Karst is a Farst?

November 30, 2012

All, this is a very nice blog discussing sinkholes and caves on the moon.  I would think we could assume these were not created by the same processes geologists believe our Earthly sinkholes are created, i.e. by carbonic acid, sulfide oxidation, hydrology, pseudokarst morphology mumbo jumbo?  In other words I believe in most instances, Karst is a Farst (I made up a new word along with new science).

I believe our planet and the universe has been transformed over the millenia by orbital dark matter and beta decay and this will continue.  The rate will depend upon the density of local orbiting dark matter, which appears to fluctuate based upon the weak anthropic principle.  We happen to be extremely fortunate to live in a period in our part of the universe  where it is currently in check.  I hope this does not change rapidly from some carpet-bombing comets or our sun having a bad spell.  Count your blessings.

Godspeed

Motivation:
Lunar caves are very interesting for the standard reasons (they offer possible locations for radiation-proof, thermally-benign bases for future astronauts).  Another reason of interest is that there are so few of them… there are only three officially recognized ones!  The Japanese Space Agency’s Kaguya lunar orbiter had found these three caves using its imager and these were later confirmed by LRO images.  LRO, having better resolution than Kaguya, provides the possibility of finding other smaller caves or simply caves illuminated at different sun angles.

I am a NASA engineer who works the design of space power systems and have done some lunar polar illumination analyses (papers here, here, and here) supporting the Constellation Lunar Surface Systems program.  These analyses are used to optimally size the solar arrays and energy storage systems for spacecraft including landers, bases or rovers near the poles.  During the acquisition of LRO NAC…
