Reading the following questions and their answers:
- Why wasn't the phosphine in Venus' atmosphere detected by space probes?
- Phosphine, yes -- but where are the organic compounds on Venus?
the second provides a link that, "phosphine is no more." However, my imagination was thinking elsewhere -- the Earth. Chlorine-m34 arises from cosmic ray spallation on Argon.
By analogy, could phosphorus arise from cosmic ray spallation on sulfur in sulfur dioxide, sulfuric acid or hydrogen sulfide?
(Space Exploration aspect) Or fantasy again, in future human floating settlement, shall human explore this following option to supply phosphorus to the settlement or station? Packages of Venusian atmospheric sulfur species are exposed in the path where most incoming cosmic rays shine to make more phosphorus. The phosphorus are then mined.
