection involves many users of information, including managers at NASA Headquarters for program and project formulation and budgeting, and officials in the executive and legislative branches for program and project funding. Mission and project design andt building depend on information such as spacecraft and instrument performance, whereas mission testing depends on information about the operational environment that has been obtained from other missions.
