NASA is pressing forward on assessing the value of a "human-tended waypoint" near the far side of the moon — one that would embrace international partnerships as well as commercial and academic participation.
According to a Feb. 3 memo from William Gerstenmaier, NASA's associate administrator for human exploration and operations, a team is being formed to develop a cohesive plan for exploring a spot in space known as the Earth-moon libration point 2 (EML-2).
Libration points, also known as Lagrangian points, are places in space where the combined gravitational pull of two large masses roughly balance each other out, allowing spacecraft to essentially "park" there.
A pre-memo NASA appraisal of EML-2, which is near the lunar far side, has spotlighted this destination as the "leading option" for a near-term exploration capability. [Gallery: Visions of Deep-Space Station Missions]
