and supporting activities. But as Chapter 1 has shown, very little of the recommended NASA priorities from the decadal survey will be realized during the period covered by the survey. Mission cost growth, reordering of survey mission priorities, and unrealized budget assumptions have delayed or deferred nearly all of the NASA missions recommended in the survey. Some of these factors were largely outside NASA’s control, but as the assessments in Chapter 2 detail, many were driven by subsequent NASA decisions about mission science content, mission size, and mission sequence. Overcoming these challenges, as well as other key issues like launch vehicle availability, will be critical if NASA is to realize more of the decadal survey’s priorities over the next 5 years and to succeed in its solar and space physics research enterprise over the long term. Chapter 3 provides recommendations about how NASA can better fulfill the 2003 decadal survey and improve future decadal surveys in solar and space physics.
