Hermann Oberth . Der Weltraumspiegel

 

 

The space mirror

"Since I first described the large space mirror in my book ’Die Rakete zu den Planetenräumen‘ (The Rocket to the Planetary Spaces) in 1923, much has been said and written about it, much of it correct and even more of it incorrect."

"It would be more obvious and realistic to exploit the possibility of artificially shading planets close to the sun. For this purpose, huge sunshades would be built, similar in design to my space mirror, but of course much larger. [...] On the moons of the outer planets, large space mirrors could be used to ensure tolerable temperatures. […] Even our own moon could be made habitable on a large scale. It would be shaded by sunshades during the day and illuminated by sun mirrors at night to create a shorter day-night cycle."

"Based on current plans and possibilities, a mirror with a diameter of 100 kilometres would cost around 1,000 billion marks."
