Speed of elevator on rotating wheel space station Assuming a passenger was sitting in an elevator in a rotating wheel space station, as depicted in the movie 2001:A Space Odyssey and based on this question Elevator on rotating wheel space station, would there be any obvious structural or physiological limitations on how quickly an elevator could mo...

Would the Earth appear to be spinning off center when viewed from geostationary orbit? In 2001:A Space Odyssey, from Space Station V the Earth appears to be spinning around a center that is near the edge of the planet. Phone call from space station scene If the same station (300 meters in diameter) was in a geostationary orbit (35,786 km from the Earth), would the apparent center of s... (more) |

What rare elements would be most needed in building a space station beyond the Earth? If people were attempting to build a space station beyond the Hill Sphere, (outside of the area where Earth's gravity dominates), and wanted to mine the raw materials for the station from dwarf planets, comets, and asteroids, what rare earth element or mineral would they mostly likely be looking for ...

Rare Earth Elements in the outer solar system If a space station were to be built in the outer solar system, is there an asteroid beyond Jupiter with a ratio of rare earth elements high enough to make it worthwhile to mine for the rare earth elements, to supply this space station with those materials it needed?

Spaceplane simulating winged flight in the vacuum of space? If a spaceplane were to try to simulate the look of aerial flight in the vacuum, would it be difficult or easy for the pilot to manually simulate aerial maneuvers, using just a contemporary reaction control system, and make no use a computer. I'm imagining a flight demonstration squadron in outer sp... (more) |

Cooling the interior of a spacecraft to below the freezing point I understand the Apollo 13 CM got down to 39°F after it was powered down following the explosion in the oxygen tank. Could the interior of the ISS be cooled (for more than 12 hours) to below 32°F while keeping the atmospheric composition and pressure unchanged from standard values, with the equip... (more) |

How to determine port and starboard on a rotating wheel space station? The ISS uses port and starboard to differentiate between the two sides of the station. (The Harmony node photographed after it was attached to its temporary location on the International Space Station) Would forward always be in the direction the ship is rotating, and from there port and starboard...

Could a single highly elliptic orbit be used to redirect to another planet? I'm modeling this on the Voyager 2 flight path. I want to have this flight at this particular time, and not wait for a more advantageous launch window. Based on this orbital configuration (1st image below) the day a spacecraft leaves Earth, could a spacecraft slingshot around Jupiter, enter a sing... (more) |

Where should a runway for a spaceplane be located? If a spaceplane like the Rockwell X-30 existed and was flying to a location in geostationary orbit, would it be substantially more efficient to take off from a runaway at the equator, or would it not make that much of a difference? This question is not about craft designed and powered solely by roc... (more) |

Elevator on rotating wheel space station Is there any reason an elevator, moving from the central hub to the outer ring, would not function on a rotating wheel space station with artificial gravity? Any parameter of the radius or rotation rate of the station is fine. I don't have any particular G force in the outer ring in mind. Any level... (more) |

Zero G area on rotating wheel space station If I needed a large area for zero-G training, is there any place to put it on a rotating wheel space station if the hub was needed for docking of spacecraft? I wanted a place on the station that people could easily go to, hang out and relax, that would be zero G. I wanted it to be a place where th... (more) |

Launching spaceships from the outer edge of a rotating wheel space station Based on Docking on the outer edge of a rotating wheel space station would it be impractical to launch ships off of the outer edge of a rotating wheel space station? Whether launching the ships along the tangent, or along the same plane as the tangent, just in a different direction? (more) |

Docking on the outer edge of a rotating wheel space station Assuming such a space station needed to have its central hub not used for docking spacecraft, would it be plausible for a spacecraft to dock on the outer edge of a rotating wheel if the ship approached the station on a tangent to the outer edge, in the direction of rotation? I'm assuming a drone shi... (more) |

Inner ring on rotating wheel space station? Could Space Station V, from 2001: A Space Odyssey have an inner ring? Would the inner ring have a different G-force if the inner ring was halfway between the outer ring and the hub. Would there be any limitations on this because of stresses on the structure. Space Station V Diameter 300 m (984 ft... (more) |

Solar panels on rotating wheel space stations What would be the best configuration of solar panels on a rotating wheel space station? I am thinking about Space Station V design and dimensions. Space Station V comes from 2001: A Space Odyssey. Space Station V was the largest orbital structure ever built as of 2001. It is a large, internatio... (more) |

Launch window from heliopause to Earth? Assuming an ion propulsion ship was leaving station in an orbit at the radius of the heliopause, and the most direct trajectory takes 18 months to get to Earth, would there be a launch window or could the ship leave at any time? I was figuring with that distance, and time to alter the flight path, a... (more) |

Could a rotating ring space station have a bolo-like extension? If the outer ring of a rotating space station was producing the equivalent to 1G, but a higher G was needed could in small modules, could a bolo-like attachment be included with the ring to accomplish this? In the illustration below of a bolo arrangement, artificial gravity is achieved by having two... (more) |

Could there be something like aerobatic smoke trails in the vacuum of space? Whether exhaust from a solid rocket engine, or something released by spaceships in flight (like aerobatic smoke in the atmosphere), could extended trails behind a ship be created that would not dissipate in the vacuum of space? Could a trail be formed that a person close enough to see the ship with ... (more) |
