re: Venusian atmosphere is supercritical at lower altitudes

Interesting, used in everything from dry cleaning to rock drilling to extracting herbal essences.

I can see what you mean about wierd chemistry. Supercritical CO2 will dissolve magnesium easily according to one article (don't use for spacecraft components!), and is extremely good at disolving anything organic out of rocks. In fact, I'm surprised the Venera photos showed rocks that looked so unweathered, given what supercritical CO2 seems capable of doing.

Good tip!
