I don't know if you're ripping it off, but it is awfully similar.
My advice: Don't just change the name of the story, change the name of the colony, too. You said it was codenamed "Fortuna", just make it the name of the colony and name the story "Fields of Fortuna" instead.
Also, you'll have to make the story and characters very different than in the movie so you can get away with the similarity of the worlds.
I know your plight. I also placed a lot of effort into a story and they made a very similar movie
