Deriving technology needs from measurement strategies

The Earth-Sun System Division in the Science Missions Directorate of NASA has seven science focus areas, which are oriented to gathering space-based data used in the decision-making process for National policy on the Earth environment. Science roadmaps, derived from the NASA strategic planning process, serve as the vehicle for deriving measurement strategies and remote sensing requirements. The technology requirements (instrument, information systems, and platform) are developed to fit the schedule and cost assessed against the proposed mission need dates. This paper will discuss and show the current state of this process.
