Are such power sources available? This study says no, not yet--and points the way toward the kind of energy research and development that is needed to power SDI. Advanced Power Sources for Space Missions presents a comprehensive and objective view of SDI's unprecedented power requirements and the opportunities we have to meet them in a cost-effective manner. 606 $aHigh technology 606 $aSpace vehicles$xNuclear power plants 606 $aSpace vehicles$xAuxiliary power supply 606 $aSpace vehicles$xPropulsion systems 615 0$aHigh technology. 615 0$aSpace vehicles$xNuclear power plants. 615 0$aSpace vehicles$xAuxiliary power supply. 615 0$aSpace vehicles$xPropulsion systems. 676 $a629.47/44 701 $aGavin$b Joseph G$01807056 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910957774803321 996 $aAdvanced power sources for space missions$94356566 997 $aUNINA
