Tharshan Maheswaran and Sebastian Fix from the University of Stuttgart, Institute of Space Systems describe a roadmap for the development, construction and transport of an international planetary sun shield (IPSS) at the Lagrange point 1 in 2021, which will also be a photovoltaic plant could be. Here, too, as with Hermann Oberth, production on the Moon, the use of an electromagnetic Moon slingshot (lunar coilgun) and the transport of the components from the Moon to the Lagrange point 1 between the Earth and the Sun are discussed by means of electric spaceships (alternatively with sun sails) assumed. The authors refer to the many international activities and the chance to put the sunlight shield into operation by 2060.
