Large-Class Spacecraft Missions Large, or flagship, spacecraft missions are EUROPA CLIPPER selected by NASA to fill specific strategic needs. The second-highest-priority large mission Decadal surveys play a key role in defining the identified in the decadal survey published science case for the initiation of new flagship in 2012 was an orbiter to conduct a detailed missions.

NEW FRONTIERS PROGRAM in that proposals are restricted to addressing NASA's New Frontiers missions fill the a half dozen or so focused science goals middle ground between the small-class identified in decadal surveys. New Frontiers Discovery missions and larger, less frequent missions, while complex, are intended to go flagship missions.

Such research and analysis activities not only extract the maximum scientific return for individual missions but also develop new hypotheses, create the scientific foundations for future exploration activities, support laboratory studies, build theoretical models, FIGURE 10 Careful analysis is essential for extracting the maximum undertake geologic mapping, and train the next scientific return from data collected by spacecraft missions.

as "Restricted Earth Return" and must be strictly contained until any potential biological Astromaterials -- for example, meteorites, hazard has been thoroughly assessed. Planning cosmic dust collected by special high-altitude for a facility to house martian samples under aircraft, or samples returned to Earth by strict containment is currently under way.
