List out some of the negative issues of space stations.
The space stations have numerous negative impacts that limit the long-term habitability of the astronauts. They have very low recycling rates, relatively high radiation levels and lack of gravity. These problems cause discomfort and long-term health problems. In the case of solar flares, all current habitats are protected by the Earth's magnetic field. Future space habitats may attempt to address these issues, and could be intended for long-term occupation. Some designs might even accommodate large numbers of people.
