Extraction of Water from Polar Lunar Permafrost with Microwaves - Dielectric Property Measurements [PDF]

, 2009
Remote sensing indicates the presence of hydrogen rich regions associated with the lunar poles. The logical hypothesis is that there is cryogenically trapped water ice located in craters at the lunar poles.

The effects of lunar dust accumulation on the performance of photovoltaic arrays [PDF]

Lunar base activity, particularly rocket launch and landing, will suspend and transport lunar dust. From preliminary models, the resulting dust accumulation can be significant, even as far as 2 km from the source.
