Public domain German science fiction novel translated to English

Bradley Hall (editor of the Pirate Party's No Safe Harbor book) says, I've been translating old public domain German-language books that I have been finding on Gutenberg.org. So far I have done two – a book of Japanese Fairy Tales and an old never-before-translated science fiction novel from 1909. The science fiction novel, The Red Comet (or Der Rote Komet), is interesting because it takes place in the year 2439, there's a comet on its way to crash upon the Earth. A comet. Not a meteor. Also, the most noteworthy invention is a special camera created by Romulus Futurus (now that's a Sci-Fi name)."
