3. If I remember correctly, Stephen Baxter's novel Moonseed (1998) explores this question and answers yes, it could maintain an atmosphere sufficient to support human life on the surface for a couple of hundred years before it attrited away. Hardly definitive, but he's no slouch when it comes to research. Share.
The atmosphere is composed of 78% 78 % Nitrogen, 21% 21 % Oxygen, 1% 1 % Argon and then the rest is traces of other gas. Such as Helium, Carbon Dioxide, Carbon Monoxide, Methane, Krypton, etc. Which of these gasses should you keep, and which should you drop when creating a breathable atmosphere on the Moon?
The mass of Titan is 1,345 · 10 23 kg, but the mass of the Moon is 7,349 · 10 22 kg. The gravity at the surface is 1,35 m/s² for Titan and 1,62 m/s² for the the Moon. But the surface temperatures are very different, 94 K for Titan but the mean surface temperature of the Moon is 218 K and the peak about 300 K.
Apparently there isn't much xenon, from any source, in the Moon's "atmosphere". I put "atmosphere" in quotation marks because it's actually an exosphere, where the distance an atom or molecule travels between collisions with other atoms or molecules is greater than the scale height. In the Moon's case, it is much greater.
For example, googling for "moon temperature" finds: Daytime on one side of the moon lasts about 13 and a half days, followed by 13 and a half nights of darkness. When sunlight hits the moon's surface, the temperature can reach 260 degrees Fahrenheit (127 degrees Celsius). When the sun goes down, temperatures can dip to minus 280 F (minus 173 C)
Earth's gravity is 9.78 m/s². As a comparison, Jupiter's gravity is 24.79 m/s² and Titan's gravity is 1.352 m/s². Earth's atmosphere is, at sea level, 1 standard atmosphere or 101.3 kPa or 14.7 psi compared to Mars's average which is about 0.006 standard atmosphere or 600 Pa or 0.087 psi and Venus's average which is about 9.2 mPa or 1,330 psi.
The moon has no atmosphere, so only the dust directly in the path of the rocket exhaust will be disturbed. This is unlike Earth, where the exhaust would drag along the surrounding air, creating a much larger area of influence. So anyplace that's even a bit shielded from the exhaust would remain undisturbed.
If the Moon had an atmosphere, it would lose it in some tens of millions of years(*). This is why any atmosphere it once had is long gone, but this would be enough for us and our shorter time scale, which is only some thousands of years in the most optimistic sense. Nitrogen is rare on the Moon, but it is not really needed.
Hence every photograph has a characteristically inky and plain black backdrop. An example is this image: However, for the astronauts actually on the Moon, all the stars and galaxies should have been perfectly visible. In fact, they should have been the most clearly visible stars seen by human eyes, since they were further out of Earth's ...
9. On Earth if you need to collect gases you can use passive hood exhaust under a fusion (convection), or just under hot liquid, or use vacuum pumps for catch gases together with air. In the space or on Moon there are no convection and atmosphere so we can not use these methods. What is best practices for aggregate gas in open space and on Moon ...
