Maintain atmosphere on moon using global warming So, a neat thing, depending on how you look at it, about greenhouse gases is that while it's causing a raise in temperature near the surface it actually makes the upper parts of the atmosphere decrease in temperature. Venus is a good example of this. Now on another note, atmospheric escape depends s... (more) |

Rocky core, internal ocean, ice crust, external ocean So I writing a story where we terraform Titan using super heavy green house gases where the lower part of the atmosphere near the surface stays warmer. Because of this, a portion of the moon's icy crust melts leaving the planet with an ocean sitting on top of an icy crust, with another ocean below th... (more) |

Build a better cold trap What I'm doing is trying to find a way to create an atmospheric cold trap that will maintain a temperature of approximately −200 degrees Celsius (−328 Fahrenheit). According to Wikipedia In astronomy, a cold trap is a close to the surface layer of the atmosphere that is substantially colder th... (more) |

Dyson-Harrop to power an ion engine? With all the interest in VASIMR and the idea of getting to Mars in 39 days, the biggest challenge I can see is having a power source that is strong and light enough to make that possible. So I was thinking, shouldn't a Dyson-Harrop satellite built into some hypothetical spaceship be able to easily pr... (more) |

Using temperature to contain an atmosphere? So, I was looking at the temperature variations in Earth's atmosphere and noticed that it gets extremely cold in some of the upper portions. So I was wondering, could a low gravity world hold onto an atmosphere and have earthlike surface temperatures if there was some kind of handwave particles/super... (more) |

Holding in an atmosphere primarily using a magnetic field Assuming it was possible to create an artificial magnetic shield on the moon, would it be possible that a sufficiently powerful field could hold onto an atmosphere despite the low gravity. Thanks (more) |
