Here's a new SF market, with emphasis on near-future. So, would the moon be considered off-world? I find it interesting that with the emphasis being so often on short and tight stories, stories under 2000 words are a hard sell to this market. I don't think the implication is to necessarily meander, but some readers do like to linger in an environment.
With resources like this on the web, why in the world would someone like me offer up writing advice? Oh yeah, because I can't seem to shut up. I think that may be a common flaw, or maybe it's an advantage, or both, of people who are writers.
