Ganymede

I gave a short story to one of my students a couple of weeks ago, and he quite enjoyed it. He asked if I normally wrote SF, to which I replied that I couldn't really pin down what I usually wrote because it has elements of everything in it. So he requested me to write him an SF story. He mentioned liking Paol Anderson's Ganymede books, which I've never read (the front cover of the SF Masterworks series always put me off). Anyway, it got me thinking about Ganymede, which ties in with something else I was writing, connected to Jupiter.

I need a magazine which accepts 5000+ word stories on a slightly SF theme. I sent the story off to one in England but they didn't want it. So it needs to go somewhere else. Ideas anyone?

I'm gonna look at Moleskine artwork until it's time to go swimming...
