Thanks to all who entered. We asked you what your favorite hard SF story was, and you...had some. Here are our four winners of Orbital Cloud by Taiyo Fujii!

First is Mike D. for his deep cut answer Hayford Peirce’s novelette “High Yield Bond” (1975). Just the reference deserves a book!

Jmitsu wrote a sonnet about Biogenesis by Tatsuaki Ishiguro. A good one!

We've often said that if you liked The Martian, you'll love the positive science fiction of Taiyo Fujii, and now Pilar will prove it for us.

Finally, Jeremiah Tolbert wins for his mention of black holes, the most mind-bending and space-bending bit of hard SF furniture (and our astounding universe.)

Congratulations to all the winners!
