Space solar power - The transportation challenge

Abstract

The status of space transportation systems analyses referable to the SPS (solar power satellite) is reviewed briefly. Propulsion systems (including magnetoplasmadynamic) and booster arrangements for the SPS mission and variants in recovery arrangements (including winged recovery) are summarized, along with proposals for production of SPS components in space from lunar and asteroidal materials. Transportation of the pilot plant into low circumterrestrial orbit or high geosynchronous orbit, transfers between those orbits, and construction of a large work bench structure (orbital construction demonstration article - OCDA) in low earth orbit are discussed.
