EVA missions, beginning with the Space Shuttle and continuing through the 80's and 90's are evaluated in an evolutionary perspective. The projected large space structures, to be assembled in orbit, will require EVA for their construction. Various parameters of EVA are analyzed, including: EVA tasks and system requirements, system pressurization level, and radiation protection. Existing technology and already proven EVA techniques are considered adequate for future EVA missions, with some modifications. Space suit pressure, for example, can be increased from 4 to 8 psi, depending on ambient pressure in the spacecraft. Radiation shielding might have to be improved for higher altitude LEO's. Also, new restraint systems will probably be required for the more complicated EVA tasks.
