This brief explores the biological effects of long-term radiation on astronauts in deep space. As missions progress beyond Earth's orbit and away from the protection of its magnetic shielding, astronauts risk constant exposure to higher levels of galactic cosmic rays and solar particle events. The text concisely addresses the full spectrum of biomedical consequences from exposure to space radiation and goes on to present possible ways to mitigate such dangers and protect astronauts within the limitations of existing technologies.

This study, commissioned by the National Aeronautics and Space Administration (NASA), examines the role of robotic exploration missions in assessing the risks to the first human missions to Mars. Only those hazards arising from exposure to environmental, chemical, and biological agents on the planet are assessed. To ensure that it was including all previously identified hazards in its study, the Committee on Precursor Measurements Necessary to Support Human Operations on the Surface of Mars referred to the most recent report from NASA's Mars Exploration Program/ Payload Analysis Group (MEPAG) (Greeley, 2001). The committee concluded that the requirements identified in the present NRC report are indeed the only ones essential for NASA to pursue in order to mitigate potential hazards to the first human missions to Mars.

This chapter deals with some key topics of orbital safety. It starts with an overview of the issue of space traffic control and space situational awareness, and then proceeds to address conjunction analyses and collision avoidance maneuvers (CAM), including for the International Space Station. Another kind of collision risk discussed is the jettison of discarded hardware. The chapter then covers rendezvous and docking/berthing operations. Collision safety risks, their causes and consequences, and the measures for protection are discussed in detail. The chapter also covers the issues of space vehicles charging and contamination hazards, including the shock hazard for astronauts involved in extravehicular activities. Finally, the chapter presents end-of life mitigation measures and techniques for space debris removal, such as space tugs, drag devices and electrodynamic propulsion.
