A European extravehicular activity (EVA) system baseline similar to the STS baseline was derived from analysis of Hermes/Columbus and other ESA manned missions. The ESA suit, however, uses single walled laminate materials. Equipment heat dissipations are collected via cold plates. The sublimator is augmented by a heat storage unit. Primary oxygen storage uses a high pressure nonrechargeable system. The prime mover consists of a separate axial fan, paristaltic pump, and high speed rotary separator. The EVA information/communication module (EICM) uses a digital communications system. The EICM offers a more sophisticated automatic checkout and data display capability than the STS system. The technology assessment indicates that the development of the defined European EVA system lies within the capabilities of European industry although potentially technology transfer from the USA could have substantial benefits.
