As part of the Vision for Space Exploration (VSE), NASA is planning for humans to revisit the Moon and someday go to Mars. An important consideration in this effort is protection against the exposure to space radiation. That radiation might result in severe long-term health consequences for astronauts on such missions if they are not adequately shielded. To help with these concerns, NASA asked the NRC to further the understanding of the risks of space radiation, to evaluate radiation shielding requirements, and recommend a strategic plan for developing appropriate mitigation capabilities. This book presents an assessment of current knowledge of the radiation environment; an examination of the effects of radiation on biological systems and mission equipment; an analysis of current plans for radiation protection; and a strategy for mitigating the risks to VSE astronauts.

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.

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.
