Table 2.1. (Cont'd) Group Effects Activities Involved State of Knowledge References Space Workers (Cont'd) Emergency Medical/Dental Problems Orbital Transfer, Space Construction, Space Operat ion • No data available on projected occurrence rate for SPS. High Acceleration/ Deceleration Effects Launch, Recovery e Some data available from other space program activities. Extra Vehicular Activity Hazards Accidental Injury/ Fatality Space Construction, Space Operation • No data available on projected SPS occurrence. Extended Confinement Psychological stress Space Construction, Space Operation • Some studies on confinement under other circumstances. Thermal Extremes Hypothermia Injury/fatality Space Construction, Space Operation • Data on effects on earth available. Plasma Arcing Space Construction, Space Operation • No data available. High Intensity Electromagnetic Field Exposure Space Operation • Effects to be investigated. Ecology Air Pollution Ecological Ef feets Mining, Manufacturing, Construction, Launch, Transport • Gross effects of selected pollutants are known and documented. Dose response of vegetation is poorly understood. Long term low dose, widespread ecological effects not known. 2.8.26 Water Pollution Ecological Effects Mining, Manufacturing, Construct ion • Effects of many pollutants on aquatic ecosystems well known; may range from insignificant to severe. 2.8.23 2.8.24 Solid Waste Ecological Mining, Manufacturing • Gross effects known and documented. Includes leaching of toxic chemicals from waste piles. 2.8.22 Land Use Mining, Manufacturing, Construction, Launch Sites, Transport, Rectenna Siting, Power Distribution System • Land use changes known and documented for selected activities. Some constraint predictions dependent on system definition. Wildlife attraction to rectenna site appears probable for some species but no documentation exists. 2.8.25 Noise Launch, Recovery • Very little information concerning effects on animals; information on ecological impact is lacking. 2.8.9 Reflected Light Plant & animal cycles changed by reflected light Space Operations • Much is known about influence of light on biological cycles. Current SPS system definition information insufficient to predict effect. 2.8.28 High Intensity Electromagnetic Field Exposure Ground Station Operation • Effects to be investigated.
