Permanent station between the Earth and the Moon - Artist view - Lunar cycler at apogee - Artist view - Lunar Cycler is a space station placed in orbit between the Earth and the Moon whose trajectory would alternate between the Moon and the Earth. Once positioned in orbit, this gravitational assistance vessel would use very little fuel. This project would make a permanent link between the two stars. A lunar cycler has reached its furthest orbital point from the Earth - the apogee - and is rounding the far side of the Moon to begin its fall back towards Earth. At apogee the lunar cycler is about 300 thousand miles from the Earth and 50 thousand miles beyond the orbit of the Moon (further from Earth than any human has ventured yet). If frequent manned trips to the Moon become a reality, the earlier “” throw-away”” technologies of the Apollo lunar missions will be impractical for the long term. More efficient and reusable systems will need to be developed in order to minimize the labor and resources required for these extraordinary voyages. A journey to the Moon can be broken down into three basic tasks: transfer between the Earth's surface and Earth orbit, transfer between Earth orbit and lunar orbit, and transfer between lunar orbit and the Moon's surface. While the simplest solution may be a single vehicle that could do all three, no technology today or in the foreseeable future can meet all these needs. One solution would be to dedicate separate vehicles for each the three tasks. A reusable space shuttle would lift explorers off the Earth's surface, a dedicated and reusable lunar shuttle would deliver explorers to the Moon's surface and back, and in between there would be a kind of orbital way station. One such way station is known as an orbital cycler. An orbital cycler is a vehicle that's in a permanent orbit around two celestial masses. In the case of a lunar cycler, the orbit would include both the Eart
