We'll soon know what kinds of crops we can grow on Mars! Bonus, the fruits will be already freeze-dried!

Dissolved Products of Artificially Pulverized Silicate Minerals and Rocks: Part II W. D. Keller, A. L. Reesman Journal of Sedimentary Research Volume 33 (1963) ABSTRACT Indeed, slightly basic pH (8.2 to 9.2) is reported by these authors for most silicate rocks. More recent literature anyone ? PS. It seems we were all biased by the "past acidic conditions" and the tons of sulfates at Meridiani :-) |

It seems we were all biased by... Except those of us who can barely remember from school which side of 7 is basic and which side is acidic, nevermind guessing what the conditions on Mars might be! It may be worth stressing that at the briefing they pointed out that conditions may vary considerably with depth or with location on Mars. Today's result is likely just one data point rather than "the answer" to what the pH is on Mars. |
