摘 要：This letter report is the first in a series of five reports. The committee will provide an independent review of the more than 30 evidence reports that NASA has compiled on human health risks for long-duration and exploration spaceflights. In 2008, NASA asked the IOM to assess the process for developing the evidence reports.1 The resulting report, Review of NASAs Human Research Program Evidence Books: A Letter Report, provided an initial and brief review of the evidence reports. This letter report builds on the work of the 2008 IOM report and examines three evidence reports: 1. Risk of Injury from Dynamic Loads; 2. Risk of Clinically Relevant Unpredicted Effects of Medication; and 3. Risk of Spaceflight-Induced Intracranial Hypertension and Visual Alterations.
