The solar power satellite (SPS) concept is an elegant solution to the challenge of providing large-scale energy for humanity a large platform, positioned in space in a high Earth orbit, continuously collects and converts solar energy into electricity. SPS-ALPHA is composed of a large number of small modules, which enables the modularity and lower cost of machining/space transport. Until now two options of SPS-ALPHA have been proposed, the Mark-I version (sigmoid-curve-based shape) and the Mark-II version (conical shape). The current
