Luna C/I: Moon Colonization and Integration
In what seems to be a little-noticed but highly important development for lunar base planning, Japan’s SELENE (also known as Kaguya) lunar orbiter last month determined that the concept of a ‘Peak of Eternal Light‘ at either of the lunar poles does not exist.
The possibility of a Peak of Eternal Light at one of several locations, including the rim of Shackleton Crater or on Malapert (both at the South Pole), made those locations prime candidates for early lunar bases. Having eternal sunlight is, clearly, an advantage for any outpost relying largely on solar power.
Some of these points at the lunar poles do have as much as 89% illumination, though, so they remain very strong locations as far as near-constant solar power.
The JAXA team’s findings were published in the U.S. journal of Geophysics last month.
