ESA European Aspects of SPS

1-1-7 The Rockwell SPS-Concept 1977/78 Characteristics: After delivery to LEO by HLLV's, dedicated electrical orbital transfer vehicles woult take the raw materials to GEO where the SPS is constructed by a crew of 500 or more. The GaAlAs cells ( silicon might be another option ) would operate at 125 °C. At this temperatures the cells will regenerate from the particle radiation damages ( self-annealing ). The construction philosophy of this SPS-concept is more sophisticated and requires some technology advancements.
