Note: From Introduction: "The question for future exploration is whether a continued reliance of robotic space probes will be sufficient to meet the core objectives of astrobiology or whether the search for life in the Universe would benefit from a renewed, and greatly expanded, program of human exploration beyond low Earth orbit (LEO)." Potential benefits supporting the latter approach are given in the article.
