What spaceship fuel to use on Ceres? For spaceships working on or near Ceres, what would be the best option for locally produced fuels? Let's assume that there's plenty of water ice available, and other chemicals as long as its plausibly realistic. There is lots of electricity due to fusion reactors on the surface. Spaceships use batte... (more) |

Forming a dust ring around asteroid Ceres Is it possible, due to asteroid mining activities, for a space-fairing civilization to produce a dust ring around a very large asteroid (Ceres)? In my world, there is a lot of ore processing being carried out in low Ceres orbit. Mining equipment is smashing rocks to gravel, and a lot of dust is esca... (more) |

What sort of atmosphere would develop around an asteroid colony? In the not too distant future, mankind has established several mining bases on Ceres. There are a lot of spaceships which come and go. Large mining machines are chewing up the interior for resources. Ceres has become a busy frontier trading station, with most colonists living and working underground.... (more) |

What's it sound like as the airlock is depressurized? I have a scene where an alarm is sounding in an airlock, as the pressure is lowered from normal atmospheric pressure to vacuum (takes a few minutes). How would this alarm sound to an unprotected person unlucky enough to be in the airlock? What would this also sound like to someone inside a pressuri... (more) |

Flight paths in orbit around Ceres? In my sci-fi world, mankind has begun colonization of the large asteroid Ceres. It's a mining hub, with a lot of cargo vessels transporting things in and out. Hydrogen peroxide fuel is cheap and plentiful around Ceres, and the gravity well very shallow, so the kind of fuel efficient rendezvous moves... (more) |

Keeping a retro style to sci-fi spaceships? In my sci-fi world, mankind has begun colonization of the large asteroid Ceres. There are several established towns on the surface, but most of the population live underground in icy/rocky caves. The major industry is mining and exporting water-ice. Ceres is undergoing a rapid transformation from pri... (more) |

Spaceship fuel on Europa What would make a good propulsion source for small engines and manouvering thrusters for spacecraft vehicles on Europa (moon of Jupiter), both for near-surface operations (vacuum) and in caves beneath the ice (low or medium pressure)? I am only interested in spacescraft thruster propulsion systems, ... (more) |

How to design a zero-g nuclear reactor? My worldbuilding involves a reasonably near-future, high-realism space station research outpost, and I'd like it to be powered by a nuclear reactor. However, I need as much detail on the actual reactor design as possible. (Also, if its totally impractical, should I move to fuel cells?) Are any of to... (more) |

Space station debris What happens to small pieces of debris left floating around inside a derelict space station? My space station had 100 people aboard, and due to sabotage, it decompressed and was abandoned. Inside, there are thousands of small items, like screws, papers, tools, usb memory sticks, forks, and so on. ... (more) |

Designing a binary asteroid pair I am interested in building a little world involving a very realistic asteroid pair, orbiting each other, and would really appreciate some help with numbers and science for this. I would like two largish asteroids orbiting each other as close as is feasible.. (ideally I'd like a distance of up to 15k... (more) |

Communication and Navigation for space flight on Europa Considering the rather hostile radiation environment on Europa, what communication and navigation systems might be used with near-future manned spacecraft? What would the ranges and features of this equipment be? I would be most interested to hear about the possible functionality of existing system... (more) |

Building materials on Europa What would colonists building a base on Europa use for building materials? I am interested in habitats in three locations: on or just under the surface bolted onto the underside of the ice sheet rooms hollowed out from the lowest level of the ice sheet Can metals or other building material be ex...

Establishing an under-ice base on Europa - ice drilling/melting? If life were discovered in the supposed ocean on Europa, it would be a popular destination for scientists and researchers. I am curious as to what life on Europa would be like, in terms of engineering and building a sustainable habitat. First, to reach the ocean, is it more practical to melt down th... (more) |
