Long term exposure to lack of gravity wrecks havoc on human bodies, causing everything from vision impairment to bone density loss. The paper’s authors’ explicitly list 5 that their space habitat design was trying to address: However, we are now one step closer to doing so with the release of a paper from a team at Texas A&M that describes a way to build an expandable space habitat of concentric cylinders that can house up to 8000 people.Īny habitat that houses that many people will have to deal with some major downsides of living in space. Unfortunately, we are still a very long way from building anything like a fully sized habitat. These could be located anywhere in the solar system, could be of any size that material science allows, and have different characteristics, such as temperature, climate, gravity, and even lengths of day. The alternative is to build our own habitats. That approach comes with some major disadvantages, including dealing with toxic soils, clingy dust, and gravity wells. The one more commonly portrayed is of us colonizing other celestial bodies such as the Moon and Mars. There are two main approaches that humanity can take to living in space.
