Meta: ISFDB. First published May 2012 in Lightspeed. I’ve read it in The Year’s Best Science Fiction: Thirtieth Annual Collection
Four aging explorers accept a hazardous mission to Jupiter’s moon Callisto. Their goal is to establish an ice-mining station to feed the needs of the Shell Cities. The story’s background reads like a teaser for a new novel – it is mostly left unexplained.
Old women in spacesuites (remembering me of Scalzi’s Old Man’s War), zombie-mechs, consistent technology mostly action: this is popcorn Hard SF.
