... Understanding the risks of radiation exposure and interactions, cumulative biological effects in long-term microgravity environments, and effects on human behavior and performance, as well as long-term verification of hardware and biological countermeasures and life-cycle testing, will all require the ISS as the only available capability for tended experiments in a free-fall environment for periods of time that approximate a Mars outpost mission. As noted previously, the panel lacked both the time and the necessary data to attempt a comprehensive assessment of the diverse research issues that have to be addressed to enable NASA's human exploration plans.

... Previous reports have emphasized the importance of areas of fundamental biological and microgravity research in the development of new technologies and the mitigation of space-induced risks to human health and performance both during and after long-term spaceflight.1-3 Chapters 4 and 5 of the present report summarize several priority areas of fundamental biomedical and physical science research that are crucial to achieving acceptable levels of risk in spaceflight beyond low Earth orbit. The panel fears that loss of these programs may limit or impede development of such technologies and biological countermeasures and it notes that, once lost, neither the necessary research infrastructures nor the necessary communities of scientific investigators can survive or be easily replaced.
