The Future of Space Stations

"The Future of Space Stations"," However, most people don't realize the fact that this requires a lot of preparation and logistics in order to make it happen.
 This is especially important, as launching any important mission from Earth's gravity well is a difficult prospect.
 However, with the utilization of space stations in the orbit around the Earth, it could become possible to launch these missions from outside the Earth's gravity well.
 In essence, LEO is officially defined as the space in between 100 km of altitude to 500 km altitude.
 Up to 500 Km is defined as LEO and from 500 to 1000 is defined as Middle Earth orbit (MEO) and above 1000 km is defined as High Earth orbit or HEO.
 Technically, some atmosphere remains at that altitude and although it is not breathable, drag effects do occur due to molecular flow of particles hitting the outer shell of the International Space Station.

Because it is cheaper to put something at that altitude, it is easier to put a space station at LEO.
 However, gradually there may be new space stations that will be present in higher orbits as well so that they can be used as stepping stones for intra solar destinations.
 Artificial gravity can be created through the use of some part accelerating in a rotating manner.
 As science advances and as more experience is gained with space stations, it may even become possible to create space habitats some day.
