  • Any volume is large enough for rain or fog. Humidity buildup (rain) is a concern in spacecraft design, and was one of the reasons (too much rain) that caused one proposed Martian settlement to fail, according to simulations.
  • You shouldn't need to worry if you have enough water.
  • However, aerogel is porous. You'll want something like mylar coating inside the dome to keep the water and air from escaping.

  • You shouldn't need to worry about weather - if you have enough water.

Any volume is large enough for rain or fog. Humidity buildup (rain) is a concern in spacecraft design, and was one of the reasons (too much rain) that caused one proposed Martian settlement to fail, according to simulations.

You shouldn't need to worry if you have enough water.

However, aerogel is porous. You'll want something like mylar coating inside the dome to keep the water and air from escaping.
