Inflatable space habitat upper
A hypothetical inflatable space habitat in low Earth orbit as seen from slightly above its X and Y axes. The main body of this habitat is collapsed and folded during launch and then once in orbit inflated like a balloon with a pressurized and breathable atmosphere. It provides a comfortable shirt-sleeve, albeit weightless, environment for several astronauts.
This habitat has an external diameter of about 30 feet and is orbiting the Earth at an altitude of about 250 miles.
