Under Study

Missions begin with a study phase during which the key science objectives of the mission are identified, and designs for spacecraft and instruments are analyzed. Study teams are constituted to define measurement and mission elements and deliver achievable objectives with a specific cost and scope. Study teams are managed by a Project scientist, a Program Executive at NASA Headquarters, and a Program office.
