How about inflating them with water, and then living inside another air inflated bubble inside? Like a giant cell. Radiation shielding, micrometeorite shielding, plus water is pretty important too. Other gear can float inside the water behind their own membranes like organelles, some use the water to radiate heat away, some use water for other things like making macronutrients (carbs, fibre, protein, & fat), or processing waste.
- jpatokal 11y agoAnd where are you proposing to get the necessary swimming-pool-like volumes of water? Shipped from the Earth at ~$20,000/kg?
- jp555 11y agoThat's only the cost if you use disposable rockets. About the same cost/kg of flying if you're throwing away the 777 after one flight. Reusable rockets are magnitudes cheaper per launch. Or there's robotic in-situ water mining - Ceres has a shallow gravity well and probably has as much water as Earth. Easy? No, but space is always going to be hard.

- gozur88 11y agoI've seen people propose this before, and it's always bothered me, because when they say they're "storing" water it suggests the water will be there until the needed for some other purpose. But if you're using water for radiation shielding and you then dedicate it to some other purpose, you no longer have radiation shielding.
