Assessment of programs in space biology and medicine

Over the past 30 or more years, the National Research Council Space Studies Board and its various committees have published hundreds of recommendations concerning life sciences research. Several particularly noteworthy themes appear consistently: (1) Balance - the need for a well-balanced research program in terms of ground versus flight, basic versus clinical, and internal versus extramural; (2) Excellence - because of the extremely limited number of flight opportunities (as well as their associated relative costs), the need for absolute excellence in the research that is conducted, in terms of topic, protocol, and investigator, and (3) Facilities - the single most important facility for life sciences research in space, an on-board, variable force centrifuge. In this first assessment report, the Committee on Space Biology and Medicine emphasizes that these long-standing themes remain as essential today as when first articulated. On the brink of the twenty-first century, the nation is contemplating the goal of human space exploration; consequently, the themes bear repeating. Each is a critical component of what will be necessary to successfully achieve such a goal
