John W. Campbell 
Moon is Hell [EPUB ebook] 

John W. Campbell was the man who made modern science fiction what it is today. As editor of Astounding Stories (later Analog), Campbell brought into the field such all-time greats as Asimov, Heinlein, Sturgeon and many others, while his own writing blazed new trails in science fiction reading pleasure.The Moon is Hell is this great writer-editor’s vision of the first men on the moon — written 18 years before Neil Armstrong made history. This is the story of the American space programme — not as it happened, but as it might have been.
