The committee emphasizes that the success of future New Frontiers missions after the currently planned announcement of opportunity requires that new ideas and innovations be constantly generated, and that they go through successive rounds of review, evaluation, and critique in order to become stronger and more competitive.
Recommendation 3: NASA should consider mission options outside the three remaining and five additional medium-size missions described in the decadal survey that are spurred by major scientific and technological developments made since the decadal survey. As with any New Frontiers mission, these proposals must offer the potential to dramatically advance fundamental scientific goals of the decadal survey and should accomplish scientific investigations well beyond the scope of the smaller Discovery Program. Both mission-enabling technological advances or novel applications of current technology could be considered. However, NASA should limit its choices to the eight specific candidate missions unless a highly compelling argument can be made for an outside proposal.
