To better understand the processes that connect the Earth environment to the Sun, NASA's Living With a Star program must address questions that cut across traditional science disciplines. To meet this challenge, the Targeted Research and Technology component of Living With a Star has developed an innovative strategy to focus research on the most complex science targets. The targets are drawn up each year by a panel of senior scientists. These targets are then publicized, and individual researchers can propose solutions. NASA then selects teams of researchers through a peer-review process for each targeted effort. This contrasts with other NASA programs in which individual and independent programs are selected for study.
