NASA Dreams of Floating Space Station Twixt Earth and Moon

The U.S. National Aeronautics and Space Administration is looking into setting up a base near the moon to further space exploration. As it's envisioned, the base will go into a halo orbit of the Earth-moon libration point 2, known as "EM L-2," above the far side of the moon. Essentially, a spacecraft in a halo orbit goes around and around near a libration, or Lagrangian, point -- in this case E-M L2.
