Do the buildings contain an airlock, or would you have to wear spacesuits inside them?Better images of the permanent lunar habitat proposal from Huazhong University of Science and Technology. The walls of the egg-shaped buildings are constructed in situ by 3D printing robots, using mostly lunar soil (80%) and binders. The structure also features a soft air-filled inner layer (like an airbag) designed to mitigate the effects of moonquakes while also serving as insulation.
I think it is certain without being explicitly stated that there is airlock for such habitat. Not-having airlock would only be feasible for limited number of exit/entry due to lost of air of the whole volum.Do the buildings contain an airlock, or would you have to wear spacesuits inside them?
And as air-tight seal because the outter shell aren't air-tight.The structure also features a soft air-filled inner layer (like an airbag) designed to mitigate the effects of moonquakes while also serving as insulation.
