Most science fiction stories are bout tall, square-jawed adventurers exploring the galaxy and singlehandedly vanquishing the alien foe. What about the people who perform the unexciting "blue collar" jobs that make the voyages possible?
A being, of indeterminate gender, maintains a ship's waste treatment system. A female asteroid miner has a unique companion. It is an alien-constructed being, made from human sperm. It looks exactly like a human, but, on the inside, there is no mind or personality. Imagine an episode of the TV show "The Deadliest Catch" moved to the asteroid belt.
On Titan, a human miner is caught in the conveyor belt that carries the pieces of rock out of the mine, and deposits them in a giant pile, in open vacuum. A trio of women spens their days walking on top of a domed city, patching up holes and cracks in the dome. Another story takes place on an Earth that has run out of energy. The only working motor vehicles are those that people build themselves. There is also a news story about the hazards involved in being part of the crew building a space station in orbit.
This is a strong, well done group of stories about a not-well-known part of society. There is a good variety of stories, from lesser-known authors, that are well worth reading
