Wonder if degradation of near-surface organic compounds over time is also addressed by this paper. If there is in fact anything there (even down deep), you'd think that there would be detectable organic residue within our reach due to various regolith mixing processes (esp. in the polar areas), unless the radiation environment is just too severe for them to survive... -------------------- A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.
