Voisitko täsmentää tätä tuon kaasukehän tärkeyden osalta ?
Uteliaisuuttani kyselen, kun minulla on ollut vähän toisenlainen käsitys tilanteesta.
Veden tuotannon osalta, on se toki helpompaa kuin Kuussa.

Atmosphere
Mars has an atmosphere. It’s not really a great atmosphere, but at least it is one. It is mostly carbon dioxide, which is great for plants, but really sucks for us humans. The atmosphere allows wind to blow, which helps to equalize the day-to-night temperature differences—but causes a lot of dust to move around, too.
The atmosphere also means that we can pressurize domes and structures using air from outside.
The moon, on the other hand, has almost no atmosphere. NASA’s website
explains, “At sea level on Earth, we breathe in an atmosphere where each cubic centimeter contains 10,000,000,000,000,000,000 molecules; by comparison the lunar atmosphere has less than 1,000,000 molecules in the same volume.” Since the moon has so little atmosphere, any wind can’t really move heat from the hot day side to the cold night side.
Mars’s atmosphere could also stop a bunch of harmful EUV and energetic particles from the sun. This would prevent you from frying if you went outside. The moon doesn’t really have anything to block you from getting zapped (technical term). Really, you would have to definitely live in caves on the moon, but on Mars, it might be possible to live above-ground. You would still get a fair bit of radiation exposure, though. Really, neither of them is great from a radiation standpoint, but if one had to choose, Mars is better.
An interesting historical fact is that during 1972, when there were a couple of moon landings,
there were a lot of solar radiation events. One was bad enough that it could have killed all of the astronauts on the moon if there had been any.
